Hartford, Connecticut – A late-season cold surge will push overnight temperatures to near or below freezing across Connecticut, raising frost concerns and the risk of slick travel during early morning hours.
According to the National Weather Service Climate Prediction Center, below-normal temperatures will persist across New England through early next week, with Connecticut seeing readings 5 to 15 degrees below seasonal averages. While precipitation remains near normal, the colder air mass increases the chance for winter-like impacts.
Hartford is expected to drop to near 30°F between 2 a.m. and 7 a.m., with colder inland valleys dipping into the upper 20s. Cities including New Haven, Waterbury, and Danbury will see widespread frost potential, especially away from the immediate coastline.
Light precipitation may develop at times, and with temperatures near freezing, a brief mix of rain and wet snow or isolated freezing rain is possible, particularly on untreated surfaces and elevated roadways like I-84 and I-91.
Residents should cover sensitive plants, protect outdoor vegetation, and allow extra time for the morning commute. This colder pattern will persist through early next week, with additional advisories possible as freezing conditions continue.
