Severe Thunderstorm Watch issued for south-central Pennsylvania
THE FAA AND THE NTSB ARE INVESTIGATING. IT’S AN IMPACT EVENING FOR THE THREAT OF STRONG, SEVERE STORMS. AND WE’RE ALREADY STARTING TO SEE THOSE STORMS CLOSE IN ACROSS THE AREA. WE ACTUALLY HAVE OUR FIRST SEVERE THUNDERSTORM WARNING OF THE EVENING. I WANT TO ZOOM IN HERE SO YOU CAN SEE WHERE THE CELL IS AT. SPECIFICALLY. THIS HAS SPECIFICALLY A CONSIDERABLE TAG, WHICH MEANS IT HAS 70 MILE PER HOUR WINDS. AND ALSO THE OTHER PART OF THE DETAILS HERE, IT HAS ABOUT 1.25IN SIZED HAIL THAT’S GOING TO BE FALLING OUT OF THESE THESE STORMS. AND THAT’S JUST STARTING TO ENTER IN INTO SOUTHERN FRANKLIN COUNTY. SO MERCERSBURG, GREENCASTLE, CHAMBERSBURG, ALSO TOWARDS SOUTH MOUNTAIN AND WAYNESBORO. YOU ARE ALL ALONG HERE ALSO CHAMBERSBURG, YOU’RE ALL IN THIS IN THIS SEVERE THUNDERSTORM WARNING AS IT MOVES ITS WAY NORTH AND EAST. SO KEEP THAT IN MIND AS WE GO THROUGH THE EVENING. WE’RE GOING TO BE SEEING MORE OF THE SEVERE WEATHER, ESPECIALLY LATER, ONCE WE GET CLOSER TO ABOUT 8 OR 9:00, 10:00. BUT LOOK AT THIS NASTY LINE OF SOME SHOWERS AND STORMS, MAINLY STORMS. YOU CAN SEE THESE SEVERE THUNDERSTORM WARNINGS ALSO HAVE WHAT ARE KNOWN AS TORNADO POSSIBLE TAGS. AND YOU CAN SEE SOME OF THE RED BOXES THAT WE ARE SEEING HERE. SOME TORNADO WARNINGS ARE ALREADY ISSUED NOT FOR OUR AREA BUT TOWARDS NORTHERN PENNSYLVANIA AT THIS TIME. AND THIS IS WHAT’S GOING TO BE COMING THROUGH. AS WE HEAD INTO THE EVENING, YOU SEE THE CLUSTER OF SHOWERS AND STORMS TOWARDS THE BLUE MOUNTAIN RIDGE STARTING TO CLOSE IN ON OUR WESTERN COMMUNITIES. SO THIS IS WHAT WE’RE TRACKING AS WE GET INTO THE REST OF, OF TODAY. AND SO RIGHT NOW, YOU CAN SEE IT’S A LEVEL TWO OUT OF FIVE SEVERE WEATHER RISK. AND THIS HAS BEEN ISSUED BY THE STORM PREDICTION CENTER. THAT’S GOING TO BE FROM NOW UNTIL 1 A.M. IS WHEN WE HAVE THAT PERIOD OR THE TIMING OF THESE STORMS UNTIL. SO WHAT TO EXPECT A FEW POP UP STORMS LIKE WE’RE SEEING ALREADY. AND THEN WE’RE GOING TO BE SEEING A LINE OF STORMS LATE AS WE GET INTO CLOSER TO ABOUT EIGHT, 9:00. THAT’S WHEN WE’LL START TO SEE THAT LINE THAT I SHOWED YOU ON THE RADAR. THAT’S WHEN WE’LL START TO SEE THAT START TO PUSH THROUGH. THE MAIN THREATS, HOWEVER, ARE GOING TO BE DAMAGING WINDS, HAIL, HEAVY RAIN. IT’S A LOW CHANCE OR A LOW THREAT FOR FLASH FLOODING AND A LOW THREAT OR CHANCE FOR A SPIN UP TORNADO. BUT WE’RE ALREADY STARTING TO SEE SOME ROTATION IN SOME OF THESE STORMS THAT ARE OUT WEST. SO IT’S SOMETHING THAT WILL CONTINUE TO MONITOR AS WE GET INTO THE NEXT SEVERAL HOURS HERE. SO IN TERMS OF THE LEVELS OR THE THREAT LEVEL, YOU CAN SEE IT’S THE HIGHEST THREAT IS GOING TO BE THESE DAMAGING WINDS. AND YOU CAN SEE LOWER THREAT FOR TORNADOES, A LOWER THREAT FOR LARGE HAIL AND A LOWER THREAT FOR FLASH FLOODING HEADING INTO AGAIN, THAT’S UP TO 1 A.M. MONDAY. SO LET ME SHOW YOU WHAT THE PREDICTOR HERE. WHY I’M SAYING EIGHT TO ABOUT 9:00 IS WHAT I’M GOING TO BE EXPECTING THIS LINE OF STORMS TO COME THROUGH. YOU CAN SEE RIGHT AROUND 8:00, 9:00 STARTING TO ENTER INTO OUR WESTERN COMMUNITIES, STILL SEEING THOUGH A FEW SHOWERS AND STORMS JUST TO OUR EASTERN COMMUNITIES. AS THAT CONTINUES TO PUSH EAST. YOU CAN SEE LOOK AT THAT LINE OF STORMS RIGHT IN THE HEART OF THE SUSQUEHANNA VALLEY, ALREADY STARTING TO APPROACH HARRISBURG, ALSO TOWARDS YORK, ALREADY PASSING THROUGH CUMBERLAND AND ADAMS COUNTY BY THAT POINT. ONCE WE GO FURTHER IN TIME, YOU CAN SEE RIGHT AROUND TEN, 1030 AT NIGHT. THAT’S WHEN WE’RE GOING TO START TO SEE THAT LINE START TO PUSH INTO OR START TO PUSH INTO OUR SOUTH AND EASTERNMOST COMMUNITIES TOWARDS YORK, AND ESPECIALLY TOWARDS LANCASTER COUNTIES. ONCE THAT LINE MOVES OUT, STILL SEEING THE CHANCE OF SOME LINGERING SHOWERS. SO GOING TO EXTEND THAT IMPACT UNTIL ABOUT 12 OR 1:00 IN THE MORNING. ONCE THOSE LINGERING SHOWERS PUSH OUT, YOU CAN SEE WE’LL SEE SOME CLEARING. AND WE’RE LOOKING AT SOME WE’RE LOOKING AT PARTLY TO MOSTLY SUNNY CONDITIONS AS WE HEAD INTO OUR DAY TOMORROW. SO THIS IS HERE’S SOME OF THE DETAILS ONCE AGAIN. SO FROM NOW TILL EIGHT, EXPECT THESE ISOLATED STORMS TO START TO MOVE THROUGH. AND THEN FROM 8 P.M. TO ABOUT 1 A.M. THAT’S THAT’S THE TIME PERIOD OF THAT LINE OF STORMS. THAT’S, THAT’S WHAT’S GOING TO BE COMING THROUGH FROM WEST TO EAST. MAIN THREATS HERE, DAMAGING WINDS, HAIL, BRIEF HEAVY RAIN, FLASH FLOODING, AND A POSSIBLE SPIN UP TORNADO. SO STORMS MOVE THROUGH STRONG SEVERE. FOR THIS EVENING. IT WILL BE STICKY AS NOT IT IS NOT ALERT IS IMPACT BY THE WAY. SO SHOWERS AND STORMS DO END AS WE HEAD INTO TONIGHT WITH DECREASING CLOUDS AND DROPPING HUMIDITY. TEMPERATURES DROPPING DOWN TO THE 60S, 74 TO 78 DEGREES FOR TOMORROW. PARTLY SUNNY, COMFY AND COOLER AND A LITTLE BIT BREEZY, BUT YOU CAN SEE TEMPERATURES INTO THE 80S. YOU CAN SEE ALSO YOU CAN SEE THE DEW POINT TEMPERATURES INTO THE 60S ACROSS THE AREA. SO THAT’S SOMETHING WE’RE GOING TO BE WATCHING. IS THIS RADAR HERE. YOU CAN SEE THAT SEVERE THUNDERSTORM WARNING STILL MOVING IN. AND YOU CAN SEE THOSE SHOWERS AND STORMS BEGINNING TO PUSH INTO THE HEART OF THE SUSQUEHANNA VALLEY. THIS IS WHAT WE’RE GOING TO CONTINUE TO MONITOR AS WE GO THROUGH THE REST OF THIS EVENING. NOW, LOOKING AHEAD INTO NEXT WEEK, WE DO START ON A SUNNIER NOTE. IT’LL BE MORE PLEASANT TO ONCE WE GET INTO MONDAY AND TUESDAY, THE NEXT BEST CHANCE OF STORMS, HOWEVER, LOOKS LIKE IT’S GOING TO BE THURSDAY OF NEXT WEEK AND THE FOLLOWING WEEKEND FOR
