Simulated Radar Next 18-hours into Saturday Noon ET

Northeast storm system quickly moves off the coast taking its snow and sleet with it — but could still see some flurries or light snow showers in the morning

West Coast finally calms down with high pressure shutting off the Pacific moisture flow No complaints about the heavy snowfall in the Rockies even with “above normal” temperatures — it’s still snowing heavily at ski resorts that desperately need it.

Headlines Friday Evening

• Winter storm warnings across the Northeast with a “snow emergency” up in New York City — with heavy snowfall and sleet blanketing roadways.

• Powerful “bomb cyclone” blizzard now scheduled for Sunday/Monday across the Great Lakes with central pressure around 971 mb —> gusty winds > 60 mph possible in Michigan. Yikes!

• Much colder air behind a cold front attached to this cyclone — which then tracks into Hudson Bay into mid-week becoming vertically stacked with a lobe of the Polar Vortex —> winter cold returns to the Eastern U.S. into next week

HRRR Simulated Radar Next 48-hours to Sunday 1 PM ET

We see the formation of the storm system in the Great Lakes — impressive banding underway into Sunday afternoon.
