Good evening everybody, to start off I have attached graphics of all official National Weather Service snow totals.

Before we get going here, I must bring up a few points before people bark at me that these wrong (plus one interesting observation at the end):

1. Look at the times of some of them – some are not final totals. They were the most recent given by that spotter or source.

2. You may be in a town where you got more or less, compared to one of these sources in your same town. It happens. Snow falls in amorphously organic patterns, not town-sized shapes.

3. The nature of the graphical maps is to sort of blend together amounts from one source to another across different locations… this can cause some assumptive errors.

4. Notice how eastern Hampshire/Hampden counties into western Worcester County had that lower amount that I alluded to. What’s interesting is that that is the VERY area in the last storm where it rained in the valley but snowed east that got the jackpot snows, but this time they got the least in WMass/CMass. Mother Nature has a way of balancing things!

Ok, so click away at the graphics and snow totals lists below and have a ball, always fun to see who got what. The most incredible thing that happened was across central NY to central VT into northern Bennington County where basically 3-4 feet of snow fell. So much for a sharp northern cutoff! I never expected the heavy deformation zone/band to expand THAT far northwest, but it did just that. Those folks will be digging out for days. It’s enough that most of us got about 1-2 feet, with some 8-12″ amounts in the areas already mentioned.

MOVING ON
For tonight, a fresh snow pack and slackening north wind will lead to lows in the single digits to low teens as clouds start to break up. Watch for icy areas if you’re out and about.

For tomorrow, high pressure builds into the region and provides mostly sunny skies with highs in the low to mid 20s in the high terrain and mid 20s to near 30º in the Pioneer Valley and points east and south.

INTO THE ICE BOX TOMORROW NIGHT
For tomorrow night, the combination of light wind, clear skies, very dry air, and fresh snow pack will cause us to slip into the freezer. Lows could go below zero in some areas of southern VT and northwest MA, otherwise we will only be in the single digits as radiational cooling maximizes into the pre-dawn hours.

This is quite a Winter blast we got to end astronomical Autumn!!!

High pressure slowly starts to get east of us, but we’ll have one more unseasonably cold day for Saturday with mostly sunny skies and highs in the upper 20s to low 30s with lows in the teens.

For Sunday, a southwest flow develops, which will moderate our temps up into the low to mid 30s for highs and 20s for lows.

Clouds will be building, and some mixed rain and snow showers will be possible as a weak wave moves through the region. Any shower activity will be in the afternoon and evening, and I’m doubtful we’ll see any accumulation but if so, it would be super light, and spotty, but I will update as we get closer.

On Monday, partly sunny skies should do it with highs in the mid to upper 30s, as we start watching an upper level trough swinging into the Ohio Valley with a possible coastal storm developing Monday night into Tuesday.

Could this be another snowstorm or rain/snow mix? It’s possible, but it’s quite uncertain, so it’s just something to watch for now.

This would be a warmer system, and hence wetter if any of it fell as snow, but for now, let’s just watch it.

Seasonably cool temps continue for the rest of next week with highs in the 35-40º range, and there’s also a chance for rain Christmas Eve into Christmas Day with a storm that looks like it will ride inland of us, putting us on the mild side of the storm.

That’s a long way off, so we’ll keep an eye on it.

Thank you so much to all the new followers and to my old, longstanding fans, I appreciate you all so much.

I woke up from my nap to write this, and now I will go have dinner and become a couch potato for a couple of hours before hitting the hay.

Have a wonderful evening, and thank you for all the awesome reports across the region, they help so much in every storm, thank you!
