...LYNCHBURG & CHARLESTON HAVE COLDEST DECEMBER EVER!!.. ..HEAVY SNOWS COVER PARTS OF NE NC & INTERIOR SE VA.. There is simply nothing more to add, particularly since your reports and Patrick Maloit's summary cover everything quite well. Assessing your and NWS reports, the entire area saw its mean temperature average a whopping 7 degrees below normal! Fortuantely, moisture was deficient so we didn't see above average snows except for a period of heavy snow over NE NC and interior SE VA. In his December NWS narrative hydrologic report for the Wakefield forecast area, Patrick Maloit wrote: "December had near normal precipitation across most of the Virginia Piedmont and Central and South Central Virginia...but below normal rainfall across Southeast Virginia...Northeast North Carolina...and the Virginia and Lower Maryland Eastern Shores. The bulk of the precipitation occurred during a stormy period around the middle of the month...while most coastal lows stayed either to our south or out to seas...keeping coastal locations drier than normal. December was cooler than normal as well...as Canadian high pressure was the rule between storm systems...allowing for most locations to receive accumulating snowfall. December began with Canadian high pressure building into the region from Canada...with the high arcing from Minnesota into New York on the second...as an area of low pressure developed along the Gulf Coast. The low moved to off the Carolina coast by the morning of the 3rd spreading with it a significant snowfall across Northeast North Carolina...and extreme south portions of Southeast Virginia...as it moved northeast. Snowfall totals ranged from 15 inches at Aulander in Bertie County North Carolina...to a dusting across Northern Suffolk...Portsmouth...and Norfolk. No snow fell across the Delmarva Peninsula or Central Virginia from this storm. It also produced the 24 hour precipitation maxima for the month at many locations across Northeast North Carolina and the southern Tidewater area...including 1 inch at Wallaceton-Lake Drummond in Chesapeake. Cold high pressure continued to build in from the northwest on the 4th...moving offshore on the 5th. A cold front crossed the region late on the 5th producing light precipitation across the region. Yet another Canadian high built in from the plains behind the front on the 6th...moving to Southeast Georgia by the 8th. Another relatively dry cold front cut across the region late on the 8th...followed by more arctic high pressure...and remained the region's dominant weather player through the 10th. Another dry cold front passed through late on the 10th...and interacted with a coastal front...to produce scattered light rain and snow across coastal regions the night of the 10th into the 11th...including a monthly maxima of 0.33 inches in the West Cradock section of Portsmouth. The low was followed by weak high pressure over the Mid-Atlantic States. This high held through the 12th...when yet another dry cold front crossed the region. High pressure built in from Pennsylvania on the 13th. On the 14th...a cold front from the Ohio Valley...interacted with a coastal front...producing a mix of snow and rain for the Delmarva...Southeast Virginia...and Northeast North Carolina...including several monthly 24 hour maxima...including 0.74 inches at the Salisbury Airport. High pressure moved into Central Pennsylvania on the 15th...as the coastal front remained offshore. The coastal front produced enough precipitation at Eastville on the Eastern Shore to produce its 24 hour maxima for December of 0.33 inches. High pressure remained over the Mid-Atlantic region on the 16th...as low pressure developed off Cape Hatteras. These two features combined to produce copious precipitation over the region from the 16th into the 17th...with many locations receiving at least half of their monthly precipitation. Monthly 24 hour maxima set from the 16th into the 17th ranged from 0.50 inches at Snow Hill on the Maryland Eastern Shore...to 2.75 inches at Colonial Beach on the Northern Neck. A relatively dry cold front moved through the region on the 17th...as the nor'easter turned its eyes on New England. Another Canadian high dominated the region's weather from the 18th into the 19th...before a cold front moved through late on the 19th...spawning a coastal low that caused light snowfall on the Eastern Shore from late on the 19th into the 20th. Yet more high pressure built in from Canada from the 20th into the 21st. On the 22nd...a cold front...once again...interacted with a coastal front to produce light snows across the region. The 8th area of Canadian high pressure to visit the region in December moved in late on the 22nd and dominated the area's weather through Christmas Eve. A weak cold front moved across the region late on the 24th. Christmas Day featured yet another arctic high pressure system building into the Mid-Atlantic states. This high kept the region cold and dry through the day on the 29th. Low pressure developed off the Virginia coast late on the 29th...giving a dusting to an inch of snow along the Eastern Shore as it raced northeast as it strengthened. High pressure built in from Canada on the 30th...and continued to supply cold...dry air to the Mid-Atlantic states to close the month. December 2000 precipitation totals ranged from 0.97 inches at the Norfolk International Airport...the sixth driest December on record...to 4.01 inches at Kilmarnock on the Northern Neck. Snowfall totals ranged from a trace at several locations...to 6 inches at Jackson and Murfreesboro in Northeast North Carolina. December snowfall was unusual in that more snow fell across southern parts of the region...than across northern parts...thanks to the coastal storm of December the 3rd and 4th. |
Here are some interesting sites on the web our members have submitted: From Lowell Koontz: "Good website on snow!! Enjoy!" Tom Myers of Concord, NC (hence CND) has rejoined our ACON group and writes: "My name is Tom Myers and I live in Concord, NC which lies along I85 about 20 miles NE of Charlotte. I love the ACON concept as I enjoy viewing weather statistics from around the Southeast/Mid-Atlantic Region. I have a Davis Weather Monitor II Station and have been keeping weather records for a number of years. At 43 years old I have been observing and studying the weather for as long as I can remember; the Internet has been an absolute gift for older weather observers who now have access to basically anything (what I would have given to have the internet and weather as a teenager!!!!).

Annandale - Lowell sends
these notes: "This Dec. had a dep. of -8.2°F the coldest since Dec.
89 which was the coldest month for any month in more than twenty
years. The total precip. was 2.34 inches, a dep. of -0.89 inches.
There were only six days with precip., the least days since 1988.
The highest December maximum temperature was 57°F, which was the lowest
December maximum temperature since 1989.The highest December minimum temperature
was only 33°F, which was the lowest for December since 1989 a
dep. of -14.0°F. The 12°F minimum temperature on December 23rd
was the lowest December temperature since 1989. This December had
30 days with the minimum temperature <= 32°F. The record is 31 days
set in December 1989. The 3.8 inches of snow in December was the
most since 1993 (then 5.2 inches). The 46 mph wind on December 12th from
the WNW at 0828 was the highest in December since 1993 (then 47mph). The
30.73 inch barometric pressure on December 13th was the highest December
pressure since 1993 (then 30.80 inches)."
Arlington - NWS WBC reports
DCA's mean temp was a whopping 7.6obelow normal while the rainfall
departure was 1.11" below the norm. No records were set.
December 2000 was much colder than normal. In fact,
it was the coldest since 1989. This December tied for the 11th coldest
since records began in 1871. The average wind speed was 9.1
MPH.
Blacksburg/Roanoke/Lynchburg Area
- "The year 2000 was characterized by mild temperatures in southwestern
Virginia...with the exception of the month of December. The first
three months of the year were all
warmer than normal...while the warm season months of July through September
were all below normal. In February...for example...Roanoke and Lynchburg
normally have daily high temperatures at or below 32 degrees on 3 days.
In February 2000 the high every day was above freezing. Conversely, in
the warm months Roanoke normally has 27 days each year when the high reaches
or exceeds 90 degrees...Lynchburg has 23...and Blacksburg has 7 in a normal
year. In 2000 Roanoke reached 90 or higher only 12 times...Lynchburg only
9 times. Blacksburg did not reach 90 at all In 2000. July is normally the
hottest month of the year. In Roanoke normally 10 days reach or exceed
90 degrees. In July 2000 only 3 days reached 90. Similarly...in Lynchburg
8 days are normally at or above 90. This year only 1 day in July reached
90. The greatest departures from normal occurred in February...when monthly
mean temperatures were around 6 degrees above normal...and in December...when
monthly mean temperatures were at least 7 degrees
below normal. Overall...however...the
annual mean temperature in most places was 1 or 2 degrees above normal.
A persistent upper level trough of low pressure over the east...which was
the dominant feature from mid-November through all of December...resulted
in the last 6 weeks of the year being much colder than normal. Although
not as bad as 1999...the year 2000 was also below normal for precipitation.
Most of the area remained abnormally dry to moderate drought conditions...which
increased in severity to the west and to the south.
In Blacksburg...It was a cold and somewhat dry month. It was the 4th coldest December on record...and it was the month with the greatest departure from normal for the year. In a normal December the daily high temperature fails to exceed 32 on 5 days...in December 2000 the high on 12 days remained at or below freezing. The monthly snow fall of 5.1 inches."
Bridgewater - Clayton writes via email: "The average temperature for December was 7.3 degrees below normal. This was the fourth coldest December according to my records of forty years. The precipitation was .57 inches below normal. The first measurable snow of this winter season occurred on the second. We didn't have a white Christmas this year, but it was close. There were patches of snow around, but not enough for me to call it a white Christmas. "
Centreville - Paul send this
report: "Briefly, while looking for neat stuff to report, I thought I could
offer that the high and low barometric pressure of the month occurred within
30 hours of each other. Alas, a greater low of 29.42” came along
four days later, which gave a monthly separation of 1.30” from the high
of 30.72”. Not being able to report the 30-hour highlight didn’t
offer much of a wow! So, I doubt if I’ll even comment on it after
all. Precipitation for December occurred during the middle ten days
with an assortment of rain, sleet, freezing rain, and snow. At the
final bell though, we were able to squeeze out only 70% of the 3.29” normal.
The first snowfall for the season came along on December 19th. With
temperatures generally around freezing for the last half of the month,
we were still showing 1.2” on the snowboard on New Year’s Eve. The
average daily temperature was nearly four degrees below the 35.1 norm.
Even the nighttime low was slightly below our expected 25.3, but I don’t
think I’ll bother to mention that either. Happy New Year everyone!"
Dulles - The monthly precipitation
total, according to NWS WBC, was 1.16" below normal while the average temperature
was deficient by a whopping 7.5o The average wind speed was
6.6 mph.
Falls Church - Erica sends
these notes: "December 2000 was the coldest here since 1989. To this
day we still have patches of snow and ice around from the 12/19/00 storm
that dropped 2" here (Editor's note: notes received the first week of January
2001). Although it has been a cold month, it's been a drier than
average month for rainfall/snowfall. The solar eclipse
on Chritsmas Day was a real treat! Happy New Year to all! May
it be filled with good health and exciting weather."
Fredericksburg - "Colder
than average month, especially the last 2 weeks, which averaged 26o
and
brought 2" of snow. Only 2 morning lows in the entire month remained
abouve freezing." -notes from Ken
Herndon - Russ sends these
notes: "December was unusually cold, averaging 7.5 degrees below normal
for my site. We saw the season's first measurable snow on the 19th (3.6")
and a trace (.1") on the 28th. We had freezing rain on the 13th and 14th
which resulted in 1/4" of ice on the 14th. On the 30th, we missed the much
hyped "snow bomb", which formed too far
east, did not join with a westward
moving storm, formed too late, and quickly moved to New England. At least
we were all prepared."
Herndon - Remarks from Robert Beall: "The year's precip total was close to the 1961-1990 "normal" for Dulles with one record month - the 0.15 total in October. Temperature readings to tenths do not imply significance."
Louisa - "Another dry month. Precip was down over six inches for Y2K. Now it's colder than normal. Cold and dry - when I go out to feed my dog, he raises a dust cloud running in excitement. Is this what it's like in cold deserts - Gobi ?" - from Joe
Lynchburg - From NWS BCB: Recorded mean temperatures were even further below normal than at BCB and ROA. In addition to setting a new daily record low on the 4th...the month of December had the lowest monthly mean temperature ever recorded since records began in Lynchburg...late in the 19th century. In addition...the year 2000 was also the 8th coldest year ever recorded. New daily low temperature records were set 6 times during the year...in contrast to only 1 new record low for Roanoke. 4.2 Inches of snowfall was reported in December...that was almost an inch above normal. The monthly mean temperature was 9.4 deg below normal. Total monthly precipitation 1.72 inches below normal. Records set in December: new record low for the date of 10 on the 4th. Also...the coldest monthly mean temperature...and the 8th coldest annual mean temperature ever recorded.
New Market - Joyce noted: "We had a much colder month than normal. The average for month of December since 1961 is 36.16 and we had 27.61. We had 30 days of 32 or below for min. temperature. This includes 7 days in single digits and 1 day below zero. Precip is normal for this month. For the year, New Market's mean temp of 54.34 was normal. The 39.12" of rain was 4" in excess of the norm."
Newport News - Gary reports:
"Cold. cold, cold!" Also, his 2000 yearly totals reflect an annual
temp of 58.5 and total precip of 49.97".
Norfolk - From NWS AKQ:

lightning. Brief periods of snow on the 20th, 22nd, and 27th."
Roanoke - "This December was
my 2nd coldest at 30.5o . December
1989 at 20o was the coldest. This December's average was
7.7o below normal. This was my first December on record
with all 31 days having a minimum temp of 32o

3.6 inches of snow reported in was 1.2 inches below normal.
The monthly mean temperature was 7.3 deg below normal. Total monthly
precipitation: 1.29 inches below normal. Records set in December:
4th coldest monthly mean temperature."
Vienna - Bob reports: "December was much colder than average. In fact, this was my coldest since 1989. Monthly precip was below average and measurable amounts fell on only five days. Only one snowstorm occurred on the 19th when 3.4” fell. Notably, it stayed cold enough to give northern Virginia a white Christmas! Freezing minimums were recorded on all 31 days. (This hasn’t happened in December here since 1989.) By contrast, only one day (17th) reached at least 50 degrees when, surprisingly, t-storms occurred in the early morning hours. Colder than average weather continued right to the end with a few lonely snowflakes spotted in the afternoon on the 30th.
Some 2000 stats: 2000 avg temp:
54.8F (dep.-0.1F) 2000 total precip: 37.79” (dep.-3.91”) 99-00 season snow:
17.7” (dep.-4.2”) Highest temp: 93F/May 13th Lowest temp: 8F/January 22nd
Note: 2000 saw only 12 days when the temp reached 90F or higher. This was
a record for my location. Accordingly, I recorded my coolest summer (June/July/August)
in the last 14 years."
Washington - Dave reports:
"December was the 2nd coldest month I've recorded in the 10 years I have
been at this location, about 9o below the normal."

"The mean 30 day degree heating days for December, 875 heating DD marks
the month a cold one. Only one December in the past 10 years, 1995, 941
HDD was colder. The ten year average for December is 781 HDD. The mean
high and mean low temperatures were 4.6 and 6.9 degrees below their respective
ten year averages. Precipitation 6.36", including 0.38" from the 9.3" of
snow, was more than double the ten year average for December. The
only December with recorded snowfall in the past ten years was in 1996
when 2.5" fell. The year 2000 was dry, with only 50.04" of precipitation,
compared with a ten year average of 66.92". The mean temperature for the

Concord - Tom sends these notes via email: "The story for December was cold and dry. Another month with precipitation below normal with only 0.96” recorded for the month; this is (-2.01”) below normal. Temperatures were record breaking with Dec 2000 being the 2nd coldest December on record; (-8.0) degrees below normal for the month. Several Winter Storm Warnings (4) were issued during the month with very little or no wintry precipitation recorded; the Warnings were a bust with two occasions of up to 1’ of snow predicted. Result; clear skies and cold weather on both of those occasions. For the year we were again drier than normal with normal rainfall being 46.82”. In the Year 2000 we recorded 37.37” of precipitation; (-9.45”) below normal. This is the 3rd year in a row with rainfall deficits for the area. For the three-year period, 1998-2000, we are (–27.31”) below our normal rainfall. Temps for 2000 were just a little below average at (-0.7) degrees."
Greensboro - NWS RAH reports that no records were set or tied during December. The mean temp was 7.5 degrees below normal while precip was 2.22" below the norm. The mean temp for the year 2000 was normal. The rainfall was 4.05" below normal for the year and the 17.3" of snow in the calendar year was 7.1" in excess of the norm. The station experienced 42 consecutive days of no measurable precip, starting on September 26th and lasting through November 6th. And, as you recall, October was the driest month ever on record.
Lumberton - The average wind speed was 6.8 MPH. - from NWS ILM
Raleigh - "Much colder than normal and drier than normal are the headlines for December. Major snow threat on December 3rd never materialized. The forecast was for 6-12" but only received a trace. Heavy snow did occur well east and northeast of Raleigh. (see map above) Average daily temp was 7.2o below normal."
Raleigh - NWS RDU reports a
new record high on December 17th (69) and a record low was tied on the

normal while the mean temp for the year was just 0.2" below the norm of
59.1. Rainfall for the month was 1.73" below normal and for the year,
2.07" below normal. The calendar year snowfall total of 28.1" was
a whopping 20.2" above the normal annual snowfall. In the year 2000,
a record snowstorm dumbed 20.3" at RDU on January 24-25. Thanks to
this storm, the record for the most snowfall in a 24-hour period (17.9")
and most snowfall in a month (25.8") were set. The airport also experienced
38 consecutive days of no measurable precip, starting on September 27th
and lasting through November 3rd. As a result, October of 2000 was
the driest month ever on record. There were 6 days in which a record
high temp was set or tied and 10 days in which a record low temp was set
or tied. The year ended with December 2000 being the 4th coldest
on record.
Roxboro - Merriell noted:
"Winter's early arrival made December a very cold month. The monthly
average was 7o
below normal. Precipitation
was almost and inch below normal. A threat of severe weather on the
16th and 17th-"
Wilmington - From NWS ILM: The average temp for the month was 7.1 degrees below normal. Although no temp records were broken in the month, this was the 6th coldest December on record.

South Carolina:
Columbia
- NWS CAE reports the monthly mean temp was 8.9o below the norm.
Rainfall was 2.62" below the norm. The year-to-date rainfall

Charleston
- Eleanor sends this summary: "The year 2000 is in the record books, and
several records for the month and year were set. Monthly records:
Charleston International Airport
Low maximum
on the 3rd at 41 degrees, previous 44 set in 1944; Low maximum on the 30th
at 37 degrees, previous 39 set in 1935; Minimum temperature on the 31st

temperature on the 20th at 25 degrees, previous 26 set in 1996; Minimum
tempetature on the 31st at 24 degrees TIED previous of 24 set in 1983.
December 2000 goes down in the record books at Charleston International
Airport as
the COLDEST DECEMBER on record at this location. The average temperature
of 42.6 degrees, which was 8.6 degrees below normal, broke the previous
record of 43.2 degrees, set in the cold month of December 1989. This
average temperature also ties February 1985 for the 6th coldest month on
record. The coldest month recorded at Charleston
International
Airport was January 1977 at 38.7 degrees. Records began at the Charleston
Airport in 1930. There were 18 days when the low temperature equaled
or fell below the
freezing mark
in Charleston in December, which was over half of the total of 34 days
in the year 2000 that dropped to 32 degrees or lower. Also, there were
12 days that did not see the high temperature reach 50 degrees, and one
day that the temperature did not surpass 40 (37 on the 30th). Even
though there were not many cold records temperatures set,
it was consistently
cold throughout the month, which helped to establish the monthly record.
In the year
2000, seven out of the 12 months recorded at or below normal temperatures.
From September through December, temperatures ran at about 3.7 degrees
below the normal for those months, helped by the very cold months of November
(-3.1 degrees) and the record setting December (-8.6 degrees). The
lowest temperature in 2000 was set in December, on New Year's Eve day at
20 degrees, which was a record low for the date. The highest temperature
for the year was set on June 3, 2000, at 100, the only temperature at the
century mark for the entire year. There were 57 days when temperatures
rose to 90 degrees or above. After the dry spell from late September
through early November, which saw a record setting dry month in October
2000 (T), the year rebounded somewhat with a yearly precipitation total
of 45.94 inches, which still ran below normal by 5.59 inches. This
places the year 2000 as the 22nd driest year in the 71 years of record
at Charleston International Airport (1930 to 2000). The driest year
recorded in Charleston was in 1931, during the "dust bowl" years, at 28.80
inches. Of note, the years 1990 (45.13" 17th), 1996 (45.70" 19th),
1999 (46.41" 24th) and 2000 (45.94" 22nd) are listed in the "top 25" driest
years at Charleston
Airport.
When compared to the "dust bowl" years, this is somewhat significant with
the La Nina conditions that have persisted. However, it was much
drier during those years. The years 1930 (32.43" 4th), 1931 (28.80"
1st), 1932 (44.84" 16th), 1934 (38.83" 7th), 1936 (40.20" 8th) and 1938
(31.10" 3rd) are listed in the top 25 driest years. HAPPY 2001!!!
