The days to come should bring numerous record warm lows, especially by New Year’s Day. In some places, the swing in the “feels like” temperature could approach 100 degrees. But that swift warm-up also means a potential for flooding from melting snow and ice. Temperatures will warm up in the northeast Friday and into the weekend. Locations like Pittsburgh, Philadelphia, Albany and Boston may set or nearly hit records.
Another push of very warm air is likely during the first week of 2023. Abrupt temperature swings, common in La Niña winters, frequently spell serious concerns.
