how cold did it get last night

It’s not possible to say exactly how cold it got last night without knowing the specific city or region being asked about, but across many parts of the U.S. on the night of January 28 into January 29, 2026, temperatures dropped into the 20s °F (‑7 to ‑1 °C) in several areas, with some places seeing readings in the teens or even below zero °F with wind chill.

Typical overnight lows on Jan 28–29, 2026

In the Northeast, the National Weather Service forecast a “dangerous stretch of cold” where overnight lows were expected to fall into the single digits °F (‑13 to ‑18 °C) and possibly below 0 °F (‑18 °C) in spots like the Poconos, with wind chills potentially as low as ‑20 °F (‑29 °C).

In parts of the Mid-Atlantic and Southeast, many areas saw lows in the 20s °F (‑7 to ‑1 °C), with some southern counties staying in the upper 20s °F (‑3 to ‑2 °C). Farther south, cities like Houston saw milder overnight lows, generally in the 40s–50s °F (5–15 °C).

How cold your area got

If the question is about a particular city (like Atlanta, Philadelphia, Baton Rouge, Houston, etc.), the exact low temperature can be checked through:

• Local NWS forecast pages for that city

• Reputable weather sites like AccuWeather, Weather.com, or Weatherspark, which publish daily historical data

• Local TV/radio weather reports from the evening of January 28 into the morning of January 29

On many of these sites, you can look up “January 28, 2026” in the city’s history section and see the official low temperature for that night.

What made it feel extra cold?

Even if the thermometer didn’t hit extreme lows, wind chill made it feel significantly colder in many places, especially across the Northeast and Midwest. Wind chills in the single digits to below zero °F increased the risk of frostbite and hypothermia, and prompted “drip your faucets” warnings in some areas to avoid frozen pipes.

TL;DR

• Across the Northeast/Mid-Atlantic on the night of Jan 28–29, 2026, many areas dropped to the 20s °F, with some locations falling into the teens or single digits °F (‑13 °C and below).

• Exact temps depend on the specific city; for a precise reading, check the local NWS or a trusted weather site for that location on January 28, 2026.

If the location is shared (e.g., “How cold did it get last night in Atlanta?”), that exact low can usually be looked up in a few minutes from official weather archives.
