Impact Day: Scattered afternoon strong thunderstorms for western PA

Cool Change Ahead To Start The Week
Turning Brisk and Colder Sunday and Monday
WEEK FOR THE FORESEEABLE FUTURE. TIME NOW FOR ANOTHER LOOK AT WEATHER. AND IT IS AN IMPACT DAY. JILL, WHAT SHOULD WE EXPECT? WELL, WE’RE SEEING MORE STORMS THROUGH THE AFTERNOON, SO THINGS ARE JUST FINE RIGHT NOW. IF YOU’VE GOT SOME RUNNING AROUND TO DO, WE’VE GOT SOME LITTLE LEAGUE GAMES TODAY. THINGS SHOULD BE JUST FINE. BUT AFTER 3:00, SHOWERS AND THUNDERSTORMS WILL SHOW UP. THEY’LL LAST THROUGH ABOUT 7 P.M. WITH STILL MORE RAIN ON TAP AS WE GO THROUGH THE NIGHT. FEELING VERY SUMMERLIKE TODAY. NOT SO MUCH TOMORROW. BLUSTERY CONDITIONS WITH A FEW SHOWERS, MAYBE EVEN A FLURRY OR TWO. THE FARTHER NORTH YOU ARE BY THE END OF THE DAY SUNDAY. FOR THE TIME BEING TODAY THOUGH, SCATTERED THUNDERSTORMS. AREA ONE IS EVERYBODY IN THAT YELLOW SHADING AS WE WORK THROUGH THE AFTERNOON. DAMAGING WINDS WILL BE OUR PRIMARY THREAT, BUT ALSO CAN’T RULE OUT SOME LARGE HAIL, LOCALIZED FLASH FLOODING, AND SIMILAR TO WHAT WE DEALT WITH A COUPLE DAYS AGO, WE MAY SEE A FEW TORNADO WARNINGS FOR SOME BRIEF SPIN UPS IN YOUR 4-DAY PLUS 4 MORE FORECAST VERY SUMMERLIKE TODAY 84 OUR HIGH TEMPERATURE. THOSE SCATTERED STORMS AFTER 3 P.M. MORE RAIN TONIGHT AS THIS IS WAY BACK IN THE TEMPERATURE DEPARTMENT. 53 ARE HIGH. TO WRAP UP THE WEEKEND. MEANWHILE MONDAY EVEN COLDER. WE’RE NOT EVEN GOING TO MAKE IT OUT OF THE 40S. GOOD NEWS THOUGH. TEMPERATURES ARE LOOKING UP AND IMPROVING ALL IN TIME FOR THE START OF THE NFL DRAFT LATER ON IN THE WEEK. RIGHT NOW, 66 UNDER THE FILTERED SUNSHINE, WE WILL SEE MORE IN THE WAY OF CLOUDS AND SUNSHINE MIXING AS WE GO THROUGH THE START OF YOUR SATURDAY. HERE’S THE LATEST ROUND OF FUTURE CAST. YOU CAN SEE THAT LINE STARTING TO CLOSE IN ON WESTERN PA AS EARLY AS 3:00. THOSE OF YOU WEST OF THE CITY WILL BE FIRST TO BE HIT BY THE STORMS. WE’VE SEEN CONSISTENT FROM EACH MODEL RUN THAT A LOT OF THE STORM ACTIVITY LOOKS TO BE FROM ALLEGHANY COUNTY POINTS TOWARDS THE NORTH. THAT’S NOT TO SAY THAT THOSE OF YOU. WASHINGTON, WAYNESBURG, UNIONTOWN DON’T HEAR SOME OF THOSE RUMBLES OF THUNDER. FIND SOME GUSTY SHOWERS AND THUNDERSTORMS WORKING THROUGH WITH. JUST LOOKS LIKE A LOT OF THE INGREDIENTS ARE ON THE NORTHERN SIDE OF THAT LINE. THINGS BEGIN TO BREAK DOWN AS EARLY AS 7:00. SO REALLY A NARROW WINDOW FOR THOSE STORMS AS WE WORK THROUGH THE LATE AFTERNOON, BUT STILL DAMAGING WINDS COULD PACK QUITE A PUNCH ACROSS THE AREA. NOT QUITE JUST YET. WE WILL SETTLE DOWN FOR A LITTLE WHILE, BUT THEN AS WE GET CLOSER TO 11:00 MIDNIGHT, MORE AREA WIDE RAIN WILL BUILD IN. THAT WILL HANG WITH US FOR SEVERAL HOURS THROUGH THE START OF THE DAY ON SUNDAY. LET’S GO THROUGH THE DAY TOMORROW WITH TEMPERATURES ALSO PLOTTED HERE. MUCH COOLER. NO MORE 80S. IN FACT, WE’RE ONLY IN THE 40S FOR THE BULK OF THE DAY. TOMORROW, SOME SPOTTY LAKE EFFECT RAIN SHOWERS WILL SHOW UP. COULD GET CHILLY ENOUGH EVEN INTO THE EVENING HOURS THAT WE COULD CATCH A FEW STRAY FLAKES. JUST WRAPPING UP THE WEEKEND, NOT TALKING ABOUT FLAKES, BUT INSTEAD SOME FROST BOTH MONDAY AND TUESDAY AS YOU’RE WAKING UP. SO GOOD IDEA TO THINK AHEAD. MAKE SOME PLANS TO BRING YOUR PLANTS INDOORS TO PROTECT. THOSE CROPS MAY ALREADY BE IN THE GROUND. WE DO GET A LOT OF SUNSHINE EARLY IN THE WEEK. NEXT RAIN CHANCE COMES IN ON WEDNESDAY. GOOD TIMING FOR US WITH EVERYBODY TRYING TO COME INTO TOWN FOR THE NFL DRAFT, WE DO LOOK TO STAY DRY FOR DRAFT WEEKEND. TEMPERATURES WILL BE IMPROVING MID 70S DURING THE DAY ON THURSDAY. SHOULD BE A REALLY NICE EVENING FOR THE FIRST ROUND OF PICKS ON THURSDAY. FRIDAY’S DRY ALL DAY. IT WILL BE NEXT SATURDAY. WE MAY HAVE TO MONITOR SOME RAIN CHANCES BUT THAT WILL BE IT FOR YOUR DRAFT WEEKEND. TODAY, THOUGH
