AREA FORECAST DISCUSSION...UPDATE NATIONAL WEATHER SERVICE HUNTSVILLE AL 1035 AM CDT FRI AUG 4 2006 .UPDATE... MORNING SFC ANALYSIS INDICATES FRONTAL BOUNDARY IS STRETCHED ACROSS NORTHWEST TENNESSEE AND CENTRAL ARKANSAS AND IS SLOWLY SINKING SOUTHWARD. SMALL COMPLEX OF SHOWERS AND THUNDERSTORMS CONTINUES ACROSS NE ARKANSAS AND THE MISSOURI BOOTHEEL AND IS SLOWLY MOVING SEWRD. CLOSER TO HOME...SKIES ARE MOSTLY SUNNY AND TEMPERATURES HAVE WARMED INTO THE MID TO UPPER 80S. WINDS ARE CURRENTLY LIGHT AND VARIABLE ACROSS THE AREA BUT WILL BEGIN TO SHIFT TO THE NORTHWEST AND INCREASE TO AROUND 10 MPH FOR THE AFTERNOON. AREA OF SHOWERS AND THUNDERSTORMS WILL CONTINUE TO MOVE SLOWLY SOUTH INTO THE TN VALLEY THIS AFTERNOON. THE FRONT WILL BE MOVING THROUGH DURING THE AFTERNOON HOURS...AND SO EXPECT DAYTIME HEATING TO AID IN THUNDERSTORM DEVELOPMENT. COVERAGE SHOULD REMAIN SCATTERED WITH ONLY MARGINAL FORCING ALONG THE FRONT...AND SO CURRENT FORECAST OF MID RANGE CHANCE POPS LOOKS REASONABLE. A FEW OF THESE STORMS COULD BECOME STRONG WITH GUSTY WINDS AND LOCALLY HEAVY RAINFALL. ABUNDANT SUNSHINE THROUGH THE MORNING HOURS WILL HELP BOOST TEMPS WELL INTO THE 90S AGAIN TODAY...AND WITH SEVERAL LOCATIONS ALREADY NEAR 90 WILL NEED TO ADJUST HIGHS SLIGHTLY UPWARD. A FEW LOCATIONS ARE ALREADY REPORTING HEAT INDICES IN THE UPPER 90S WITH DEWPOINTS AROUND 70 SO WILL ALSO ADD A REMARK ABOUT HEAT INDICES INTO THE ZONE FORECAST. 24 && .PREV DISCUSSION... THE GFS/NAM BOTH RETREAT THE FRONT NORTHWARD DURING THE DAY ON SATURDAY. IN ADDITION...THE AFOREMENTIONED H5 LOW IS PROGGED TO MOVE INTO THE NRN GULF OF MEX ON SAT...AND INTO THE DEEP SOUTH SATURDAY NIGHT. OVERALL...THE NAM IS A BIT FURTHER SOUTH WITH THIS FEATURE WHILE THE GFS BRINGS IT NORTHWARD INTO NRN MS. THE COMBINATION OF THE FRONT AND U/L TROUGH/SHEAR AXIS WILL KEEP SLGT CHC/CHC POPS IN THE FCST THROUGH THE WEEKEND. THE L/W RIDGE WILL BUILD ACROSS THE SRN PLAINS DURING THE EARLY PORTION OF THE UPCOMING WORK WEEK. THIS WILL PLACE THE TN VLY IN A GENERAL NW FLOW ALOFT. WITH THIS PATTERN...ISOLD/WDLY SCT AFTN AND EVENING CONVECTION SEEMS A GOOD BET. EXPECT MAX/MIN TEMPS TO BE FAIRLY UNIFORM THROUGH THE UPCOMING WORK WEEK WITH HIGHS IN THE L/M 90S AND MINS IN THE L70S. 15/CBD && .HUN WATCHES/WARNINGS/ADVISORIES... AL...NONE. TN...NONE. &&
