531 FXUS64 KMRX 200530 AFDMRX AREA FORECAST DISCUSSION National Weather Service Morristown TN 130 AM EDT Sun Mar 20 2022 .UPDATE... FOR 06Z AVIATION. && .DISCUSSION... Satellite imagery shows clouds are beginning to thin out or dissipate from the southwest late this evening. Still have quite a bit of clouds to move through however, and even have some spotty light showers on radar. This should all continue to clear up overnight though, with places in southwest Virginia and the Tri Cities area likely seeing clouds until almost daybreak tomorrow morning. Overnight lows will be tricky tonight. Dewpoints remain in the mid to upper 30s, even in places near Huntsville where the surface high is centered and winds have gone calm. Calm winds and clearing skies would favor lowering overnight temps. But all guidance favors mid 30s on the low end tonight. Between cloud cover, winds, and these dewpoints, this seems reasonable so kept that part of the forecast unchanged. CD && .AVIATION... 06Z TAF DISCUSSION. VFR conditions forecast to prevail.
