SUMMARY OF CLIMATOLOGICAL DATA 


MARCH 2010

... WARM-UP CHASES AWAY WINTER SNOWS & WOES!...

 
  • EXTENSIVE LISTING OF WEATHER & CLIIMATE RESOURCES  Kevin Shaw of ACON MD/DE/DC sends this list of what appears to be quite an exhaustive listing of websites compiled by the NOAA Library staff on weather and climate. He's not quite sure to what extent it is up-to-date, but interesting and potentially a useful research tool nonetheles! http://www.lib.noaa.gov/researchtools/subjectguides/weathersites.html


  • THE EASTERN US WEATHER CONFERENCE The 6th annual Eastern US Weather conference is rapidly approaching! You don't have to be a member to attend the conference. BWI Airport Marriott is the location & June 11-12 are the dates. Check out the agenda, the conference speakers, online registration, hotel accomodations if you want to stay overnight, and much more at the conference website: http://conference.easternuswx.com/


  • NOAA'S STORM PREDICTION CENTER (SPC) It's that time of year again when many of you may experience severe weather. NOAA's Storm Prediction Center (SPC) monitors potential severe weather situations across the country and helps to give both the citizens and forecasters in your area a heads-up of the potential of hazardous weather situations. The Storm Prediction Center's mission is to provide timely and accurate forecasts and watches for severe thunderstorms and tornadoes over the contiguous United States. The SPC also monitors heavy rain, heavy snow, and fire weather events across the U.S. and issues specific products for those hazards. To learn more about the Storm Prediction Center click here: http://www.spc.noaa.gov/


  • DROUGHT MONITOR    http://www.drought.unl.edu/dm/monitor.html    More information on drought can be found at NOAA's Drought Information Center http://www.drought.noaa.gov/


  • REMINDER All National Weather Service station data listed herein is preliminary and may be subject to change.  The data has not been certified and cannot be used in legal actions.  Only reports certified by the National Climatic Data Center in Asheville, NC can be used for these purposes.

    Glen Allen - Lowell Koontz adds: " March was warmer than average as the monthly mean temperature was 50.8, a 4.1 departure, and was also much wetter than average (when compared to Ashland, Virginia records). The 5.72 inches of rain for March was a +1.97 inch departure when compared to the Ashland, VA average. The maximum rainfall recorded in a day was 1.38 inches on the 28th. The total snowfall was only 0.4 inches for the month recorded on the 2nd which was a -1.3 inch departure compared to Ashland, Virginia records. March this year was both warmer and wetter and far less snowfall than March of last year. There were 9 days the minimum temperature dropped below freezing. The maximum temperature for March was 78 on the 20th; last year it was 83. The lowest minimum was 24 recorded here on the 7th; last year the minimum temperature was 7 and a record low for March. Very low relative humidity on the 7th and 8th of 14% here and the Richmond International Airport on the 8th at 1400 had 9% relative humidity and a dew point of 4 F which is the lowest I have ever seen. I haven't been able to find the record low relative humidity for the Richmond International Airport and would appreciate hearing from anyone who has this information!! The maximum wind gust of 44 mph occurred on the 28th at 2028 hours and was the highest wind gust recorded here since records were started in August of 2008. The lowest barometric pressure was 29.29 inches on the 13th the lowest since April 3, 2009 when the pressure was 29.24 inches. January's minimum pressure was nearly as low at 29.30 inches on the 25th when we had a 41 mph gust. The highest barometer recorded for the month was 30.37 inches on the 27th which was less than normal. " - [ + + ] 

    Herndon - Randy adds: " Spring arrived. March was above normal for temperature and near normal for precipitation. The temperatures ranged between a high of 76 and a low of 27. The average high and low were about 3 degrees above normal, respectively, which was very welcome following several months of below normal temperatures. On the precipitation side, the month was 0.05 below normal with 3.66" measured. We only had one snow event occurring on the 2nd when we received 0.1" before the precipitation turned to rain. Other than the light precipitation we received on the 2-3rd, the rain occurred in two periods: the first from the 12-15th when we received 1.75" and the second was a rainy period from the 21st thru 30th when we received another 1.80". We have now had 9.94" precipitation for the year which is just slightly above normal. The total snowfall for the season is now 80.4" which, as mentioned last month, is an all-time record. " - [ + - ]

    Ladysmith - Danny reports: " March made memories of winter fade very quickly! Four days with thunderstorms, lots and lots of rain, and above normal temperatures characterized the month. " - [ + + ]
