Boston weather: Trending cooler with a chance of rain and snow this weekend (Photos)

Last nights rain is long gone and the last of the storm clouds pushed offshore around sunrise this morning. With high pressure returning we are set up for one more day of mild temperatures as we have a blend of sun and clouds today. The high temperatures should reach the upper 40s to 50 degrees this afternoon. Winds will be west to northwest at 10 to 18 mph.

Tonight, an upper level disturbance pushes east and will be overhead into Thursday. This will bring us more clouds and just an outside chance of a flurry later tonight and early Thursday, with a few drops of rain mixed in during the afternoon. Although there is that slight chance of precipitation most of Thursday should remain dry. It will be cooler, by some 10 degrees, from today’s readings and a bit breezy as winds kick up from the northwest and may gust to 25 mph. Expect lows tonight between 25 and 30 degrees, coolest away from the shore. Highs on Thursday near 40 degrees.

Thursday night a reinforcing shot of colder air will come down over the region behind the departing upper level trough. Temperatures will fall to near 20 inland and the mid 20s on the shore. Gusty northwest winds will continue, making for a rather cold night for mid-March.

Friday, another breezy and chilly day as the mercury only climbs to 35 to 40 degrees, which is several degrees below normal. And, with continued northwest breezes that may get feisty at times we will feel the chill all day long. Early sunshine gives way to partly cloudy afternoon skies.

The weekend is shaping up to be 50/50. A weak low pressure system will influence our weather on Saturday, with high pressure returning Sunday. Clouds increase overnight Friday and Saturday will be a cloudy day with a chance of light rain and or snow. The emphasis is on light. The low is forecast to track south of New England but is not expected to intensify and become a major player in our weather. Although far interior sections, along and west of Route 495, could see a light accumulation the better option is for wet surfaces only. The system should be out of here early Saturday night as skies begin to partially clear. Highs on Saturday upper 30s to 40 degrees, with lows falling back into the 20s overnight.

Sunday looks nice for Saint Patrick’s Day as sunshine returns and temperatures rebound to near 40 degrees.

Looking further out there is concern for a potential significant storm early next week. This will be monitored closely over the next several days to see if we will in fact be impacted by this system.
