Good morning everybody, I think thankfully for everyone involved, we’ve got an upcoming break in our active late-winter pattern as most of us wake up to probably the thickest most widespread snow pack this season (which isn’t saying much, I know).
Most interestingly, we have a couple of deep lows in the North Atlantic, one hundreds of miles east of New England, and one over Newfoundland (the southeast part of it where St. John’s is located), and these two areas of low pressure are producing a block in the atmosphere.
This means that, more or less, we’re going to be under the influence of a large gyre, or low pressure circulation, situated on its southwest flank, which will push northwest flow through our region all week long.
Today will likely feature more clouds than sunshine, especially earlier in the day, with highs in the mid 30s to low 40s, and we can’t rule out an isolated shower.
By tonight, high pressure will push east into our region and press up against that blocked low pressure east and northeast of us.
This will increase the pressure gradient and cause northwest winds to pick up and gust 25-35mph at times overnight with lows in the mid 20s, lasting into tomorrow with mostly sunny skies (the pick of the week!) with highs in the upper 30s to mid 40s.
By Monday night, we’ll cloud up as a moisture-starved system in that northwest flow set up will be diving southeast out of Ontario and through the eastern Great Lakes, passing into the Atlantic Ocean somewhere near the NYC metro.
This keeps the system to our south, and with a nighttime passage and lows in the low to mid 20s, at least part of our region will see snow showers break out after midnight, especially in the central/southern Berkshires, western Hampshire/Hampden hilltowns into the Springfield metro, and down in northwest/central CT including the southern Taconics of NY.
This could put down a wet snow coating to an inch or two before sweeping out of here Tuesday mornin, and we can’t rule out some minor Tuesday morning commute impacts, especially in Litchfield and Hartford Counties CT.
Any snow or rain showers end by noon Tuesday with highs in the upper 20s to mid 30s, and Tuesday night will be dry, cold and windy behind that little low with lows in the upper teens to mid 20s for a blustery evening.
The departure of that wave ushers in a persistent northwest flow pattern Wednesday into the weekend with highs in the 30s to low 40s each day and lows in the 20s at night with varying periods of sun and clouds, but mostly dry conditions as that block stays in place.
By Saturday night into Sunday, there are some storm signals for a potential wintry coastal storm, but it’s a long way off and not something to be concerned about at the moment.
Have a great Sunday, and please remember that if you appreciate or depend on my work, I rely on your support to keep me here 365 days a year for every storm or event that hits our region.
