SUMMARY OF CLIMATOLOGICAL DATA 
APRIL 2004

...SOMEWHAT WARMER THAN USUAL FOR MOST
RAINFALL VARIES CONSIDERABLY...

The area - according to your and NWS data below - enjoyed warmer temps than those normally experienced in April with the greatest departures of +1-2 in Virginia and North Carolina. In South Carolina, temperatures were slightly above normal, from a few tenths of a degree to +1.2 in excess of normal for the Greenville-Spartanburg area.

Very difficult to mass-label the rainfall amounts as the departures were "all over the place" throughout the region. Excess precip noted in northern areas of Virginia while the western and southern sections were drier than normal. North Carolina was generally drier with the Raleigh-to-Roxboro corridor experiencing slightly above normal rainfall. Except for Charleston on the coast, much of South Carolina was below to moderately below normal with regard to rainfall.

A rather long period of above normal temps noted from beginning Mid-April as a strong high pressure ridge built across the region. A cold front heading down the coastal plain and inland returned the area to cooler temps later in the month. Interestingly, the hilly, mountainous western areas of NC did not drop to or below the freezing level the entire month; yet, low temperatures dropped to or below freezing at Charlotte, Raleigh, Lumberton, and Wilmington on April 6th, attributed to radiational cooling. At the same time, light winds were noted in and near the mountains stirring the air enough to keep temps from falling to the freezing level.

Annandale - Lowell writes:" April was the first month of the year with above average precipitation and was also a little above average in temperature. April's mean monthly temperature of 56.0 was + 0.6 warmer than the average. The occurrence of a 90 maximum temperature on April 19th at 1412 was only the sixth time in the last 24 years that the maximum temperature was 90F or above in the month of April. April had some large temperature swings and on two days the minimum temperature went below freezing for the first time since 1997. We had a wind chill of 15.5 and a dew point of 4.4 with a 29 minimum temperature on April 5th. The average daily temperature range for April was only 18.9 which is the lowest for April since 1987 that holds the record at 18.1. April rainfall of 5.03 inches was the fourth wettest April in the last 24 years with a +1.60 inch departure from the average. Precipitation occurred on 14 days equaling the 24-year record for the greatest number of days with precipitation in April and the most since 1983. The maximum gust of 44 mph from the west on the 4th at 1320 was the strongest wind gust recorded for April since 1997. The maximum lowest barometric pressure was 29.46 inches on the 1st of April that was the lowest pressure recorded in April since 1999. The first thunderstorm of the year occurred on April 23rd and was the latest first thunderstorm of the year since thunder records were started at this station in 1995.

Arlington - NWS WBC reports: " NO RECORDS WERE BROKEN AT WASHINGTON NATIONAL AIRPORT IN APRIL. APRIL 2004 WAS A SLIGHTLY WETTER AND WARMER MONTH THAN NORMAL IN THE NATION'S CAPITAL. PRECIPITATION TOTALLED ABOUT AN INCH ABOVE NORMAL WHILE TEMPERATURES AVERAGED ABOUT A DEGREE ABOVE NORMAL. A WARM SPELL OCCURRED FROM THE 17TH TO THE 23RD. HIGH TEMPERATURES DURING THAT PERIOD WERE AT OR ABOVE 75 EACH DAY. THE WARMEST DAY BEING THE 19TH WHEN THE MERCURY REACHED 91. THE LONGEST DRY SPELL DURING THE MONTH OCCURRED FROM THE 15TH TO THE 22ND. NO MEASUREABLE PRECIPITATION WAS RECORDED DURING THAT PERIOD. " [ + + ] 

Bridgewater - " There were no thunderstorms during the month of April. In fact, we haven't had a thunderstorm all year in Bridgewater. The last year for a first thunderstorm this late was in 1997 when the first one occurred on May 9. In 1988, there were 8 that occurred before May 1." - report from Clayton [ + + ] 

Centreville - " With a blizzard and hurricane Isabel capturing the weather headlines last year, 2004 seemed to be off to a slow start with not much more than a "ho-hum" snowflake to account for. This April brought a spark of excitement (although not enough to call in the medics.) to many of us cloud gazers when the record high temperature for April of 93 set in 1990 was challenged by our 92 on the 19th. Although not enough for a spot in first place, we did manage to tie for the silver when another reading of 92 was recorded, also in 1990. All together, this April was a warm month with the average monthly temperature of 57.7 a full five degrees above the 52.7`statistical standing. While the average daily high came in at 2.3 over the 65.2 normal average, the lows took its best shot at challenging the status quo. The record books stated an average low of 40.2 for April, but we logged 47.9 for our nighttime average low; a full 7.7 above normal, and the greatest difference above the average so far this year. This month also claims another second place award. This time it is for the second highest low of 31 which happened to match the second place reading recorded in 1979. The greatest rain event of April started at 0800 on the 12th when 1.52" fell over a 15 hour period and accounted for nearly a third of our precipitation for the month. Our rain gauges greatly deserve our collective applause by accumulating 4.76" without any help from snowfall and exceeding the 3.44" normal monthly average rainfall by 1.32. The trend since the first of the year for monthly rain accumulation to be below average was finally offset by an April surplus bringing our annual accumulations to three-quarters of normal, or logging a deficit of 3.26". " - notes from Paul [ + + ] 

Falls Church - " April 2004 was about average in temperature and above average in rainfall. The most unusual thing about this month is that I had my first 80 day and first 90 day in the same month and within 2 days apart from each other. That hasn't happened since I've been keeping records, which go back to March 1994. " - report from Erica [ +/- + ]

Herndon - Notes from Russ:" April was warmer and wetter than normal. The monthly temperature was 1.9 above average and precipitation was 2.19" above average. I think it's safe to say we've ended the snow season, with a total of 19.5". Now it's time for thunderstorms. We had one rumble by on the 23rd and another on the 27th, with gusty winds. " - [ + + ] 

Lexington - Scott sends these notes: " Mean Max for the month was exactly 4 above normal while Mean Min was 2.9 below normal. Monthly rain was 1.52" above normal. As a side note, we are 3.29" below normal precipitation year-to-date, which is about 27% below normal for the year thus far."
