IMPACT: Storms may bring damaging winds, hail and isolated tornado risk to south-central Pennsylvania
GOOD MORNING. TODAY IS AN IMPACT DAY FOR SCATTERED STRONG TO SEVERE STORMS THIS AFTERNOON AND THIS EVENING. RIGHT NOW WE ARE SEEING A LITTLE BIT OF LIGHT RAIN BUT NOTHING SEVERE CURRENTLY OR FOR THE MORNING DRIVE. YOU CAN SEE SOME RAIN LIFTING TOWARD MIFFLIN JULIANA PERRY COUNTY GETTING CLIPPED WITH A FEW SHOWERS. SO WE WILL BE WATCHING THAT FOR YOU THIS MORNING. BUT HERE’S THE STORM PREDICTION CENTER OUTLOOK, INCLUDING MOST OF THE SUSQUEHANNA VALLEY IN A SLIGHT RISK OF SEVERE WEATHER TODAY. SO SCATTERED SHOWERS, THUNDERSTORMS, SECOND HALF OF THE DAY COULD PRODUCE DAMAGING WIND GUSTS AND HEAVY RAIN. AS OUR TWO PRIMARY THREATS. AND THERE COULD ALSO BE SOME ISOLATED HAIL OR A WEAK SPIN UP TORNADO, SO WE WON’T RULE THAT OUT. BUT DAMAGING WINDS AND HEAVY RAIN ARE GOING TO BE WHAT WE’RE LOOKING OUT FOR LATER TODAY. SO YOU CAN SEE HERE ON THE PREDICTOR DURING THE MORNING RUSH, THERE WILL BE SOME SHOWERS AROUND, BUT THOSE WON’T BE SEVERE. THE WINDOW OF OPPORTUNITY FOR SOME STRONGER STORMS OPENS AFTER 1:00 TODAY. AND I REALLY THINK WE SEE THE HIGHEST CHANCE COMING TOWARD DINNER TIME. SO HERE WE ARE AT 4:00, 5:00, 6:00. THAT’S WHEN SOME SCATTERED THUNDERSTORMS MOVE ACROSS THE AREA, AND THEN THEY HEAD OFF TO THE EAST. SO THINGS QUIET DOWN AFTER DARK TONIGHT. AND THEN WE’LL JUST SEE SOME SCATTERED SHOWERS. NOTHING SEVERE OVERNIGHT INTO EARLY TOMORROW MORNING. SO FOR OUR NEWS EIGHT STORM TEAM FORECAST TODAY WE HAVE CLOUDS TO START. FEELS FINE OUT THERE NOW, BUT HUMIDITY BUILDS THIS AFTERNOON AS A WARM FRONT LIFTS NORTH. AND THAT PROVIDES THE CHANCE FOR THOSE SCATTERED SHOWERS AND STORMS. SO IT’S NOT GOING TO BE RAINING ALL AFTERNOON OR ALL EVENING. THEY’LL BE DRY TIME OUT THERE AND THOSE THUNDERSTORMS WILL BE HIT OR MISS. VARIETY SO SCATTERED THROUGH THE AFTERNOON AND EVENING, TEMPERATURE WISE, WE GET UP TO 78 TONIGHT. STORMS ARE OUT OF HERE. THERE WILL BE SOME LINGERING SHOWERS, SOME PATCHY FOG. TEMPERATURES WILL BE MILD IN THE 60S AND TOMORROW SOME SHOWERS STILL POSSIBLE EARLY AS A COLD FRONT SLOWLY MOVES EAST. OTHERWISE WE’LL SEE MORNING CLOUDS THEN GRADUAL CLEARING IN THE AFTERNOON AND HUMIDITY WILL DROP. SO IT’S KIND OF A TRANSITION DAY TO GET US TO MORE COMFORTABLE WEATHER FOR MIDWEEK. ON WEDNESDAY. TEMPERATURE CHECK 63. IN LEWISTOWN WE HAVE 67 FOR CARLISLE AND GETTYSBURG, 63 IN LANCASTER AND YORK. OUR DEW POINTS FEELING FINE RIGHT NOW IN THE 50S, BUT THEY’RE GOING TO BE CLIMBING INTO THE MID 60S LATER TODAY, SO THAT WILL PROVIDE SOME FUEL, SOME ENERGY FOR THOSE STRONGER STORMS. WEATHER AND HEALTH CHECK. WE HAVE LOW LEVELS OF TREE AND GRASS POLLEN EXPECTED. OUR AIR QUALITY IS LOOKING GOOD. UV INDEX MODERATE WITH A BURN TIME OF 40 MINUTES. SO SOME SHOWERS RIGHT NOW MOVING THROUGH THE AREA AS THIS CLUSTER OVER OHIO AND INTO NEW YORK, WESTERN PENNSYLVANIA SLOWLY MOVES OFF TO THE EAST. BUT THERE IS AN AREA OF LOW PRESSURE BACK TOWARD INDIANA, AND THAT’S WHAT’S GOING TO COME THROUGH LATER TODAY. SO HERE’S WHAT THE PREDICTOR SHOWS. WE SEE SOME SCATTERED ACTIVITY THIS MORNING, NOT SEVERE. THEN THE SEVERE STORMS THIS AFTERNOON. AND THIS EVENING AFTER THEY MOVE THROUGH IT QUIETS DOWN. BUT WE STILL SEE SOME SCATTERED SHOWERS OVERNIGHT. A FEW LINGERING SHOWERS AS THE FRONT SLOWLY MOVES EAST TOMORROW MORNING. AND THEN WE SHOULD SEE THAT GRADUAL CLEARING, FALLING HUMIDITY BY TOMORROW EVENING. WEDNESDAY LOOKS FANTASTIC. IT’S MY PICK OF THE WEEK FOR YOU. IT’S LOOKING REALLY NICE. LOW TO MID 80S FOR HIGHS. LOW HUMIDITY LOCKED IN AND PLENTY OF SUNSHINE. SO HERE’S OUR PREDICTOR. ESTIMATED RAINFALL TOTALS. AND IT’S KIND OF HARD TO GIVE YOU RAINFALL TOTALS WHEN WE HAVE THOSE HIT OR MISS THUNDERSTORMS. BUT IF YOU’RE UNDER ONE OF THE HEAVIER THUNDERSTORMS TODAY, YOU COULD PICK UP A QUICK HALF INCH TO AN INCH OF RAIN. HERE’S THE TEN DAY FORECAST WE ARE LOOKING FOR 78 FOR THE HIGH TOMORROW, 84 ON WEDNESDAY. WE DO 86 ON THURSDAY WITH HUMIDITY BUILDING AND MAYBE A SHOWER OR THUNDERSTORM LATE IN THE DAY. FRIDAY AND SATURDAY WILL FEATURE SOME SCATTERED SHOWERS AND STORMS. AND THEN AS WE APPROACH NEXT WEEK, REGINA THAT WORD HUMID, HOT. THAT’S THAT’S BACK IN THE FORECAST. SO IT LOOKS LIKE WE FINALLY
