Dispatch: Traffic disrupted after 2 tractor-trailers collide along I-79
YOU CAN REGISTER ONLINE IF YOU WOULD LIKE TO ATTEND. TURNING NOW TO PITTSBURGH’S ACTION WEATHER. WE’RE JOINED NOW BY WEATHER METEOROLOGIST JILL SZWED. OF COURSE, WE ARE WATCHING SEVERE WEATHER ALERT DAY, RIGHT? IT’S A BUSY AFTERNOON ACROSS WESTERN PENNSYLVANIA. REALLY? AGAIN, YET ANOTHER ROUND OF SEVERE WEATHER. WE’VE SEEN A COUPLE ALREADY THIS SEASON, BUT KEEP AN EYE OUT FOR SOME DAMAGING WINDS, ESPECIALLY AFTER 4 OR 5:00 AROUND THE CITY OF PITTSBURGH. IN THE MEANTIME, WE’VE GOT A LOT OF WARMTH COMING OUR WAY. TEMPERATURES MID TO UPPER 70S ALREADY A LITTLE BIT OF A BREEZE AS MORE CLOUDS WILL BE PUSHED IN AHEAD OF THOSE STORM CHANCES. ALL SEVERE THREATS ARE ON THE TABLE, BUT DAMAGING WINDS WILL LEAD THE WAY. EVENTUALLY, WE SWITCH OVER TO MORE OF A HEAVY RAIN THREAT. THAT WILL BE AFTER DARK AS SOME LOCALIZED FLOODING CONCERNS COULD POP UP, ESPECIALLY SOUTH AND EAST OF THE CITY. CERTAINLY DOESN’T LOOK LIKE IT’S GOING TO BE A STORMY AFTERNOON. WE’VE GOT SOME BRILLIANT SUNSHINE HERE ON YOUR SUNDAY. TEMPERATURES ARE GOING TO WARM FAST, BUT OF COURSE WE KNOW THAT CAN COOK UP SOME OF THOSE STORMS INTO THE AFTERNOON. HOW ABOUT CLOSE TO 80 DEGREES TODAY? WASHINGTON 82 IN UNIONTOWN, UPPER 70S ACROSS A GOOD PORTION OF WESTMORELAND, ALLEGHENY, BEAVER, EVEN SOUTHERN BUTLER COUNTIES, TOO. TEMPERATURES WILL BE A TOUCH COOLER AS WE TRAVEL CLOSER TO I-80 AS YOU GET THE STORMS FIRST. SO IN THE MEANTIME, WE ARE BREEZY, VERY WARM. 77 IN PITTSBURGH. SCATTERED SEVERE THUNDERSTORMS AFTER 5:00 FOR THE GREATER PORTION OF WESTERN PENNSYLVANIA THAT WOULD EXTEND THROUGH EVEN PARTS OF THE OVERNIGHT HOURS. EVERYBODY IS DRY BY THE TIME YOU’RE WAKING UP TOMORROW MORNING, BUT IT WILL BE MUCH COOLER IN YOUR 4-DAY PLUS 4 MORE FORECAST 40S, BACK TO THE 50S TUESDAY AND WEDNESDAY. THURSDAY IS ANOTHER DAY TO WATCH. MAY BECOME AN IMPACT DAY FOR US, AS WE’LL SEE MORE RAIN, POTENTIALLY EVEN A FEW MORE ISOLATED THUNDERSTORMS. SEVERE RISK TODAY IS BASICALLY AREA WIDE FOR SCATTERED SEVERE THUNDERSTORMS. AGAIN, THIS IS AFTER FIVE EVEN 6 P.M. FOR A GOOD PORTION OF THE AREA. DAMAGING WINDS STILL A PRIMARY CONCERN. THAT’S UPWARDS OF 60MPH. LARGE HAIL THREAT HAS PICKED UP AT LEAST OVER THE PAST 24 HOURS. THERE COULD BE SOME ISOLATED STORMS THAT PRODUCE UP TO GOLF BALL SIZED HAIL. AND ALSO THOSE DOWNPOURS. CONCERNS FOR FLOODING THAT EXTENDS THROUGH THE OVERNIGHT HOURS WHEN FLOODING IS ESPECIALLY DANGEROUS. THE TORNADO RISK IS LOW, BUT NOT ZERO FOR A BRIEF SPIN UP. LET’S TALK ABOUT THE TIMING. YOU STILL HAVE PLENTY OF TIME TO GET OUTSIDE. ENJOY THIS BEAUTIFUL LATE MARCH DAY THAT’S GOING TO FEEL A BIT MORE LIKE SUMMER IN SOME CASES. HERE’S 3:00. WE COULD SEE SOME VERY ISOLATED SHOWERS NORTH OF I 80, A STORM OR TWO FIRING UP BETWEEN 4 AND 5 P.M. ALONG THE I 80 CORRIDOR AS WE WORK TOWARDS 6:00, THAT’S WHEN THE FOCUS WILL SHIFT CLOSER TO THE CITY OF PITTSBURGH. THOSE STORMS WILL CONTINUE TO HOVER RIGHT AROUND I-70 JUST AS THE SUN IS SETTING AGAIN. DAMAGING WINDS, LARGE HAIL, HEAVY RAIN, THREAT WILL PERSIST. ONCE WE LOSE THAT DAYLIGHT, A LOT OF THE STORMS LOSE AT LEAST THEIR SEVERE QUALITIES. BUT STILL SOME RUMBLES OF THUNDER. VERY HEAVY RAIN WILL EXTEND THROUGH MIDNIGHT, IF NOT BEYOND. AND AGAIN, THESE BACK TO BACK ROUNDS OF DOWNPOURS, WHAT WE CALL TRAINING THUNDERSTORMS, ESPECIALLY FROM I-70 THROUGH THE LAUREL HIGHLANDS, COULD PROMPT THOSE FLOODING CONCERNS THAT WOULD EVEN EXTEND THROUGH THE WEE HOURS OF THE MORNING. FORTUNATELY, THAT RAIN IS CLEAR WELL BEFORE MANY ARE UP AND OUT THE DOOR. MONDAY. OF COURSE, TOMORROW MORNING WE MAY JUST BE NAVIGATING SOME STORM DAMAGE AND MAYBE EVEN SOME WATER ISSUES TOO. BECAUSE OF THAT HEAVY RAIN, ONLY 47, SO CERTAINLY NOT A SPRINGFIELD OF THE DAY. TOMORROW. SUNSHINE 50 FOR US TUESDAY AND WEDNESDAY. LET’S FAST FORWARD TO THURSDAY. THAT WILL BE THE NEXT DAY TO WATCH WITH A COLD FRONT THAT WILL BE APPROACHING RAIN, MAYBE A FEW EMBEDDED THUNDERSTORMS AND YET ANOTHER DROP IN TEMPERATURE WON’T BE QUITE AS DRAMATIC GOING FROM THE 40S CLOSE TO 50 BY THE TIME WE ENTER FRIDAY, AND ALSO THE START OF NEXT WEEKEND. SO KEEP SOME OF THOSE STORMS FIRING UP AGAIN TOWARDS THE END OF THIS WEEK.
