A second round of wintry weather is expected from the Upper Great Lakes into New England by late Saturday following a round of snow in New England that is beginning to take a break.

Great Lakes, New England, Interior Northeast

As snow winds down in the Rockies, wintry precipitation is getting started in the Great Lakes and interior Northeast.
Up to 0.25 inch of ice accumulation was observed in parts of Upper Michigan Friday morning, including at the National Weather Service outside Marquette, Michigan.
The setup features a low-pressure system strengthening to the east of the Rockies and ejecting toward the Midwest during the weekend.
A stationary front will create a sharp cutoff from cold air to the north and warm air to the south through the weekend, and there should be enough cold air to allow for frozen precipitation.
The position of the stationary front will determine how far south wintry precipitation reaches in the interior Northeast, as it separates chilly 30s and 40s in New England from 50s and 60s in the mid-Atlantic.

Winter Alerts
Saturday Night - Early Next Week
  • A second wave of moisture arrives in the Great Lakes and Northeast, with a wintry mix developing from far northern Wisconsin, Upper Michigan and northern Lower Michigan into upstate New York and New England.
  • Sunday, mixed precipitation should slowly transition to rain in some areas, though colder areas such as the Adirondacks and portions of northern New England may hang on to either snow, sleet or freezing rain.
  • Wintry precipitation could continue through Tuesday or Wednesday in northern New England.
  • Once again, the Interstate 95 corridor from southeastern New Hampshire to the mid-Atlantic looks warm enough for plain rain.

Monday's Forecast
The best chance for accumulating snow appears to be from the Adirondacks into much of northern New England, where a deep snowpack still remains from Winter Storm Stella. Thursday was the 114th-consecutive day with a foot or more of snow on the ground in Caribou, Maine, and they will only add onto that in the days ahead.

Snowfall Potential Through Tuesday
In addition, sleet and freezing rain could lead to some accumulation of ice, which would create very slick conditions on untreated roadways and sidewalks, at least for a time from parts of the northern Great Lakes to upstate New York, western and northern New England.

Storm Recap

As expected, temperatures remained a tad too warm for significant accumulations in downtown Denver, but blowing and drifting snow made travel difficult on the city's south and east sides.
South and southeast of the city, where elevations rise 2,000 feet to the top of the Palmer Divide, blizzard conditions were reported, prompting a shutdown of stretches of Interstates 25 and 70. Up to 9 inches of snow had been measured at Monument Hill, on the Palmer Divide.

Parts of northern New Mexico have picked up a foot of snow or more. An estimated 21 inches of snow had fallen at the Taos Powderhorn SNOTEL station as of Friday morning. Raton Pass - Interstate 25 along the border of Colorado and New Mexico - was closed due to blizzard conditions early Friday.
Winds gusting from 60 to 70 mph were clocked in parts of El Paso County, Colorado, including in Colorado Springs, with some minor damage reported.
