IMPACT DAY: Damaging winds, heavy rain could bring down trees, wires in south-central Pennsylvania

THE ENTIRE AREA IS UNDER A WIND ADVISORY. THAT WILL CONTINUE UNTIL 1 A.M. SUSTAINED WINDS EXPECTED OUT OF THE WEST NORTHWEST 15 TO 25MPH. GUSTS 40 TO 45 WITH ISOLATED GUSTS CLOSE TO 50MPH POSSIBLE. THAT COULD RESULT IN SOME DOWNED TREE BRANCHES, WHICH MAY LEAD TO SOME ISOLATED POWER OUTAGES. AND, OF COURSE, CHRISTMAS DECORATIONS THAT ARE OUTSIDE. MAKE SURE THEY’RE SECURE YOUR TRASH CANS AND YOUR RECYCLE BINS ARE ALREADY SEEING IMPRESSIVE WIND GUSTS AT THIS HOUR. 44 MILE PER HOUR WIND GUSTS IN CHAMBERSBURG. 43 IN HARRISBURG, 26 IN LANCASTER AND 30 IN SELINSGROVE. AND THEY WILL CONTINUE STRONG AS A FRONT IS COMING THROUGH THIS MORNING. THEN THEY DROP BACK JUST A LITTLE BIT, BUT THEN THEY RAMP BACK UP AND WE COULD SEE GUSTS CLOSE TO 40 45 MILE PER HOUR, MILES PER HOUR. LATER THIS AFTERNOON INTO THE EARLY EVENING. SO JUST KEEP THAT IN MIND. IT COULD BE A SLOW COMMUTE THIS MORNING. WE DO HAVE A BREAK IN THE SHOWER ACTIVITY, BUT NOTICE THIS LINE, THIS LITTLE SLIVER HERE THAT’S GOING TO PRODUCE SOME BRIEF HEAVY DOWNPOURS. ALSO, THE POSSIBILITY OF SOME STRONG DAMAGING WIND GUSTS, ESPECIALLY AS IT MOVES EAST INTO OUR EASTERN COUNTIES, AND ALSO SOME BRIEF HEAVY DOWNPOURS. SO THIS IS GOING TO CONTINUE TO MOVE INTO OUR WESTERN COUNTIES AND CONTINUE TO TRACK ACROSS THE SUSQUEHANNA VALLEY. IT WILL BE IN OUR EASTERN COUNTIES BETWEEN 8 AND 9 A.M. THIS MORNING. AND YOU CAN SEE THIS LINE EXTENDS ALL THE WAY DOWN INTO MARYLAND. SO WE’RE NOT DONE WITH THE RAIN JUST YET. THIS FRONT WILL MAKE ITS WAY THROUGH NOW. WE’RE MILD RIGHT NOW, BUT ONCE THAT FRONT COMES IN, THAT’S GOING TO DROP TEMPERATURES. SO YOUR NEWS EIGHT STORM TEAM FORECAST. WE’VE GOT 50S MID 50S AT THIS HOUR. THE RAIN WILL BE TAPERING LATER THIS MORNING. TEMPERATURES WILL FALL INTO THE MID 40S EARLY AFTERNOON AND THEN INTO THE 30S BY LATE AFTERNOON. NOW AROUND 1:00 2:00 A WEAK BOUNDARY COMES THROUGH. COULD SPIT OUT A FEW RAIN AND OR SNOW SHOWERS, AND THEN WE’RE DONE WITH THE PRECIPITATION. SKIES WILL BE CLEARING. TEMPERATURES WILL CONTINUE TO FALL THIS EVENING INTO THE 20S, BUT WITH THOSE GUSTY WINDS, IT’S GOING TO FEEL LIKE THE TEENS OVERNIGHT TONIGHT. PARTLY TO MOSTLY CLEAR. WINDS WILL CONTINUE TO EASE UP. TEMPERATURES DROP INTO THE LOW 20S, BUT AGAIN IT’S GOING TO BE FEELING LIKE THE TEENS TOMORROW. MUCH LIGHTER WINDS EXPECTED. WE’LL SEE. PARTLY SUNNY SKIES AND TEMPERATURES WILL BE RIGHT WHERE THEY SHOULD BE FOR THIS TIME OF YEAR. NEAR 40 DEGREES. LOOK AT THESE NUMBERS RIGHT NOW THOUGH. MID TO UPPER 50S. IT WILL FEEL MILD AS YOU STEP OUT THIS MORNING. BUT THAT WON’T BE THE CASE AS YOU’RE MAKING YOUR WAY HOME. AS I JUST MENTIONED, TEMPERATURES ARE GOING TO BE FALLING AND YOU CAN SEE THEY’RE ALREADY FALLING IN OUR WESTERN COUNTIES, WESTERN AREAS OF THE STATE. PITTSBURGH AT 45, ERIE AT 33. AND WE’LL SEE TEMPERATURES FALLING INTO THE 30S LATER THIS AFTERNOON. SO OUR FRONT WILL MAKE ITS WAY THE FIRST ONE INTO OUR EASTERN COUNTIES BY 9:00 10:00 THAT RAIN IS MOVING OUT. THEN WE GET THE SECONDARY FRONT THAT COMES THROUGH THAT COULD SPIT OUT A SHOWER OR TWO, AND THEN MAYBE EVEN A FEW SNOW SHOWERS TO FOLLOW AS THAT SECOND FRONT COMES IN. IT’S GOING TO STAY WINDY FOR THE EVENING, BUT HIGH PRESSURE BUILDING IN TOMORROW WILL HELP TO RELAX THE WINDS FOR THE START OF THE WEEKEND. WE HAVE SUNSHINE AND THEN THE CLOUDS WILL BUILD IN TOMORROW AFTERNOON, BUT IT STAYS DRY. SUNDAY. WE’LL SEE PARTLY SUNNY SKIES AND DRY CONDITIONS. HIGH PRESSURE BUILDS IN. BRINGS US A NICE SECOND HALF TO THE WEEKEND. RAINFALL POTENTIAL. STILL LOOKING AT CLOSE TO 4/10 OF AN INCH TO THREE QUARTERS OF AN INCH. SOME ISOLATED AMOUNTS A LITTLE BIT HIGHER THAN THAT TEN DAY FORECAST SHOWS THAT TEMPERATURES WILL CONTINUE AROUND 40 ON SATURDAY, 44 SUNDAY. THEN THEY DROP BACK INTO THE MID 30S ON MONDAY, BUT IT LOOKS DRY TO KICK OFF. THE HOLIDAY WEEK LOOKS LIKE A COUPLE OPPORTUNITI
