Below-normal temperatures bringing first frost advisories across Maryland and Virginia

While Tuesday’s cloudy skies will clear in the evening, temperatures will drop from the 50s, reaching lows of 38 to 44 degrees overnight.

The chilly, below-normal temperatures have brought about some of the first frost advisories of the season in the area.

The National Weather Service announced frost advisories for a number of counties across Maryland and Virginia heading into Wednesday morning from 2 a.m. through 9 a.m.

Maryland has frost advisories in Frederick, northwest Montgomery and northwest Howard counties.

Meanwhile, Virginia has frost advisories across Frederick; Rappahannock; Culpeper; northern Fauquier; southern Fauquier; western Loudoun; eastern Loudoun; and northwest Prince William counties.

Frost could harm or even kill sensitive outdoor plants — including vegetables and subtropical plants, such as tomatoes and hibiscus — if they are left outside unprotected.

Plants and vegetation low to the ground can be protected with an extra layer of mulch, while vegetables, crops and other plants should be covered with blankets or row covers, according to the Farmer’s Almanac. Potted plants should be brought indoors.

While Wednesday and Thursday will only reach highs in the low 60s to mid-50s, the area is forecast to warm up once again heading into next week.
