SUMMARY OF CLIMATOLOGICAL DATA 
APRIL 2005



...TEMPERATURES BELOW NORMAL FOR MUCH OF THE CAROLINAS...

...PRECIPITATION SLIGHTLY BELOW NORMAL FOR MANY
WITH NOTABLE EXCEPTIONS...

Briefly, March and April are usually the transition months from winter to spring with temps beginning to warm nicely. As noted by RAH, there were some significant temperature swings and what warming occurred didn't last very long as temps would cool off as yet one more high pressure would ridge down the coast in the continuing saga of an upper trough carving out over New England and affecting the lower Mid-Atlantic into North Carolina allowing for cooler than normal temps to drop in from Southeastern Canada. The southern storm track was supressed farther south and precip was below normal for the Carolinas. More active weather was observed over the northern half of Virginia where precip totals were above normal. The severe weather outbreaks usually associated with the transition between seasons were almost non-existent through the month.
  • NEW STATION: MEBANE, NC    We are pleased to add Sean McManus to our weather group. Sean's station will be noted as MNC in Mebane, North Carolina. (about halfway between Durham and Burlington, NC just off Interstate 85/40. Sean writes: " What I have for a weather station is a Wireless Davis Instrument Vantage Pro1 and reporting to Davis WeatherLink 5.5.1 software. It is located on my back deck and the anemometer is located above my roofline. My website is at http://www.pipeline.com/~micman2b/Current_Vantage_Pro.htm. I have had a weather station running here for the past three years but the data I have goes back since April 2004. I am also a Datsun 510 enthusiast as well. I own three >1972 Datsun 510's!"

Annandale - Lowell notes: " April was warmer and wetter, windier than average, and had skies that were a little clearer than average. April's mean monthly temperature was + 1.0 F warmer than the 25-year average. The mean monthly temperature was 56.4 F which was the highest since 2002. The lowest minimum temperature was 33 on the 16th which made this April the first April since 1999 not having a day with the temperature freezing or below. The lowest monthly maximum temperature was only 51 F, the highest since 1998, when 53 F was recorded. April rainfall of 4.53 inches was the fifth wettest April in the last 25 years with a +1.03 inch departure from the average. Last year April was the fourth wettest. It was the first time since 1990 we had two days in April with more than one inch of rain and both set new 25-year records for the date. The 1.81 inches of rain that fell in 24 hours on the 1st and 2nd was the greatest 24-hour rain since 2.25 inches was recorded in 2000. The 1.68 inches of rain on the 2nd was also the most on a calendar day in April since 2000 and was the third greatest daily rain in April in the last 25 years. But April's skies were clearer than average and had an average daily temperature range of 22.7 F the highest since 1995. The average ground temperature at one foot was 52.5 F which was the highest in April since 2002. The lowest barometer reading of 29.21 inches on the second was the lowest barometer reading in April since 1982 when a reading of 29.17 inches was recorded. The average barometer reading for the month was 29.94 inches the lowest since 1998 when 29.93 inches was the monthly average. The lowest relative humidity for April of 16% on the 17th was the lowest recorded in April since 2003. The maximum gust of 40 mph from the west on the 3rd at 0940 was the sixth strongest wind gust recorded for April in the past 25 years. Wind run records have been recorded for only the last three years and this April had the highest wind run total. April records included (25-years of records): 1 daily HIGH maximum temp: 6; 1 daily HIGH minimum temp: 7; 2 daily LOW minimum temps: 16, 25; 2 daily HIGH range temps: 5, 10; 1 daily LOW range temps: 22; 2 daily HIGH precip: 2, 30.

Arlington - Report from NWS LWX (Strong): " APRIL 2005 WAS ALL OVER THE BOARD AS SPRING MONTHS TEND TO BE. THERE WAS FLOODING...HAIL...STRONG DAMAGING THUNDERSTORMS...COOL DAYS AND HOT DAYS. IN THE END... IT AVERAGED OUT A BIT WETTER THAN AVERAGE AND A LITTLE WARMER THAN AVERAGE. WITH TEMPERATURES...THERE WERE SHORT PERIODS OF COLD AND HOT EXTREMES...BUT NO LONG EXTENDED COLD SNAPS OR WARM STRETCHES. SOME DAYS WERE MIRED IN THE 50S...WHILE THE WARMEST TEMPERATURE OF THE MONTH WAS A SUMMERLIKE 86 DEGREES. PRECIPITATION WAS WETTER THAN NORMAL. THERE WAS A BIG RAINSTORM TO START THE MONTH AND A BIG RAIN TO END IT. ON THE 1ST THROUGH THE 3RD A LARGE LOW MOVED OVER THE REGION AND PRODUCED OVER TWO INCHES OF RAIN. ON THE 30TH A SLOW MOVING COLD FRONT CROSSED THE AREA LEAVING ANOTHER INCH OF RAIN. IN BETWEEN ON THE 23RD A STRONG COLD FRONT CROSSED THE MID ATLANTIC AND BROUGHT WITH IT A LINE OF STRONG THUNDERSTORMS. " [ + + ] 

Bridgewater - " The average temperature was 2.3 above normal and precipitation was slightly above normal. The barometer on the second was extremely low. We have had 3 very low barometer readings this year so far. Snow could be seen on the mountains to the west of us on the 24th. No snow occurred in Bridgewater, not even a flake. Precipitation for the year is now 2.52 inches below normal. " - [ + + ] 

Centreville - " The hottest topic for the month of April comes from the two days with a tie for the maximum temperature of 86. This happened on the 6th and the 20th, while nearly in between those two days on the 16th, our monthly low of 33 was recorded. Seventeen days had highs above the average high, while nine days had lows below the average low. This swing to the high side may account for the monthly average of 56.3 being 3.6 warmer than normal. The average nightly low temperature for April stayed in line with the average daily temperature and exceeded the normal average low of 40.2 by 4.3 this month. Two major rain events for April occurred on the 1st and 2nd, and again on the 30th and accounted for 75% of our monthly rain accumulation. For the month, we were over our average of 3.44" by 1.44", or 141% of normal. With our yearly accumulation at the end of April sitting at 14.15", we are running an annual surplus of almost half an inch now. Keep up the good work, men! " - [ + + ]

Maximum rainfall was 2.21 inches and maximum wind gust was 52mph, both of which occurred during the thunderstorm on the 2nd. Rainfall of 2.21 inches on the 2nd set a new daily record. " - [ + + ]

Ruther Glen - Danny emails these notes: " April was another month of spring-like extremes, with the month's minimum and maximum temperatures (32 and 89) occurring within a 72-hour span. Slightly below average precipitation for the month makes for the third month of below average precipitation thus far in 2005. Temperatures finished a half-degree below normal and a full degree lower than April 2004. Strong thunderstorms on April 2 dropped pea sized hail. " - [ - - ]

North Carolina:

Raleigh - " April was a rather uneventful month with the average daily temperature 0.4 below normal and precipitation 1.37 inches below normal. Since January, total precipitation is 3.27 inches below normal. There were only 2 thunderstorm days observed during the month. " - report from Bob [ - - ] 

Raleigh - NWS Raleigh (RAH) reports: " Temperatures during April 2005 fluctuated wildly from week to week, and at times from day to day. Wild temperature swings are typical during the spring across North Carolina. After all of the up and down swings in temperature, temperatures during April averaged very close to the 30 year normal. A storm track that had been active across the southern United States and North Carolina earlier in the year shifted south during April. This was especially true during the mid to latter part of the month as significant rain events became virtually non-existent. The drier than normal pattern that had been confined to southeastern North Carolina in previous months expanded northwest to encompass much of central North Carolina during April. The less active storm track across North Carolina not only brought lower than normal precipitation amounts to much of the state but a minimum of severe weather reports as well. The big severe weather highlight during April was a strong pressure gradient wind event on April 3rd. The strong winds were accompanied by snow showers across the northern Mountains.
