555 FXUS64 KMRX 171445 AFDMRX Area Forecast Discussion National Weather Service Morristown TN 945 AM EST Sun Dec 17 2017 .DISCUSSION... Starting to see a few reports of precipitation making it to the ground across the forecast area. Temperatures are below freezing in a few locations and there have been a few reports of sleet mixing in with the rain. With the strong warm air advection just above the surface, expect precipitation will quickly change to all rain and do not anticipate any impacts from the brief wintry mix at the onset. Speed up and increased PoPs some based on the latest radar and hi-res model trends. The 12z sounding from OHX indicates a significant dry layer below 750mb and any precipitation that makes it to the surface will be light. Overall,rainfall amounts will be under a tenth of an inch for most locations. Temperatures will struggle today under cloudy skies with highs generally in the mid 40s. && .PRELIMINARY POINT TEMPS/POPS...
