For The Rest Of Today: An area of high pressure will continue to control our weather the rest of today. This means that it will continue to be cold, but sunny the rest of today. High temperatures this afternoon will be in the upper 20s.
Tonight: Another cold night is expected across Western and Central Mass under partly cloudy skies. Low temperatures tonight will be between 9 and 13 Degrees.
Wednesday: That high pressure system will remain in control of our weather on Wednesday. This means lots of sunshine with high temperatures between 34 and 38 Degrees.
Thursday Through Friday: The quiet weather pattern will continue through Thursday and Friday thanks to that high pressure system.
Thursday will be sunny with high temperatures between 40 and 45 Degrees.
Friday is expected to be partly sunny with high temperatures between 40 and 45 Degrees.
Long-Duration Storm Expected This Weekend: I am beginning to become a little confident about saying that a coastal storm will impact Western and Central Mass this weekend. In fact, it is possible that this storm could linger into Monday.
What is much more uncertain is what type of precipitation may occur (snow, ice, rain or a combination of all of them) and how much.
The players on the weather map this weekend will be (1) A coastal storm that will move near coastal parts of Southern New England from Saturday through Sunday & (2) An area of high pressure over far northern New England and Atlantic Canada that will produce enough cold air to be drawn into this storm.
Some things to point out – First is that the air mass at the beginning of this storm will be relatively mild for this time of year. Normally, this would definitely say to us that this would be an almost all rain event. What may turn this into a wintry mixed mess of precipitation or even all snow for some is that colder air being drawn in from far northern New England and Atlantic Canada. How far south this cold air moves remains to be seen and it will determine who sees mostly all rain, who sees mostly all snow and who sees a mixture of snow, ice and rain.
In addition, this could be a slow moving storm system that could bring a long-duration mixed wintry precipitation event from Saturday through Sunday and possibly into part of Monday.
Given the cold air being drawn in from the north, I think that the areas that have the best chance of seeing enough snow to plow will be across the Worcester Hills and the Berkshires. Elsewhere across Western and Central Mass, I’m currently leaning more towards a messy mixture of snow, sleet, freezing rain and rain for this weekend’s storm.
With that said, these early thoughts about this storm will likely change in the coming days, so stay tuned. It is plausible that we could trend towards a more widespread snow event if more cold air is drawn in than what is currently thought. On the other hand, it is equally as possible that the milder air will win out & this will end up being mostly all rain. Lots of questions that are still unanswered & the uncertainty is still high with this storm.
My Current Thinking Is for a mixture of snow, sleet and rain to move in by midday Saturday.
During Saturday afternoon and Saturday night, I think that we could see mostly all snow in the Worcester Hills and the Berkshires while a mixture of snow, sleet and rain continues elsewhere across Western and Central Mass.
On Sunday, enough cold air may work into the region for everyone to change to some snow throughout the day.
It is possible that some snow across the Worcester Hills and the Berkshires or a snow-rain mix hangs on Sunday night and even into part of Monday.
Keep checking back for the latest updates on this weekend’s storm as I will be posting a new update at least once a day throughout this week.
