DC Dryness Continues
March is Second Consecutive Dry Month

Following a record dry February in Washington, 0.5" of precipitation fell the first 2 days of March, but the trend has been downhill from there. With only a week and a half left in the month, the total so far of 0.87" is a little above the record dry March of 1910 (0.57"). For the months of February and March together, however, the total to date of 1.22" is barely half of the record low 2-month total set in 1947. Over 1" of precipitation needs to fall in the next 11 days in order to avoid setting a new record. As of now, the best chance of precipitation appears to be only a 30% chance of showers toward the end of next week.
