Area forecast discussion, Jul 11, 4:13 PM CDT, 27 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE JACKSON MS 413 PM CDT FRI JUL 11 2014 .SHORT TERM... FRIDAY NIGHT THROUGH MONDAY AFTERNOON... SHOWERS AND STORMS HAVE BEEN MAINLY CONFINED IN THE HIGHWAY 49 CORRIDOR THIS AFTERNOON...DROPPING TEMPS IN THIS AREA...AND GRADUALLY PROPAGATING TO THE W. DUE TO SOME TRAINING/BACKBUILDING OF STORMS...HEAVY RAINFALL AND FLASH FLOODING IS POSSIBLE IN AREAS THIS EVENING. CONVECTION IN THE W HAS MAINLY BEEN BENIGN...LIKELY DUE TO STRONGER CAPPING WHILE STORMS IN THE E HAVE BEEN AROUND BUT MORE ISOLATED DUE TO DRIER AIR PRESENT. CURRENT THINKING IS THAT STORMS WILL CONTINUE TO THE W/SW AND SOME STRONG STORMS...MAYBE AN ISOLATED SEVERE STORM...WILL BE POSSIBLE INTO THE EVENING IN THE W/SW. LEFT SLIGHT CHANCE POPS THROUGH 03Z SATURDAY IN SW MS/NE LA. LOWS WILL BE SLIGHTLY WARMER THAN MAV DUE TO CLOUDS/STORMS IN THE AREA. WENT NEAR BLEND MAV/ECMWF FOR LOWS TONIGHT. SATURDAY WILL BEGIN A WARM AND MORE HUMID WEEKEND AS THE H5 592-594DM RIDGE BEGINS TO BUILD IN FROM THE CENTRAL PLAINS. TEMPS ALOFT WILL SLOWLY BEGIN TO WARM SATURDAY...BUT DUE TO CLOUDS/STORMS AROUND...GFS SEEMED TOO WARM. CUT MAVMOS AROUND 1-2 DEGREES AT MOST LOCATIONS. THE FLOW ALOFT WILL BECOME MORE NE AS THE SURFACE BOUNDARY AND S/WV SLOWLY DRIFT S. ANY STORMS THAT DEVELOP COULD PRODUCE HEAVY DOWNPOURS DUE TO DECENT MOISTURE. WENT NEAR BLEND OF MAV/ECMWF POPS SATURDAY AFTERNOON. DUE TO CLOUDS SATURDAY NIGHT...LOWS SHOULD BE SLIGHTLY WARMER THAN MAVMOS. THE S/WV AND STATIONARY BOUNDARY WILL BEGIN TO DRIFT N AND SHOWERS/STORMS WILL BE POSSIBLE SUNDAY ALONG/S OF I-20. GFS SEEMED TOO DRY SO WENT NEAR MAV/ECMWF BLEND FOR POPS SUNDAY AFTERNOON. DUE TO INCREASING CLOUDS FROM THE S AND MORE CONVECTION...EXPECTING HIGHS TO BE WARM BUT SLIGHTLY COOLER THAN SATURDAY. ALSO...HEAT INDICES ON SATURDAY AND SUNDAY WILL TOP IN THE 98-102 DEGREE RANGE. THIS AND LOWS BELOW 75 DEGREES EACH EVENING IS BELOW HEAT ADVISORY CRITERIA...BUT WILL NEED TO MONITORED IN LATER SHIFTS FOR MENTION IN THE HWO. LEFT OUT OF THE HWO FOR NOW. LEFT SLIGHT CHANCE POPS THROUGH 03Z MONDAY IN THE FAR SW BUT BETTER CHANCES OF CONVECTION LOOKS TO BE POSSIBLE MONDAY AFTERNOON. LOWS WILL BE IN THE LOWER 70S...SLIGHTLY WARMER THAN MAVMOS. AS THE DEEP UPPER TROUGH OVER THE GREAT LAKES/HIGH PLAINS TAKES SHAPE MONDAY...EXPECT THE UPPER RIDGE TO BEGIN TO BREAK DOWN ON THE REGION. HIGHS WILL STILL BE IN THE LOW/MID 90S WITH SCATTERED SHOWERS AND STORMS MONDAY AFTERNOON. RELEVANT PORTION OF PREVIOUS LONG TERM DISCUSSION IS ATTACHED. /DC/ .LONG TERM... TUESDAY THROUGH FRIDAY... BROAD RIDGING WILL BE IN PLACE OVER THE REGION AT THE START OF THE LONG TERM. THIS WILL BRING SLIGHTLY ABOVE NORMAL TEMPERATURES TO THE REGION. THE MAIN STORY OF THE EXTENDED FORECAST IS IN THE PATTERN CHANGE THAT WILL BE UNDERWAY AT THE START TO MIDDLE OF THE WORK WEEK. A LARGE UPPER TROUGH WILL TAKE SHAPE AND SET UP OVER THE GREAT LAKES REGION. THIS WILL SEND AN UNSEASONABLY STRONG COLD FRONT OUR WAY FOR TUESDAY INTO WEDNESDAY. SHOWERS AND THUNDERSTORMS WILL OCCUR ALONG AND AHEAD OF THE FRONT ON TUESDAY BUT AT THIS TIME PARAMETERS DONT LOOK VERY IMPRESSIVE FOR SEVERE STORMS. AS THE FRONT MOVES THROUGH...CHANCES FOR RAIN WILL CONTINUE ESPECIALLY IN THE SOUTH WHERE DRIER AIR WILL BE SLOWER TO MOVE IN. TEMPERATURES THROUGH MID WEEK WILL BE FAIRLY PLEASANT IN THE 80S FOR MOST ALL LOCATIONS AND EVEN LOWER 80S IN THE NORTH. OVERNIGHT LOWS WILL BE IN THE 60S. AS THE UPPER TROUGH REMAINS EXTENDED ACROSS THE SOUTH...SEVERAL WEAK DISTURBANCES IN THE FLOW WILL MOVE ACROSS OUR AREA THROUGH THE END OF THE WEEK. THESE WILL COMBINE WITH MOISTURE CHARACTERIZED BY ~1.7 INCH FORECAST PW VALUES...AND KEEP AT LEAST SOME CHANCE FOR RAIN IN THE FORECAST. TEMPERATURES WILL REMAIN BELOW NORMAL THROUGH THE END OF THE WEEK. /28/DC/ && .AVIATION...TSRA WILL CONTINUE TO SLOWLY DRIFT W AND CONTINUE TO KEEP KJAN/KHKS NEAR MVFR/IFR CONDITIONS OVER THE NEXT FEW HOURS. CONDITIONS WILL IMPROVE AT KHBG AS TSRA/SHRA MOVE W. VCTS IS POSSIBLE AT ALL TAF SITES THROUGH THE EARLY EVENING. CONVECTION WILL WIND DOWN DURING THE EARLY EVENING WITH MVFR VISIBILITIES IN MIST DEVELOPING AFTER 06Z IN THOSE AREAS THAT GET RAINFALL TODAY. VFR CONDITIONS WILL RETURN BY 14Z DUE TO INCREASED MIXING. /26/DC/ && .PRELIMINARY POINT TEMPS/POPS...
