Hot & humid before Wednesday rain

TONIGHT IN REGENT SQUARE KALEA GUNDERSON. PITTSBURGH’S ACTION NEWS FOUR. BACK NOW WITH PITTSBURGH’S ACTION, WEATHER AND CHIEF METEOROLOGIST MIKE HARVEY. AND NO ONE’S COMPLAINED ABOUT RAIN OR COLD WEATHER TODAY. NOT TODAY. VERY WARM OUT THERE TODAY. 89 DEGREES FOR YOUR HIGH TEMPERATURE IF YOU LIKE IT. WELL, TOMORROW WE’RE GOING FOR AROUND 89 DEGREES AS WELL. SUMMER LIKE SURGE CONTINUES INTO TOMORROW. THEN ON WEDNESDAY WE HAVE RAIN AND STORMS THAT WILL BE MOVING IN AND IMPACT DAY ON WEDNESDAY. AND THEN WE GO INTO MEMORIAL DAY WEEKEND AND WE WILL HAVE A CHANCE OF SHOWERS EACH DAY, SATURDAY, SUNDAY AND MONDAY. SO RIGHT NOW, STILL VERY WARM OUT THERE. 86 DEGREES, MONROEVILLE, GREENSBURG AT 88. UNIONTOWN AT 87. ALSO 87 IN BEAVER. MID 80S FOR CRANBERRY AND BUTLER NEW CASTLE AT 85. ALSO 85 IN CLARION. SO VERY WARM OUT THERE RIGHT NOW AS WE GO INTO TOMORROW MORNING, A VERY MILD START TO THE DAY, WE’RE ONLY GOING TO DROP DOWN TO AROUND 70 DEGREES FOR YOUR LOW TEMPERATURE. NORMAL HIGH THIS TIME OF YEAR 72. SO OUR LOW WILL BE LIKE THE HIGH TEMPERATURE. WE’LL TAKE IT RIGHT BACK UP TO THE UPPER 80S. FOR TOMORROW. WE’LL HAVE SUNSHINE THROUGH THE DAY, PARTLY CLOUDY SKIES AS WE HEAD THROUGH THE DAY. AND THEN AS WE GET LATE IN THE DAY, WE’LL HAVE A CHANCE OF A SHOWER COMING IN VERY LATE, AND MOST OF THAT WILL BE UP TO THE NORTH AS WELL, AND THAT WILL BE JUST AHEAD OF THE SHOWERS. THE POTENTIAL FOR AN ISOLATED THUNDERSTORM ON WEDNESDAY, OUR IMPACT DAY, WE DRY IT OUT ON THURSDAY, BUT YOU CAN SEE HOW THE TEMPERATURES DROP OFF ON THURSDAY AND FRIDAY HIGH OF 69 DEGREES. FRIDAY WE HAVE A CHANCE OF SCATTERED SHOWERS IN THE AREA, AND THE RAIN CHANCES WILL CONTINUE AS WE GO INTO SATURDAY, SUNDAY AND FOR MEMORIAL DAY. EACH OF THOSE DAYS, WE WILL HAVE A HIGH TEMPERATURE THAT WILL BE IN THE 70S. SO WE DO HAVE SOME RAIN SHOWERS THAT ARE TRYING TO WORK TOWARDS US. AS YOU CAN SEE, VERY SLOWLY WORKING ACROSS OHIO, BUT ALSO LOSING STRENGTH AS IT GETS CLOSER TO US. THE BEST CHANCE OF SEEING SOME RAIN IS GOING TO BE UP TO THE NORTH, BUT SOME OF THIS COULD MAKE IT THROUGH, BUT CERTAINLY WILL BE REDUCED IN INTENSITY AS IT PUSHES THROUGH THE AREA LATE TONIGHT. TEN 11:00 WON’T LAST FOR VERY LONG. WE’LL GO INTO TOMORROW MORNING AND BE SEEING PARTLY CLOUDY SKIES THROUGH THE DAY. SO A GOOD DEAL OF SUNSHINE, MAYBE SOME SHOWERS UP TO THE NORTH AS WE GET LATER INTO TUESDAY AND THEN ON WEDNESDAY. THAT IS GOING TO BE OUR RAIN DAY. WE’LL HAVE RAIN SHOWERS AND THE POTENTIAL FOR ISOLATED THUNDERSTORMS AS WE HEAD THROUGH THE DAY. HERE’S 3:00 WITH THOSE STORMS MOVING THROUGH OR SHOWERS WITH ISOLATED STORMS MOVING THROUGH. AND HERE’S YOUR THURSDAY. WE GET
