February 2025 Outlook
February Analogs: 2011, 2008, 2000, 1999,1972
The polar vortex should begin the month very strong, but watch for a potential SSW from about mid month onward.
The pace of moderate storms should increase for the first time all season, just as the warmer weather returns in February, however, a notable difference from many recent months of February is that it should not be prohibitively warm so as to entirely preclude some appreciable snowfall across the majority of the region. The month should finish 1 to 3F above average with near normal to perhaps just below normal snowfall. Northern New England should see above normal snowfall as the cold air source lurks close by in southeastern Canada, which will produce several front-end snowfall for much of southern New England and perhaps even into the northern mid Atlantic at times.

March 2025 Outlook
March Analogs: 2023x2, 2022, 2021, 2017 2014, 2001,1972
The polar vortex should weaken once again to an extent to close out the season, though confidence is not high in a major episode of blocking. The window for a SSW is through about the 20th of the month, so the impact on winter would largely depend on just how early it can take place. During February or at least the first week of March for maximum impact throughout southern New England. There is another window for a potential KU from approximately March 5 through the 19th, but confidence is low.The cold source should be relatively close by at the very least, not unlike February should major blocking not materialize. Near average to 2F above in the mean with near average precipitation inland and slightly below near the coast.
