Evening Update: Today's totals through 5 pm:
Washington National 0.55"
Washington Dulles 0.77"
Baltimore (BWI) 0.63"
PM Update: Today's totals through 2 pm:
Washington National 0.55"
Washington Dulles 0.58"
Baltimore (BWI) 0.59"
Original post:With a third consecutive day of moderate to heavy showers prompting flood watches and warnings, the Washington DC region continues to add to precipitation totals ranging up to 300% of average over the last 30 days. Thursday's amounts, month-to-date, and year-to-date totals were:
Washington National 0.52"/2.02"/19.29"
Washington Dulles 0.56"/3.25"/23.03"
Baltimore (BWI) 0.63"/1.73"/21.01"
Although the first 5 days of June have gotten off to a roaring start, so far in 2009 the only month to exceed 2008's precipitation total has been January. With another half an inch plus recorded through 1 pm today, this month still has a way to go to reach the 4.8" in June 2008, which was 53% above the average of 3.13".
The rainfall bounty has also not been shared evenly across the broader region. Many outlying areas in Maryland and Virginia are below average for the last 30 days.
