Boston is starting Wednesday under mostly cloudy skies and patchy fog, but the gray opening act should give way to mostly sunny conditions and a high near 86 degrees. Southwest winds will stay light at 3 to 9 mph, making for a warm afternoon across the city. Tonight will be mostly clear, with temperatures dipping to around 69.

Sunny Wednesday Gives Way To Thursday Showers

The National Weather Service Boston/Norton says the patchy fog should fade shortly after sunrise, with dry weather holding through Wednesday night. Thursday brings a noticeable shift, with a chance of rain showers after 10 a.m. and a high near 84 degrees. The chance of precipitation is about 50%, though rainfall totals are expected to stay below a tenth of an inch.

Friday Brings A Brief Break

After Thursday's unsettled weather, Friday looks like the week's calmer reset, with mostly sunny skies and a high near 78 degrees. Northeast winds of 6 to 10 mph could make the day feel cooler, especially near the water. Friday night should be partly cloudy, with a low around 64.

Showers Could Hang Around This Weekend

Another round of unsettled weather is possible Saturday and Sunday, when each day carries about a 40% chance of rain showers. Saturday should reach around 75 degrees, while Sunday tops out near 76 under mostly cloudy skies. Thunderstorms are not the main story, but they remain a possibility if daytime heating lines up with the incoming weather system.

Monday and Tuesday currently look brighter and somewhat cooler, with mostly sunny skies and highs near 79 and 77 degrees, respectively. No weather watches, warnings, or advisories are in effect for Boston in the current forecast.
