SUMMARY OF CLIMATOLOGICAL DATA 
MAY 2004

...UNSUALLY WARM MONTH...
...RAINFALL VARIES OVER VIRGINIA
BUT IS GENERALLY BELOW NORMAL OVER THE CAROLINAS...

The big news for May 2004... some of the warmest late spring temps in quite a while across the region- Indeed, look at the high number of bold (in red) station comments in the observers' notes section.

High pressure building off the Southeast US Coast pumped unusally warm and humid air north across our region. The warmth hit sooner while moisture eventually built through the month. Still, most of the stations in the Carolinas recorded below normal rainfall. Use the US Drought Monitor link below to track the progress of drought over portions of South Carolina. Just a day or two ago (6/27/04), S and SW North Carolina were in the abnormally to moderately dry shading; however, as of post time, these areas have been removed. A couple of stations in the Carolinas had excess rainfall totals resulting from springtime thunderstorm activity. In Virginia, many stations were also below normal rainfall; however, there was a greater number of stations with excess rainfall than in the Carolinas, again mostly likely due to thunderstorm activity.

Most everyone reported a rather high number of thunderstorm days.

  • STATIONS MAPS   Ever wonder just where Glen's station in Mechanicsville is located? Or just where is Dave's snowbound station in West Virginia? And, let's see, where is Merriell in Roxboro, NC? An Internet link to MapQuest.com depicting the general area of our region in which you are located is now available with a click to your station ID in the STATION / LOCATION table found at the end of this report. And with MapQuest, you can zoom in and out to get a better idea of where we are all located within the entire region. None of your specific street addresses was used; simply the general area in which you're located is depicted.


  • STATIONS ADDED TO MONTHLY DATABASE   As most all NWS sites have completed their redesign, some sites have added stations within our region to their climate pages. Beginning with this month, we now have reports from WAL, Wallops Island, VA, from EWN, New Bern, NC, from MRH, Beaufort, NC, and from HSE, Cape Hatteras. While we have had very limited data from HSE in the past, we now can access the monthly F-6 from the station via the Newport/Morehead City, NC NWS Office (link below).


  • U.S. DROUGHT MONITOR   While many of us have been blessed with needed rainfall this spring and early summer, some southwestern and southern parts of our region are now labeled in the abnormally to moderately dry intensity areas. For the latest U.S, Drought Monitor graphic, visit http://www.drought.unl.edu/dm/monitor.html.


  • U.S. DAILY WEATHER MAPS PROJECT   Looking for that NOAA Daily Weather Map for a given date since 1871? Look no further! Visit the NOAA Central Library U.S. Daily Weather Maps Project [1871-2001] at http://docs.lib.noaa.gov/rescue/dwm/data_rescue_daily_weather_maps.html. A link to maps for 2002 to the present is found at the top of the page. Great resource! Note: You will need to download and install a small program in order to view the maps.
  • AKQ SPOTTER NEWSLETTER     Bill Sammler, Warning Coordination Meteorologist at NWS AKQ, sends an email note announcing that the latest newsletter is available. Features include a recap of the December 9th, 2003 Central Virginia Earthquake and histories of earthquakes in the area, a review of the summer of 2003 rip currents, and the post Hurricane Isabel early morning tornado outbreak in East Central Virginia. You may download the edition from http:://www.erh.noaa.gov/akq/spotterinfo/spottervol92004.pdf. Within the newsletter, we are informed that basic SKYWARN presentations are now online at http://www.erh.noaa.gov/er/akq/spotterinfo/calendar.htm#Spotter.

Annandale - Lowell sends these notes:" May was very warm and below average in precipitation. May's mean monthly temperature was 70.9 which was the second warmest May here in the last 24 years; only May 1991 was warmer (71.1). This year we had 15 days that the maximum temperature was 85 or above; last year our highest May temperature was only 83. Remember May 2003 was the coolest May on record with the lowest mean monthly temperature on record. May had 16 days of measurable rain and only May 2003 had more in the last 24 years. So it is surprising that May had a deficit of almost one inch (- 0.99) of rainfall. May's average maximum temperature (80.9) was + 5.9 above the average and the minimum temperature (60.9) was +6.8 above the 24-year average. May's highest temperature was 92 on May 23rd which was a +2 departure. The highest minimum temperature in May was 72 on the 23rd which was the highest recorded in May since 1991 and was the third warmest May night in the last 24-years. The other two warmer nights occurred in May 1991. 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 but May made up for the lack of thunder as thunder was recorded on 14 days. The only severe thunderstorm was on the 25th that gave pea size hail for 2-3 minutes. The maximum gust of 28 mph from the WNW on the 3rd at 0032 was the strongest wind gust recorded for May. May set 20 daily records and 17 were for high temperature records. Spring Season: The mean spring temperature was 58.1 which was the highest since 1991 and ranked second place for the warmest in the last 24 years. The total precipitation was 10.63" which was the driest since 2002 and ranked ninth place from being the driest in the last 24 years. There were 20 daily records set! May DAILY Records Tied or Broken- (24-Years of records): 6 daily HIGH maximum temperature records: 10, 12, 15, 22, 23, 24; 1 daily LOW maximum temperature record: 3; 11 daily HIGH minimum temperature records: 10, 11, 12, 14, 15, 16, 21, 22, 23, 24, 25; 1 daily HIGH range temperature record: 9; 1 daily LOW range temperature record: 30.

Arlington - NWS WBC reports: " ...RECORDS... NO RECORDS WERE BROKEN AT WASHINGTON NATIONAL AIRPORT IN MAY. ...SUMMARY... MAY 2004 WAS WARM AND SLIGHTLY WETTER THAN NORMAL IN THE NATION'S CAPITAL. PRECIPITATION TOTALLED NEARLY THREE INCHES...WHICH WAS JUST ABOUT AN INCH BELOW NORMAL WHILE TEMPERATURES AVERAGED ABOUT OVER SIX DEGREES ABOVE NORMAL. THIS MAY WAS THE SECOND WARMEST MAY IN THE 134 YEARS OF WASHINGTON WEATHER RECORDS. WHILE THE NORMAL DAILY HIGH TEMPERATURE IN MAY RISES THROUGH THE 70S...THIS MONTH, TWO-THIRDS OF THE MONTH HAD HIGHS OVER 80...WITH TWO DAYS IN THE 90S. RAIN WAS SPREAD THROUGH THE MONTH WITH MORE THAN HALF OF THE DAYS HAVING MEASURABLE RAIN. "

Bridgewater - " The temperature was 4.1 below normal. Rainfall was 3.28 inches above normal. This was the rainiest May since 1971 and the second rainiest in at least the last 40 years. Precipitation now is 1.38 inches above normal for the year. The first thunderstorm of the year occurred on May 10, but after this, the thunderstorms came popping up just about every day. There were 9 during the month, but most were weak ones. Sharp lightning occurred in only once. My remarks are based on the weather observed here at my location in Bridgewater, Virginia. Places nearby my have had different readings, especially on precipitation. Spotty thunderstorms are responsible for this, and they were spotty during this past month. " - report from Clayton [ - + ] 

Centreville - " While cicada mania seemed to have bugged journalists to the point of insanity and common folk to be just modestly amused, the hot item in May was really the heat. High temperatures equaled or exceeded the daily averages for 24 of the days in May. While we were several degrees away from the record high of 97 set in 1969, our hottest day of 92 on the 23rd helped achieve an overall monthly mean 9.9 above the 62.0 average we were shooting for. Very few cicadas are still around to affirm this, but we had another 92 monthly high on May 23rd, and that happened 40 years ago. There were eleven other years in recent history when temperatures during May were 92 or better. A set of figures that really caused me to get bug-eyed though, was the nightly low average of 62.1 and the statistical overall monthly average temperature of 62.0. It didn't take long to re-focus on the cool facts and report that we logged an average temperature of 12.3 over the 49.8 nightly normal; the greatest difference that I can recall. While it managed to rain at some time during 15 of the days in May, we only accumulated 2.81" of rain for the month, or 63% of our 4.48" normal. Our greatest amount of rain in a single event was 0.76" on May 7th. Hardly enough in slightly over three hours to call significant, but certainly a meaningful contribution to our mounting annual rainfall deficit. For this year, our total rainfall of 12.96" has been 71.4%, or 5.20" short of our 18.16" normal. " - notes from Paul [ + - ] 

Falls Church - " May 2004 was a warmer than average month plus from the middle of the month on was humid as well. There were 3 days 90 degrees or higher. Rainfall was above average and it was a pretty active month for thunderstorms. The worst being Tuesday May 25 around 8pm. I had lots of lightning, thunder and very heavy rain, which brought over an inch of rain in less than an hour. I also had dime sized hail with this storm.
