Heavy rain, strong winds to impact south-central Pennsylvania Thursday night into Friday
IT’S AN IMPACT MORNING BECAUSE WE’RE WAITING FOR SOME FOG TO DEVELOP. IT SHOULD BE SETTING IN DURING THE MORNING RUSH, AND THAT MEANS THAT VISIBILITY COULD DROP AS LOW AS A QUARTER MILE IN SOME SPOTS. I AM SEEING SOME REDUCED VISIBILITY IN LANCASTER COUNTY RIGHT NOW. LOOKS LIKE THE CLOUD DECK IS STARTING TO LOWER JUST A LITTLE BIT. WE SEE SOME HAZE IN THE DISTANCE, SO WE’LL KEEP A WATCHFUL EYE ON THAT BECAUSE TEMPERATURES RIGHT NOW THEY’RE IN THE 20S, EVEN TEENS IN SOME AREAS. SO FOG COULD FREEZE ON CONTACT WITH SURFACES PROVIDED IT’S VERY DENSE. BUT I HAVE NOT SEEN THAT YET, SO WE’LL KEEP A WATCHFUL EYE ON IT UNTIL 11 A.M. TODAY. TEMPERATURES GENERALLY 20S, EVEN SOME UPPER TEENS, SO THERE MAY BE SOME SLICK SPOTS ON THE ROADS LATER TODAY. NEWS EIGHT STORM TEAM FORECAST CALLS FOR THOSE AREAS OF FOG, THEN INCREASING CLOUDS. WE GET THE EVENING RAIN WE’VE BEEN ADVERTISING ALL WEEK. IT’S GOING TO BE COMING IN TONIGHT AND COULD BE HEAVY AT TIMES OVERNIGHT. SO IT’S AN IMPACT NIGHT WITH THE RAIN COMING DOWN AND POTENTIAL STRONG GUSTS. I THINK WE COULD SEE SOME GUSTS UP TO 50MPH TONIGHT. AND A WIND ADVISORY IS IN EFFECT BECAUSE OF THAT. NOW TEMPERATURES OVERNIGHT MAY SPIKE UP TO 50 DEGREES IN SOME SPOTS, ESPECIALLY SOUTHERN COUNTIES. AND THEN WE FALL AS WE SEE THE COLD FRONT PASSING EARLY TOMORROW MORNING. TOMORROW AFTERNOON, TEMPERATURES ARE GOING TO BE FALLING INTO THE 30S, BUT THESE ARE YOUR EARLY DAY HIGHS ABOUT 44 TO 48. SO WE WILL SEE TEMPERATURES FALLING. A RAIN OR SNOW SHOWER LEFT OVER BEHIND THE COLD FRONT, AND THOSE POTENTIAL WIND GUSTS TO 45MPH THROUGHOUT THE DAY TOMORROW. BUT THE STRONGEST GUSTS AGAIN COME TONIGHT. ALMANAC 41 DEGREES WAS A HIGH YESTERDAY. AVERAGES 43. SOME SPOTS YESTERDAY MADE IT INTO THE 50S, ESPECIALLY IF YOU GOT THAT AFTERNOON SUN WEST OF THE SUSQUEHANNA RIVER. RIGHT NOW MOST SPOTS ARE IN THE 20S. WE HAVE A FEW TEENS, INCLUDING LANCASTER AND YORK, AND WE’RE WATCHING FOR ANY POTENTIAL FOG DEVELOPMENT. BUT RIGHT NOW IT IS MAINLY CLEAR. SO HIGH PRESSURE IS OFFSHORE. WE HAVE A DISTURBANCE COMING UP FROM THE SOUTH THAT WILL PRODUCE OUR EVENING RAIN. AND HERE’S THE COLD FRONT THAT SWEEPS IN FROM THE WEST TOMORROW MORNING. SO LET ME GIVE YOU THE HOUR BY HOUR FORECAST TODAY. FAIRLY UNEVENTFUL DURING THE DAY. IT PROVIDED. THIS FOG DOESN’T BECOME TOO DENSE THIS MORNING AS WE HEAD TOWARD EVENING. HERE COMES THE RAIN MOVING IN FROM THE SOUTH AND LIGHT INITIALLY, BUT IT WILL BECOME HEAVIER OVERNIGHT. WE’LL GET SOME MODERATE RAIN, SOME POPS OF HEAVY RAIN. AND LOOK AT THAT. THAT’S THE COLD FRONT THAT COMES THROUGH AT ABOUT THIS TIME TOMORROW MORNING. SO THAT COULD BRING SOME STRONG GUSTS ALONG WITH IT. GUSTS OF 40, 50MPH. NOT OUT OF THE QUESTION ACROSS THE AREA OVERNIGHT TOMORROW. DURING THE DAY IT’S STILL QUITE WINDY. THERE WILL BE A LEFTOVER RAIN OR SNOW SHOWER PASSING THROUGH WITH THOSE STRONG WESTERLY WINDS STILL CONTINUING INTO SATURDAY, BUT DIMINISHING PRETTY QUICKLY AFTER SATURDAY MORNING. SO WIND ADVISORY IS IN EFFECT TONIGHT AND ALL DAY TOMORROW. LOOK AT THESE POTENTIAL WIND GUSTS TONIGHT. WE COULD SEE SOME GUSTS IN THE 40 EVEN 50 MILE PER HOUR RANGE AS THAT COLD FRONT PASSES. SO THAT’S WHAT WE’RE GOING TO BE WATCHING OUT FOR WITH THE STRONG GUSTS TONIGHT. LET ME SHOW YOU OUR TEN DAY FORECAST. TODAY’S HIGH 46. WE GET TO NEAR 50 TONIGHT. KIND OF SPIKES OVERNIGHT. AND THEN ABOUT 46 BY SUNRISE TOMORROW. THAT WILL BE OUR HIGH TOMORROW. THEN TEMPERATURES GRADUALLY FALL DURING THE DAY. WE GO WITH 40 ON SATURDAY. SUNDAY’S HIGH IS 46 FOR THE FIRST DAY OF WINTER. A LITTLE BIT COOLER ON MONDAY BEHIND A DRY COLD FRONT AND THEN IT LOOKS A BIT MORE CONSISTENT FOR THE REST OF CHRISTMAS WEEK THERE, WITH HIGHS IN THE 40S AND LOWS IN THE 30S. A COUPLE OF CHANCES, SOME MINOR CHANCES FOR RAIN.
