...Warm & Dry...

In a reversal of March 2001 weather (wet and cold), April brought above average temps and below normal precip across the tri-state area of our ACON group and reporting NWS stations.

Alternating cold and warm periods were noted by many of our stations.  In fact, 5 such periods were noted. 

The month began with below normal temperatures for much of the first week, then warmed significantly during the second week.   During the second period, temperatures rose well into the 80s most areas with some lower 90s on the 10th across central Virginia, central and south-central North Carolina, and into South Carolina.  The third significant periodic temperature change came from mid-month to the 20th with some of the month's coldest weather for many stations.  Coldest readings were reported in the mid 20s to lower 30s.  Frost was noted across the entire tri-state area on the 19th.  Of course, more isolated areas of late season frost were scattered across interior areas later than the 19th.  Temperatures warmed up from the 21st to the 24th but fell again with yet another trough for the final days of the month.

The colder periods were attributed to recurring troughs setting-up along the Eastern Seaboard which quickly ending the short-lived surges of warm air from the west and south.

Rainfall was well below normal for most areas, despite the troughiness over the East from time to time which more often than not induces heavier precipitation.  It is not true this April that the month's showers bring May flowers, although no doubt the latter did occur.  Some stations reported an April where rainfall deficiency placed it among the driest of Aprils over the span of the station database.  Rainfall totals for the year continued below normal at most all stations.  Surprise snowfalls from a trace to 2/10ths of an inch at Asheville (and 1/10th at Woodstock) were noted on the 17th and 18th.  The snow shovel award this past snowfall season goes to Woodstock, Virginia with a reported total of 17.8 inches.

With the lack of April rainfall came abnormally pesky bouts with high pollen counts.

A higher than average number of frontal passages during the month helped trigger a few thunderstorms across the region.  No severe weather of note, however.

Virginia:

Annandale -  Lowell adds these observations: "April  was a warm & dry month- only one april 1985 in the last 21 years was drier. The mean temp.  dep. was +2.0°f.   This Apr. was very similar to 1994 as it was the warmest since '94 & the rainfall was only 0.01 in. More than '94.   We had  90°f on April 9th which was highest in April since 1994.   April had the highest daily temp. Range since 1996.  The highest minimum temperature for the month was 63° which was highest minimum for april since 1994.  It is unusual that we had 12 days with measurable precip. And only five aprils in the last 21 Aprils  have had more days with rain but this April still turned out to be the 2nd driest in 21 years of records.   The 29.64" was the highest min. barometric pressure on April 16 was the highest since 1998.  We had  a 30.66 inch bar. reading on April 29th which as the highest bar. reading recorded in Apr. since 1990."

Arlington - NWS WBC reports: "Mean temps were 1.5° above normal while rainfall was 1.03" below normal."

Blacksburg - Temps were 2.8° above normal while precip was 2.83" below normal. - NWS Blacksburg

Bridgewater - Clayton sends these notes:  "The precipitation for the month was .89 inches below normal. Only .22 inches fell during the last nineteen days. Precipitation is 2.37 inches
below normal for the year. Every month since the first of October has been below normal in precipitation except one.  The temperature for the month was 4.2° degrees above normal. During the first part of the month, there were two days with record-breaking high temperatures. During the later part of the month, there were three days with frost and freezing temperatures. Three thunderstorms occurred on the 19th.

Centreville - Paul writes via email: "With our April precipitation being pretty much on schedule until mid-month, May flowers seemed to be a sure bet.  Then on the 16th, with just a drop over a quarter of an inch of rain through the end of the month, even the dandelions were digging in for a though time.  With 3.14 being our normal monthly precipitation, only 2.03 fell yielding two-thirds of what we should expect.  The average nightly low temperatures were naturally warmer than usual by almost 3.5° while the overall average for April was 2.7° higher than the 53.3° we were all expecting.  The high for April came in at 89° on the 23rd and just four days later 28° was recorded as our lowest temperature for the month.  The average daily high of 67.6° and the average daily low of 44.3° (give or take a couple of tenths) both occurred on April 28th.  With all of its ups and downs, April has fallen out of the running for any awards for this entire century.

Charlottesville - Rainfall for the month was 2.39" below normal. - NWS WBC

Dulles  - NWS WBC reports the mean temp was 2.4° in excess of the norm.  Rainfall was deficient by 0.96".

Falls Church - "April 2001 was slightly warmer than normal but below average in rainfall.  On a few occasions the pollen count reached record levels, over 1,000" - notes from Erica
(Editor's note: "Tell me!  I'm still suffering headaches unlike those of the past!  Whew!!)

Hampton - The month of April brought near normal temps with below normal precip.  Station records included a low max of 50° on the 17th and a record low minimum of 33° on the 19th. - Dave

Herndon - Bob's remarks reminds us it's time to bleach out our Tru-Check rain gauges (or any of those plastic types).

Herndon - "April rainfall was an inch below normal. We had measurable rain on all but one day between the 6th and the 18th, and then the rain stopped for the rest of the month. Temperatures averaged 2.4 degrees above normal, with records highs of 86.9 and 86.3 set on the 9th and 23rd. We tied a record low on the 19th with 28.4. The peak wind gust of 41 was registered in a thunderstorm on the 9th.  We had another thunderstorm on the 10th, which was less severe." - notes from Russ

Lynchburg - The mean temp was 1.3° above normal while precip was 1.81" below the norm. - NWS Blacksburg

New Market - Joyce reports: "Temperature is about 2° above normal for the month and 1° above normal for our lows. This has been a weird month with the ups and downs of the temperature. We roast one day and are cold the next. Furnace on and furnace off.  We are about 1" below the monthly rain level.  We broke 3 high records this month.  On the 9th, 10th, and 23rd.  We also broke 2 low records on the 26th and 29th and tied a record low on the 30th."

Newport News - Gary reports a month of extremes.  Cool for a few days, then warm, then back to cool.  Record lows on the 5th and 18th.  Tied record lows on the 19th and 27th.  Record high on the 9th and tied on the 12th."

Norfolk - From  NWS AKQ:  The monthly precip was 1.58" below normal while the monthly mean temp was 1.1° above normal.  The average wind speed was 9.9 mph.

Portsmouth - Like many of you, I noticed alternating, strong cold and warm periods.  On average the month was slightly warmer (+0.8°) and drier (only 50%) than normal.  Yearly rainfall was over 5" below normal.  The total rainfall was the 4th driest in the 25 year database.   During that time, April was the 9th warmest.  The average wind speed was 5.2 mph from a dominant northerly direction.  The last seasonal frost- a light one - occurred on the 19th.  APRIL RECORDS:  9th - Daily high temperature 87° (previously 86° in 1991); 12th - Daily maximum minimum temperature 58° (previously 55° in 1992); 17th - Tie of daily minimum maximum temperature 49° (previously in 1986); 19th - Daily minimum temperature 34° (previously 35° in 1983); 25th - Daily precipitation 0.71" (previously 0.53" in 2000).

Richmond - According to NWS AKQ:  Richmond's rainfall was 0.82" above normal.  The average wind speed was 8.0 MPH.  Temps averaged 0.9° above normal.

Mechanicsville -  "Downpours on the 17th during the morning and a thunderstorm on the 10th and again on the 24th." -Glenn

Roanoke -  "Temperature averages were 3.8° above normal.  Rainfall was below normal (-2.44") - notes NWS Blacksburg

Roanoke - Warm and dry says Wendell.  This was the 3rd driest April on record and 3.64" below normal!

Woodstock -  "The only notable event in April was a tenth of an inch of snow and ice pellets on the 18th, in the midst of a late cold spell.  Though I had 32 on three successive nights, temperatures were much below that at lower elevations.  Temperatures for April as a whole  were a bit above average, precipitation a bit below. - notes via email from Lauck

North Carolina:
Asheville - From NWS GSP: The monthly mean temp was 3.0o above normal while rainfall  was 2.04" below normal.  The average wind speed was 6.8 mph.

Brevard -  Bob notes: "April 2001 was a warm month, about 2° warmer than the ten-year average. The mean high, 71.8° F, is 1.4°. warmer and the mean low, 44.7° F, is 2.5° warmer. Expected rainfall for April, 4.53"  based upon the ten-year average, is  well above the 1.71" that was actually recorded, increasing the annual deficit to 9.93". While we are
blessed with an average annual rainfall of 67", the region is mountain with underlying rock so that runoff carries the water  away quickly."
Charlotte - NWS GSP reports the mean temp here was 2.0o above normal while precip was 1.50" below normal.  Yearly rainfall totals at the end of April were 3.74" below normal.   The average wind speed was 6.0 mph.

Concord - Tom sends these email notes: "April continued to add to the now Extreme Drought Conditions across the region.   After March ended a string of 6 months of below avg.
precipitation it seems April began a new string. Normal rainfall for the month of April locally is 3.65"; locally I received only 1.10" of rain or about 30% of normal. Mandatory water restrictions are still in place in the immediate area and restrictions will probably get worse before they get better. Rainfall since July 1998 is now 37.23" below normal since the "real"
beginning of the drought. Temperatures averaged 2.6° above average in April and may be setting a trend for the summer and fall of 2001....more dry and hot weather. Not wishing harm or hardship on anyone but a couple of tropical depressions across the region may be our only hope for substantial relief.

Lumberton - The average wind speed was 7.5 MPH.  - from NWS ILM

Raleigh (RAL) - Bob reports: "April was a month of extremes with a high of 91° on the 9th to a trace of snow on the afternoon of the 17th.  Also, we had a hard freeze on April 19th with a 26° temperature."

Roxboro - According to Merriell,  "April brought a variety of all seasons with record heat followed by snow, sleet, rain, and frost/freeze warnings.  Temperatures averaged about 2.5° above normal while the month ended drier than normal."

Wilmington -  From NWS ILM:  The average wind speed was 9.1 mph, the average temperature was 1.5° above normal while rainfall was 1.97" below the norm.  A record high temp was set on the 10th (89°) beating the old record of 86° in 1893.  A high temperature record was tied on the 9th (89°) and on the 13th (89°).

South Carolina:

Columbia - NWS CAE reports the average relative humidity was 62% while the average temperature was 1.8° above normal.  Rainfall was 2.67" below normal.  For the year rainfall is running 6.93" below the normal. - NWS CAE

Charleston - Eleanor sends  these notes: "Another DRY month!!!  But April is the second driest month of the year normally anyway...but even drier than usual.  Records:
Charleston International Airport:  April 13 High temperature  90°, previous record 89 set in 1981; April 18 Low temperature  35 ° previous record 38 set in 1997  Downtown Charleston:
April 3   Low temperature tied  46° previously set in 1965; April 8   High temperature  88° previous record 87 set in 1999; April 10 High temperature  85° previous record 81 set in 1978 April 11 High temperature  83° previous record 80 set in 1952; April 13 High temperature  89° previous record 87 set in 1971; April 18 Low temperature  41° previous record 43 set in 1983.  Though temperatures ran just slightly above normal, April 2001 was a month of extremes, with several temperature records set at both Charleston airport and at the Customs House in downtown Charleston.  April is normally the second driest month in Charleston, but it was abnormally so this past April, with only 35% of normal rainfall for the month.  High pressure remained dominant off the southeast U.S. coast, with only 5 days of measurable rainfall.  With the lack of rainfall and no organized storm systems to speak of that moved across the area, no thunderstorms were recorded during April 2001 at Charleston.  Ironically, the April extreme monthly temperatures ended up being daily records on the 13th and 18th."
Florence - NWS ILM reports the mean temp there was  1.7o above normal while rainfall was 2.53" below normal.  The average wind speed was 7.7 mph.  Records: Record highs.. 90° on the 9th (previous 88°/1965) and 93° on the 10th (previous 90°/1995); High temp record ties... 92° on the 11th and 88° on the 13th; Record lows... 63° on the 18th (previous 36°/1983) and 43° on the 26th (previous 44°/1995).
Greenville-Spartanburg - The monthly temps averaged 2.2o above normal while total rainfall was 2.76" below normal.   Yearly precip was running 4.65" below normal.   The average wind speed was 7.3 mph.  - NWS GSP
North Myrtle Beach - From NWS ILM:  Rainfall was 1.68" below normal.  Temps averaged 0.2o below normal.  The average wind speed was 8.2 MPH.   Records: High temp set on the 13th (88°) beating old record 85° in 1995; record low temps set on the 18th (35°) beating 36° in 1951; 19th (32°) surpassing the 37° in 1997; 26th (42°) beating 43° set in 1949; and on the 27th (38°) surpassing the 42° in 1993.

Orangeburg - The average relative humidity was 67%. (from NWS CAE)
