000 FXUS64 KMRX 241901 AFDMRX Area Forecast Discussion National Weather Service Morristown TN 301 PM EDT Sun Sep 24 2017 .SHORT TERM (Tonight and Monday)... The closed upper low near the Gulf Coast and the high pressure ridge along the eastern seaboard will retrograde through this period, but there will be virtually no change in the sensible weather across the area compared to today. Above normal temperatures with no precip and light winds will persist through tomorrow. Will lean tomorow`s high temperatures on the warm side of guidance and close to persistence as much of the TN Valley hasn`t seen rain in quite some time. .LONG TERM (Monday Night through Sunday)... Will see little change in area weather through Wednesday with high pressure continuing to dominate. This will keep conditions dry and temperatures warm. Highs are expected to climb well into the 80s across most valley locations both Tuesday and Wednesday. A cold front remains on track to move through the area Thursday/Thursday night. This system looks less impressive with each model run. Moisture appears to be quite limited and the forecast will only have a few northern locations with POPs approaching 20. Dry and cooler air will move in behind the exiting system on Friday but do see some differences in models for the Friday through Sunday time frame. The main questions are... will a secondary surge of cold air move in and will an upper low well to our north be able to affect the Southern Appalachian Region. Current trend is towards a mainly dry period with temperatures generally near to slightly below normal. && .PRELIMINARY POINT TEMPS/POPS...
