PM Update: Showers end this evening, and it's much cooler Wednesday.
A freeze watch has been issued for north and west suburbs Wednesday night.
* Freeze watch Wednesday night for western Loudoun, northwestern Montgomery and counties north or west *
Temperatures made the upper 60s and low 70s today despite mostly cloudy conditions. Rain showers that began across the area this afternoon will continue into the evening. They’re out ahead of yet another cold front. It feels as though we’ve had them nonstop this spring. That cold front will bring decidedly cooler weather starting tomorrow.
Through tonight: Showers will tend to wind down within an hour or two of sunset, from west to east. Some rumbles are possible, especially over southern Maryland; generally, we expect the most intense storms to concentrate farther south, closer to Richmond and Virginia’s Northern Neck. After that, it will be partly to mostly clear overnight. Lows should range from about 42 to 49 degrees. Winds will be out of the northwest around 10 mph, with gusts nearer 20 mph or 25 mph.
Tomorrow (Wednesday): We’ll see a mix of sun and clouds, probably sunniest early in the day and some cloud increase over time, thanks to very cold air aloft. Highs should be mainly in the mid-50s to near 60 degrees.
