ECMWF models show the cold airmass remaining stationary over the central and eastern U.S. through Wednesday night, meaning overnight freeze conditions will repeat across the East Coast for at least two to three consecutive nights.

❄ Heavy snow accumulation (6–8 in.)	Alaska (Bristol Bay), Iowa, Nebraska	High
🌪 Blowing snow, visibility <½ mile	Alaska coastal areas	High
🚑 Slippery roads, black ice	Iowa, Nebraska, Missouri, Indiana	High
⛄️ Hard freeze overnight (below 28°F)	Virginia, Pennsylvania, NJ, DE	Moderate
🌿 Crop / garden frost damage	All freeze warning states	Moderate
