PM Update: Rain likely tonight, then more gray skies and mild temperatures Thursday.

Much of the region could pick up a several-hour soaking. Rain is mainly out of here by sunrise.

The gloomy days are piling up. Despite the clouds, mild air still won out, with temperatures reaching the mid-50s locally. Although we’ve seen a lot of cloudiness, rain hasn’t been easy to come by. It looks as though we will change that up a bit tonight, potentially with the most rain we’ve seen fall since mid-November.

Through Tonight: Showers are increasingly likely through the evening. Overnight, a steadier rain will develop in the region. It’s hard to pinpoint the maximum zone, but someone could see half an inch or so. I think most of the area will see at least a few tenths of an inch, with some spots more, and the least to the north. Lows will be mainly in the mid- and upper 40s. Winds will be light, from the north-northeast. Patchy fog may develop late.

Tomorrow (Thursday): Overnight rain should end near sunrise. Some fog and drizzle could persist into the morning. I don’t think we will see much rain during the day, but clouds will hold tough. Winds will slowly turn to come from the south as temperatures approach the mid-50s for highs.
