405 FXUS64 KMRX 280756 AFDMRX Area Forecast Discussion National Weather Service Morristown TN 356 AM EDT Tue Mar 28 2017 .SHORT TERM (TODAY AND TONIGHT)...
-- Changed Discussion --
Upper trough is moving across the lower Ohio Valley with the best forcing moving east of the area. Due to continued cold air aloft remaining over the area through early afternoon, we may still see scattered shower development. Models sounding show plenty of boundary layer moisture remaining today, so mostly cloudy sky will be the rule. For tonight, plenty of surface moisture remains allowing fog and low stratus clouds to develop. Some of the fog will likely be locally dense. .Long Term (Wednesday through Monday)...Progressive pattern will continue. By Wednesday, the latest deep H5 trough will be centered over west Texas, resulting in warm ridging and fair weather across our area Wed and Wed night. As the trough lifts northeastward, it will push through the next frontal system Thursday and Thur night, with showers likely and scattered thunder. The core of the trough will pass Friday, keeping precip chances in the area Friday and Fri night. Then fair weather returns thanks to H5 ridging between the departing system and the next southern Rockies/west Texas H5 trough over the weekend. Yes, this means a great Spring weekend is shaping up. Models diverge on the timing of the ejection of that late-period trough, but it will probably bring increasing chances of showers and a few thunderstorms during the early part of the next work week.
