Washington, D.C. – Some residents in western Maryland and the Appalachian Highlands will want to cover their gardens Sunday night, as a rare early June frost advisory takes effect late Sunday through early Monday morning.
According to the National Weather Service Baltimore/Washington office, a Frost Advisory is in place for Garrett County, Maryland, and adjacent higher elevations in West Virginia and western Virginia until 8 a.m. Monday. Overnight lows could drop as low as 35°F in cities like Oakland, Franklin, and Monterey—cold enough to damage sensitive plants.
The cold snap marks an unusual start to meteorological summer, with temperatures dipping into the 30s and low 40s west of the Blue Ridge. Lows will bottom out near 39°F in Franklin, 35°F in Monterey, and 41°F in Romney. In contrast, metro areas like Baltimore and Washington will remain milder, with lows in the upper 40s to low 50s.
Residents in affected areas should bring potted plants indoors and consider using covers for garden beds. Early morning commuters in frost-prone valleys may encounter slick spots on bridges or untreated roads.
The frost threat ends by mid-morning Monday as sunshine and warmer air return. No additional advisories are expected, but a chilly pattern may persist into midweek.
