The season’s first widespread Frost Advisory covers the high country of four states early Friday morning. Four National Weather Service offices issued advisories for the ridges and mountains where they forecast the coolest air.
Temperatures will fall well below where they’ve been in months. That’s enough to bring frost to higher elevations across the Alleghenies and nearby ranges.
The Coolest Morning in Months
The NWS Pittsburgh office covers the higher elevations of Fayette County, Pennsylvania, plus Preston and Tucker counties in West Virginia. Their advisory runs from 1 AM to 8 AM Friday, with lows as cold as 36 degrees.
Ohiopyle, Davis, Thomas, and Canaan Valley are among the communities included. Even areas outside the advisory zone should notice a sharp chill.
Garrett County and the Tri-State Highlands
The NWS Baltimore/Washington office issued two advisories covering the mountain corner where Maryland, Virginia and West Virginia meet. Both run from 1 AM to 9 AM Friday.
Western Garrett County in Maryland, Western Highland County in Virginia, and Western Grant and Western Pendleton counties in West Virginia see lows as cold as 33 degrees. Eastern Garrett County, including Grantsville and Kitzmiller, is under its own advisory for the same cold.
Somerset County, Pennsylvania
The NWS State College office added Somerset County to the list. Lows as cold as 36 degrees are expected there too, from 1 AM to 8 AM Friday.
West Virginia’s High Country: Snowshoe and Harman
The NWS Charleston office covers Northwest Pocahontas and Southeast Randolph counties. Their advisory also runs from 1 AM to 9 AM Friday, with lows near 36 degrees near Snowshoe and Harman.
Protecting Plants Before the Cold Arrives
Cover tender plants before dark tonight. A sheet or frost cloth can trap enough ground heat to make a real difference.
Bring potted plants inside if you can. They lose heat faster than anything planted in the ground.
Harvest any remaining tomatoes, peppers or squash today. They won’t survive a hard frost even under cover.
Check local conditions at weather.gov/pbz, weather.gov/lwx, weather.gov/ctp or weather.gov/rlx before heading out early Friday.
