NWS Jackson, MS wrote its last area forecast discussion before the first event at May 28, 3:41 PM CST, 31 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE JACKSON MS 441 PM CDT FRI MAY 28 2010 .DISCUSSION... TONIGHT THROUGH SUNDAY... SUBSTANTIAL HEIGHT FALLS ACROSS THE ARKLAMISS THIS AFTN AND TONIGHT ARE ASSOCIATED WITH A SOUTHWARD MOVING MID LEVEL SHORTWAVE TROUGH. SFC TEMPS IN THE MID/UPPER 80S AND DEWPOINTS IN THE MID/UPPER 60S HAVE BEEN SUFFICIENT TO PRODUCE ISOLATED PULSE TO MULTICELL TYPE SEVERE STORMS GIVEN STRONG LOW-MID LEVEL LAPSE RATES WITH VERTICAL TOTALS IN THE MID/UPPER 20S AND ~15KTS OF MID LEVEL FLOW. EXPECT ACTIVITY OVER NE LA/SW MS WILL CONTINUE TO DEVELOP SOUTHWARD AND EVENTUALLY DIMINISH WITH LOSS OF HEATING. MEANWHILE...ACTIVITY OVER THE TN VALLEY REGION IS TRYING TO DEVELOP INTO NE PORTIONS OF THE FORECAST AREA AND THIS TREND SHOULD CONTINUE AS WE GO INTO THE EVNG HOURS...BUT EXPECT INTENSITY TO DIMINISH AFTER SUNSET. A FEW SHOWERS COULD CONTINUE THROUGHOUT THE NIGHT AS THE MID LEVEL TROUGH CLOSES OFF. THE UPPER LOW WILL REMAIN IN PLACE FOR SATURDAY THROUGH SUNDAY WITH MORE DIURNAL ISOLATED TO SCATTERED TSTM ACTIVITY EXPECTED. MID LEVEL LAPSE RATES LOOK EVEN STEEPER FOR SATURDAY WITH VERTICAL TOTALS POSSIBLY EXCEEDING 30 AS SFC TEMPS RISE WELL INTO THE 80S. THE INSTABILITY COMBINED WITH DCAPE ~1000 J/KG MEANS WE COULD SEE AN ACTIVE WET MICROBURST DAY SATURDAY WITH POTENTIAL HAIL UP TO AROUND QUARTER SIZE AND WIND GUSTS OF 50 TO 60 MPH. THE ENVIRONMENT FOR SUNDAY SHOULD NOT BE QUITE AS FAVORABLE AS MID LEVEL WARMING TAKES PLACE. /EC/ SUNDAY NIGHT THROUGH FRIDAY... CONCERNS WILL BE THE FLATTENING OF THE UPPER RIDGE AS A BROAD UPPER TROUGH DEVELOPS OVER THE REGION BY THURSDAY INTO FRIDAY...AND ASSOCIATED POPS AND TEMPS THROUGH THE PERIOD. GLOBAL MODELS AS WELL AS CANADIAN GEM AND ENSEMBLES FORECAST THAT THE UPPER RIDGE WILL CONTINUE TO ADJUST AND BECOME GRADUALLY FLATTER THROUGH THE PERIOD. THE CLOSED UPPER LOW OVER OUR SOUTHEAST WILL WILL OPEN UP BY SUNDAY NIGHT INTO MONDAY. THE EURO AND CANADIAN OPENS THE LOW BY MONDAY AFTERNOON. THE UPPER TROUGH WILL LIFT NORTHEAST OF THE REGION BY MONDAY NIGHT WHICH WAS SHADOWED BY THE EURO AND CANADIAN AS WELL. MOST OF THE GFS AND EURO ENSEMBLES HAVE THE CLOSED UPPER LOW AND PUSH IT AWAY FROM THE REGION BY MONDAY EVENING. AS WE GO INTO THE EARLY TO MIDDLE PORTION OF NEXT WEEK WE WILL GO BACK TO DIURNAL CONVECTION WITH THE FLAT UPPER RIDGE OVER THE REGION. AN UPPER TROUGH WILL DEVELOP EASTWARD THROUGH THE ROCKIES INTO THE PLAINS BY LATE WEDNESDAY INTO THURSDAY. THE EURO WAS A LITTLE FASTER AS THE GFS HAS SLOWED THE TRACK OF THIS FEATURE FROM WEDNESDAYS RUN. THIS WILL HELP TO SUPPRESS THE FLAT RIDGE BY THURSDAY EVENING AS THE UPPER TROUGH DEVELOPS OVER THE REGION BY LATE THURSDAY INTO FRIDAY. THIS WAS CONFIRMED BY THE GFS AND EURO ENSEMBLES. THIS COULD GIVE THE REGION SOME DECENT CHANCES OF RAIN FOR THURSDAY INTO FRIDAY. WE WILL GET SOME UPPER JET ENERGY COMING OUT OF SOUTH TEXAS ON WEDNESDAY WHICH WILL CROSS THE REGION FOR WEDNESDAY THROUGH FRIDAY. THIS JET ENERGY WILL BE ENHANCE WITH THE UPPER TROUGH DEVELOPING FOR THURSDAY INTO FRIDAY. THIS COULD ENHANCE OUR CHANCES OF STRONG STORMS FOR THE MIDDLE TO LATER PORTION OF THE WORK WEEK. THE GFS ENSEMBLES WERE IN AGREEMENT...WHILE THE EURO AND ITS ENSEMBLES SHOWED WEAKER JET FLOW OVER THE REGION. AS FAR AS POPS ARE CONCERNED MADE SOME MINOR ADJUSTMENTS TO MEX POPS...ESPECIALLY WITH THE CLOSED UPPER LOW FOR SUNDAY AND THE JET SEGMENT ENHANCING CHANCES OF RAIN FOR THE MIDDLE TO LATER PART OF NEXT WEEK. AS FAR AS TEMPS ARE CONCERNED MADE SLIGHT ADJUSTMENTS TO MEX...MOS AND MEN GUIDANCE. GOING GENERALLY WITH LOWS FROM MAINLY THE MIDDLE 60S TO THE LOWER 70S AS WELL AS HIGHS FROM THE UPPER 80S TO LOWER 90S. THE EXCEPTION WAS HIGHS FOR SUNDAY IN THE MID TO UPPER 80S WITH THE CLOSED UPPER LOW. /17/ .AVIATION... ISOLATED TO SCATTERED SHOWERS/TSTMS LATE THIS AFTN AND EARLY EVNG WILL DIMINISH FOR THE OVERNIGHT...THEN THEY WILL REDEVELOP WITH DAYTIME HEATING SATURDAY BEFORE FIZZLING OUT AGAIN SATURDAY EVNG.
