With sunny skies, expect a high around 34 today, with a northwest wind at 10-20 mph, with gusts up to 50 mph possible. A wind advisory is in effect for the day today, but winds subside tonight, giving way to a clear and cold night with a low around 15, and a northwest wind at around 5 mph at the most.
Tomorrow will feature increasing clouds, with a low around 32, and a light northwest wind, leading into our first accumulating snow of the year for Thursday night.
Snow will start in the evening, continuing overnight, before turning to a mix of snow and sleet late in the night. The low will be 28, and expect 2 to 4 inches of snow accumulation with an east wind around 5 mph. The mix of snow and sleet will continue through mid-morning before changing to plain rain. A brief period of freezing rain can’t be ruled out during the transition as well. In any situation, the Friday morning commute is going to be a complete mess, and I’d expect school delays to take place on Friday morning.
There is some uncertainty on snowfall amounts; there is a possibility for an earlier or later transition to a mix with sleet, and even an outside chance we go directly from snow to rain (though this last one is unlikely). A later transition to sleet, which is realistically possible, would give us a little more snow, while an earlier transition would notably cut back on amounts. Below is my current forecast map; a general 2-4″ for most of southern New Hampshire and interior Massachusetts, with 4-6″ in the northern Worcester hills and the Monadnocks where snow will hang on longer, and 1-2″ near the coast.
Once the morning mess clears up, a cold rain continues into midday Friday before ending in the early to mid afternoon, with a high around 38. The weekend will be sunny and cold, with morning lows of 28 for Saturday and 26 for Sunday, and highs of 42 for Saturday and 37 for Sunday.
Have a great day!
