A violent Arctic plunge is delivering sub-zero wind chills to 100 million Americans and could dust Tallahassee with snow—only the second January in a row Florida has flirted with accumulation.
White-out warnings from Cleveland to Albany
Snow squalls—50-mph micro-bursts of powder—swept across northeastern Ohio Saturday afternoon, cutting visibility below 0.25 miles and glazing I-90 within minutes. The National Weather Service warns the same fast-moving bands will sprint through Pennsylvania and eastern New York overnight, creating instant ice rinks for Super-Divisional playoff traffic.
Sub-zero wind chill map: who gets the worst
- Upper Midwest: –30 °F Sunday night (Duluth, Green Bay)
- Chicago & Detroit: –15 °F to –20 °F
- NYC & Boston: –5 °F to –10 °F by Monday sunrise
- Atlanta: wind chill near 10 °F—cold enough to burst un-insulated sprinkler pipes
Snow totals you can bank on
By 8 a.m. Sunday the Weather Prediction Center expects:
- 3–4 inches across Connecticut, Massachusetts and Rhode Island—first plowable snow of the season for Providence
- 2–3 inches south of Atlanta; black-ice refreeze Sunday night
- Up to 1 inch possible on grassy surfaces in Tallahassee; ground temps hover at 34 °F, so accumulation will melt within hours
Back-to-back Florida snow: how rare is it?
Tallahassee measurable snow events since 1950: 22. Two in consecutive Januarys: zero—until now. Last year’s panhandle blizzard dropped 10 inches near Milton and paralyzed I-10 for two days. Meteorologist Kristian Oliver at NWS Tallahassee calls the repeat “anomalous,” noting average recurrence is 3–5 years.
Why the South keeps getting clipped
A locked-in negative Arctic Oscillation is funneling polar air through the Mississippi Valley. Add a subtropical jet riding over the Gulf and you get lift + moisture + sub-32 °F layers—the same recipe that shocked Houston and New Orleans in 2025. Climate historians point to a warming pole that weakens the polar vortex, making southern excursions more likely.
Travel & power outlook
- Airports: 90-minute delays expected at O’Hare, LaGuardia and Logan Sunday as de-icing pads hit capacity
- Roads: Georgia DOT pre-treats I-75 with brine; Florida’s DOT does not brine ahead of snow because road temps normally stay above freezing
- Grid: ERCOT, PJM and SPP all issued conservative-operations alerts; no rotating outages forecast unless peak load beats the 2024 record
Developer takeaway: cold-weather APIs spike
Requests to NWS’s open API for grid forecasts jumped 340 % week-over-week, according to cloud-monitoring firm AP analysis. Start-ups offering hyper-local pavement-temp models—think RoadFX and CoolRoute—saw venture pings triple. If you’re building logistics software, integrate real-time road-surface temps; traditional air-temp forecasts under-estimate bridge ice by 4–7 °F in the South.
