Cold overnight Monday will bring a chance of flurries to regions outside of Boston, but for the most part the weather will slowly trend warmer through the week, according to forecasters with the National Weather Service.

Cold temperatures Sunday into Monday will send the mercury into the teens inland from the coast and into the 20s in Boston, Kyle Pederson, a NWS meteorologist told the Herald, and those low temperatures will make Monday morning’s commute a brisk one.

“It’s going to make tomorrow stay a little bit of a chillier day, with highs only reaching 44 in Boston,” Pederson said. “But we’re going to have a slow warm up, it looks like, throughout the rest of the week.”

It will not be as cold as the previous night Monday into Tuesday, though clouds rolling in on a very light breeze bring a slight chance of precipitation — 15% or less, Pederson said — that, when combined with forecasted lows just below freezing, could mean a flurry or two for towns outside of Boston.

Before you break out the sleds and innertubes, Pederson said any snow that does fall will be “very isolated” and will not accumulate.

The sun will come out and it will be dry on Tuesday, according to the weather service, and temperatures will climb into the upper 40s. It should stay clear overnight, but freezing temperatures are possible outside of Boston, where temps will hover in the low 30s, Pederson said.

Mostly sunny skies on Wednesday could send temperatures over 50 degrees through much of the region as the warming trend takes hold. Overnight temperatures Wednesday into Thursday will remain above freezing and in the mid-30s for the most part, though clouds roll in overnight.

The skies clear by Thursday morning, when forecasters predict sunny weather and highs in the upper 50s. Clouds arrive by evening Thursday, and heading into Friday temperatures will dip into the upper 30s.

More clouds are expected to end the work week, when Pederson said another wet weather system could reach the region. Temperatures are expected to break into the lower 60s, and though the wind could be upwards of 15 mph, though according to the weather service rain is not expected until after dark.

Once the sun does go down on Friday, the chance of rain could be upwards of 50%, though Pederson said forecasters aren’t certain of the weather system’s direction yet.

“It’s still a ways out, so there is not really too much detail that we know with that system,” he said.

As of now the weather service is predicting a 50% chance of rain through Saturday and mid-50s temperatures. Sunday could be cooler, in the upper 40s, but potentially dry, NWS forecasts.
