.DISCUSSION...SURFACE FRONT CURRENTLY MOVING SOUTHEASTWARD ACROSS
MIDDLE TENNESSEE THIS AFTERNOON, WITH ONLY SCATTERED CELLS
OCCURRING EAST AND SOUTH OF NASHVILLE. EXPECT THIS ACTIVITY TO
DISAPPEAR AFTER SUNSET AS THE FRONT MOVES OUT OF THE MID STATE,
LEAVING US WITH A SIGNIFICANTLY COOLER, DRIER AIR MASS IN ITS
PLACE. MODELS SHOW A LARGE BLOCKING HIGH DEVELOPING BOTH AT THE
SURFACE AND ALOFT, WHICH WILL KEEP DRY AIR LOCKED IN THROUGHOUT
THE UPCOMING WEEK AS TEMPERATURES GRADUALLY WARM BACK TO NORMAL
READINGS FOLLOWING THE INITIAL COOL-DOWN. BOTH THE GFS AND ECMWF
BRING SOME SORT OF TROPICAL SYSTEM NORTHWESTWARD INTO MIDDLE
TENNESSEE NEXT WEEKEND, ALTHOUGH THERE ARE MARKED DIFFERENCES IN
TIMING AND QPF. NEVERTHELESS, THIS REPRESENTS OUR NEXT APPRECIABLE
CHANCE OF PRECIPITATION FOLLOWING A DRY, FALL-LIKE WEEK.
