For The Rest Of This Afternoon: An area of high pressure will continue to control the weather throughout the rest of this afternoon.
This means that lots of sunshine can be expected throughout the rest of this afternoon. Temperatures will be near 35 Degrees. Winds will be Northwest at 5 to 10 mph.
Tonight: Skies will start out clear this evening, but will become partly cloudy during the after midnight hours. Low temperatures will be between 20 and 25 Degrees. Winds will be Southwest at 8 to 16 mph.
Saturday: A cold front is expected to move through the area during the afternoon hours on Saturday.
Skies throughout the day on Saturday will be cloudy. In addition, widespread rain showers are expected to overspread the entire area by mid-afternoon and then continue through the late afternoon hours.
High temperatures will be near 45 Degrees. Winds will be South to Southwest at 10 to 20 mph.
Saturday Night: That cold front will push to the east during the evening with a drier northwesterly wind flow taking over by after midnight.
Any leftover rain showers will end during the early evening hours with some breaks in the clouds possible during the after midnight hours. Low temperatures will be between 30 and 35 Degrees. Winds will be Southwest at 10 to 20 mph before midnight and West to Northwest at 5 to 10 mph after midnight.
Plowable Amounts Of Snow Are Likely From Sunday Afternoon Through Sunday Night Across All Of Western & Central Mass: It is looking likely now that a plowable amount of snow will occur beginning on Sunday afternoon and continuing through Sunday night across the entire area. That said, there is uncertainty as to how close the low pressure system moving along a frontal boundary will track to our area.
The “goal posts” for the track of this storm seem to be from a storm that moves across eastern and southeastern Mass, which would lead to the most snow occurring across the northern Worcester Hills as well as across the middle and upper Pioneer Valley of Western Mass and the Berkshires to a storm that tracks well south and east of Nantucket, which would lead to most of the snow occurring over eastern and southeastern parts of Worcester County and much less as you head into Western Mass.
At this point, my thinking is for a storm that tracks near Nantucket during Sunday night before heading towards Nova Scotia by Monday morning.
My Current Forecast Based On My Analysis Is For rain or a rain-snow mix to begin across the entire area by early Sunday afternoon. Any rain to start with is expected to be quite brief and the rain or rain-snow mix will change to all snow by mid-afternoon. One area that the rain might hang on a little longer is across far eastern and across southeastern parts of Worcester County (I-495 and Route 146 corridors) where the colder air might take a little longer to move in. Even here though, the rain will change to all snow by about late Sunday afternoon.
The snow is then expected to continue throughout the night on Sunday night. In addition, the snow may be moderate to heavy in intensity at times, especially during the first half of Sunday night.
I also think that we’re probably going to see crashing temperatures during Sunday evening as some Arctic air pushes into the region. This means that wet surfaces from the initial rain or rain-snow mix will flash freeze leading to the development of very icy conditions during Sunday evening. These very icy conditions will combine with the snow accumulating on top of the ice to lead to some extremely slick conditions throughout Sunday night.
The snow is expected to come to an end just before sunrise Monday morning.
My snowfall forecast for this storm can be found with the map attached to this post. Again, be aware that the snow will be accumulating on top of some very icy ground conditions leading to some potentially extremely slick travel and walking conditions throughout all of Sunday night. These very icy conditions will likely persist through much of Monday.
Temperatures on Sunday will reach 35 to 40 Degrees during the early afternoon hours. Temperatures will then crash to the 25 to 30 Degrees by early Sunday evening and then continue to drop to near 20 Degrees by midnight reaching 10 to 15 Degrees by sunrise Monday morning.
Winds on Sunday will be North at 7 to 14 mph. Winds on Sunday night will be North to Northwest at 10 to 20 mph with gusts to 30 mph.
I will continue to keep very close tabs on this storm and will have many more updates as needed over the next couple of days or so.
The Coldest Temperatures Since Early February Of 2023 Are Expected During The First Half Of Next Week: The big weather story for much of next week will be the Arctic outbreak leading to the coldest temperatures since early February of 2023.
Monday will be partly sunny, very cold and windy with high temperatures between 15 and 20 Degrees. A North to northwest wind of 15 to 25 mph will produce wind chill temperatures of around zero throughout the day.
Monday night looks clear, very cold and windy with low temperatures near zero. Wind chill temperatures of minus 10 to minus 20 can be expected.
Tuesday is expected to be partly sunny, very cold and windy with high temperatures near 15 Degrees. Wind chill temperatures of zero to minus 10 can be expected throughout the day.
Tuesday night will be partly cloudy and very cold. Low temperatures will be near Zero.
Wednesday looks to be another very cold day under sunny skies. High temperatures will be between 15 and 20 Degrees.
