YOUR MORNING DISCUSSION
~~~~~~~~~~~~~~~~~~~~~~
Good morning, folks, our Sunday night snowstorm is trending for a bigger hit as the steering mechanisms that guide surface storms (that being big areas of lower and higher pressure 3-4 miles above our heads, a/k/a “troughs” and “ridges” respectively) are trending in such a way as to pull the storm closer to the coast in a more southwest-northeast track south of Cape Cod vs. a “flatter” or more “zonal” west-southwest to east-northeast track, keeping more precip offshore.

I have already raised my snow totals this morning up to a widespread 2-5” accumulation across the greater WMass region.

For now, I believe we should see 2-3” Berkshires / SVT / north of Rt. 2 corridor in MA, VT, and NH, with more like 3-5” south of Rt. 2 corridor from the CT River Valley in WMass and Hartford area east through CMass and northeast CT.

However, if the storm’s northwest track continues to trend closer to the coast, there is a lower chance this could turn into a full on plowable, moderate snowstorm with a 3-6” or a 4-8” accumulation result by Monday morning.

Backing up to today, we have a GORGEOUS mid-January / mid-winter day on tap with high pressure sliding off the New Jersey coast to our south, producing a milder southwesterly flow and highs in the upper 20s to mid 30s or so under partly to mostly sunny skies.

By tonight, southerly winds will be picking up as milder air approaches the region for Saturday and as such, lows will hang in the low 20s under partly cloudy skies.

Saturday will be the mildest day we’ve seen in some time as a secondary warm front passes northeast of our region helping southerly gusts to continue to develop. This set up will push milder air into the region with highs in the upper 30s to mid 40s and gusts strengthening into the 20-35mph range with clouds increasing, and rain showers moving in by mid day to early afternoon.

It will likely hang in the mid to upper 30s in the northwest MA and southern VT, and even in parts of southwest NH, so while I expect cold valley rain showers, we should see some wet snow or mixed rain and snow in higher terrain areas above 1000 feet in the western hilltowns, southern VT and central/northern Berkshires, and a coating to an inch or so is possible there.

Precipitation moves out by dinner time, but some scattered mixed activity may remain, and I also think some upslope snow showers will develop in the Berkshires, Litchfield Hills and southwest VT later Saturday night which could add new coatings of snow, with lows dropping into the 20s.

For Sunday, we start off mostly dry with partly to mostly sunny skies, and it will be cooler behind the front with highs in the mid 20s to mid 30s with cold Arctic air waiting in the wings to be tapped by our developing coastal low pressure system.

Given what I mentioned at the top of the report, the upper level steering players on the field are trending to draw this storm closer, and produce a plowable snowfall across the greater WMass region the way it looks now. Our storm will develop along the mid-Appalachian Range and track northeast towards an area south of Cape Cod and the Islands by Sunday night.

Snow would start sometime between 4-8pm, but I will have to update the onset timing as we get closer. The storm should wind down by early Monday morning, and be most intense / steadiest Sunday night into the early pre-dawn hours of Monday morning, so the commute will be slowed most likely.

It will also be quite cold Sunday night as the Arctic air seeps in, being pulled southeast through our region by the storm passing to our south and southeast. Lows will drop to the single digits to mid teens.

Again, for now, I am calling for a widespread 2-5” of snow, but if the trend continues I could see this becoming a bigger snowstorm, so please stay tuned for updates.

Once the storm clears the region on Monday, the Arctic Hammer truly drops through western MA and adjacent counties with highs in the teens to low 20s, and lows in the low single digits with sunshine returning, and blustery northwest wind gusting to 25mph.

By Tuesday morning, wind chills may be well below zero, with highs only in the single digits and low teens Tuesday and Wednesday with lows below zero!

VERY cold air is coming, and I can’t rule out the potential for another storm by middle of next week, though that one (for now) likely goes out to sea, with milder temps by late week (but still sub-freezing) and another storm shot by next weekend.

I will keep you updated through all of our upcoming wintry changes! Have a great day!
