Pretty crisp out there this morning. Temperatures at BWI-Marshall Airport dropped to 34 degrees overnight, down 52 degrees from Monday's record high of 86. Had to scrape some ice and switch the car heat back on.

The bright April sunshine is nice, but sadly it's going to fade as the day wears on. Look for high clouds to move in as the clear, high pressure moves east and a weak disturbance to our north drags a cold front this way. The northern counties could see a few drops of rain, but mostly we'll get just clouds with highs in the 60s Wednesday and Thursday.

UPDATE, 6 p.m.: Clearly, the cloud cover headed our way has been delayed, due now to arrive overnight. So we snuck in a fine day in spite of the earlier forecast. We deserved it. But the clouds are close. Earlier post resumes:

The clouds will keep overnight lows from dropping below the 40s, so we shouldn't have to scrape windshields again. The cold front (click map to enlarge) is forecast to dip south Thursday, bringing us rain chances Thursday night, increasing to 70 percent by Friday. Those of us who wind up north of the front will get a steadier rain, forecasters said. Those to the south will see a more scattered variety, with a chance for thunderstorms, and milder temperatures.

Groundskeepers at Camden Yards will be watching the skies as they try to squeeze in the Rangers' games.

Rain chances diminish to 30 percent for Saturday and rebound to 40 percent Saturday night. But they don't relent until Sunday. Forecasters predict "mostly cloudy" skies Sunday, with a high near 63 degrees. That looks like the outdoor day this weekend.

Still looking for a break in the weather? Hang on a while longer. Forecasters say disturbances moving along the stalled temperature boundary will mean a persistent 40 percent chance of showers through Monday. Schedule your mental health day for Tuesday which, at least from this distance, looks to be sunny, with a high of 72 degrees.
