&& .SHORT TERM /6 AM THURSDAY MORNING THROUGH FRIDAY NIGHT/... ON THURSDAY...HIGH PRESSURE WILL BUILD ACROSS THE SOUTHERN GREAT LAKES. MEANWHILE...THE STALLED AND WEAK FRONT WILL BE LOCATED AROUND THE OHIO RIVER. THERE IS ENOUGH WEAK FORCING AND INSTABILITY ACROSS THE SOUTH TO KEEP SLIGHT CHANCE POPS FOR THURSDAY AFTERNOON. EXPECT THE NORTH TO BE DRY AS THEY WILL BE CLOSER TO THE HIGH. TEMPERATURES SHOULD WORK INTO THE LOWER TO MID 80S. THE HIGH WILL SLIP OFF TO THE EAST THURSDAY NIGHT. THIS WILL BEGIN THE TRANSITION TO SOUTHERN FLOW AND A SLOW GRADUAL INCREASE OF LOW LEVEL MOISTURE. LOWS WILL FALL INTO THE 60S. FOR FRIDAY INTO FRIDAY NIGHT A H5 TROUGH WILL SWING THROUGH THE NRN PLAINS INTO THE GREAT LAKES. THIS WILL COMBINE WITH THE INCREASING MOISTURE TO PROVIDE A GOOD ENVIRONMENT FOR SCATTERED THUNDERSTORMS TO DEVELOP. HIGHS FRONTAL SHOULD MAKE THE MID 80S FOR MOST LOCATIONS. && .LONG TERM /SATURDAY THROUGH WEDNESDAY/... PERIOD STARTS WITH APPROACH OF COLD FRONT IN WARM AND HUMID AIR MASS. EXPECT CONVECTION FOR SATURDAY MAINLY IN THE AFTERNOON AND EVENING. WILL GO LIKELY POPS FOR NOW BUT COVERAGE COULD WARRANT EVEN HIGHER POPS.
