PW values are only around a tenth of an inch but the arctic airmass is taking advantage of any lingering moisture. Snow showers and flurries are more widespread than previously forecast and we have received a tenth of an inch since 7 am at MRX. Expect an additional tenth to a quarter of an inch will be possible across the Northern Valley with an additional half an inch in the foothills and approaching an inch in the highers elevations of E TN and SW VA. With the clouds continuing throughout the day have lowered temperatures by 3 or 4 degrees. Models have really struggled with the snowfall today but do expect things to come to an end this afternoon into this evening with clearing skies. With clearing skies, light winds, and snow cover, expect single digits tonight with a brief dip below zero possible in a few locations.
