Eastward shifting of the Madden Julian oscillation from north of Australia to The Dateline over the next 2 weeks is increasingly likely and with intensity which will promote expansion of the warm U.S. pattern eventually including the snowbound Northeast U.S. The Central/East-central U.S. turn wet!

Memory of the winter 2025-26 upper air pattern has featured a semi-permanent polar vortex over the Northeast U.S. Once again, another potent storm within that semi-permanent trough pattern today batters the Northeast U.S. as a blizzard.

Focus is on the Northeast Corridor blizzard, the first widespread blizzard since January 2022. Blizzard Warnings extend from the Mid-Atlantic Coast to east and south portions of New England. The culprit is a coastal storm developing east-southeast of Norfolk, VA early this afternoon drifting slowly northeastward as a “bomb cyclone” with a central pressure near 970 MB south of Nantucket tomorrow at dawn.

Given the low-pressure forecasts, high wind is a major issue with the SUN/MON Northeast Coastal storm. Utilizing the aggressive GFS forecast, wind gusts in the 45-65 mph range should be expected Sunday evening on the Mid-Atlantic Coast extending inland to I-95. By late Monday morning, wind gusts approach hurricane force across southeastern Massachusetts. High wind and heavy snow combination could produce blizzard conditions.
