252 FXUS64 KMRX 212019 AFDMRX Area Forecast Discussion National Weather Service Morristown TN 319 PM EST Tue Nov 21 2017 .SHORT TERM...(Tonight and Wednesday)... Upper level trough continues to swing across the area today with an approaching weak frontal boundary. With limited moisture, expecting a mainly dry fropa with just a slight chance for some drizzle/light showers across the higher terrain through the overnight hours. Surface high pressure will build in behind the front, with a dry west-northwest flow aloft. Slightly colder temperatures are expected for tomorrow with highs topping out from the mid 40s to mid 50s. Cloud cover will slowly lift throughout the day Wednesday, with sunshine expect areawide by the afternoon. .LONG TERM...(Wednesday night through Monday)...Quiet weather will be in store for us the rest of the week and through the upcoming weekend. Dry air behind the front will lead to clearer skies and a slow warm up in temperatures the second half of this work week. Secondary front will push through over the weekend and bring in another round of colder temperatures. Right now most models depict that the front will move through dry, but there is a chance for a quick shower as it passes through if we get enough moisture return ahead of the system. After this system passes through we will begin to try and warm up again as we head into next week. $$ && .PRELIMINARY POINT TEMPS/POPS...
