Baltimore, MD – The growing season is nearing its end across parts of Maryland and northern Virginia as another round of near freezing temperatures arrives overnight Saturday into Sunday, October 25, threatening sensitive plants and signaling a seasonal shift toward colder weather.
According to the National Weather Service Baltimore/Washington office, frost advisories are in effect from 1 a.m. until 9 a.m. Sunday across portions of central and northern Maryland and northern Virginia.
Forecasters expect temperatures to drop into the lower and middle 30s across many communities, while colder valleys and sheltered locations could fall into the upper 20s.
Growing Season Already Over in Some Areas The National Weather Service reports that the growing season has already ended in locations west of the Blue Ridge Mountains, where colder autumn temperatures have become established.
However, areas farther east remain within their active growing season, making the approaching frost particularly important for gardeners, farmers and residents maintaining outdoor vegetation.
Temperatures could fall near 33 degrees in Cumberland and Hagerstown, 35 degrees around Westminster and 36 degrees near Bel Air.
Across northern Virginia, Winchester could reach 34 degrees, while Luray may fall to approximately 32 degrees.
Sheltered valleys across the Shenandoah Valley, Allegheny Highlands and western Maryland could experience lows in the upper 20s.
What Residents Should Know Before Sunday Frost can damage or kill sensitive vegetation, especially plants that have not yet experienced freezing temperatures this autumn.
Residents in affected areas should consider bringing potted plants indoors, covering vulnerable outdoor vegetation and completing any remaining seasonal harvesting.
While Sunday's cold morning may bring the growing season closer to its conclusion in additional communities, one frost event does not automatically mean the season has officially ended everywhere.
Temperatures are expected to recover into the 60s Sunday afternoon, providing a milder finish to the weekend.
