000 FXUS64 KMRX 041547 AAB AFDMRX Area Forecast Discussion...UPDATED National Weather Service Morristown TN 1047 AM EST Sun Dec 4 2016 .DISCUSSION... An upper-level trough continues progress east across the region this morning, spreading well-needed light to moderate showers across the eastern Tennessee Valley and Southern Appalachians. As this features approaches the region, the pressure gradient will tighten and a 40-50 kt LLJ will rotate over the mountains between 18-00Z. This will result in strong/gusty downsloping winds over the mountains through this evening. A wind advisory will continue for this area and SW NC for winds gusting as high as 40-50 mph. These winds may help to erode the precipitation shield over wildfire areas and maintain or spread the flames in the drier areas. Clouds and low stratus will hang on through the day with highs remaining in the 40s. A chilly and damp day to say the least, but some welcome rainfall with total amounts between 1/2 an inch in the north and up to 2 inches in the south. && .PRELIMINARY POINT TEMPS/POPS...
