000 FXUS64 KMRX 291419 AAB AFDMRX AREA FORECAST DISCUSSION...UPDATED NATIONAL WEATHER SERVICE MORRISTOWN TN 1019 AM EDT MON SEP 29 2014 .DISCUSSION... A BROAD UPPER-TROUGH IS SWEEPING THROUGH THE REGION THIS MORNING...AND WILL USHER OUT THE LAST OF THE ISOLATED TO SCATTERED LIGHT SHOWERS ALONG THE FOOTHILLS AND MOUNTAINS BY EARLY THIS AFTERNOON. IN ITS WAKE...DRIER AIR IS QUICKLY MOVING INTO THE REGION...ALLOWING FOR SOME PARTIAL CLEARING AND THE EROSION OF THE LOW STRATUS SHIELD PRESENTLY IN PLACE ACROSS THE TENNESSEE VALLEY. THINK THAT THIS CLEARING WILL BE GRADUAL AND OCCUR THROUGHOUT THE DAY FROM WEST TO EAST...SO HAVE BEEN CAUTIOUS IN THE UPDATE TO MOVE THINGS ALONG TOO QUICKLY. HOWEVER...DO THINK THAT PARTLY/MOSTLY SUNNY CONDITIONS OVER A GOOD PORTION OF THE AREA SEEM LIKELY BY 21Z...AND POSSIBLY SOONER OVER THE CUMBERLAND PLATEAU AND PORTIONS OF THE SOUTHERN/CENTRAL VALLEY. THIS MAY ALLOW HIGH TEMPERATURES TO CREEP A DEGREE OR TWO HIGHER THAN PREVIOUS THOUGHT...SO HAVE BUMPED THEN UP SLIGHTLY IN THOSE AREAS AS WELL. THE OTHER CHANGE WAS TO PULL POPS BACK AS WELL...AND TAPER THEM OFF FROM WEST TO EAST BY MIDDAY THROUGH THE AFTERNOON. && .PRELIMINARY POINT TEMPS/POPS...
