Coldest temps of the season knocking on our door. A freeze warning remains in effect for the mountains and foothills until noon today. Some flurries are possible midday for the mountains. Temps elsewhere will struggle to break out of the 50s — 20-25 degrees colder than yesterday. Temps will fall quickly tonight with lows falling into the low to mid-30s. A freeze warning goes into effect from 2am – 9am for all but Lancaster and Chesterfield counties which are under a frost advisory. A breeze out of the northwest will make it feel even colder tonight. Winds begin to die down, tomorrow but expect another cool day with highs in the upper 50s. Overnight lows once again fall near freezing. Expecting more frost Wednesday night as winds calm. Temps start to recover Thursday with highs reaching the low to mid-60s, but some patchy frost still possible Thursday night as lows bottom out in the mid to upper 30s. The weekend will bring on more seasonable temperatures. High pressure will keep us dry with highs reaching the low to mid-70s and lows back into the 40s by Saturday night.

You need calm winds for frost to form. This prevents the atmosphere from mixing, allowing supercooled temps to settle and a thin layer of frost to form.

Even a breeze of 3-5 mph could limit frost development.
This is why Wednesday PM – Thursday AM is the better window for us to see frost.
