...Cooler
and Drier Over Entire Region ...
...Tornadoes
Strike at Northern Virginia...
The big event
of an otherwise unremarkable "weather month" was the tornadic outbreak
of the 24th. One summary is included below but your best look at
the storm can be found at the link provided below to NWS WBC's homepage.
Numerous pics, maps, and graphs as well as in-depth text coverage are presented.
On whole, the
month was pretty non-descript weatherwise... simply drier and cooler than
normal for most of us. A few exceptions in the rainfall category
are noted and generally result from excess rainfall coming in thunderstorms.
Without those downpours, everyone would have noted dry conditions.
But in a time
such as we continue to endure since September 11th, 2001, the weather is
of little importance. We do extend our sincere sympathies to the
families whose homes and property were destroyed in the 24th tornadoes
and to the families of the two students who died on campus at the University
of Maryland in College Park as the outbreak came to an end.

...Tornado Details
from Culpeper and Fauquier Counties... A second national weather service
storm damage survey team from the Sterling office went to Culpeper and
Fauquier Counties in Virginia today (9/25). A ground survey was conducted
to assess damage caused by a tornadic thunderstorm that occurred Monday,
September 24th.
The worst tornado
damage occurred about 2 miles northeast of Rixeyville in north central
Culpeper County Virginia. There a large 3 story house located on
Indian Fork Road just off Oak Shade Road (Route 624) was completely leveled.
This house was solidly constructed having a brick wall exterior. The survey
team has rated this tornado as a minimal F-4 on the Fujita scale. An F-4
tornado has maximum winds between 207 and 260 mph but in this case winds
were likely near the lower range of this rating category. The first 911
call indicating the house had been struck by a tornado was received at
the Culpeper County Emergency Operations Center at 3:08 PM EDT. The tornado
was about 75 yards wide at this point. Significant pieces of the house...such
as upstairs roofing trusses...were found up to one half mile to the northeast.
This tornado
apparently had first set down in Rixeyville where a tree was blown onto
a home on Ryland Chapel Road (Route 640) shortly after 3 PM. The tornado
was rated F-0 (40-74 mph) at this point. The tornado continued moving northeast
and after demolishing the house on Indian Fork caused extensive damage
around the community of Jeffersonton. The tornado caused F-1 damage
(75-112 mph) in the Ponderosa Trailer Park on the south side of Jeffersonton
destroying three trailers and damaging four others. Four churches in town
were also damaged with two churches experiencing moderate roof damage.
The tornado was rated F-1 as well around Jeffersonton. Significant tree
damage also occurred along the path. As the tornado moved northeast...it
demolished a large garage and rear porch attached to a two-story house
on Springs Road (Route 802) about 1/4 mile northeast of Jeffersonton. This
house also lost a portion of its roof and an adjacent house lost the roof
to an attached sun room. The tornado was rated F-2 at this location. An
F-2 tornado has maximum winds between 113 and 157 mph.
Damage from
the tornado lessened about one half mile northeast of Jeffersonton as the
storm crossed the Rappahannock River into Fauquier County. Only scattered
minor tree damage (rated F-0) was noted in the 9100 block of Harts Mill
Road (Route 688) in Fauquier County.
Pieces of a
tin roof from a small utility shed or barn were found in an open field
along Route 211 about one-quarter mile east of Holtzclaw Road (Route 681)
in Fauquier County (F-0 damage here). The tornado appeared to lift after
it crossed Route 211 near Atherton Farms. At this time no damage reports
have been received along the path of the storm from where the tornado lifted
near Routes 211 and 681 until just west of The Plains Virginia.
The team surveyed
tornado damage in northeastern Fauquier County in the vicinity of The Plains
Virginia. A house near the intersection of John Marshall Hwy. (route 55)
and Bunker Hill Road...about one-half mile west of The Plains...was struck
by a tornado around 350 pm EDT. The tornado caused extensive tree and powerline
damage around a well-constructed 2-story brick house. The tornado ripped
off a large front porch from and blew it 50 feet away. Lumber pieces from
the porch were hurled into vehicles parked next to this residence. The
tornado was rated F-1 here and was between 50 to 100 yards wide. Many of
the slate shingles were blown off the roof and a small pool house was destroyed
at this location.
Damage...mainly
to trees...from this tornado was followed to the northeast along Whitewood
Road.
F-0 damage was
observed to a small horse barn on Milestone Road. The survey team also
found tree damage along Rock Hill Mill Road between Whitewood and Zulla
Road.
No survey was
conducted north of Rock Hill Mill Road but it is possible that the tornado
may have continued producing damage northward to the Fauquier-Loudoun Counties
line. At this time no damage has been reported in Loudoun County near the
path of this storm.

SUMMARY OF
CLIMATOLOGICAL DATA
SEPTEMBER
2001
Patrick Maloit's SEPTEMBER
2001 Hydrological Report Narrative Summary http://tgsv5.nws.noaa.gov/er/akq/HYM/SepPre2001.htm
"September was
drier than normal across most of central...south central and eastern
Virginia, northeast North Carolina and the the lower Maryland eastern shore.
Dry September's are typical across the area without the impact of a tropical
system. The month was marked by several dry spells, punctuated by areas
of heavy rainfall associated with some of the seven cold fronts that moved
across the Mid-Atlantic states in September. September 2001 precipitation
totals ranged from 0.75 inches at Gordonsville (Louisa)...to 4.38 inches
at Hallieford (Mathews). A cold front crossed the area on the 1st...causing
scattered showers and thunderstorms with it. This precipitation caused
a 24 hour maxima for the month of 0.25 inches at Nurkeville (Nottoway).
High pressure built in from the Great Lakes behind the front...gradually
moving east to off the Canadian coast on the 3rd. A cold front moved from
the Great Lakes on the 4th to off the East Coast by the 5th...bringing
generally light precipitation with its passage. An area of high pressure
slowly moved from the lower Great Lakes late on the 5th to off the New
England coast on the 9th. Showers and thunderstorms developed in the deep
southerly flow that developed behind the departing high...and ahead of
a slow moving cold front on the 9th. With another batch with the passage
of the front from the 10th to the 11th. This 3 day period of scattered
showers and
thunderstorms
caused a few 24 hour rainfall maxima for September including: 1 inch at
Clarksville (Mecklenburg/9th)...0.73 inches at Lawrenceville (Brunswick/9-10th)...and
2.8 inches at Emporia Water Plant (Greensville/10-11th). On the 11th...a
high built in behind the front from the midwest. This high
slowly moved off the Mid-Atlantic coast by the 13th. A relatively dry cold
front moved across the area from the 13th to the 14th...causing mainly
scattered rain showers with it. Yet another high slowly built in from the
Great Lakes on the 14th...where it remained through the 16th. The high
then slowly moved east...to off the Eastern seaboard by the 19th.
Much like the
period from the 9th to the 11th...the period from the 19th to the 21st
saw several periods of showers and thunderstorms. This was in response
to deep southerly flow behind the high on the 19th and the passage of a
cold front from the 20th to the 21st. The precipitation that occurred over
these 3 days caused some 24 hour precipitation maxima for the month including:
1.47 inches at Back Bay Wildlife Refuge (Virginia Beach/19-20th)...1.52
inches at Ruther Glen
(Caroline/20th)...2.09
inches at Warsaw (Richmond County/20th-21st)...and 0.35 inches at Powhatan
(Powhatan/21st). Weak high pressure built in behind the front on
the 21st...followed
by a relatively
dry cold front passage on the 22nd. Behind this front...high pressure built
in to the Mid-Atlantic states by the 23rd...then offshore by the 24th.
A strong cold front crossed the
area from the
24th to the 25th...causing the majority of the reported 24 hour rainfall
maxima for September. This included Western Branch (Chesapeake/24th)...2.60
inches at the Milford Haven
Coast Guard
Station (Mathews/24-25th)...and 1.70 inches at Camp Peary (James City County/25th).
High pressure moved in from the upper Great Lakes on the 25th...then
moved southeast
to off the Georgia Coast by the 27th. A weak cold front crossed the region
from the 27th to the 28th...causing light precipitation with its passage.
Yet another high built in from the Great Lakes behind this front...sliding
slowly southeast to the Ohio Valley by the 30th. The passage of an upper
level low from the 29th into the 30th...spread light precipitation across
the Northern Neck and Eastern Shore to close the month. Summer 2001
rainfall totals were below normal to normal across most of central...south
central and eastern Virginia...northeast North Carolina...and the the lower
Maryland eastern shore. The totals ranged from 8.60 inches at Assateague
Island (Worcester)...to 20.08 inches at Camp Peary (James City County)."
Snowfall
Our first snowfall
measurements have come in from Dave Lesher in Canaan Heights. So,
'tis time to restart your totals for 2001-2002. We tally seasonal
snowfalls in these reports; so, if you keep yearly totals, please adjust
for seasonal amounts and report those as well.

Virginia:
Annandale - "September
was cool with a -2.2°F mean temperature departure and a little on the
dry side with a precipitation departure of 0.85 inches. The highest temperature
for month was 83°F, which was the lowest maximum for September since
1992. The highest minimum temperature of 67°F was the lowest in September
since 1989 when it was 63°F. The highest temperature range for any
day of month was 22°F, which was the most in September since 1996 when
it was also 22°F. The mean temperature for month of 65.45°F was
the lowest in September since 1994. The highest mean temperature for any
day of month was 75°F, which was the lowest in September since 1989.
The highest wind for month was only 18mph on the 25th, which was the lowest
maximum wind speed for September since 1995. September 24th a tornado passed
only 3.25 miles to the SE of this station. What made the tornado
more unusual? 1. There was very little lightning associated with
the storm and then only at the tornado's passing to our SE
2. Having two strong tornadoes of F3 or F4 in late September --The other
tornado in Culpeper, and The Plains, Virginia 3. Having tornadoes
in this area to make such a long path of destruction 4. Having a
tornado of F3 to F4 strength in the Washington area 9-14-2001--Low
maximum temperature The maximum temperature today was 68°F, and equaled
the 21-year low maximum temperature record for the date; the old record
was set in 1996. 9-15-2001--Fall like weather The 47° minimum
temperature today was the lowest since May 14, 2001. It was also only two
degrees from equaling the 21-year record low minimum for the date
at this station. 9-16-2001--Cool weather The 49° minimum
was only four degrees from equaling the 21-year record low minimum for
the date at this station.The maximum temperature today was 66°F, a
new 21-year low maximum temperature record for the date; the old record
was 70°F in 1996. 9-26-2001--Record low minimum The minimum temperature
today was 43°F, a new 21-year low minimum temperature record for the
date; the old record was 46°F in 1983. It was also the
lowest minimum since 5-7-2001 when the minimum was 40°F." [ -
- ] - notes form Lowell
Arlington - NWS WBC reports:
"No new records were set in Washington this month. After a cooler
than normal summer...September continued on the same track. This
month was nearly two and a half degrees cooler than normal...which ties
it for the third coolest september in the past 25 years. This also
follows the pattern from last September which was the coolest September
in 25 years. There were no days that were 90 degrees or warmer this
month. This likely means that we will end up with sixteen 90 degree
days this year which is less than half of our normal of thirty eight.
Although summer was wetter than normal...the end of summer was relatively
dry...a trend that continued into September which had less than an inch
and a half of rain all month. This was almost two inches below the
normal and was our driest September in ten years. One notable weather
event this month was a tornado that tracked north across the metro area
and the District on Monday the 24th. An energetic system moving east
across the region spun up a tornado that tracked from Franconia in Fairfax
County Virginia...through Alexandria...past the Pentagon and into the District.
The tornado dissipated briefly before reforming around College Park Maryland.
It then tracked through Beltsville to Laurel Maryland. This storm
produced numerous injuries...two fatalities...and millions of dollars in
damages." The average winds speed was 8.3 mph. [ - -]
Ashburn - Notes from Gary:
"Needless to say, the two tornadoes that hit the area on the 24th were
certainly the highlight this month. Last month I gloated about being
out of town on business travel and missing the heat wave in early August;
this month I was on a train to Miami on business and missed the severe
weather on the 24th (though I did get to watch some strong thunderstorms
and high winds in south Florida.) We did get 3.06 of rain that day,
with an additional 1.16 the next day. Temperatures for the month
ran 1.5° F below normal, and rainfall was again above normal, this
time 1.41 above the norm. Quite a few days of dense fog (Im using
visibility of ¼ mile or less to define dense; if this is wrong,
please let me know... [Editor's note: That is the NWS standard; but
great variations in dense fog criteria persist!] ), but only two days
of thunder one of which produced the two tornados; one was less than
13 miles from my station. Wind is picking up just a bit, with more
breezy days than in the past two months, even though the average wind
speed remained at 1.2 mph (vs. 1.2 mph in July and 1.1 in August).
The 18th was kind of interesting in its normality; with a mean temperature
of exactly 65.0° F, there were 5.1 heating degree days and 5.1 cooling
degree days (using the integration method). Three days had their
lows at or around midnight rather than the more typical ~6:30 a.m.; the
10th, the 14th, and the 25th." [ - + ]
Blacksburg - Temps were 1.8°
below normal while precip was 1.77" below normal. - NWS Blacksburg [

Bridgewater - Clayton writes:
" The average temperature was 0.5° below normal. The precipitation
was 2.18 inches below normal. For the year, precipitation is 4.83 inches
below normal. There were no thunderstorms during the month.
Weatherwise, September was a rather dull month!." [ - -]
Centreville - Paul notes: "Since
the first of the year, seven months have had a 24-hour precipitation event
that exceeded one inch. Four of those nine months had occurrences
when accumulations accounted for over half of the monthly total.
September should be included as a major contributor to these facts with
the storm of the 24th and 25th producing 1.84 and 71% of the 2.60 monthly
total. Unfortunately, 2.60 was only 80% of our expected 3.26, being
0.66 short at the last tip of the bucket. The first half to September
held the majority of average highs and lows ranging from 76° to 52°.
A peak of 85° for the month was recorded on the 10th and 38°, the
lowest on the 26th. Even if the lowest temperature had come in at
the average expected low of 55.4°, the monthly average nightly low
would have still worked out to be below normal. After all the buttons
were pushed, we managed to be 2.7° below average. A near milestone
in weather keeping for the century and possibly worthy of a special on
P.B.S." [ - - ]

"September 2001 was a cool and dry month. I had no days with and
inch or more of rainfall. On the 24th, severe weather and strong
tornadoes plagued our area. A warning was issued for Falls Church
around 4 PM. The tornado passed further SE of me and headed towards
Alexandria and the Pentagon. From there it gained strength to an
F4 and moved into College Park, MD." - notes from Erica [ - - ]
Harrisonburg - "The temperature
for the month of September averages .9° below normal. Rain for the
month totaling 1.13" made September the second driest month so far for
2001. This makes the yearly rain total 5.39" below normal." - notes from
Terry [ - - ]
Herndon - Russ sends these
email notes: "September rainfall was .21 inches below normal. I had
thunderstorms on the 10th and 20th. We had fog on the 22nd. Temperatures
were cool, averaging 2.3° below normal. Of note was the 1.79
inches of rain 24th, with no thunder heard, and
the absence of any 90° temperatures
in September. In fact, temperatures stayed below 85° for the
last summer month." [ - -]
Louisa - Continues to get dry
there reports Joe. Nothing of much significance to report in central

Lexington - "Rather dry month
here in the Shenandoah Valley of Virginia. Devoid of tropical systems,
we usually are under 2.5 inches of rain in September. This month our total
was only 1.54 inches...well below average. Of note in September was the
fact we recorded measurable precipitation on only five days; again, below
the average of eight. September's mean temperature was 1.9° below
average and for the first time since March, 2001, we did not record a high
temperature of 90° or above. A colder than anticipated
FROPA on the 25th provided lows in the 30's from the 26th through
