LATEST REGIONAL RADAR LOOP SHOWS DECAYING MCS MOVING THROUGH THE HEARTLAND LATE MORNING AND EARLY AFTERNOON. LIGHTNING CHART SHOWS A PERSISTENT DECREASE IN CONVECTION WITH TIME. SURFACE ANALYSIS SHOWS MID 70 DEWPOINTS AHEAD OF THE MCS WITH UPPER 60S TO AROUND 70 IN ITS WAKE. VISIBLE SATELLITE LOOP SHOWS ABUNDANT CLOUD COVER MOVING INTO THE QUAD STATE WHICH SHOULD NEGATE ANY NEED FOR HEAT ADVISORY TODAY. HEAVILY WEIGHTED THE 12Z NAM FOR THE FIRST 24 TO 48 HOURS. THIS IS DUE MAINLY TO THE FACT THAT THE NAM ADVERTISED THIS MCS ON YESTERDAYS RUNS. ALTHOUGH THE TIMING WAS A BIT SLOW...BY ABOUT SIX HOURS. IT STILL PICKED UP ON THE MCS LOCATION AND DIRECTION OF MOVEMENT. THUS ITS ADVERTISING A SIMILAR SCENARIO FOR MONDAY AND HAVE EMBRACED THIS SOLUTION. ALSO WITH FRONT MEANDERING JUST NORTH OF THE AREA MOST OF THE WEEK HAVE INTRODUCED OR MAINTAINED DAILY CHANCES OF TSRA UNTIL FRIDAY. MOST MODEL RUNS REFLECT THE AFOREMENTIONED PATTERN. HIGH PRESSURE AT THE SURFACE AND ALOFT RETROGRADES BACK INTO THE REGION FRIDAY...SUPPRESSING TSRA DEVELOPMENT. FINALLY TOOK THE PLUNGE AND INTRODUCED POPS FOR THE WEEKEND WITH THE BEST CHANCE APPEARING TO BE SUNDAY ATTM. THIS IS DUE TO THE HIGH PUSHING OFF THE TOWARD THE EAST COAST AND A WEAK FRONT MEANDERING ALONG THE NORTHERN PORTIONS OF THE FA. WILL CONTINUE TO FLIRT WITH HEAT ADVISORY CRITERIA THROUGH THE WEEK. HOWEVER INDICATIONS FOR NOW SUGGEST SLIGHTLY BELOW ADVISORY CRITERIA. SOUTHEAST MISSOURI WILL BE THE WARMEST MONDAY BUT SHOULD STAY JUST A FEW DEGREES BELOW ADVISORY. OTHERWISE ONLY MINOR TWEAKS TO CURRENT TEMPS FORECAST. && .AVIATION... WILL HAVE SOME FORM OF THUNDER AT EACH TAF SITE FOR A FEW HOURS THIS AFTERNOON AS THE MCS MOVES THROUGH. COULD SEE VERY BRIEF IFR CONDITIONS IN THE STRONGEST STORMS...BUT IN GENERAL FEEL THAT MVFR RAINS WILL BE THE DOMINANT IMPACT THROUGH THE PERIOD. WILL ALSO SEE A GUST 25 TO 35KTS AS THE LEADING LINE OF STORMS MOVES THROUGH THE REGION. SUSPECT THAT WINDS WILL TURN BACK TO THE SOUTH FAIRLY QUICKLY BEHIND THE MAIN LINE. WILL HAVE NO OTHER PRECIPITATION IN THE TAFS. SHOULD SEE VFR CONDITIONS BY 00Z AT ALL TAF SITES. MVFR FOG COULD DEVELOP IF WE CAN GO CLEAR AND CALM LATE TONIGHT. ALSO HAVE TO ACCOUNT FOR POTENTIAL MVFR/IFR CEILINGS ONCE AGAIN LATE TONIGHT AND MONDAY MORNING...MAINLY OVER WEST KENTUCKY. && .PAH WATCHES/WARNINGS/ADVISORIES... KY...NONE. MO...NONE. IL...NONE.
