Hottest temps of the year arrive Monday & Tuesday across south-central Pennsylvania
The first 90-degree days of 2026 is expected for the beginning of the week, then Wednesday packs a chance for storms!
LOOKING FOR THEIR FIRST PAY RAISE SINCE 2022. NOW, THE WGAL NEWS EIGHT STORM TEAM FORECAST, WITH METEOROLOGIST RYAN ARGENTINA. WE ARE TRACKING SOME HOT TEMPERATURES AS WE GET INTO OUR MONDAY AND TUESDAY. THAT’S REALLY WHAT’S GOING TO BE THE THEME FOR THE EARLY PORTIONS OF THE WORKWEEK. WE HAD THE FIRST 90 DEGREE DAYS OF THE YEAR. WE COULD POTENTIALLY GO RIGHT NEAR THOSE POSSIBLE RECORDS FOR MONDAY AND TUESDAY. THEN FOR WEDNESDAY, IT’S GOING TO BE OUR NEXT BEST SHOWERS CHANCE. BUT THAT COULD ALSO BE ASSOCIATED WITH SOME SCATTERED THUNDERSTORMS, WHICH IS SOMETHING THAT WE’RE GOING TO BE WATCHING FOR WEDNESDAY. SO WE ALSO MADE WEDNESDAY AN IMPACT DAY. THEN FOR THE REST OF THE WEEK, COOLING BACK DOWN TO THE 60S, ALSO TOWARDS THE 70S FOR THE END OF THE WEEK. SO A BIT OF A COOLER STRETCH IS ON THE WAY AS WE HEAD INTO AS WE HEAD INTO THE END OF THE WEEK. SO A FEW CLOUDS FOR TONIGHT. WARM IT WILL BE. WE COULD SEE SOME PATCHY FOG OVERNIGHT TONIGHT. TEMPERATURES GETTING DOWN INTO THE LOWER 60S, 76 FOR TOMORROW. BUT IT’S GOING TO BE A WIDE TEMPERATURE RANGE. GOING TO SEE TEMPERATURES FROM 72 TO 82 DEGREES ACROSS THE AREA WILL BE QUICKLY WARMING UP WITH MOSTLY SUNNY SKIES. THEN WE’LL SEE MORE SUNSHINE WITH A FEW CLOUDS WORKING THEIR WAY IN. AND WE’LL SEE THE POTENTIAL FOR SOME ISOLATED THUNDER SHOWERS COME INTO PLAY. BUT THAT IMPACT ICON IS FOR THAT HEAT. THOSE TEMPERATURES GETTING INTO THE LOWER 90S. SO WE HAVE 92 FOR MONDAY. THEN WE HAVE 94 FOR TUESDAY, 88 FOR WEDNESDAY. THEN BACK DOWN. YOU CAN SEE DOWN TO THE 60S, ALSO THE 70S AS WE HEAD INTO THE END OF THE WORKWEEK. BUT I WANT TO SHOW YOU ALSO THESE, THE AIR TEMPERATURES AND THE HEAT INDEX. SO THE HEAT INDEX IS WHAT IT’S WHAT IT FEELS LIKE OUTSIDE. SO YOU CAN SEE THE ORANGES. THESE ARE FOR THE AIR TEMPERATURES. THE HEAT INDEX COULD BE A COUPLE DEGREES, MAYBE EVEN A FEW DEGREES ABOVE WHAT THE AIR TEMPERATURE ACTUALLY IS. SO IT COULD BE FEELING LIKE 95 DEGREES. IN THIS CASE, IT’S 94, BUT IT COULD FEEL LIKE 95, 96 DEGREES. AS WE HEAD INTO OUR MONDAY AFTERNOON. ALSO, LET ME SHOW YOU SOME OF THESE RECORDS. THE MONDAY’S HIGH IS GOING TO BE 92, BUT THE RECORD IS 90. BACK IN 1962 IS 94 DEGREES. TUESDAY’S HIGH WAS 94. THE RECORD IS 95, SET BACK IN 1962. SO WE’RE WITHIN ONE DEGREE OF THAT RECORD. SO THAT’S SOMETHING THAT WE’RE GOING TO CONTINUE TO KEEP AN EYE ON AS WE GET INTO OUR MONDAY AND TUESDAY. SO OUTSIDE OF MONDAY AND TUESDAY, WE HAVE THAT SCATTERED THUNDERSTORM CHANCE FOR WEDNESDAY. THAT’S ALSO GOING TO BE AN IMPACT PERIOD FOR THOSE STORM CHANCES. BUT JUST BE AWARE OF THESE HEAT INDICES ARE GOING TO BE GETTING INTO THE MID TO UPPER 90S FOR BOTH MONDAY AND OUR TUESDAY, BUT ALSO POLLEN, THE WEATHER FOR TOMORROW. POLLEN LEVELS WILL BE HIGH FOR THE TREES AND GRASS, LOW MOLD LEVELS, MODERATE AIR QUALITY AND HIGH UV INDEX. GOT ABOUT A 20 MINUTE BURN TIME FOR THE DAY TOMORROW. BUT LOOK AT THIS. SOME WARM SPOTS ACROSS THE AREA. 73 IN HARRISBURG, 78 THOUGH STILL IN CARLISLE, 78 IN CHAMBERSBURG DOWN TO THE LOWER 70S FOR YORK, 75 IN LANCASTER. AT THIS TIME, WE’RE SEEING SOME MAINLY CLEAR CONDITIONS AT THIS TIME, BUT WE’LL CONTINUE TO SEE SOME MAINLY SUNNY CONDITIONS HEADING INTO TOMORROW MORNING. BUT HERE COMES THAT NEXT CHANCE OF AN ISOLATED SHOWER. YOU MAY HAVE A COUPLE RUMBLES OF THUNDER, ESPECIALLY WITH SOME OF THOSE ISOLATED SHOWERS. THEN THEY’LL START TO DWINDLE AS WE GET INTO LATE MONDAY INTO EARLY TUESDAY, YOU CAN SEE LOOKING AT PARTLY TO MAINLY CLEAR CONDITIONS. AND THAT CHANCE FOR THOSE SHOWERS COMES BACK AROUND THE CORNER. ONCE WE GET TO ABOUT 4 TO 8:00 IN THE EVENING FOR FOR OUR TUESDAY. SO IMPACT DAYS, SUMMER, LIKE 92 DEGREES FOR MONDAY 94, HOT AND STICKY FOR YOUR TUESDAY AND A CHANCE OF SOME STORMS ON WEDNESDAY. WILL BE CONTINUING TO WATCH THOSE TEMPERATURES TOO, FOR WEDNESDAY COULD BE GETTING INTO THE UPPER 80S MAYBE COULD MAKE A RUN FOR THE LOWER 90S TO ONCE AGAIN FOR WEDNESDAY. THEN WE’LL BE BACK ON THE COOLER CONDITIONS. SO IF YOU’RE HOPING FOR THAT BREAK, ONCE WE GET PAST THOSE 90S, IT IS COMING. BUT WE ARE LOOKING AT A CHANCE OF SOME SHOWERS AS WE HEAD INTO OUR SATURDAY AND SUNDAY OR MEMORIAL DAY WEEKEND. NOW, JUST AS A SIDE NOTE, I’M GOING TO I INCLUDED THIS RIGHT AFTER THE TEN DAY. SO WITH A LOT OF FOLKS THAT ARE SPENDING TIME OUTDOORS, ESPECIALLY AS WE GET INTO OUR TUESDAY, THAT’S GOING TO BE PRIMARY DAY. YOU’RE GOING TO WANT TO MAKE SURE YOU TAKE INTO ACCOUNT THESE HOT WEATHER SAFETY TIPS. MAKE SURE YOU EAT LIGHT, DRINK PLENTY OF WATER WHEN YOU’RE SPENDING TIME OUTDOORS, MINIMIZE ANY DIRECT EXPOSURE TO THE SUN, AND MAKE SURE YOU’RE STAYING IN AN AIR CONDITIONED ROOM. OR IF YOU’RE OUTSIDE, MAKE SURE YOU HAVE A PORTABLE ELECTRIC FAN ON YOU. SOMETHING. SOMETHING TO BE ABLE TO KEEP YOU COOL AS WE AS YOU SPEND SOME TIME OUTDOORS. BUT I WOULD TRY TO STAY INSIDE IF YOU CAN. IT IS GOING TO BE HOT OUT THERE. JUST MAKE SURE, LIKE I MENTIONED, DRINK PLENTY OF WATER. YEAH. YOU KNOW, THAT’S ALL I SAY. IT’S GOING TO GET ELECTROLYTES HOT. YEAH, THAT’

Partly cloudy skies will remain for tonight with very warm low temps in the lower 60s. Conditions will remain warm & sticky. Patchy fog is possible in some isolated spots. The hottest temperatures of the year arrive Monday and Tuesday, as we get a taste of summerlike warmth. Highs will peak in the low to mid 90s both days. We’ll come very close to the record high Monday of 94° set in 1962, and Tuesday’s record high of 95, also set in 1962. You’ll notice the humidity too. With the heat and humidity, isolated showers and storms are possible each afternoon.Higher rain chances come with a cold front on Wednesday afternoon and evening, as scattered showers and storms roll through the area. Temperatures will remain above average, near 86 degrees. Drier air briefly returns on Thursday, and it won’t be near as warm with highs around 70°.The next system is quickly bringing rain chances back on Friday. It will be much cooler in the mid 60s.Unfortunately, it looks like wet weather continues into the Memorial Day holiday weekend. It is still cool, in the 60s, on Saturday with scattered rain showers. The chance for rain continues Sunday and Monday, although the second half of the holiday is trending drier. Highs slowly rise through the lower 70s.Have a great rest of your night!~ Ryan
