Forecast: Brief Snowstorm Today, But Weekend Will Warm Up

As a storm system passes to our south today, snow will fall, though mostly south of Boston. If Boston were to get a 2 inches of snow, Logan Airport would have a new record for seasonal snowfall.

The heaviest of the snow is going to fall over Martha’s Vineyard and Nantucket. There will also be accumulating snow over the south coast.

After the snow ends, colder air is going to move into the region. This shot of arctic air won’t last very long and already I am seeing some signs of the longest string of above freezing days we have had since December.

Tomorrow is cold, with highs only in the 20s.

Cold, high pressure builds into the area Friday before pushing off the coast this weekend. However, the weekend is looking great, with a trend toward milder air. Highs on Saturday reach the mid-30s and by Sunday it’s going to be in the upper 30s to lower 40s and more melting is going to continue.

A slow melt is exactly what we want to happen over the next couple of weeks. While losing the snow cover is inevitable, we don’t want it to melt too fast.

Next week, more dry air and seasonable to above seasonable air will be firmly entrenched. As highs get into the 40s, the depth of snow will decrease noticeably.

Today: Snow, mostly south of Boston, with a chance of it climbing north, ends by sunset. Highs in the upper 20s to lower 30s.

Tonight: Skies clear and air turns colder with lows 8-15.

Friday: Sunny, with a high in the mid 20s.

Saturday: Mostly sunny, with a high near 35.

Sunday: Mostly sunny, with a high near 40.

Monday: Mostly sunny, with a high near 40.
