A chilly day in May

Another chilly day for Central Maryland today as the high at BWI stalled  at the 56-degree mark. That is 20 degrees below the normal highs for a May 20 in Baltimore, and just three degrees above the all-time low maximum temperature for a May 20 in Baltimore - 53 degrees, set on this date in 1994.

The high here at Calvert & Centre streets managed to climb all the way to 57 degrees after the sun came out.

Back on May 12 the high at BWI was just 50 degrees, and that did set a record for the date, breaking the 126-year-old record of 51 degrees, set in Baltimore WAY back, on May 12, 1882.

They're calling for a low tonight in the 40s. It's great we haven't had to run the AC yet this year. But we sure did have to throw another blanket on the bed last night. The low at BWI this morning was 44 degrees, just five degrees warmer than the all-time record low for the date - 39 degrees, set in 2002.

So far, we're running almost 2 degrees cooler than normal for the month. Rain is way ahead. We're at 7.52 inches so far through today, making this the second-wettest May on record for Baltimore. The record is 8.71 inches, set in May 1989.  May rainfall has topped 7 inches only three other times:

1894:  7.26 inches

1960:  7.10 inches

1886:  7.07 inches

But warmer, drier days are coming. The new forecast from Sterling says the highs this weekend will stretch into the 70s, and to the 80s in time for Memorial Day. That's - well above the mark predicted in earlier forecasts.
