THIS IS THE LAST DAY OF RATHER WARM TEMPERATURES AS A STRONG COLD  
FRONT WILL MOVE IN TONIGHT. BEFORE THAT OCCURS THERE IS A  
DIURNALLY DRIVEN LOW CLOUD DECK COVERING THE SOUTHERN HALF OF THE  
CWA. THIS MAY CONTINUE TO EXPAND NORTHWARD DUE TO SOUTHERLY LOW-  
LEVEL MOISTURE ADVECTION ASSOCIATED WITH TD CINDY. THE CLOUDS HAVE  
HELPED TEMPER THE TEMPERATURES IN THESE AREAS AND THE CLOUDS  
SHOULD MIX OUT NEAR SUNSET.  
 
THE FRONT IS PROGGED TO MOVE QUICKLY ACROSS THE REGION LATER  
TONIGHT. ALONG THE FRONT SCATTERED THUNDERSTORMS ARE EXPECTED TO  
DEVELOP. A FEW MAY BE STRONG, BUT NOT EXPECTING WIDESPREAD  
COVERAGE. THE BETTER CHANCES TO RECEIVE RAIN WILL BE ACROSS NORTH  
CENTRAL/NORTHEAST MO. THE ACTIVITY SHOULD CLEAR THE CWA SHORTLY  
AFTER SUNRISE. THE MOST NOTICEABLE RESULT WILL BE A COOLER AND  
LESS HUMID AIRMASS. VERY COOL TEMPERATURES, BY LATE JUNE MEASURES,  
ARE IN-STORE FOR THE WEEKEND AND THE START OF NEXT WEEK WITH  
HIGHS IN THE 70S.  
 
LOOKING PAST MONDAY, THERE ARE NO CLEAR SIGNALS FOR WIDESPREAD PRECIP  
UNTIL MID/LATE WEEK. TEMPS WILL SLOWLY MODIFY TO NEAR NORMAL (MID-  
80S).

THE MAIN IMPACT FOR THIS PERIOD WILL BE A LINE OF SHOWERS WITH  
EMBEDDED THUNDERSTORMS THAT WILL PUSH THROUGH JUST AFTER MIDNIGHT  
BEHIND AN APPROACHING COLD FRONT. CURRENTLY VCTS HAS BEEN USED TO  
SHOW THE THUNDERSTORM THREAT BUT THIS CAN BE UPGRADED AS  
CONFIDENCE IMPROVES ON TIMING. THE CURRENT TAF HAS VFR CONDITIONS  
BUT MULTIPLE FORECAST MODELS ARE INDICATED A PERIOD OF MVFR AND  
POTENTIAL IFR CEILINGS RIGHT ALONG THE BACKSIDE OF THE FRONTAL  
BOUNDARY AS IT PASSES. CURRENTLY NO LOWER CEILINGS HAVE DEVELOPED  
ALONG THE BOUNDARY AND WITH THIS UNCERTAINTY THE MVFR CEILINGS  
HAVE BEEN LEFT OUT FOR NOW. THE LOW CLOUDS SHOULD CLEAR OUT  
QUICKLY IN THE EARLY MORNING WITH A DRY NORTHERLY FLOW IN PLACE BY  
THE END OF THE TAFS.
