Strong storms possible Sunday evening in South-Central Pennsylvania
Isolated storms may develop between 4 p.m. and 6 p.m.
TEAM FORECAST WITH METEOROLOGIST MARYELLEN PANN. GOOD MORNING EVERYONE. WE’VE BEEN TALKING ABOUT THE THREAT FOR STORMS TODAY. THE STORM PREDICTION CENTER HAS HIGHLIGHTED THE ENTIRE STATE UNDER A SLIGHT RISK, WHICH IS A TWO ON A SCALE OF 1 TO 5, MEANING WE COULD HAVE SOME SCATTERED SEVERE STORMS. NOW, THE TIMING IS LATER TODAY. SO I WANT TO EMPHASIZE THAT MOST OF THE DAY IS GOING TO BE RAIN FREE AND JUST FINE TO GET OUT. ONCE WE GET TO 4:00, THEN WE START TO SEE A FEW STORMS POPPING UP. NOT EVERYBODY WILL SEE THEM, BUT BEYOND 6 P.M., THAT’S WHEN WE SEE A LINE OF STORMS ENTERING FROM THE WESTERN IN OUR WESTERN COUNTIES, AND THEN PUSHING OFF TO THE EAST. SO BETWEEN 6:00 AND 10 P.M., THOSE ARE GOING TO BE THE HOURS THAT WE HAVE THE BEST CHANCE FOR SEEING STRONG TO SEVERE STORMS. NOW, STORMS COULD STILL LINGER AFTER 10 P.M., BUT THEY WON’T BE SEVERE. IN FACT, WE’LL SEE STORMS TAPERING TO SHOWERS. AND THEN THIS ALL SHOULD GET OUT OF HERE BY 2:00 IN THE MORNING. TOMORROW MORNING, AS WE TAKE A LOOK AT THE STORM IMPACTS OR THE THREATS, WE’RE TALKING ABOUT, DAMAGING WINDS WILL BE THE MAIN THREAT. IT’S A MODERATE THREAT. LARGE HAIL IS A LOW THREAT. THERE COULD BE SOME FLASH FLOODING BECAUSE WE DO ANTICIPATE BRIEF HEAVY DOWNPOURS WITH THESE STORMS. FLASH FLOODING, THOUGH, IS GOING TO BE AN ISOLATED THREAT. AND I CAN’T RULE OUT A SPIN UP TORNADO OR TWO WITH THESE STORMS THAT THEY, AS THEY MOVE THROUGH THE AREA. BUT AGAIN, MOST OF THE DAY IS DRY. AS WE TAKE A LOOK AT PREDICTOR, YOU DON’T SEE ANYTHING. AND THEN WE GET TO 4:00. WE START TO SEE SOME STORMS COMING IN FROM THE WEST. NOW OTHER MODELS, OTHER HIGH RESOLUTION MODELS THAT I HAVE BEEN LOOKING AT, THEY’VE BEEN BOUNCING ALL OVER THE PLACE SINCE YESTERDAY, POPPING UP ISOLATED STORMS AHEAD OF THE FRONT. AND IT DEPENDS ON AN AREA OF LOW PRESSURE TO OUR SOUTH. IT’S CALLED A LOW AND WHERE THAT TRACKS AND DEVELOPS COULD TRIGGER THOSE ISOLATED STORMS. BUT AS I MENTIONED, ONCE WE GET BEYOND 6:00, WE START TO SEE THE LINE AHEAD OF THE COLD FRONT COMING THROUGH. YOU SEE THE DARK COLOR REDS. THAT’S WHERE WE COULD SEE THOSE HEAVY BURSTS OF RAINFALL. AND THAT COULD LEAD TO SOME FLASH FLOODING THAT WILL CONTINUE UNTIL 8:00. AND THEN WE’RE LEFT WITH JUST SOME SPOTTY STORMS AND SHOWERS FOR THE REST OF THE NIGHT UNTIL ABOUT 2 A.M. YOUR NEWS EIGHT STORM TEAM FORECAST TODAY, THOUGH LOW 70S AROUND 9:00. LATE DAY STORMS. OTHERWISE, IT’S DRY UNTIL 4:00, 6:00. HIGHS IN THE UPPER 80S AND WE’RE IN THE UPPER 70S AT 8:00. STORMS. SHOWERS COME TO AN END. DECREASING CLOUDS TONIGHT, DROPPING HUMIDITY. TEMPERATURES WILL FALL TO THE LOW 60S. AND TOMORROW IS GOING TO BE A GORGEOUS DAY, PARTLY TO MOSTLY SUNNY SKIES, COMFORTABLE AND COOLER. A LITTLE BREEZY. HIGHS ONLY IN THE MID 70S AND YOUR WEATHER AND HEALTH CHECK. TREE AND GRASS POLLEN CONTINUE. MODERATE AIR QUALITY IS MODERATE FOR PARTICULATES AND THE UV INDEX IS HIGH WITH A BURN TIME OF 25 MINUTES. WE HAVE TEMPERATURES MAINLY IN THE 60S ACROSS THE AREA. SELINSGROVE 5870 IN GETTYSBURG AND DEW POINTS RIGHT NOW UPPER 50S TO NEAR 60 DEGREES. SO THAT’S ACTUALLY FEELING SOMEWHAT COMFORTABLE. OUR FRONT, STILL WELL OFF TO THE WEST, HASN’T EVEN MOVED INTO THE OHIO VALLEY YET, SO WE ARE QUIET HERE LOCALLY. AND AGAIN, AS WE TAKE A LOOK AT PREDICTOR, MOST OF THE DAY IS QUIET. SO GET OUT AND ENJOY IT. YOU’LL JUST NOTICE THE HEAT AND THE HUMIDITY INCREASING. SO AS WE GO THROUGH THAT 4 TO 8:00 HOUR, YOU COULD SEE THOSE STORMS AROUND 8:00 IN OUR EASTERN AREAS. AND THEN STARTING TO WRAP UP AROUND HERE, AND THE FRONT MOVES THROUGH TOMORROW, LEADING TO LESS HUMID CONDITIONS. A NORTHWESTERLY WIND WITH PARTLY TO MOSTLY SUNNY SKIES AND THEN HIGH PRESSURE STILL IN CONTROL ON TUESDAY, KEEPS THAT COMFORTABLE WEATHER AROUND ONE MORE DAY BEFORE STORM CHANCES RETURN AND TEMPERATURES HEAD BACK TO THE 80S. SO MID 70S TOMORROW, UPPER 70S AND PLEASANT ON TUESDAY, LOW 80S WEDNESDAY AND THEN MID 80S ON THURSDAY. THURSDAY’S THE DAY WE GOT TO WATCH. WE COULD HAVE SOME STRONG STORMS AGAIN WITH THE FRONT COMING
