GOOD MORNING. HAPPY FATHER\u2019S DAY TO ALL THE DADS OUT THERE. GUESS WHAT? SUMMER OFFICIALLY ARRIVED THIS MORNING AT 4:24 A.M. AVERAGE HIGH TODAY 84. THE AVERAGE LOW IS 65. AND IT\u2019S A GREAT LOOKING START TO THE DAY WITH PLENTY OF SUNSHINE THIS MORNING. TEN DAY FORECAST SHOWS THAT WE\u2019LL SEE MOSTLY SUNNY SKIES WITH SOME HIGH CLOUDS LATER TODAY. HIGHS WILL TOP OUT AROUND 84 DEGREES, EXACTLY WHERE WE SHOULD BE. TOMORROW IS AN IMPACT DAY BECAUSE WE ARE TRACKING A SYSTEM THAT\u2019S GOING TO BRING US THE CHANCE FOR SHOWERS AND THUNDERSTORMS, AND SOME OF THOSE THUNDERSTORMS. AN ISOLATED CHANCE FOR SEVERE WEATHER TUESDAY. CLOUDS WILL DECREASE, HUMIDITY DECREASES. IT WILL BE BREEZY AND PLEASANT. HIGHS AROUND 80. LOW 80S ON WEDNESDAY WITH MOSTLY SUNNY SKIES. AND THE NEXT SHOWER AND STORM CHANCE WILL COME IN LATE ON THURSDAY. WE\u2019LL CONTINUE WITH THAT CHANCE ON FRIDAY HEADING INTO THE WEEKEND. STILL SOME QUESTION ON WHICH DAY HAS THE BEST CHANCE FOR SHOWERS AND STORMS. I THINK THERE\u2019LL BE PLENTY OF DRY HOURS AND WE\u2019LL CONTINUE TO ADJUST THIS FORECAST AS WE HEAD IN THE NEXT COUPLE OF DAYS, BUT TEMPERATURES PRETTY CLOSE TO WHERE WE SHOULD BE. AND THEN WE START TO SEE A WARM UP EARLY NEXT WEEK, POSSIBLY SOME 90S, RETURNING TO THE AREA AFTER WE HEAD ON TUESDAY. YOUR NEWS EIGHT STORM TEAM FORECAST FOR TODAY CALLS FOR MOSTLY SUNNY SKIES THIS MORNING AT 9:00. TEMPERATURES RIGHT AROUND 70. SUNSHINE AND SOME HIGH CLOUDS NOT AS BREEZY. 84. AND THIS EVENING WE\u2019LL SEE THOSE CLOUDS REALLY STARTING TO INCREASE ACROSS THE AREA OVERNIGHT. TONIGHT MOSTLY CLOUDY. THERE MAY BE A FEW SHOWERS VERY LATE TOWARDS THE MORNING HOURS SKIMMING THROUGH THE AREA. NOT EVERYBODY WILL SEE THEM. TEMPERATURES WILL BE SEASONABLE IN THE LOW 60S TOMORROW. WE\u2019VE GOT A FEW EARLY MORNING SHOWERS. AGAIN. NOT EVERYBODY WILL SEE THEM. AND THEN HEADING INTO THE AFTERNOON, THE EVENING WILL SEE SCATTERED SHOWERS AND ISOLATED SEVERE STORMS. POSSIBLE RAIN COULD BE HEAVY AT TIMES. TEMPERATURES WILL FALL INTO THE UPPER 70S FROM THE LAST COUPLE OF DAYS WE\u2019VE BEEN IN THE 80S. WE\u2019LL SEE THEM A LITTLE BIT COOLER TOMORROW. TODAY IN YOUR WEATHER AND HEALTH, CHECK TREE AND GRASS POLLEN CONTINUES ON THE MODERATE SIDE. AIR QUALITY IS GOOD AND THE UV INDEX IS HIGH. WITH THE BURN TIME OF ABOUT 20 TO 25 MINUTES. SO CERTAINLY WANT TO MAKE SURE THAT YOU HAVE THE SUNSCREEN. TEMPERATURES RIGHT NOW 52 IN LEWISTOWN, 54 IN SELINSGROVE. WE HAVE MID 50S IN YORK, 62 IN HARRISBURG, 61 IN GETTYSBURG, AND UPPER 50 THERE IN CHAMBERSBURG. SO WE HAD A SYSTEM THAT MOVED THROUGH, BROUGHT THOSE SHOWERS LAST EVENING, EVEN A RUMBLE OF THUNDER IN PARTS OF OUR NORTHWEST COUNTIES. BUT HIGH PRESSURE IS BUILDING IN KEEPING THINGS NICE AND QUIET TODAY. OUR NEXT SYSTEM COMES IN TOMORROW. WE\u2019LL TAKE A LOOK AT THAT ON OUR PREDICTOR. SO HIGH CLOUDS WILL DRIFT IN LATER TODAY, BUT STILL PLENTY OF SUNSHINE. AND THEN THEY REALLY THICKEN UP OVERNIGHT TONIGHT INTO TOMORROW MORNING. THIS PARTICULAR MODEL JUST HINTING AT A SHOWER, SOME OTHER DATA I\u2019M LOOKING AT SHOWS THERE COULD BE A FEW MORE SHOWERS IN THE AREA, BUT NOT EVERYBODY WILL SEE THEM HEADING INTO THE AFTERNOON. WE\u2019VE GOT A PRE-FRONTAL TROUGH COMING IN AND THEN AN ACTUAL FRONT THAT\u2019S ALSO GOING TO BE FOLLOWED WILL FOLLOW THAT PRE-FRONTAL TROUGH AND WE WILL SEE THAT CHANCE FOR SCATTERED SHOWERS AND EVEN SOME THUNDERSTORMS. IF YOU GET IN UNDER ONE OF THESE STORMS, IT HAS HAS THE POTENTIAL TO PRODUCE SOME HEAVY DOWNPOURS. LOOKS LIKE SHOWER CHANCES WILL CONTINUE UNTIL ABOUT MIDNIGHT AND THEN EVERYTHING MOVES ON OUT OF HERE TUESDAY. SETTING UP TO BE A REALLY NICE LOOKING DAY. WE ARE. OUTLOOK IN A MARGINAL RISK FOR ISOLATED SEVERE STORMS. THAT\u2019S A ONE. ON A SCALE OF 1 TO 5, A HIGHER THREAT DOWN TO THE SOUTH ACROSS MARYLAND AND PORTIONS OF D.C. WE ARE IN A SLIGHT RISK FOR EXCESSIVE RAINFALL. THAT MEANS WE WILL BE WATCHING OUT FOR THE POSSIBILITY OF FLASH FLOODING. RAIN AMOUNTS ANYWHERE FROM A QUARTER OF AN INCH UP TO AN INCH OR MORE IN SOME ISOLATED SPOTS. IF YOU GET IN UNDER ONE OF THESE, THUNDERSTORMS. QUICK LOOK AT YOUR TEN DAY FORECAST SHOWS TEMPERATURES IN THE LOW 80S TUESDAY AND WEDNESDAY. QUIET DAYS. WE\u2019RE DRY, PLEASANT, AND THEN STORM CHANCES RETURN TOWARDS THE END OF THE WEEK. TEMPERATURES STAYING PRETTY UNIFORM UNTIL WE GET INTO EARLY\n\t\t\t\t\t\t\t\t\t\t\t<\/p>\n<p>Storm threat makes Monday an Impact Day<\/p>\n<p>Rain chances increase overnight for South-Central Pennsylvania<\/p>\n<p>\t\t\t\t\t\t<img decoding=\"async\" src=\"https:\/\/www.newsbeep.com\/us-pa\/wp-content\/uploads\/2026\/01\/1769026991_958_wgal.png\" class=\"lazyload lazyload-in-view branding\" alt=\"WGAL logo\"\/><\/p>\n<p>\n\t\t\tUpdated: 10:33 AM EDT Jun 21, 2026\n\t\t<\/p>\n<p>\t\t<a href=\"https:\/\/www.wgal.com\/article\/hearst-television-news-policy-statements\/14471973\" class=\"editorial-standards border-left\" rel=\"nofollow noopener\" target=\"_blank\">Editorial Standards \u24d8<\/a><\/p>\n<p>\n\t\t\t\t\t\tRain chances rise overnight for South-Central PennsylvaniaRain chances will increase overnight tonight and continue into the pre-dawn hours Monday as the next weather system moves in across South-Central Pennsylvania.
