It was 52 degrees at 6 a.m. today here at Calvert & Centre streets. We've tacked on another 10 degrees since then, but it was still a crisp slap in the face on the front stoop this morning.

We're in for a high today of just 68 degrees at BWI, according to forecasters out at Sterling. That's about 5 degrees below the long-term average for this date at BWI. The low at BWI this morning was a nippy 39 degrees in the wee hours. That's darn cold for a May 14, and 13 degrees below the average, but still short of the record low for the date - 34 degrees, set in 1996.

And as the high-pressure center that brought all this cool weather - and one glorious Mother's Day weekend - moves offshore, we will come quickly into a return flow of warm, moist air from the southwest tomorrow.

Look for more clouds this afternoon. The forecast high for tomorrow for BWI-Marshall is 85 degrees. Then, at mid-week, we're looking at another cold front from the north and west. That will arrive with clouds and a chance of showers and thunderstorms on Wednesday. And behind the front we can expect another stretch of cool May days with highs in the 60s. Here's the official forecast.

For fans of the International Space Station, we will have a good viewing opportunity - good, that is, if you don't mind getting up before dawn on a Saturday morning - coming up on Saturday the 19th. I will post details on the print Weather Page on Friday morning. (Weather Page comments are accessible at MarylandWeather.com, from a link under the Blog box.)  

The forecast from five days out looks good for the flyover. But forecasters are watching for a low-pressure system that could spin up the coast for the weekend. It's expected to stay well offshore, but ...  Stay tuned.
