PM Update: Heavy rain overnight. Sunshine returns tomorrow.

A fast-moving and potent little storm system will move through our region overnight. Evening showers will turn into overnight downpours, with even a stray rumble of thunder or two. About an inch of rain should fall in the 12-hour period between 7 tonight and 7 a.m. Sunday, with most of that total falling in the few hours after midnight. It will all be a distant memory come Sunday, as a progressive weather pattern ensures a quick transition back to high pressure and pleasant springtime weather.

Through tonight: Rain will spread over the area sometime after 7 p.m. Light but steady rain will persist through the rest of this evening before some heavy rain develops overnight. A few rumbles of thunder are possible, as well. Around an inch of rain is expected before the steadiest precipitation moves off to the east just before sunrise. Lows will be in the upper 40s to low 50s, with a northeast wind at about 10 mph.

Tomorrow (Sunday): Showers will linger in the early morning hours, but things will dry out rather quickly, and skies will brighten by the afternoon. Northwest winds will be a bit gusty, at 15 to 20-plus mph. Temperatures will top out around 70 degrees with mostly sunny skies by the late afternoon. It will be clear, calm and a bit chilly Sunday night, with lows in the 30s to low 40s in most spots.
