Reinforcing blast of chilly air to hit northeastern US early this week

Topic driven playlist

Following a blustery and chilly weekend, temperatures will once again take a tumble across the northeastern United States during the first half of the week.

The first sweep of chilly air moved across the region on Friday and Saturday, with gusty winds, soaking rain and high-elevation snow.

A general 1 to 3 inches of snow fell across the Adirondacks, Berkshires and Catskills on Saturday. Even higher amounts fell across the tallest peaks.

From Monday to Wednesday, an even cooler air mass will sweep across the region as a cold front dives southward.

Prior to the chilly blast, temperatures will rise to near to slightly above normal on Sunday.

"A chilly high pressure system will build across the Great Lakes, eastern Ohio Valley into the Northeast," according to AccuWeather Long-Range Meteorologist Paul Pastelok.

Highs in the upper 30s to middle 40s F will be common across New York and New England, with highs generally in the upper 40s to upper 50s in the mid-Atlantic.

The coolest air will arrive on Tuesday and Wednesday, when highs will range between 5 and 10 degrees Fahrenheit below normal.

Lows will drop into the 20s across much of New York and New England, with 30s expected elsewhere across the region.

"Some areas untouched by frost so far this season in the mid-Atlantic could be reached during the middle part of the week," according to AccuWeather Senior Meteorologist Alex Sosnowski.

Those who have not had to turn on the heat thus far may have to do so this week.

The cool push will be accompanied by blustery conditions which could knock down and blow around unsecured harvest and Halloween decorations.

Factoring in the wind, AccuWeather RealFeel® Temperatures are expected to be 5 to 10 degrees lower than the actual temperature, despite some sunshine.

Sun may be limited across portions of upstate New York and northern New England, where rain showers may mix with wet snow from Tuesday into Wednesday morning.

Snow accumulations will generally amount to a coating to 2 inches, with higher amounts across the mountain peaks.

Beyond midweek, there may be a brief warmup before another shot of cold air arrives in the Great Lakes and Northeast during the first few days of November, Pastelok said.
