..NO SVR TSTM AREAS FORECAST...
..AZ...
WIDESPREAD DEEP CONVECTION THAT DEVELOPED ACROSS THE LOWER DESERTS
OF SRN AZ INTO NRN MEXICO HAS STABILIZED MUCH OF THE BUOYANCY ACROSS
THIS REGION. CONTINUED STORM MERGERS AND CLUSTERING WILL SOON
DESTROY WHAT LITTLE INSTABILITY REMAINS AND DEEP CONVECTION WILL
GRADUALLY DECREASE IN INTENSITY/AREAL COVERAGE BY 03Z.
..SRN KS...
VERY WARM SFC TEMPERATURES...LOW-MID 90S...DEVELOPED ACROSS THE HIGH
PLAINS FROM THE NRN TX PANHANDLE INTO SWRN KS THIS AFTERNOON. THIS
CERTAINLY AIDED HIGH BASED THUNDERSTORM ACTIVITY THAT INITIATED
ALONG WEAK SFC BOUNDARY SW OF DDC/GCK AREA. LOSS OF DAYTIME HEATING
SHOULD RESULT IN WEAKENING OF THIS CONVECTION...THOUGH INCREASING
LOW LEVEL WARM ADVECTION COULD ALLOW THUNDERSTORMS TO LINGER FOR
SEVERAL HOURS AS THEY SPREAD SLOWLY EAST.
..ELSEWHERE...
THUNDERSTORMS ARE RAPIDLY WEAKENING ACROSS THE FL PENINSULA AS
BOUNDARY LAYER COOLS. THIS ACTIVITY SHOULD SPREAD SWWD OFF THE GULF
COAST WHERE ACTIVITY MAY LINGER OVER WARMER WATERS INTO THE EVENING
HOURS.
