NWS Jackson, MS wrote its last area forecast discussion before the first event at May 29, 3:25 AM CST, 6 hours 15 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE JACKSON MS 425 AM CDT FRI MAY 29 2015 .SHORT TERM...TODAY THROUGH SATURDAY NIGHT...AFTER A RELATIVELY DRY THURSDAY RAIN CHANCES LOOK TO INCREASE GOING INTO THE WEEKEND. EARLY MORNING WATER VAPOR IMAGERY/RAP ANALYSIS HAD A SHORTWAVE OVER THE SOUTHERN PLAINS THAT WAS MOVING EAST AND A SECOND MORE POTENT SHORTWAVE DROPPING SOUTHEAST ACROSS WYOMING. THE FIRST SHORTWAVE WAS HELPING TO MAINTAIN PLENTY OF CONVECTION OVER THE EASTERN HALF OF TEXAS AND OKLAHOMA EARLY THIS MORNING. THIS SHORTWAVE IS PROGGED TO WEAKEN AS IT MOVES OVER OUR CWA THIS EVENING BUT IT SHOULD HELP PROLONG CONVECTION THROUGH THE NIGHT...AT LEAST OVER THE NORTHERN PORTIONS OF OUR CWA. LOCAL RADARS WERE CURRENTLY SILENT OVER OUR CWA BUT DAYTIME HEATING WILL LEAD TO ISOLATED TO SCATTERED COVERAGE OF STORMS THIS AFTERNOON PRIMARILY OVER THE EASTERN HALF OF THE CWA. FOCUS FOR ACTIVITY WILL SHIFT TO THE NORTHWEST THIS EVENING AS THE SHORTWAVE MOVES IN. BY SATURDAY PWATS OVER THE WHOLE CWA WILL BE BACK UP AROUND AN INCH AND THREE QUARTERS. THAT SECOND SHORTWAVE WILL DROP OVER THE CENTRAL PLAINS DURING THE DAY AND HELP SUPPORT A COLD FRONT. MORE WIDESPREAD ACTIVITY IS EXPECTED TO DEVELOP OVER OUR CWA SATURDAY AFTERNOON AND EVENING AHEAD OF THE APPROACHING COLD FRONT. MODEL CONSENSUS HAS THE COLD FRONT ACROSS OUR NORTHWEST ZONES BY SUNRISE SUNDAY. ALTHOUGH THE POTENTIAL FOR SEVERE STORM DEVELOPMENT LOOKS TO REMAIN LOW THROUGH SATURDAY NIGHT...LOCALLY HEAVY RAIN OF SEVERAL INCHES WILL BE POSSIBLE OVER THE NORTHWEST PORTIONS OF THE AREA AT THAT TIME. /22/ .LONG TERM...SUNDAY THROUGH THE MIDDLE OF NEXT WEEK...SOME UNCERTAINTY IS AGAIN CREEPING INTO THE LONG TERM FORECAST THIS SHIFT DUE TO THE LATEST OPERATIONAL EUROPEAN MODEL RUN COMING WITH A MORE PROGRESSIVE TAKE ON THE TROUGH COMING INTO THE LOWER MS VALLEY SUNDAY. PREVIOUS MODEL CONSENSUS WAS STRONGLY IN FAVOR OF THIS TROUGH ENERGY CUTTING OFF OVER TOP OF OUR REGION AND SWIRLING OVERHEAD WELL INTO NEXT WEEK. CONSENSUS STILL FAVORS THIS SOLUTION BUT THE MENTIONED EURO IDEA REDUCES CONFIDENCE AND SUGGESTS SOME CHANCE THAT PROLONGED ABOVE NORMAL RAIN CHANCES MIGHT SHIFT EAST OF OUR REGION FASTER THAN ANTICIPATED. BUT AT LEAST THESE UNCERTAINTIES WAIT UNTIL AFTER SUNDAY TO SHOW UP IN THE MODELS SO CONFIDENCE IN NUMEROUS SHOWERS AND THUNDERSTORMS (ESPECIALLY SUNDAY AFTERNOON) IS PRETTY HIGH. WE DEBATED THROWING IN MENTION OF LIMITED SEVERE STORM AND FLOODING POTENTIAL IN THE HWO FOR SUNDAY...BUT IN THE END WE DECIDED TO HOLD OFF A BIT LONGER SINCE THE CONSENSUS SOLUTION STILL WEAKENS WIND SHEAR AND GULF MOISTURE TRANSPORT QUITE A BIT AS THE OVERALL SYSTEM SHIFT EAST OUT OF THE PLAINS. OF COURSE HIGH INSTABILITY CAN YIELD SEVERE POTENTIAL WITHOUT REQUIRING MUCH WIND SHEAR...BUT IN THIS CASE MODEST LAPSE RATES AND POTENTIAL FOR MORNING TO MIDDAY CLOUDS MAY LIMIT SIGNIFICANT AFTERNOON DESTABILIZATION. OF COURSE IT IS STILL POSSIBLE FOR SOME GUSTY STORMS TO BE ABOUT SUNDAY AFTERNOON AND FOR A FEW ISOLATED LOCATIONS TO PICK UP ONE TO INCHES OF RAINFALL...SO PLAN ACCORDINGLY. THERE STILL COULD BE ENOUGH MOISTURE TRANSPORT INTO THE HEART OF THE REGION TO KEEP SHOWERS AND A FEW STORMS GOING IN SOME LOCATIONS WELL INTO THE NIGHT SUNDAY NIGHT...BUT BY MONDAY REPOSITIONING OF THE TROUGH AXIS AND ASSOCIATED AXES OF MOISTURE TRANSPORT AND MOISTURE ADVECTION SHOULD FUEL THE HIGHEST AMOUNT OF DAYTIME THUNDERSTORM PRODUCTION EAST OF THE NATCHEZ TRACE. SOME STORM CHANCES WILL LIKELY PERSIST BACK WEST INTO THE ARKLAMISS DELTA AS WELL ON MONDAY...BUT THIS PROSPECT COULD POTENTIALLY CHANGE IF THE EURO IS CORRECT WITH ITS LATEST PROGRESSIVE TAKE OF UPPER LEVEL TROUGH MOVEMENT. THE FORECAST FOR TUESDAY THROUGH THURSDAY COULD BE IMPACTED A GREAT DEAL IF THIS TROUGH IS INDEED PROGRESSIVE AND CUTS OFF FROM THE JET- LEVEL STEERING CURRENTS TO OUR EAST. IN THAT CASE AFTERNOON SHOWER AND STORM CHANCES COULD BE MUCH MORE LIMITED THAN WHAT THE FORECAST CURRENTLY REPRESENTS (ESPECIALLY WEST OF I-55) WHILE DAYTIME TEMPERATURES MAY TREND WARMER. HOWEVER...AS MENTIONED PREVIOUSLY...THE CONSENSUS AND CONSISTENT MODEL SOLUTION OF TROUGH ENERGY CUTTING OFF OVERHEAD STILL ARGUES FOR ABOVE NORMAL RAIN CHANCES TO CONTINUE WELL INTO THE WEEK WITH CLOUDS AND PRECIP KEEPING TEMPS DOWN A FEW DEGREES. HOPEFULLY BY THIS TIME TOMORROW MODEL CONSENSUS WILL STRENGTHEN REGARDING SOLUTIONS FOR OUR REGION OVER THIS TIME FRAME. /BB/ && .AVIATION...IFR CIGS WERE BEING REPORTED ACROSS THE CNTRL AND NE PORTIONS OF THE AREA AT 09Z AND IFR/LIFR CIGS ARE EXPECTED TO DEVELOP OVER MOST OF THE AREA BY 11Z. CONDITIONS WILL THEN IMPROVE BY 15Z. VFR CONDS WILL PREVAIL AFTER 15Z UNTIL ISOLD TO SCT COVERAGE OF TSTMS DEVELOP DURING THE AFTN. GREATER COVERAGE IS EXPECTED EAST OF THE MS RIVER THIS AFTN THEN FOCUS OVER THE NW PORTIONS OF THE AREA THIS EVNG.
