Severe thunderstorm warning issued for several South-Central Pennsylvania counties
I’M JACKSON KURTZ IN HANNIBAL, MISSOURI. NOW, THE ALERT DAY FORECAST FROM THE WGAL NEWS EIGHT STORM TEAM. GOOD EVENING EVERYONE. A SEVERE THUNDERSTORM WATCH IS NOW IN EFFECT FOR THE ENTIRE SUSQUEHANNA VALLEY HERE UNTIL 10 P.M. AND THAT’S BECAUSE WE’RE WATCHING THOSE STRONG STORMS OFF TO THE WEST THAT WILL EVENTUALLY MOVE IN. HERE’S A LOOK AT STORM RADAR NETWORK. IT’S QUIET RIGHT NOW. THIS IS THE OPPORTUNITY TO GET OUTSIDE. DO ANYTHING YOU NEED TO DO OUTSIDE WITHIN THE NEXT HOUR TO HOUR AND A HALF, BECAUSE YOU CAN SEE THEY HAVE SEVERE THUNDERSTORM WARNINGS ALREADY UP THERE TO JUST OUTSIDE OF ALTOONA AND ALONG I-99. THIS LINE WILL EVENTUALLY PUSH INTO THE SUSQUEHANNA VALLEY AND COULD PRODUCE SOME GUSTY WINDS, MAYBE SOME DAMAGING WINDS AS WE GO THROUGH THE EVENING ACROSS THE AREA. SO JUST KEEP THAT IN MIND. HERE’S A LOOK AT THE IMPACTS. AGAIN, OUR DAMAGING WIND THREAT IS MODERATE. LARGE HAIL IS LOW. SOME OF THESE STORMS ARE GOING TO PRODUCE LOTS OF HEAVY RAIN AND SOME GULLEY WASHERS WITH IT. AND THAT IS GOING TO ALSO POTENTIALLY DO A LITTLE BIT OF PONDING ON THE ROADWAYS. SO THERE’S A LOW FLASH FLOODING THREAT AS WELL AS THESE STORMS ROLL ON THROUGH. SO IT’S SOMETHING THAT JUST TO BE AWARE OF BETWEEN NOW AND ABOUT 10:00 TONIGHT. ONCE WE GET TO 10:00, THE STORMS WILL BE ENDING. AND THEN IT’S JUST A WARM, MUGGY NIGHT WITH SOME PATCHY FOG DEVELOPING HERE AFTER MIDNIGHT TONIGHT. BUT FOR YOUR WEATHER PLANNER, WE’RE GOING TO GO FROM THE 80S ONLY DOWN TO 72 FOR THAT OVERNIGHT LOW. SO IT’S GOING TO BE A WARM MUGGY NIGHT OVERNIGHT TONIGHT. TOMORROW WE’RE LOOKING AT HIGH AROUND 90. PARTLY SUNNY WITH SCATTERED SHOWERS AND THUNDERSTORMS EXPECTED. ONCE AGAIN WE’RE GOING TO BE REPEATING THE ENTIRE THING AS WE HEAD INTO YOUR FRIDAY. RIGHT NOW THOUGH, YOU STEP OUTSIDE. IT IS HOT. FEELS LIKE 101 DEGREES IN HARRISBURG. SAME THING IN LANCASTER. 108. THAT FEELS LIKE TEMPERATURE IN LEBANON. FEELS LIKE 102 IN CARLISLE, 101 IN LEWISTOWN IN 98 IN CHAMBERSBURG. THIS IS WHY YOU HAVE THAT HEAT ADVISORY THAT’S IN EFFECT FOR PARTS OF DAUPHIN, LEBANON, LANCASTER, YORK, CUMBERLAND AND ADAMS COUNTY. THAT GOES TILL 8:00 ON FRIDAY. SO HERE’S A LOOK AT THE PREDICTOR. YOU CAN SEE THE STORMS THERE AGAIN JUST OUTSIDE ALTOONA. HERE’S THE MODELS AT LEAST INITIALIZING PRETTY WELL AT THIS POINT. AS IT COMES ON IN, WE WILL BE WATCHING FOR SOME SHOWERS AND THUNDERSTORMS TO DEVELOP ONCE AGAIN ACROSS THE SUSQUEHANNA VALLEY AS WE HEAD INTO THE LATER PART OF THIS EVENING. BUT BY 10:00 IT IS OUT OF HERE. AS WE HEAD INTO YOUR FRIDAY, WE START OFF DRY. PLENTY OF SUNSHINE, BUT WE WILL SEE SOME MORE SHOWERS AND STORMS DEVELOP AS A COLD FRONT COMES THROUGH TOMORROW, LATE AFTERNOON AND EVENING. ONCE AGAIN, ONCE THE STORMS ARE OUT OF HERE, WE WILL ACTUALLY GET A LITTLE BIT OF A BREAK ON SATURDAY. HIGH PRESSURE MOVES IN FROM THE WEST THAT SHOULD USHER IN SOME MORE COMFORTABLE CONDITIONS FOR THE START OF THE WEEKEND. BUT FOR THE SEVERE WEATHER THREAT TOMORROW, FROM 3 TO 10 IN THE AFTERNOON AND EVENING, WE NEED TO WATCH AGAIN FOR SOME SCATTERED SHOWERS AND THUNDERSTORMS THAT COULD PRODUCE DAMAGING WINDS, LARGE HAIL AS WELL AS HEAVY RAIN. IN ADDITION TO THAT, IT’S GOING TO BE ANOTHER HOT AND HUMID DAY. IN FACT, I THINK IT’S GOING TO BE THE HOTTEST DAY HERE. TEMPERATURES GETTING AROUND 9092, BUT FEELING LIKE 100, 102 IN THE AFTERNOON ACROSS PARTS OF THE AREA. SO IT’S GOING TO BE ANOTHER HOT DAY ON YOUR FRIDAY. BUT AS I MENTIONED, SATURDAY’S STILL WARM. IT’S 88 DEGREES, STILL HOT, BUT IT’S NOT GOING TO BE AS HUMID. SO THAT’S GOING TO BE THE WORLD OF THE DIFFERENCE ON SATURDAY. SUNDAY FOR THE SECOND HALF OF THE WEEKEND, MOST OF THE DAY IS DRY, BUT LATE AFTERNOON AND EVENING. ONCE AGAIN, YOU’RE GOING TO WATCH FOR SHOWERS AND THUNDERSTORMS AS ANOTHER SYSTEM PULLS ON THROUGH AND COULD PRODUCE SOME STRONG THUNDERSTORMS. ONCE AGAIN, IT LOOKS LIKE A LITTLE BIT OF A LINE TRIES TO FORM RIGHT OVER THE SUSQUEHANNA VALLEY, IN FACT. AND AS THAT HAPPENS, COULD PRODUCE SOME GUSTY WINDS AND HEAVY RAIN TO END THE WEEKEND. BUT AGAIN, THAT’S MORE LATE SUNDAY AFTERNOON AND EVENING. SUNDAY MORNING IS GOING TO BE FINE IF YOU WANT TO DO ANYTHING OUTSIDE SUNDAY MORNING, HAVE BRUNCH OUTSIDE, YOU’LL BE ABLE TO DO SO WITHOUT ANY ISSUES AS THOSE STORMS WILL BE LATER IN THE DAY. BUT HERE’S A LOOK AT THE TEN DAY FORECAST. WE HAVE THE HEAT, HUMIDITY AND STORMS FOR YOUR FRIDAY. AND THEN AGAIN, A LITTLE BIT OF A BREAK THERE SATURDAY BEFORE WE GET THOSE EVENING STORMS SUNDAY TO END THE WEEKEND, WE DRY THINGS OUT AND IT’S MORE COMFORTABLE MONDAY. SAME THING ON TUESDAY. MAYBE AN ISOLATED SHOWER OR THUNDERSTORM THERE ON TUESDAY AFTERNOON, BUT IT WILL BE VERY HIT OR MISS 80 DEGREES. ON WEDNESDAY WE GET BACK TO 82 WITH THE CHANCE OF STORMS NEXT THURSDAY. AND GUYS, FOR THE FINAL COUPLE DAYS OF SPRING.
