Tonight will be milder than recent nights, with increasing clouds and temperatures holding mainly in the 50s. While a spotty shower cannot be ruled out overnight, most locations should remain dry. There will be some patchy fog developing overnight. The warm pattern that brought temperatures well above normal this week will linger into the overnight hours before a strengthening storm system begins to influence the area heading into Friday.

Friday is expected to be a wet day, with confidence continuing to increase in a widespread rainfall event. Rain is likely to become more frequent during the morning and continue through much of the day, with periods of moderate to heavy rain possible at times. While exact rainfall totals remain uncertain, forecast guidance suggests some communities could receive 1 to 2 inches of rain, with locally higher amounts possible if the heaviest rain bands develop overhead. Because the region has experienced relatively dry conditions in recent weeks, widespread flooding is not anticipated at this time, but localized street flooding, poor-drainage flooding, and isolated basement flooding could occur where the heaviest rain falls.

Rain should gradually diminish Friday night into early Saturday. The weekend looks considerably quieter, with lingering clouds and perhaps a few leftover showers early Saturday giving way to improving conditions. Sunday is expected to feature cooler temperatures, a mix of sun and clouds, and generally favorable weather for outdoor plans.
