Heat and humidity return to South-Central Pennsylvania by late week
STRONG WEATHER SYSTEM SOUTH OF NEW ZEALAND. NOW, THE GAL NEWS EIGHT STORM TEAM FORECAST WITH METEOROLOGIST MIKE SUSKO GOOD MONDAY AFTERNOON, EVERYONE. IT’S GOING TO REMAIN PLEASANT THROUGH THE DAY TODAY AS WELL AS TOMORROW. BUT THEN WE HEAT THINGS UP AS WE HEAD INTO WEDNESDAY, AND ESPECIALLY THURSDAY AND ALSO FRIDAY. THERE IS A VERY HOT WITH THOSE HEAT INDEX VALUES IN THE MID TO UPPER 90S ACROSS THE AREA IN THE AFTERNOON. HERE’S WHY DEW POINTS ARE GOING TO GO BACK INTO THE STICKY AND HUMID CATEGORY AND CLOSE TO THE 70S THERE. IN SOME CASES WHERE IT CAN JUST BE DOWNRIGHT STEAMY AND TROPICAL. AND THE MORE WE ADD MOISTURE TO THE AIR, THE WORSE THAT HUMIDITY IS GOING TO BE. SO AS WE GO INTO THURSDAY AND FRIDAY, WE NEED TO WATCH FOR THAT HOT AND HUMID CONDITIONS WITH, IN SOME CASES, THOSE TEMPERATURES APPROACHING RECORD HIGHS. THE FEELS LIKE TEMPERATURES, AS I MENTIONED, WILL BE IN THE MID TO UPPER 90S AND NOT MUCH RELIEF OVERNIGHT EITHER. AS WE HEAD TOWARDS THE LATER PART OF THE WEEK, THE OVERNIGHT LOWS ARE EXPECTED TO BE IN THE LOW 70S AND COULD EVEN BE NEAR RECORD WARM TERRITORY. SO UNFORTUNATELY NOT GETTING MUCH OF A COOL DOWN AT NIGHT. SO JUST MAKE SURE YOU’RE REMAINING HYDRATED, TAKING BREAKS OFTEN, AND ALSO PLEASE REMEMBER TO KEEP THE WATCH KIDS, PETS AND ELDERLY IN THE CAR, BUT WE ARE EXPECTING TO BE IN THAT MAJOR CATEGORY FOR HEAT RISK ACROSS THE SUSQUEHANNA VALLEY HERE. AS WE GO INTO THURSDAY, BUT ALSO AS WE HEAD INTO FRIDAY AS WELL, ESPECIALLY IN MORE OF THOSE URBAN AREAS OF THE SUSQUEHANNA VALLEY HERE. AND WHAT THIS MEANS IS, BASICALLY, IF YOU ARE SENSITIVE TO HEAT, YOU COULD END UP HAVING SOME MORE DIFFICULTY, ESPECIALLY IF YOU’RE IN THAT MODERATE RANGE. THINK YOUNG CHILDREN, ELDERLY, THOSE WITH UNDERLYING HEALTH ISSUES. YOU WANT TO MAKE SURE YOU’RE TAKING THAT SERIOUSLY. AND ESPECIALLY ONCE WE GET INTO THE MAJOR OR THAT RED CATEGORY, THAT’S WHERE IT CAN START GETTING DANGEROUS FOR NOT ONLY THOSE WHO ARE SENSITIVE TO HEAT, BUT REALLY EVERYONE. SO AGAIN, WE JUST GOT TO WATCH LATER THIS WEEK HERE FOR THAT EXTREME HEAT. HARRISBURG RIGHT NOW THOUGH, THE CLOUDS ARE CLEARING OUT. THAT’S ONE POSITIVE HERE ACROSS THE SUSQUEHANNA VALLEY. IT’S 71 DEGREES IN THE CAPITAL AND ACROSS THE AREA, 70 IN LANCASTER, 70 IN YORK, 75 IN GETTYSBURG AND 76 THERE IN CHAMBERSBURG AND 69 IN CARLISLE. THESE CLOUDS ARE STARTING TO BREAK UP HERE ON STORM TRACK LIVE RADAR NETWORK, AND THEY WILL CONTINUE TO DECREASE AS WE HEAD TOWARDS THE AFTERNOON. SO TEMPERATURES WILL GO UP TO AROUND 80 DEGREES. AND AS I SAID, WE WILL GET THOSE CLOUDS TO DECREASE AS WE HEAD TOWARDS THE EVENING HOURS HERE. WITH THOSE OVERNIGHT LOWS DROPPING BACK TO AROUND 58 DEGREES WITH A MOSTLY CLEAR SKY, IT’S COOLER, A LIGHT BREEZE OUT OF THE SOUTHEAST AROUND 5 TO 10MPH. TOMORROW IS WARMER. WE’RE GETTING TO THE MID 80S, BUT STILL RELATIVELY PLEASANT. HUMIDITY IS EXPECTED TO BE ON THE LOWER SIDE HERE, SO IT WILL BE ENJOYABLE DAY ON YOUR TUESDAY. AND AS WE LOOK AT PREDICTOR AGAIN, THOSE CLOUDS CONTINUE TO CLEAR OUT AS WE GO THROUGH YOUR DAY TODAY. TOMORROW WE KEEP THE CLOUDS A LITTLE BIT AT TIMES HERE, BUT STILL A DRY DAY. ANY RAIN SHOULD STAY OFF TO THE WEST. A WARM FRONT WILL MOVE IN AS WE HEAD INTO YOUR WEDNESDAY, OFFERING A CHANCE FOR SOME SHOWERS AND THUNDERSTORMS AT TIMES NOT EXPECTING A WASHOUT, BUT STILL SOMETHING WE NEED TO WATCH HERE AS WE HEAD TOWARDS THE MIDDLE PART OF THE WEEK AND YOUR TEN DAY FORECAST. ONCE WE GET TO THURSDAY AND FRIDAY, THE HEAT IS ON 92 FOR THE HIGH THERE ON THURSDAY AS WELL AS FRIDAY. AND THEN AS WE GO INTO SATURDAY, ANOTHER DAY THERE IN THE 90S AGAIN, COULD BE THE FIRST HEAT WAVE OF THE YEAR. AN
