Twenty-four hours of off-again, on-again drizzle and spit produced barely a third of an inch from Monday into Tuesday. BWI recorded .38 inches of precipitation. That brought the monthly total to 2.56 inches, still .44 inch below normal for this point in the month of May. And most of the rain came in one splash - 2.04 inches on the 19th and 20th.

The good news is that, except for a "slight" chance of showers and thunderstorms on Friday, the long weekend looks fine. Partly cloudy with highs in the 70s.

That will constitute a major warm-up. High temperatures at this time of year SHOULD be in the mid-to-upper 70s. Yesterday's high of 57 degrees was 19 degrees below normal. The day's average of 55 degrees equals the normal low for the date. And it was the third date in May that never rose above the 50s.

So far this month we have had 17 days with temperatures averaging 1 to 13 degrees below normal, and just 7 days that were warmer than normal. Bring on the sun.
