AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE JACKSON MS 250 PM CDT TUE SEP 16 2014 .SHORT TERM...TONIGHT THROUGH THURSDAY NIGHT...WATER VAPOR IMAGERY/RUC ANALYSIS HAD A SHORTWAVE MOVING OVER NORTHERN MISSISSIPPI THIS AFTERNOON THAT WAS HELPING SUPPORT A WEAK COLD FRONT DRIFT THROUGH OUR CWA. LATEST SURFACE ANALYSIS HAD THIS COLD FRONT SOUTH OF INTERSTATE 20 AND A 1022MB HIGH CENTERED OVER THE MID MISSISSIPPI RIVER VALLEY. LOCAL RADARS WERE SHOWING ISOLATED SHOWERS AND THUNDERSTORMS ALONG AND AHEAD OF THE FRONT. THE COLD FRONT MAY DRIFT JUST SOUTH OF OUR CWA BY THIS EVENING ENDING RAIN CHANCES BUT WL CARRY LOW POPS ACROSS THE HIGHWAY 84 CORRIDOR FOR NOW. THE SURFACE HIGH WILL SHIFT EAST AND WEAKEN TONIGHT INTO WEDNESDAY. ALTHOUGH THE SHORTWAVE WILL SHIFT EAST TONIGHT AS WELL...RIDGING ALOFT WILL AMPLIFY IN THE WEST WHILE UPPER LEVEL TROUGHING DEEPENS IN THE EAST RESULTING IN A NORTHWEST FLOW ALOFT OVER OUR CWA. THIS WILL HELP THE COLD FRONT DRIFT SOUTH OF OUR CWA BY WEDNESDAY MORNING AND THEN STALL NEAR THE GULF COAST. SLIGHTLY COOLER AND DRIER AIR IS EXPECTED OVER OUR CWA WEDNESDAY. THE 12Z TUE JAN SOUNDING SHOWED A PW OF 1.95INCHES. BY 12Z WEDNESDAY PWS ARE EXPECTED TO BE AROUND AN INCH AND A THIRD. SURFACE DEW POINTS WILL DROP IN THE 60S OVERNIGHT ALLOWING MOST SITES TO BOTTOM OUT IN THE MID 60S WEDNESDAY MORNING. NORMAL LOWS FOR THIS TIME OF THE YEAR RUN 63-66F. NORTHWEST FLOW ALOFT WL CONTINUE OVER OUR REGION THROUGH THURSDAY NIGHT AND MODELS AGREE THAT A COUPLE OF SUBTLE SHORTWAVES WILL SET OFF CONVECTION UPSTREAM WEDNESDAY AND THURSDAY AFTERNOONS THAT MAY MOVE INTO OUR DELTA REGION EACH EVENING. THE WESTERN PORTION OF STALLED COLD FRONT WILL DRIFT BACK NORTH A BIT WEDNESDAY AND THURSDAY RESULTING IN A CHANCE FOR ISOLATED STORMS OVER OUR SOUTHWEST EACH AFTERNOON AS WELL.

WHAT HAS CHANGED OVER THE LAST 24 HRS IS NOW THE EURO/GFS ARE IN BETTER AGREEMENT NOW ON THE PERIOD FOR EARLY NEXT WEEK. TIMING IS MUCH BETTER ON THE TROUGH AMPLIFICATION AND SOUTHWARD PUSH OF A DECENT LATE SEP COOL FRONT. FOR FRI...THE NW FLOW PATTERN WILL HELP PUSH A BACKDOOR FRONT INTO PART OF THE CWA. OVERALL DRIER AIR WILL MOVE IN BY FRI ALLOWING FOR LESS PRECIP CHANCES INTO SAT. MOISTURE WILL RETURN FOR SUN INTO MON AS THE LARGER TROUGH TAKES SHAPE AND PUSHES A STRONGER FRONT OUR WAY. BETTER PRECIP CHANCES LOOK TO RETURN FOR PART OF SUN INTO EARLY MON AS MOISTURE GETS FOCUSED ALONG AND AHEAD OF THE FRONT. THERE AREA INDICATIONS THAT THE MOISTURE COULD BE ON THE HIGH SIDE AS LEFTOVER MOISTURE FROM T.S. ODILE MAY MAKE ITS WAY INTO THE REGIONAL CIRCULATION AS OUR FRONTAL SYSTEM TAKES SHAPE EARLY NEXT WEEK. TEMPS WILL CONTINUE TO RUN ABOVE CLIMO NORMS FROM THU-SUN. SOME LOCATIONS (E/NE) MAY SEE LOWS NEAR NORMAL FRI MORN BUT THEN WARM AGAIN OVER THE WEEKEND. CONDITIONS LOOK TO SHIFT TO MORE SEASONAL READINGS AFTER THE FRONT WITH SOME POTENTIAL FOR BELOW NORMAL READINGS IF THE PATTERN CAN BECOME MORE AMPLIFIED. /CME/ && .AVIATION...VFR CONDITIONS PREVAIL ACROSS ALL TAF SITES THIS AFTERNOON AND THIS WILL CONTINUE THROUGH MUCH OF THE PERIOD. AN ISOLATED SHOWER OR THUNDERSTORM MAY BRING A BRIEF BOUT OF MVFR/IFR CEILINGS THIS AFTERNOON AND EVENING AT HBG AS A WEAK COLD FRONT MOVES ACROSS THE AREA.
