000 FXUS64 KMRX 251902 AFDMRX Area Forecast Discussion National Weather Service Morristown TN 302 PM EDT Tue Apr 25 2017 .SHORT TERM (Tonight and Wednesday)...
-- Changed Discussion --
With high pressure positioned over the Southern Appalachian Region...expect dry conditions and warming temperatures throughout the short term. Recent rainfall combined with clearing skies and light winds...may allow patchy fog to develop late tonight. Only other concern continues to be high river levels. A few area rivers remain in flood and River Flood Warnings are in effect. However...all rivers have crested and river levels will continue to fall through the evening. Wednesday will see above normal temperatures as highs climb into the 80s across most valley locations. .LONG TERM (Tuesday Night through Monday)... An upper level trough and associated surface front will move through the area Thursday, bringing showers and a chance of thunderstorms. High pressure will then build in from the Atlantic through the end of the week, providing very warm temperatures for Fri-Sun, well into the 80s. Surface dewpoints in the 60s will accompany the warm weather, which will prime the pump for the next system that comes through Sunday night and Monday morning, with numerous showers and thunderstorms. This might be a potent system, and given the heavy rain of recent days, saturated soils will help heavy rainfall to quickly runoff into streams and low-lying areas during these two upcoming weather events.
