An area of high pressure will move overhead Monday morning, producing clear skies, light winds, and chilly temperatures.
Lows will be in the 30° to 36° range across northwest and northern Virginia, and a frost advisory is in effect until 9 a.m. Monday. You should cover any tender plants or vegetation.
Lows will drop to near 40° in the Richmond metro area. Lows will be in the mid to upper 30s north & west of Richmond, and some patchy frost is possible.
This will not be record cold, but it will be the coldest overnight low since May, and about 5 to 10 degrees below normal.
Lows Tuesday and Wednesday mornings will be in the 40s, so there will be no threat of widespread frost for much of the area. Colder weather will settle back in for the end of the week, and frost is likely Thursday through Saturday mornings.
The threat for the most widespread frost, including the Richmond metro area, will be Friday and Saturday mornings. During this period, some upper 20s will be possible across northwest Virginia.
