AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE JACKSON MS 230 CDT WED JUN 10 2003 WEAK SHORTWAVE RIDGING FORECAST EARLY TONIGHT IN THE WAKE OF TODAYS TROUGH. MODELS AGREE THAT ANOTHER MCS WILL DEVELOP OVERNIGHT UPSTREAM BUT DISAGREE ON THE LOCATION. WILL LEAN TOWARD THE AVN SOLUTION WHICH MAINTAINS SYSTEM FARTHER WEST THRU DAYBREAK BUT WILL KEEP CHANCE POPS WRN ZONES FOR THU MORNING. COLD FRONT REMAINING N OF REGION UNTIL THE WEEKEND BUT OUTFLOW BOUNDARIES WILL LINGER TO FOCUS CONVECTION. SHORTWAVE TRACK PERSISTS ACROSS THE REGION AND UPPER DIVERGENCE INCREASES THU AS THE UPPER JET NOSES INTO SW MS. ALTHOUGH SHORTWAVE STRENGTH LOOKS WEAKER TOMORROW AND 850 MB FLOW TO BE LIGHTER...INSTABILITY WILL BE SUFFICIENT IN OUR REGION OF DEWPOINTS IN THE LOW TO MID 70S FOR AT LEAST HIGH END CHANCE POPS MOST LOCATIONS. MOST CONCERNED ABOUT POSSIBILITY OF ISOLATED SEVERE STORMS CENTRAL AND SRN ZONES...WHERE UPPER DIVERGENCE LOOK STRONGER AND SHORTWAVE MOVES THRU. HOWEVER... INSTABILITY LOOKS GREATEST NRN ZONES WHERE HIGH THETAE AND CAPE MAX SITS NEAR THE MS/TN BORDER. CHANCE LOOKS SMALLER NRN ZONES AT THIS TIME BUT WILL BROAD BRUSH ISOLATED SEVERE POSSIBILITY ALL ZONES FOR THU. WILL MAINTAIN CHANCE FOR CONVECTION THU NIGHT AS THE NEXT SHORTWAVE SHIFTS INTO THE AREA. AVN INCREASES STRENGTH OF VORT LOBE AFTER MIDNIGHT WHICH SUGGESTS POSSIBILITY OF MCS DEVELOPMENT LATE. OTHER FEATURES NO NOT OFFER MUCH SUPPORT TO THIS AT THIS TIME SO WILL GO WITH DECREASE IN COVERAGE AND INTENSITY OF CONVECTION THU NIGHT BUT MAINTAIN CHANCE OF SHOWERS AND THUNDERSTORMS. AIR MASS REMAINS UNSTABLE FRIDAY WITH SURFACE DEWPOINTS IN THE 70S. VERTICAL VELOCITY AND UPPER DIVERGENCE VALUES INCREASE IN THE AFTERNOON AS YET ANOTHER SHORTWAVE TRACKS ACROSS THE AREA...WHICH MEANS A GOOD CHANCE OF THUNDERSTORMS AGAIN FOR FRIDAY. WILL KEEP CHANCE FOR THUNDERSTORMS FRIDAY NIGHT. SRN TIP OF GOOD DYNAMICS SWINGS ACROSS NW MS OVERNIGHT AS THE SURFACE BOUNDARY DRIFTS INTO NW AR. WILL LEAVE KEEP ISOLATED CONVECTION OTHER ZONES...MAINLY IN THE EVENING HOURS. GOOD DIVERGENT PATTERN SETTING UP ALOFT AS THE UPPER LOW SETTLES INTO THE MIDWEST THIS WEEKEND. CHANCE OF THUNDERSTORMS FOR SATURDAY AS THE TROUGH DEEPENS JUST UPSTREAM. GOOD THUNDERSTORM CHANCE WILL CONTINUE SATURDAY NIGHT...INCREASING SUNDAY AS THE SURFACE FRONTAL BOUNDARY FINALLY SAGS INTO NW MS. THE 12Z GFS DRAGS THE BOUNDARY SWD ACROSS THE FORECAST AREA SUNDAY WHILE THE 00Z RUN MAINTAINS THE BOUNDARY ALONG OF N OF NRN SECTIONS OF THE FORECAST AREA THROUGH WED. UPPER LOW NOW MAINTAINED JUST W OF THE MS RIVER THRU WED SO WILL KEEP THUNDERSTORM CHANCE IN THROUGH EXTENDED FORECAST PERIODS. .JAN... AR...NONE. LA...NONE. MS...NONE.
