RICHMOND, Va. -- An area of high pressure will be overhead Saturday night into Sunday morning.
Clear skies and little to no wind will allow any heat to escape into the atmosphere, causing temperatures to get quite cold.
Low temperatures around daybreak Sunday will be in the upper 30s and lower 40s across the metro. Outlying areas will be even colder, and some frost will be possible. The best chance for seeing frost will be areas well northwest of Richmond, where a frost advisory is in effect. Lows will be in the low to mid 40s near the coast.
The reason why we can get frost when the temperature is a little above freezing has to do with cold air sinking. Thermometers are placed a few feet above the ground. The temperature near the ground is a little colder.
Here is a look at average dates of our first fall frost:
Temperatures will be warmer for the week ahead. Lows Sunday night will be in the 40s. Highs for the week ahead will be in the 70s to around 80. Overnight lows will be in the 50s to around 60.
