000 FXUS64 KMRX 131503 AFDMRX Area Forecast Discussion National Weather Service Morristown TN 1003 AM EST Wed Dec 13 2017 .DISCUSSION... A cold start to the day this morning with most locations dropping down into the upper teens and low 20s with surface high pressure overhead. Temperatures will moderate some today with the surface high pressure shifting to the east and warm air advection returning with southwesterly to westerly flow in the low levels. Dewpoints are currently in the single digits and teens but will begin to creep up throughout the day. Regardless, minimum RH values will drop into the upper 20s and low 30s and will issue a Fire Weather Danger statement for this afternoon. A clipper system to the northwest will create a decent pressure gradient across the area with winds this afternoon in the 10-15 mph range with values high enough for a wind advisory across the mountains. This system will bring a dry cold front through the area again late tonight with another reinforcing shot of colder air. && .PRELIMINARY POINT TEMPS/POPS...
