What had looked in the forecasts like a promise of clearing by Saturday, is now looking cloudier, with a persistent but diminishing chance for showers into Saturday night for Baltimore and the rest of Central Maryland. Sunday, at least, still looks pretty sunny and dry, with highs near 70 degrees.

Here's the official forecast.

Blame bad luck, or a stalled cold front to our south and east, or a tropical low near the Bahamas that forecasters expect to move up the coast to a spot off the Delmarva peninsula by Friday evening. They're all conspiring to dim Saturday's outlook. Here's AccuWeather's gloomy take on it. And here's the latest radar loop.

The clouds will also likely spoil what had promised to be a fine view of the International Space Station, which will fly over Baltimore on its way up the coast just before 5 a.m. Saturday morning. There's a chance the clouds will part enough to give us a peek. So, I'm posting details on Friday's print Weather Page, just in case. But I'm not real optimistic.

Yesterday afternoon's rain, meanwhile, left a bit more than a half-inch of rain at BWI. That still leaves us an inch below the long-term average for May thus far. And as cool as it's seemed lately, we're still running 2.6 degrees above normal for the month. The storm had a far bigger impact to our north.
