000 FXUS64 KMRX 150714 AFDMRX Area Forecast Discussion National Weather Service Morristown TN 314 AM EDT Sun Oct 15 2017 .SHORT TERM...(Today and Tonight)... The passage of a cold front will be the highlight of the period, the first significant frontal passage we have seen in a while. Low level moisture across the pre-frontal environment will mean fog and mostly cloudy skies through much of the day, with perhaps a few scattered to isolated showers into the mid-afternoon. The main band of showers associated with the front, with possibly a few embedded thunderstorms, will enter our Plateau counties in the 21-23Z time frame. The 850-700 mb trough lags the front slightly, so showers will continue overnight but diminish after midnight from west to east as dry air aloft works its way in behind the midlevel trough axis. .LONG TERM...(Monday through Saturday)... After the front moves through we move into a period of quiet and pleasant weather across the forecast area. Temperatures at the start of the week will max out in the 60`s with mostly sunny skies and light winds. Quasi-zonal flow in the upper levels will eventually transition into a ridge of high pressure. This will help keep the skies clear and allow temperatures to warm up throughout the week. By next weekend high temperatures will reach back up into the mid 70`s cross most of the area. No chances for precipitation are expected through the long term portion of the forecast. && .PRELIMINARY POINT TEMPS/POPS...
