Frost advisory issued for Friday night into Saturday

If the last few plants from your summer garden are still hanging on, it’s time to bust out the row covers.
That is literally the first piece of advice — “take steps now to protect tender plants” — in the National Weather Service’s preparedness section, for a frost advisory starting late Friday into Saturday morning.
Sub-freezing temperatures down to 30 degrees — and into the 20s in sheltered valleys — is expected throughout Southwestern Pennsylvania and the northern panhandle of West Virginia, according to the advisory.
Friday’s forecast calls for a high in the low 50s with a 30% chance of rain, before the overnight temperature dips to a projected 31 degrees.
And while frost is expected overnight, the advisory expires at 10 a.m.
Saturday’s forecast is sunny and 57 degrees.
The NWS Pittsburgh station recorded a low of 36 degrees on Oct. 6, but that is the closest to freezing the region has come so far this fall.
