250 I’M SCOTT MCDONNELL AT ACADIA NATIONAL PARK IN MAINE. TURNING NOW TO PITTSBURGH’S ACTION WEATHER METEOROLOGIST JILL SZWED YOUR CERTIFIED MOST ACCURATE FORECAST. GOOD NEWS, GOOD WEEKEND. BAD NEWS MONDAY. I KNOW RIGHT, BUT WE’RE NOT GOING TO WORRY ABOUT MONDAY. IT’S A GORGEOUS WEEKEND HERE ACROSS WESTERN PENNSYLVANIA. GREAT TO DO A LITTLE EXPLORING OR TAKING A LOT OF BIG EVENTS GOING ON THIS WEEKEND AS WE CONTINUE WITH THIS JUNETEENTH HOLIDAY WEEKEND, AN OUTSIDE CHANCE OF A PASSING SHOWER THIS AFTERNOON, MAYBE A RUMBLE OF THUNDER. BUT FOR THE MOST PART, THE MAJORITY OF WESTERN PA WE’RE KEEPING IT DRY, KEEPING IT GOOD ALL WEEKEND LONG WITH TEMPERATURES CLOSING IN ON 80 FOR FATHER’S DAY TOMORROW. LOVE TO SEE IT. TONS OF BLUE SKY OVER OUR CITY HERE THIS MORNING AS WE GO THROUGH THE AFTERNOON, A FEW CLOUDS WILL POP UP, PROVIDING A LITTLE BIT OF DECORATION, BUT CERTAINLY A NICE START TO THE DAY HERE AS WE GEAR UP FOR THE WEEKEND. TEMPERATURES EQUALLY AS NICE. JUST ABOUT EVERYBODY IN THE 70S THIS AFTERNOON A LITTLE CLOSER TO 80 FOR SPOTS LIKE BEAVER, EVEN HERE IN PITTSBURGH, MONROEVILLE TO 78 FOR UNIONTOWN, MID 70S. WASHINGTON, INDIANA. ALSO BUTLER UP ALONG I-80. YOUR TEMPERATURES WILL BE CLOSING IN ON 70 THIS AFTERNOON. AS I MENTIONED, THERE’S A SMALL CHANCE I HATE TO EVEN MENTION IT, BUT WE DON’T WANT YOU TO GET CAUGHT BY A SHOWER OR RUMBLE OF THUNDER A LITTLE LATER ON. TODAY. COULD SEE SOME ACTION AS EARLY AS ABOUT 11:00 NOON. THAT’LL BE CLOSER TO 422, AND I-80 MAY SEE SOME ACTIVITY DROPPING CLOSER TO BEAVER. EVEN HERE IN ALLEGHENY COUNTY AROUND GREENSBURG. AS WE DRAW CLOSER TO DINNER TIME. SO JUST SOMETHING TO BE MINDFUL OF. YOU’LL BE FIRING UP THE GRILL FOR DINNER A LITTLE LATER ON THIS EVENING. OTHERWISE, ACTIVITY WILL FIZZLE AS THE SUN GOES DOWN AND WE’LL KEEP IT DRY TONIGHT AND THROUGHOUT THE DAY. ON FATHER’S DAY TOMORROW. VERY COMFORTABLE. IF YOU HAVE BRUNCH PLANS WITH DAD IN THE MORNING, MAYBE A MORNING TEE TIME. WE START OFF AROUND 6073 BY NOON, 80 WITH INCREASING CLOUDS AS WE GEAR UP FOR THAT DREADED DAY ON MONDAY. BACK TO WORK AFTER A LONG WEEKEND. ALSO BACK TO RAIN CHANCES AND AN IMPACT DAY. LET ME CHECK IT ALL OUT FOR YOU. SO AS WE GO THROUGH THE EVENING HOURS TOMORROW, GET INCREASING CLOUDS FOR YOUR SUNDAY. THIS LATEST ROUND OF FUTURECAST DELAYS THE RAIN JUST A LITTLE BIT. BUT WHAT WE CAN SAY IS IT’S GOING TO BE AFTER DARK AFTER MIDNIGHT THAT WE SEE THAT INITIAL ONSET HERE, 7:00 IN THE MORNING. EVEN SOME LIGHT RAIN COULD CAUSE SOME PROBLEMS ON THE ROADS. IT GETS STEADIER AND HEAVIER AS THE MORNING EVOLVES. THE EXACT TIMING OF THAT WINDOW, THE HEAVIEST RAIN. WE’RE GOING TO CONTINUE TO NAIL THAT DOWN HERE THIS WEEKEND SO YOU CAN PLAN AHEAD. BUT A DECENT SOAKING TO START OFF YOUR MONDAY INTO THE AFTERNOON. THIS SYSTEM IS GOING TO HANG OUT JUST TO OUR SOUTH, AND THAT WILL LEAD TO ONGOING RAIN CONCERNS, POSSIBLY EVEN A FEW THUNDERSTORMS THAT COULD LEAD TO SOME FLOODING ISSUES, A SOAKING INCH OR MORE OF RAIN IS GOING TO FALL ON MONDAY ALONE, SO WE WILL BE MONITORING SOME ISSUES FOR FLOODING, ESPECIALLY IN URBAN AREAS. POOR DRAINAGE, FLOOD PRONE SPOTS AS WE GO THROUGH MONDAY. ONCE WE KNOCK THAT SYSTEM OUT, WE’RE GOLDEN NEXT WEEK TALKING ABOUT A GOOD AMOUNT OF SUNSHINE. TEMPERATURES ARE GOING TO BE GREAT TOO. FOR THE FIRST WEEK OF SUMMER, LOWS IN THE 50S. HIGHS EDGING CLOSER TO 80 DEGREES FOR THE MIDDLE OF NEXT WEEK. WITH THOSE COMFORTABLE MORNINGS. THAT ALSO MEANS HUMIDITY LEVELS WON’T BE TOO BAD. LOOKS TO BE PRETTY DRY TOO. SO A LOT OF SUMMER CAMPS, THE POOLS AS WELL. VERY BUSY NEXT WEEK
