A fast-moving coastal low born in the Gulf is set to squeeze out snow from the Florida Panhandle to Boston on Sunday—most spots see under an inch, but the cold blast behind it will freeze pipes as far south as Naples.
Why This Snow Band Is Unusual
Southern snow usually needs an Arctic front parked north of I-10 and a Gulf low tracking along it—exactly the setup that has eluded the Southeast all winter. This weekend the atmosphere finally lines up: a 1020 mb high over Pennsylvania funnels 15 °F air into Georgia while a wave of low pressure rides the temperature gradient north from Apalachee Bay.
The result is a 1,500-mile strip where ground temperatures will be within 3 °F of freezing when precipitation arrives—close enough for flakes to survive the 2,000-foot fall to the surface as far south as Tallahassee and Jacksonville

Timeline: When the Flies Fall
- Saturday 10 p.m. EST – Low organizes near Cedar Key, FL; rain breaks out along I-75.
- Sunday 4 a.m. EST – Cold air wraps around the west side; snow mixes in from Dothan, AL to Valdosta, GA.
- Sunday 10 a.m. EST – Coastal low redevelops off Cape Hatteras; changeover reaches Wilmington, NC and Richmond, VA.
- Sunday 4 p.m. EST – Snow shield accelerates up I-95; NYC and Boston see first flakes by dusk.
- Monday 1 a.m. EST – System exits Maine; skies clear, temperatures crash into teens south to Gainesville.
How Much, Where, and Why It Could Still Change
Model consensus keeps totals shy of an inch outside the Appalachians, but a 30-mile westward jog of the low—common with Gulf lows—would plaster Atlanta’s northern suburbs with 2-3 cm and glaze bridges from Birmingham to Augusta. The Weather Channel notes that dew-points in the teens will evaporate the first hour of precipitation, so only heavier bursts can overcome the dry air.
The Real Story: Cold Punch After the Flakes
Regardless of snow, a secondary Arctic front surges south Sunday night, sending freezing line to I-4 in Central Florida. Citrus growers as far south as Polk County will run sprinklers overnight; water pipes from New Orleans to Charleston need wrapping. Monday morning lows: 18 °F in Tallahassee, 28 °F in Tampa, 32 °F in Miami-Dade—coldest since the January 2022 freeze that killed 60% of Florida’s tomato crop.
I-95 Corridor: First Measurable Snow of the Season
New York City enters Sunday 14″ below normal seasonal snowfall; Boston is down 10.4″. A quick 1-3″ with 30 mph wind gusts will snarl post-holiday travel and drop visibility to ¼ mile on the George Washington Bridge and the Mass Pike. Weather Channel data show snow-to-liquid ratios near 12:1 thanks to 20 °F dendritic growth zone, so even modest water yields fluffy accumulations.
Bottom Line
Sunday’s event is classic “conversation snow” for most, but the combo of rare southern flakes and a hard freeze makes it high-impact for agriculture, travelers, and anyone with exposed plumbing. Check forecasts twice—Gulf lows are notorious for last-minute shifts—and keep a winter kit in your car from Jacksonville to Jersey.
