While cold air begins to turn widespread across the East Coast, bringing freezing temperatures as far south as the Southeast, lake-effect snow will continue today across parts of the interior Northeast. This comes as we monitor a significant winter storm for this weekend across portions of the East.

Welcome to the Thursday edition of your Morning Briefing, where we’ll give you a quick rundown on everything you need to know weather-wise, every weekday morning. Let’s begin.

Cold Air Fuels Widespread Lake-Effect Snow:

  1. Cold air behind cold front will keep lake-effect snow around parts of the Northeast this Thursday.
  2. The heaviest of snow can be expected near the lakefronts of Lakes Erie and Ontario, especially this morning.
  3. Lighter and more sporadic snow is forecast across northern parts of New England and in the western Great Lakes region.
  4. The lake-effect snow should begin to dwindle this afternoon and should shut off for the most part by tonight.

Weekend Storm to Bring Heavy Snow to Ohio River Valley, Mid-Atlantic:

  1. A significant winter storm is set to develop later this week, impacting parts of the eastern US through this weekend. Some cities that have not seem much snow so far this season will finally experience several inches of snowfall while others will be out of luck once again.
  2. A disturbance from the Pacific Ocean will develop into a low pressure over the southern Plains Friday, then tracking toward the Mid-Atlantic through this weekend, bringing snow to the north and west of its center.
  3. Moderate to heavy snow will pummel the Ohio River Valley, including the I-70 corridor Friday night through Saturday night. Some locations may receive over a foot of snowfall through Sunday.
  4. The forecast remains uncertain in the Mid-Atlantic and New England, but our current forecast anticipates a moderate snow in the Washington, DC area while freezing rain possible impacts parts of Virginia and North Carolina.
  5. New England will need to monitor for possible snow once the low pressure becomes a coastal storm, but currently little to no snow is forecast. The best risk for any snow at this time will be along the coast.

East Coast to Experience Prolonged Chill:

  1. A cold front associated with a dip in the jet stream is moving across the eastern US, ushering in widespread below average temperatures.
  2. Most of the East Coast can expect temperatures of 5-15+ degrees below average beginning Thursday and lasting through at least early-next week.
  3. Widespread high temperatures will be in the 20s, 30s, and 40s across many cities, with parts of the interior Northeast holding in the single-digits.
  4. Low temperatures this weekend will fall below zero across Upstate New York and northern New England while freezing air reaches parts of the Southeast.
