ONLY A SLIGHT CHANCE OF SHOWERS AND TSTMS WILL BE INCLUDED OVERNIGHT. NO REDEVELOPMENT UPSTREAM BUT MODELS MAINTAIN THE CURRENT WEST NORTHWESTERLY FLOW ALOFT. SOUTHERN AREAS OF THE PLATEAU MAY BE SPARED AS DRIER AIR APPEARS TO BE WORKING INTO THE AREA FROM THE SOUTH. THE DRY AIR IS RATHER DEEP SO I WILL INCLUDE LOWER POPS FOR THAT AREA TONIGHT.
