WILL NEED TO UPDATE FORECAST ONCE THE WATCH EXPIRES HOWEVER NO OTHER CHANGES APPEAR TO BE NEEDED AT THIS TIME. ARS && .PREV DISCUSSION... /ISSUED 326 PM CDT SAT MAR 27 2010/ A COUPLE OF ISSUES TO DEAL WITH THIS AFTERNOON...THE WINDS AND THE DEVELOPING STORMS. THE WINDS ARE JUST BELOW WIND ADVISORY CRITERIA AND EXPECT THEM TO STAY THERE WITH THE OCCASIONAL SITE GOING ABOVE 25 MPH FOR A HOUR OR TWO BEFORE FALLING BACK DOWN TO LESS THAN 25 MPH. GUSTS WILL BE STRONG. THE DEVELOPING STORMS ARE FROM A STACKED SURFACE LOW AND UPPER LOW THAT ARE SLOWLY MOVING EAST. THEY SHOULD BE NEAR THE MISSOURI BOOTHEEL BY SUNDAY MORNING. THE LOWS HAVE ALREADY STARTED TO INITIATE SOME THUNDERSTORMS SOUTHEAST OF THE LOW CENTERS. THIS AREA IS EXPECTED TO MOVE INTO THE MID-SOUTH THIS EVENING. SOME STRONG THUNDERSTORMS CAN BE EXPECTED. MODELS STILL INDICATE MUCAPES NEAR 600 J/KG AS A SQUALL LINE MOVES ACROSS THE REGION TONIGHT. THE LATEST MODELS INDICATE THAT THERE IS SOME WEAKENING OF THE INSTABILITY AS THE NIGHT PROGRESSES...ALSO THE STRONG JET ASSOCIATED WITH THE LOW WILL MOVE THE STORMS WELL AWAY FROM THE CENTER OF THE LOW WHICH IS PROVIDED COOL AIR ALOFT AND MAKING FOR AN UNSTABLE SOUNDING. THE LOWS WILL SLOWLY MOVE TO THE EAST HOWEVER...BRINGING THE AREA SOME UNSETTLED WEATHER FOR THE REST OF THE WEEKEND AND INTO MONDAY. THE MODELS AGREE THE REST OF THE WEEK SHOULD BE MILD WITH TEMPERATURES NEAR NORMAL AND DRY WEATHER. THE NEXT STORM SYSTEM MOVES THOUGH NEXT WEEKEND. EARLIER MODELS INDICATED IT WOULD BE SATURDAY...LATEST MODELS SEEMS A LITTLE SLOWER. TLSJR && .AVIATION... 06Z TAF CYCLE LINE OF SHOWERS AND THUNDERSTORMS MOVING EAST ACROSS THE MIDSOUTH IS ON SCHEDULE...AT 05Z THE LINE WAS MOVING EAST OF KMEM AND APPROACHING KMKL. SHOWERS AND THUNDERSTORMS ARE EXPECTED TO AFFECT KMKL UNTIL 07Z...AND KTUP UNTIL 09Z. WIND GUSTS TO BETWEEN 30 AND 40 KTS ARE POSSIBLE WITH THE LINE OF STORMS. OTHERWISE MVFR CEILINGS WILL OVERSPREAD THE MIDSOUTH FROM THE NORTHWEST OVERNIGHT AND CONTINUE DURING THE DAY SUNDAY WITH LINGERING SHOWERS POSSIBLE. CLOUDS ARE EXPECTED TO LIFT TO VFR AT KJBR AROUND 29/00Z AND AT KMEM AROUND 29/03Z. WIND GUSTS WILL DIMINISH WITH PASSAGE OF THE LINE OF THUNDERSTORMS. WINDS HAVE TURNED AROUND TO THE SE OR E BEHIND THE LINE OF CONVECTION. EXPECT THIS TREND TO BE TEMPORARY AS WINDS SHOULD TURN BACK AROUND TO THE SW. SW WINDS 10-15 KTS WILL BECOME MORE WESTERLY AFTER 18Z...THEN NW AFT 29/00Z. JCL/KRM && && .PRELIMINARY POINT TEMPS/POPS...
