ISSUED AT 230 PM CDT MON AUG 20 2018  
 
BROKEN LINE OF THUNDERSTORMS ALONG A COLD FRONT, SOME WHICH MAY  
BE STRONG TO SEVERE AT TIMES, WILL CONTINUE TO WORK ACROSS THE MS  
RIVER INTO WRN KY/SW IN THIS EVENING. SHOULD BE SEEING INSTABILITY  
WANE OFF WITH LOSS OF ANY HEATING, WHICH THUS FAR HAS BEEN QUITE  
LIMITED OVER THOSE AREAS DUE TO DEBRIS CLOUDS FROM EARLY  
CONVECTION OFF TO THE SOUTH. THUS, DO NOT EXPECT A BIG SEVERE  
RISK TO LAST MUCH PAST 02-04Z THIS EVENING.  
 
COLD FRONT SHOULD THEN CLEAR THE REGION TONIGHT, AND BRING MOST  
STORM CHANCES TO AN END FROM WEST TO EAST. HOWEVER, THE MID LEVEL  
TROF AXIS MAY TAKE A BIT LONGER TO THE PASS OFF TO THE EAST.  
THEREFORE, NOT SURE WE WILL SE MUCH IN THE WAY OF SUNSHINE AT MOST  
LOCATIONS TUESDAY, AND MAY EVEN SEE A FEW SHOWERS SW IN/NW KY  
DURING THE DAY. WITH COLDER TEMPS ALOFT, CANNOT RULE OUT AN  
ISOLATED THUNDERSTORM OR TWO.  
 
THEREAFTER, EXPECTING REALLY NICE LATE SUMMER CONDITIONS TO TAKE  
OVER AS SURFACE HIGH PRESSURE PRESSES SOUTHEAST INTO THE MIDWEST  
BY WEDNESDAY. IN FACT, TEMPERATURES WILL LIKELY STAY IN THE 70S  
TO NEAR 80 MOST LOCATIONS, WITH LOWERING HUMIDITY LEVELS. MOTHER  
NATURE WILL PROVIDE SOME FREE AIR CONDITIONING WEDNESDAY NIGHT AS  
TEMPS FALL OFF INTO THE MID 50S AND UPPER 50S.  
   
LONG TERM
 
(THURSDAY THROUGH MONDAY)  
ISSUED AT 230 PM CDT MON AUG 20 2018  
 
A RATHER QUICK RETURN TO HEAT AND HUMIDITY WILL OCCUR LATE THIS WEEK  
AND CONTINUE INTO EARLY NEXT WEEK. A LARGE SUBTROPICAL RIDGE WILL  
BECOME ESTABLISHED ACROSS THE SOUTHERN TWO-THIRDS OF THE NATION OVER  
THE WEEKEND. THIS HIGH WILL BRING THE HEAT AND HUMIDITY. MAINLY DRY  
CONDITIONS ARE EXPECTED, HOWEVER SLIGHT CHANCES OF MAINLY DIURNAL  
CONVECTION WILL BE FORECAST.  
 
THURSDAY WILL BE THE LAST DAY OF THE PLEASANTLY WARM AND DRY  
CONDITIONS, WITH HIGHS AROUND 80. AS THE SURFACE HIGH MOVES TO THE  
EAST, HIGHS WILL WARM TO AROUND 90 OVER THE WEEKEND INTO EARLY NEXT  
WEEK. OVERNIGHT LOWS WILL CLIMB FROM THE UPPER 50S THURSDAY NIGHT TO  
THE LOWER 70S OVER THE WEEKEND.
