Winter Storm — Calvert, Maryland

2026-01-25 to 2026-01-26 · Calvert, Maryland

Wider weather episode

An area of Arctic High pressure resided to the north prior to this storm leaving the region in an anomalously cold airmass. To the south, Gulf of America moisture was brought north by a robust southern jet stream. The intersection of these features resulted in a significant amount of wintry precipitation falling across Maryland. This was a Miller B set-up, so warm air was brought north during the event resulting in sleet and freezing rain to mix in. In terms of accumulations, snowfall amounts (which include sleet) averaged 12 to 16 across Garrett County, with a general 8 to 12 across the remainder of the area aside from southern Maryland where 4-8 was observed. If you separate sleet, a general 2 to 5 inches were reported across the state. Freezing rain amounts of a trace to locally a quarter of an inch were observed across southern Maryland. To capture the true magnitude of this event, the actual melted liquid with this storm was near 2 inches across the state.
