October 30 is the average date for the first freeze in Richmond. We have yet to drop to the magical 32 degree mark, though it was a close call a couple weeks ago when we hit 35.
It will be a close call again on Friday night. We will get a quick blast of cold air.
High pressure will then settle in and provide perfect ingredients for a cold night: clear skies and calm winds.
I'm expecting at least a few areas to drop into the lower 30s with frost likely for almost everyone.
