I dunno about 6 plus in RVA... It's more likely between Ashland to Fredericksburg.
Back to mainly sleet being my area... Exactly why I don't think it will be 6plus here or RVA... (Switching back and forth from sleet & snow)
But if we get a big band /maybe even thunder snow... It can add a few inches quick, if temps drop & stay below freezing without any sleet..
