March is going out like a lion with a Spring snow storm bringing significant, slushy accumulation to southern Vermont and southern New Hampshire. In the meantime, enjoy a quiet, sunshine-filled Thursday.
High pressure builds south from Canada Thursday, bringing mostly sunny skies and high temps just shy of seasonable averages, upper 30s to low 40s. Light north wind 5-10 mph. Clouds increase from southwest to northeast tonight into early Friday morning, as a low pressure system scoots east of the Ohio River Valley.
Friday morning, as temps bottom out in the mid to upper 20s, light snow spreads north. The morning commute, for the most part, should be fairly quiet. The exception is across southern Vermont and southern New Hampshire, where it may get a little slick thanks to light snow arriving sooner. Throughout the day, that snow inches into central Vermont and the Adirondacks, eventually reaching southern Quebec.
Daytime Friday, snow may mix with rain below 1000′; that includes in the Champlain Valley and St. Lawrence Valley. This, along with the best forcing staying south, will limit snowfall totals in these spots. Temps top out in the mid 30s to near 40 degrees in broad, warmer valleys.
Friday evening, any raindrops switch back over to snowflakes as temps fall to the low 30s. The heaviest snow arrives late Friday evening and overnight into early Saturday morning over southern Vermont and southern New Hampshire. Slushy, wet snow may fall at a rate of 1″ per hour during this period, with loading on tree limbs and power lines possibly causing scattered outages. Saturday, snow will taper off with mountain showers coming to an end by Sunday morning.
The highest snowfall totals will be found over the highest terrain of the Adirondacks (western Essex County, NY) and southern Vermont and southern and central New Hampshire. Here 6-10″ falls with upwards of one foot possible for places like Ripton and Killington. Central Vermont and northern New York (away from the aforementioned valleys) picks up 3-6″. The St. Lawrence Valley, Champlain Valley and Adirondack Coast, and extreme northern Northeast Kingdom picks up 1-3″.
Saturday morning, despite a few snow showers still sticking around, we’ll mostly be in clean-up mode. We are proud sponsors here at Local 22 & Local 44 of the MS Walk: Burlington. Weather-wise, the forecast isn’t anything we can’t handle. Snow totals won’t be all that impressive in the immediate Burlington area and winds remain light. It will be cold and it will be a bit soggy or even slippery. But the biggest issue I see as of now would be snow-covered roads for folks traveling from areas with bigger snow fall totals, and the possibility for dark traffic lights.
Have a great day!
