March in Review: Cool and Very Dry
March will go down in the record books as the second cool month of 2009 (joining January), finishing just over a degree below average at Reagan National Airport (DCA). But the dry weather was more notable than the coolness, as rainfall was about 1.6" (or 45%) below the long-term average. Certainly the most memorable weather event was the snowstorm to kick off the month, which dropped 5-8" across the metro region.
Keep reading for the rest of the March climate wrap-up...
Here are some additional climate facts from March:
- Early in the month, temperatures swung from being 20 degrees below average on March 3 (the daily average was 22) to 21 degrees above average on March 8 (the daily average was 65) at DCA. See the earlier posts about this turn of events here and here.
- The highest temperature of the month occurred this past Sunday, when the mercury reached 76 at DCA. The lowest temperature at DCA was 14 on March 3 (the high that day was only 29).
- No high or low temperature records were set at either DCA or Dulles airports. However, a record low of 10 degrees was set at Baltimore-Washington International Airport on March 3.
- After the snowstorm to start the month, we hit a dry spell, with no more than 0.10" in a day between March 3 and March 25 at DCA.
- The combined February-March precipitation total at DCA is the second lowest on record (hat tip Capital Climate).
While March was by-and-large dry, more than an inch of rain fell in the last week of the month, possibly signaling the start of a wet period. The forecast for the next week presents several opportunities for appreciable rainfall. That's a good thing, as the rainfall deficit since October 1 is about 7.3" (5.0" since January 1), and we're officially in drought, as Dan posted last week.
