SUMMARY OF CLIMATOLOGICAL DATA
... TEMPERATURES SLIGHTLY BELOW NORMAL MOST AREAS ...
... HEAVY RAINS OVER NORTHERN VIRGINIA
BUT DRY CONDITIONS RETURN FOR MUCH OF THE CAROLINAS ...
Just look at those impressive rainfall totals in Virginia's northern reaches! Over 10 inches at Paul Bassett's in Centreville and at Washington National in Arlington. For Lowell's last full month of observing in Annandale (see special note below), he was treated not only to his wettest May, but also to his wettest spring in 28 years!For some stations, this May was the first time monthly temperatures averaged below normal since April of 2007!
ANNANDALE STATION & WEBSITE ENDS 28-YEAR RUN; GLEN ALLEN STATION TO COMMENCE SOON From Lowell Koontz comes some exciting news. He writes: "After 28 years this is the last report from the Annandale Weather Center. The Annandale website weather data will NO LONGER BE UPDATED. This is the result of a move to the Richmond, Virginia area as my son lives there. If all goes as planned the site will become active again by this fall as a Glen Allen, Virginia station. The new site will be called Glen Allen - Springfield Park Weather. Also I think I will be able to keep the same email address as I will be using Verizon DSL in Glen Allen, VA." [Editor's note: I certainly wish Lowell the best and look forward to his new weather station. Having visited his weather central in Annandale, it will be most curious to see how he sets up the Glen Allen site! As he'll be changing from one NWS area of responsibility to another (KLWX to KAKQ), Wakefield has a new tremendous cooperative weather observer in Lowell. I'm sure they've already heard he's coming and can expect his skill, accuracy, and tenacity in weather observation to be a tremendous asset, just as he has marveled so many of us these past 28 years!]
WEATHER LINKS WORTH CHECKING! Kevin Shaw from ACON DC/MD/DE sends these links to check-out:
1. Great site to check out the tracks of all the hurricanes in the Atlantic and Eastern Pacific through time. Please check it out! You won't be disappointed! See what kind of track the Berthas of the past (not just 1996) took and compare it with our current Bertha track! And endless other possibilities! http://maps.csc.noaa.gov/hurricanes/.
2. The Spring 2008 edition of the Sterling Reporter (newsletter of NOAA's Baltimore/Washington National Weather Service Weather Forecast Office) is available at our website: http://www.erh.noaa.gov/lwx/reporter/spring_2008.pdf.
3. Sea Breezes: Thunderstorm Makers or Destroyers? Accuweather's Joe Sobel has an interesting article with a click here.

Virginia:
Annandale - Lowell sends these additional notes: " After 28 years this is the last report from the Annandale Weather Center. The Annandale website weather data will NO LONGER BE UPDATED. This is the result of a move to the Richmond, Va. area as my son lives there. If all goes as planned the site will become active again by this fall as a Glen Allen, VA Station. The new site will be called Glen Allen - Springfield Park Weather. Also I think I will be able to keep the same email address as I will be using Verizon DSL in Glen Allen, VA. May was the wettest May on record in the last 28 years and was below average in temperature. May's lowest maximum temperature was only 50°F on May 12th which was the LOWEST monthly maximum every recorded for May; the previous record was 51°F in 1995, 1996, 2003. The old record low maximum temperature records were set 5-2-1995, 5-7-1996, 5-19-2003. May 12th was a record cold day for May with a daily mean temperature of only 47°F, only May of 1989 was lower by only 0.5°F. The mean temperature for the May was 64.0°F which was a - 0.8°F departure for the month. The May rainfall 9.90 inches, a +5.77 inch departure, and the previous wettest was 1989 when 9.38 inches was recorded. The 3.51 inches of precipitation in a 24-hour period that fell on the 11th and 12th set a new 24-hour record for May. (Records since 1997) The 2.33 inches in a calendar day on the 12th was also the third greatest for the month of May in the past 28 years. May's average temperature range was 24.0°F and was + 3.0°F above the average for the last 28 years and set a new record by 0.4°F. This result may be due to the thermometer no longer aspirating after May 4th in preparation for the upcoming move. The maximum gust of 33 mph from the north on the 21st at 1803 and 33 mph from the NNE on the 22nd at 1043 were the strongest wind gusts recorded for May. The minimum barometer of 29.30 inches on May 12th was the lowest for May since 1984 when 29.28 inches was recorded. The 12th was also the date of the lowest monthly maximum temperature for May. The highest barometric pressure for May was only 30.25 inches on the 28th which was the lowest May monthly maximum since 2001 when 30.16 inches was recorded. Pea size hail recorded in the thunderstorm of May 31st. There were 10 daily records set! May DAILY Records Tied or Broken- (28-Years of records): 1 LOW maximum temperature: 12; 5 HIGH range temperature: 7, 25, 26, 29, 30; 4 HIGH precipitation: 9, 11, 12, 31. SPRING SEASON: The mean spring temperature was 56.4°F which ranked ninth place from being the coolest in the last 28 years. The total precipitation was 19.61 inches which was the wettest spring in the past 28 years. The previous record was 1983 with 19.19 inches.

Bridgewater - " The rainfall for the month was about normal while the temperature was slightly below normal. The rains for most of the spring have come in big bunches with rather dry spells in between. It has not been a good growing season. It has been rather cold for this time of the year. In a more informal look at the month, Clayton adds, "Many places got more rain that we got. It seems storms formed east of the mountains. My garden looks terrible. It's either too wet, too dry, or too cold. A lot of the things didn't come up!" " - [ - -/+ ] - notes from Clayton
Centreville - Paul sends these notes: " As the shortest month of the year, May was certainly long on making weather news. With the average monthly temperature slightly below normal and the precipitation significantly above the monthly average, May certainly has earned my tip if the hat. Only seven days had maximum temperature readings in the 80's with the 31st registering the warmest of the month with 85°. May logged 72.1° the monthly average high temperature; 2.2° below the 74.3° average high. The overall monthly average came in at 61.5° 0.5° below the 62.0° norm. Nighttime lows even presented an unusual surprise. Record books depict the average monthly low for May to come in at 49.8°. This month that temperature worked out to be 50.9°; just 1.1° above what we would expect. This is the smallest deviation since February 2007; 15 months ago. For those with snow blowers, it's probably not too early to begin winterizing. The near typical temperatures were accompanied by less than typical rainfall for this mecca of fun lovers. With 11 days of recordable moisture, a grand total of 10.55" fell into the log books. This is 236%, or 6.07" over our 4.48" normal rainfall amount. Boat building books began to become scarce as the month progressed; particularly on the 11th and 12th when 4.50" fell in 24 hours. This was 35% of our monthly accumulation that accompanied five consecutive days of precipitation when 7.17" caused some minor street flooding for a short period. For the year we now enter June with a surplus of 6.16"; 13.18" over the same time as last year. Ah, neighborhood rafting at its best. " - [ - + ] - notes from Paul
Chantilly - Russ Topping reports: " May was certainly an eventful month weather month. We went from the driest May in 2007 to one of our wettest ever in 2008. The big news for May was the 7.5" of rain that fell between the 5-day period of May 8th thru May 12th. Flash flood warnings become common. Daily precipitation records were broken on the 8th (1.14") and 11th (3.89"). Many commented that this was the worst rain event since Agnes. The total for the month was 8.79". What a change from May 2007, which at 0.34" was our driest ever. Our record wettest May still stands at 10.26", which occurred in 1988. The average temperature was 1.3° below normal, with a record low daily max of only 48.6° on the 12th. A record high minimum daily temperature of 69° on the 27th tied the old record. Thunderstorms rumbled through on the 7th, 8th and 31st. Dense fog was observed on the 31st. *Please note, anemometer is currently partially obstructed from the southeast " - [ - +]
