Forecast By SnowBrains Meteorologist – Eric McNamee
12:35 PM MST, Jan. 31, 2021
A strong low is expected to develop today and tomorrow across the northeast, bringing 6-24″ of snow.
This will lead to dangerous travel with near whiteout conditions in spots.
Resorts likely to get the most snow are Killington, Hunter, Okemo, Jay Peak, Mad River Glen, Loon, and Sunday River.
A strong low is expected to develop this weekend across the Northeast, bringing 6-24″ of snow to most of the area.
Snow will start to fill in later today and tomorrow from south to north.
Snow intensity will pick up tomorrow as the low becomes closed and intensifies into a classic Nor’ easter.
Because of this, winds will be quite strong and lead to blizzard conditions in some locations.
This has led to the National Weather Service issuing Winter Storm Warnings to a broad area.
By Tuesday, the heaviest snowfall will be focused on New England as the storm moves off to the north and east.
Getting into Wednesday, snow will be mostly confined to interior parts of New England.
Snow will taper late in the day Wednesday and conditions will clear out temporarily Thursday before another system moves in Friday.
Snowfall amounts have been increased for almost the entire area. Amounts were lowered on the South Fork however. Despite the fact that we are forecasting up to 18 inches of snow, these numbers are conservative if you trust the NAM. The NAM suggests that 2 ft is reasonable for this event where the heaviest band sets up and where it remains mostly snow. Even LI is not out of the woods for getting these max amounts if the GFS/NAM are indeed correct with the temp profiles. Warnings have been issued for all but the Twin Forks, where the watch has been maintained. This is due to the mixing/rain potential. High winds will also impact the area with the storm. The peak will be Mon and Mon eve. Gusts to around 60 mph still seem likely, especially across the ern LI. Blizzard like conditions can be expected with this storm, especially those areas near the coast that remain all snow. An upgrade to a blizzard warning is not out of the question for portions of the area. Those areas most likely to go blizzard would be cstl CT, NYC, and wrn LI. -NWS New York, NY, 1/31/2021
