WITH LOW LEVEL EAST TO NORTHEAST WINDS...THE GFS AND ETA ARE INDICATING SLIGHTLY LOWER 1000-850 THICKNESSES...FOR A TAD BELOW NORMAL HIGH TEMPERATURES. WITH THE TROUGH NEARBY...AND NEBULOUS CONVECTIVE BOUNDARIES LIKELY...I AM HARD PRESSED TO FIND A PREFERRED LOCATION AND TIME FOR CONVECTION. THEREFORE...I HAVE LEFT AT LEAST 20 POPS THROUGH THURSDAY EVENING. BY FRIDAY...THE TROUGH IS PROGGED TO SLIDE FAR ENOUGH WEST AS THE STRONG CENTRAL CONUS RIDGE BUILDS INTO THE SOUTH. WITH THIS IN MIND...WE MAY BE END THUNDERSTORM CHANCES BY FRIDAY. HOWEVER...AS THE PREVIOUS FORECAST HAD A SLIGHT CHANCE...I WILL AVOID FLIP FLOPPING ON THIS MODEL RUN. IN ANY CASE...TEMPERATURES WILL BE BACK TO THE NORMAL MID TO UPPER 90S BY NEXT WEEKEND.
