Low pressure south of New England and an upper level trough will combine to bring the area a chance of snow showers this afternoon and steadier snow tonight. Areas south of Boston, especially the coast of southeast Massachusetts, Cape Cod and the islands have the best opportunity for accumulating snow.
In greater Boston and the western and northern suburbs we may see a few widely scattered flurries or snow showers this afternoon. By this evening a period of steady snow may develop, especially along the coastal plain, and it is possible for an inch or two of accumulation right along the coast. The further inland you go the less chance of any snow activity, especially through the Route 495 belt. Computer models are suggesting that a few narrow heavy bands of snow may set up overnight with this heavier activity staying south of Boston. High temperatures today 35 to 39, lows tonight 22 to 27, coldest inland. Winds will be lighter today, becoming north to northeast less than 10 mph, shifting to northwest tonight 10 to 18 mph.
Friday morning starts off mostly cloudy, even a stray flurry very early, otherwise the trend will be for decreasing clouds through the day. It remains chilly and breezy, with highs 37 to 41 and winds gusting to near 25 mph from the northwest. Skies will average out partly cloudy through Friday night, cold and breezy. Lows falling back to 24 to 28. Winds remain gusty, especially near the coast.
The weekend remains colder than normal, dry and windy at times. Meanwhile, our next potential storm will be moving out of the Rockies and heading east over the weekend to be positioned off the mid-Atlantic coast Monday.
Saturday starts off mostly sunny, clouds building into the afternoon. Highs 40 to 44, with gusty northwest winds to 30 or 35 mph. That wind will bring the wind chills down into the 20s at times. Expect lows to dip to 27 to 31 overnight, under a partly cloudy sky.
Sunday should deliver a bit more sunshine, not as cold or windy. Highs 42 to 46.
Increasing clouds Sunday night with skies becoming cloudy Monday. Depending where the mid-Atlantic storm tracks will impact what our weather is on Monday. A miss to the south and probably a mostly to partly cloudy day. If the storm tracks closer, we could be in for more snow. Stay tuned on that. Low temperatures Sunday night around 30 degrees. Highs Monday about 40.
