STARTING TO GET SHOWER ACTIVITY POPPING UP JUST TO OUR N AHEAD OF OUR NEXT SFC SYSTEM. CURRENT THINKING IS THAT OUR LOW POPS SHOULD HANDLE AFTERNOON ACTIVITY SUFFICIENTLY. NO ADJUSTMENTS MADE THERE. DID HOWEVER...TWEAK UP MAX TEMPS A TAD ACROSS MAINLY NE COUNTIES BASED UPON SLOWER CLOUD DEVELOPMENT...OB TRENDS AND LATEST MODEL DATA. UPDATED GRIDS/PRODUCTS ALREADY SENT. 08 && .DISCUSSION... /ISSUED 339 AM CDT FRI JUL 9 2010/ STILL IMPRESSIVELY WARM ACROSS THE AREA THIS MORNING WITH UPPER 70S AND LOWER 80S IN THE URBAN AREAS AS OF 3 AM. THE UPPER RIDGE IS THANKFULLY GIVING WAY TODAY AS A TROUGH MOVES ACROSS THE GREAT LAKES TO UPPER TENNESSEE VALLEY REGIONS. THIS WILL PUSH A SURFACE BOUNDARY TO NEAR THE NORTHERN COUNTIES THIS AFTERNOON AND EVENING. RAIN CHANCES GO UP AS THE BOUNDARY APPROACHES THE NORTHERN COUNTIES BUT THE BULK OF THE WIDESPREAD SHOWERS SHOULD STAY OUT OF THE AREA. TEMPERATURES WILL RISE INTO THE MID AND UPPER 90S ALTHOUGH IF ENOUGH CLOUD COVER WERE TO MOVE IN ACROSS THE NORTH THEN LOWER 90S WOULD BE MORE LIKELY IN THOSE AREAS. MODELS ARE REALLY SPLIT ON THE TIMING DETAILS OVER THE NEXT 48 HOURS BUT OVERALL...A BETTER CHANCE OF SCATTERED SHOWERS AND THUNDERSTORMS BEGINS THIS AFTERNOON AND LASTS THROUGH SATURDAY AS SEVERAL RIPPLES IN THE UPPER FLOW AND THE SURFACE BOUNDARY MOVE THROUGH. TEMPERATURES BACK TO NEAR NORMAL VALUES FOR SATURDAY. THE 00Z MODEL TREND TONIGHT WAS TO PUSH MOST OF THE PRECIP SOUTH OF THE AREA BY SUNDAY WITH TEMPERATURES BACK INTO THE MID 90S SUNDAY AFTERNOON. A SERIES OF WEAK DISTURBANCES MOVES THROUGH MONDAY THROUGH WEDNESDAY ALLOWING FOR SCATTERED SHOWERS AND THUNDERSTORMS THAT WILL BE MAINLY DIURNAL. THEREAFTER...ANOTHER STOUT UPPER RIDGE BEGINS TO ENGULF THE AREA. WE ARE CURRENTLY PROJECTED TO BE ON THE EASTERN PERIPHERY OF THIS ONE WHICH SHOULD ALLOW FOR ISOLATED RAIN CHANCES DURING THE AFTERNOON AND EARLY EVENING THURSDAY AND FRIDAY. AFTERNOON TEMPERATURES WELL INTO THE 90S WITH LOWS IN THE UPPER 60S TO MID 70S. 88 && .AVIATION...18Z TAF DISCUSSION. WIDELY SCATTERED CONVECTION ACROSS THE SE C AL COUNTIES MAINLY DIURNALLY DRIVEN BUT COULD IMPACT THE MGM/TOI TERMINAL OVER THE NEXT FEW HRS. OTHER ACTIVITY ACROSS THE NRN PARTS OF AL WILL BE SLOWER TO MOVE INTO THE C AL AND THUS AFFECT THE NRN TAF SITES. WILL GO WITH ONLY CBS FOR NOW FOR THE MOST PART...AS ANY ISOLATED ACTIVITY WITH BE TOUGH TO PINPOINT. GREATER MID LEVEL CLOUD COVER WILL BE USHERED IN TONIGHT AHEAD OF OUR SFC FRONT. COULD GET SOME MINOR BR AT SRN SITES TONIGHT WITH A COMBO OF AFFECTS FROM AFTERNOON CONVECTIVE MOISTURE AND LESS HIGH CLOUDINESS. NOTICE...KEET TAF WILL HAVE (AMD LTD TO VIS WIND AND WX) AMENDED TO THE END OF THE FORECAST THROUGH THE END OF 2010.
