AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE HUNTSVILLE AL 325 PM CDT FRI AUG 27 2010 .DISCUSSION... ISOLATED TO SCATTERED SHOWERS AND THUNDERSTORMS HAVE DEVELOPED JUST SOUTH AND EAST OF THE FORECAST AREA THIS AFTERNOON ALONG A WEAK INVERTED SURFACE TROUGH OVER NORTHEAST ALABAMA. THIS CONVECTION WILL PERSIST THROUGH THE EVENING HOURS AND MAY SNEAK INTO CULLMAN...MARSHALL...AND DEKALB COUNTIES BEFORE ALL IS SAID AND DONE. AS A RESULT...HELD ONTO A SLIGHT CHANCE OF RAIN FOR THESE AREAS BUT THINK MOST LOCATIONS WILL BE DRY TONIGHT. WITH A MORE EASTERLY TO SOUTHEASTERLY WIND CONTINUING OVERNIGHT...LOW TEMPERATURES WILL STAY UP SEVERAL MORE DEGREES THAN PREVIOUS NIGHTS WITH MOST LOCATIONS ONLY DIPPING INTO THE UPPER 60S. THERE COULD BE SOME PATCHY FOG DEVELOPMENT AFTER MIDNIGHT BUT SHOULD NOT BE WIDESPREAD ENOUGH TO INCLUDE IN THE FORECAST AT THIS TIME. FOR THE WEEKEND...SIGNIFICANT CHANGES WERE MADE TO THE CURRENT FORECAST AT LEAST FOR SUNDAY AS DEEP TROPICAL MOISTURE RETURNS TO THE TENNESSEE VALLEY. MODELS ARE IN GOOD AGREEMENT DURING THIS TIME FRAME SO FEEL MORE CONFIDENT ABOUT INTRODUCING PRECIPITATION INTO THE FORECAST FOR THE SATURDAY NIGHT THROUGH MONDAY TIME FRAME. FOR SATURDAY...BELIEVE DRY CONDITIONS WILL PREVAIL WITH ONLY A SLIGHT CHANCE OF RAIN EXPECTED FOR FAR SOUTHERN PORTIONS OF THE FORECAST AREA. HIGH TEMPERATURES WILL BE QUITE WARM WITH HIGHS COMPARABLE TO TODAY WITH LOW 90S EXPECTED. BY SATURDAY NIGHT...SOUTHERLY FLOW WILL INCREASE ACROSS THE REGION AS THE SURFACE HIGH EAST OF THE AREA MOVES SOUTH. MAIN QUESTION WILL BE HOW FAST PRECIPITATION CAN MOVE NORTH AS A WEAK UPPER LEVEL DISTURBANCE APPROACHES THE AREA. FOR NOW...HAVE ONLY INTRODUCED POPS FOR LOCATIONS SOUTH OF THE TENNESSEE RIVER BUT THINK CONVECTION WILL INCREASE IN COVERAGE AFTER SUNRISE. THE MOST SIGNIFICANT CHANGE TO THE FORECAST HAS BEEN MADE TO SUNDAY AS THE ONCE MOSTLY DRY AND HOT DAY HAS NOW TURNED INTO MORE OF A WET AND COOL DAY. AMPLE MOISTURE WILL BE AVAILABLE FOR SHOWERS AND THUNDERSTORMS ON SUNDAY WITH THE BEST CHANCES OCCURRING FROM WEST TO EAST. POPS HAVE BEEN INCREASED SIGNIFICANTLY AND HIGH TEMPERATURES HAVE BEEN LOWERED BY SEVERAL DEGREES. BY THE START OF THE WORK WEEK...CHANCES FOR ISOLATED TO SCATTERED SHOWERS AND THUNDERSTORMS WILL CONTINUE ON MONDAY BEFORE THE SURFACE HIGH FINALLY BUILDS BACK OVER THE AREA TUESDAY. A RETURN TO DRY AND HOT WEATHER CAN BE EXPECTED FOR MID TO LATE WEEK AS HIGH PRESSURE REMAINS IN CONTROL OF THE WEATHER OVER THE AREA. HIGH TEMPERATURES WILL BE SEVERAL DEGREES ABOVE NORMAL IN THE LOW 90S WHILE LOWS ARE CLOSER TO SEASONAL NORMALS IN THE MID 60S DURING THIS TIME FRAME. && .PRELIMINARY POINT TEMPS/POPS...
