.UPDATE...
ISSUED AT 930 PM CDT FRI APR 13 2012
SPENT EARLY PART OF SHIFT TRYING TO PIN DOWN AREA OF HEAVIEST
RAIN THREAT...AND BELIEVE THAT MOTHER NATURE HAS NOW SHOWED HER
HAND WITH THE EARLY EVENING CONVECTION THAT HAS BEEN MOVING FROM
SW MO INTO OZARKS AND PARTS OF CENTRAL MO. WITH PERSISTENT SW 850
FLOW PROGGED INTO THIS AREA OVERNIGHT BELIEVE THAT PRIMARY AXIS OF
SHOWER/THUNDERSTORM ACTIVITY WILL REMAIN FAIRLY ANCHORED OVER THIS
AREA....WITH 35-45KT SPEEDS AT LEAST PARTIALLY OFFSETTING ANY
TENDENCY FOR CONVECTION TO BECOME STRONGLY OUTFLOW DOMINATED. DUE
TO QUASI-STATIONARY NATURE OF CONVECTION AND WITH PWATS 1-1.5
INCHES HAVE GONE OUT WITH A FLASH FLOOD WATCH FOR CENTRAL AND EAST
CENTRAL MISSOURI...AND EXTREME SOUTHWEST ILLINOIS...THROUGH 10 AM
TOMORROW MORNING. CERTAINLY EXPECT THAT AREA/TIME MAY NEED TO BE
ADJUSTED LATER TONIGHT...BUT BELIEVE THIS SHOULD BE A DECENT FIRST START.

70S ACROSS SOUTHWEST MISSOURI. THE WARM FRONT IS FORECAST TO
SLOWLY LIFT ACROSS THE AREA OVER THE NEXT 24 HOURS AND AS IT
DOES...ANOTHER ROUND OF THUNDERSTORMS IS EXPECTED TO DEVELOP AND
MOVE ACROSS THE AREA. SOME CONCERN THAT LOCALLY HEAVY RAINFALL
WILL BE POSSIBLE LATE TONIGHT AND EARLY SATURDAY MORNING ACROSS

STORMS WITH AMPLE INSTABILITY BOTH AT THE SFC AND ALOFT AND
RELATIVELY STRONG SHEAR WITH A STRONG SWLY MID LEVEL JET MOVING
THROUGH THE AREA AHEAD OF THE APPROACHING 500 MB TROUGH. THE
PRECIPITATION SHOULD SHIFT E-SE OF OUR FORECAST AREA BY MON MRNG
WITH FAIRLY STRONG LOW LEVEL CAA BEHIND THE 850 MB TROUGH...AND
DRYING OF THE 850 MB/SFC DEWPOINTS BEHIND THE 850 MB TROUGH/SFC
COLD FRONT. COOLER TEMPERATURES...AT OR BELOW SEASONAL NORMALS CAN
