Thursday marks 59th anniversary of highest temperature ever recorded in South-Central Pennsylvania IT IS 648. LET’S TALK ABOUT OUR SEVERE WEATHER RISK TODAY. IT IS VERY LOW IN THE SUSQUEHANNA VALLEY. I DO THINK WE’LL SEE. JUST A COUPLE OF SHOWERS, THUNDERSTORMS POPPING THIS AFTERNOON INTO THE EVENING, BUT THEY’RE GOING TO BE FEW AND FAR BETWEEN. A MUCH BETTER CHANCE OFF TO OUR NORTH AND EAST, WHERE THERE’S A SLIGHT RISK OF SEVERE WEATHER, WHERE THE STORMS COULD BE A BIT STRONGER. WE’RE TALKING ABOUT DAMAGING WINDS, SOME HAIL AS OUR TWO PRIMARY CONCERNS. BUT LET ME SHOW YOU. HERE’S THE PREDICTOR ALL THE WAY THROUGH LUNCHTIME. IT’S DRY. IT’S QUIET AFTER LUNCHTIME. THERE COULD BE A FEW ISOLATED CELLS THAT POP UP, BUT I DO FAVOR THE EVENING FOR OUR BEST CHANCE. IF YOU DO SEE ANYTHING AT ALL AS A COLD FRONT APPROACHES. SO THERE WILL BE A BROKEN LINE OF SOME SHOWERS, THUNDERSTORMS, AND WE’RE JUST ON THE TAIL EDGE OF IT HERE IN THE SUSQUEHANNA VALLEY. MUCH HIGHER CHANCE OVER TOWARD THE POCONOS, NEW JERSEY, AND UP INTO THE NORTHEAST. IF YOU’RE HEADED THERE FOR YOUR HOLIDAY TRAVELS. BUT TODAY, FEW AND FAR BETWEEN IS THE MESSAGE. ISOLATED TO FEW STORMS. NEWS EIGHT STORM TEAM FORECAST CALLS FOR MOSTLY SUNNY SKIES THIS MORNING. NOT AS MUGGY. I THINK YOU’LL NOTICE THAT WHEN YOU STEP OUTSIDE. MATT SURE DID, HE SAID. HEY, IT FEELS PRETTY GOOD OUT HERE. YEAH, IT’S JUST A LITTLE BIT STICKY FOR THE AFTERNOON. 88 IS OUR TOP TEMPERATURE. AN ISOLATED STORM MAY BE AROUND AND WE’LL SEE A FEW THIS EVENING, BUT AFTER SUNSET, THOSE STORMS FIZZLE. SO IF YOU HAVE FIREWORKS THIS EVENING, YOU SHOULD BE A OKAY. TONIGHT, TEMPERATURES DROP DOWN INTO THE 60S. IT’S GOING TO BE MORE COMFORTABLE BEHIND THIS COLD FRONT. DEW POINTS ARE ON THE DECREASE. AND YOU KNOW WHAT THAT MEANS. TOMORROW IT’S GOING TO FEEL FANTASTIC. TOMORROW FOR THE FOURTH. IT’S MY PICK OF THE WEEK. IT’S A TEN OUT OF TEN. IT’S JUST GOING TO BE A GORGEOUS DAY. ABUNDANT SUNSHINE, LOW HUMIDITY, WARM AND PLEASANT WITH SEASONABLE HIGHS IN THE MID 80S. CURRENTLY WE HAVE 70 IN HARRISBURG AND GETTYSBURG AS OUR WARM SPOTS. PAIR OF SIXES IN LANCASTER AT 64 IN LEBANON AND A NICE START IN CHAMBERSBURG AT 68 DEW POINTS. MOST SPOTS IN THE LOW 60S. THAT’S WHAT WE LIKE TO SEE AT THIS TIME OF THE YEAR. AND WHEN WE DROP INTO THE 50S LIKE TOMORROW, THAT IS A REAL TREAT. SO TOMORROW IS GOING TO BE THE MOST COMFORTABLE DAY IN THE ENTIRE TEN DAY FORECAST. WEATHER IN HEALTH UPDATE. WE HAVE LOW MOLD SPORES, LOW POLLEN LEVELS AND MODERATE AIR QUALITY. TODAY, UV INDEX IS QUITE HIGH, SO IF THE KIDS ARE HITTING THE POOL TODAY, MAKE SURE YOU REAPPLY THAT SUNBLOCK A BURN TIME OF JUST 20 MINUTES. ONE COLD FRONT OFFSHORE. VERY WELL DEFINED HERE. ANOTHER ONE UP IN THE GREAT LAKES. THAT’S THE FRONT THAT DROPS IN THIS EVENING, TRIGGERING OUR SLIM CHANCE OF SOME SHOWERS AND THUNDERSTORMS. SO MOST OF THE STORM ACTION IS GOING TO BE OFF TO OUR NORTHEAST, BUT WE STILL COULD GET CLIPPED WITH A FEW HERE IN THE SUSQUEHANNA VALLEY. THEY’RE NOT GOING TO BE ANYTHING LIKE WE SAW EARLIER IN THE WEEK. WE JUST DON’T HAVE THE MOISTURE AVAILABLE. AND THESE STORMS ARE GOING TO BE ON THE MOVE. SO NOT A REPEAT OF THAT BY ANY MEANS. HERE COMES THE BIG BLUE H. WE LOVE IT. ON THE 4TH OF JULY, WINNER OF A FORECAST WALL TO WALL SUNSHINE HERE. JUST A GORGEOUS DAY. AND THEN HIGH PRESSURE SITS OFF TO OUR SOUTHEAST ON ON SATURDAY. AND THAT’S GOING TO GIVE US A SOUTHERLY WIND HELPING TO BOOST TEMPERATURES AND HUMIDITY VALUES. YOU KNOW IT COULDN’T LAST TOO LONG. SATURDAY IT WILL BE A BIT STICKY WITH A HIGH OF 88. SUNDAY IS HOT AND HUMID WITH A HIGH OF 90. WE GO WITH 92 ON MONDAY AND INCREASED STORM CHANCES NEXT WEEK, AS A FRONT DROPS IN TUESDAY
