Mid Atlantic Precipitation: December Update II

See here for more Washington, DC weather records.

While not as drenching as the previous event, Sunday's precipitation added almost another half an inch to Washington's soggy December totals. The month-to-date amount of 3.47" is now well above the average for an entire December and over 150% of the month-to-date average. Even an average amount through the rest of the month will be enough for the total to finish over 50% above average. The year-to-date amount of 43.58" is also well above the yearly average of 39.35", although it's almost 3" below last year's near-record total.

Here are the daily (Sunday), month-to-date, and year-to-date totals for the Washington-Baltimore region:

Washington National 0.43"/3.47"/43.58"
Washington Dulles   0.58"/3.07"/45.71"
Baltimore (BWI)     0.67"/4.35"/51.86"
