Winter Storm Watch issued for all of south-central Pennsylvania ahead of major weekend snowstorm
WE STILL HAVE SOME SNOW ON THE GROUND IN SPOTS AND IT’S GOING TO BE MELTING WITH TEMPERATURES ABOVE FREEZING. BUT LET ME SHOW YOU, THIS WINTER STORM WATCH THAT HAS BEEN POSTED FOR OUR AREA. THAT GOES FROM 10 P.M. SATURDAY UNTIL 1 P.M. MONDAY. SO WE ARE WATCHING FOR THE POTENTIAL FOR A WINTER STORM WARNING. I THINK WE’LL GET ONE AS WE HEAD INTO TOMORROW FROM THE NATIONAL WEATHER SERVICE. HERE’S THE PREDICTOR SHOWING THE STORM STARTING TO MOVE IN LATE ON SATURDAY. YOU CAN SEE THE BRIGHTER WHITES INDICATING THAT HEAVIER CHANCE OF SNOW EARLY SUNDAY MORNING INTO SUNDAY AFTERNOON. AND THEN WATCH THIS. THIS IS SOMETHING NEW THAT WE’VE BEEN TRACKING. YOU SEE THE PINK DOWN HERE? THIS IS A MIXED LINE, PERHAPS WITH SOME SLEET OR EVEN FREEZING RAIN. WELL, TO OUR SOUTH. SO I DO THINK SOME SLEET MIGHT TRY TO SNEAK UP INTO LANCASTER, YORK, POSSIBLY ADAMS COUNTIES AT THE END OF THE STORM. WE’LL STILL GET PLENTY OF SNOW BEFORE THAT, BUT THERE COULD BE A LITTLE SLEET. NOW, TOWARD THE END OF THE STORM, AS LOW PRESSURE COMES FARTHER NORTH. SO WE WILL KEEP YOU POSTED ON THAT. BUT TEMPERATURES ARE STILL GOING TO BE COLD AS THAT SNOW IS FALLING. SO SUNDAY, OF COURSE, IS AN ALERT DAY. THE SNOW WILL START SATURDAY NIGHT AND EARLY MONDAY. THE BULK OF IT FALLS DURING SUNDAY. IT COULD BE A SIGNIFICANT SNOWFALL, MEANING 12IN OR MORE OF SNOW IS POSSIBLE. AND WE’LL WATCH THAT MIX LINE TO SEE IF IT IMPACTS TOTALS. BUT AGAIN, I THINK THAT’S TOWARD THE END OF THE STORM, AND MOST OF YOUR TOTALS WILL ALREADY BE DOWN. SO HAZARDOUS TRAVEL ON SUNDAY WE COULD SEE SNOWFALL RATES OF ONE INCH PER HOUR AT TIMES, OF COURSE, THE FRIGID TEMPERATURES AND THEN BLOWING AND DRIFTING SNOW BEHIND THE STORM ON MONDAY. AS FAR AS SNOWFALL CONFIDENCE GOES, WE’RE HIGHLY CONFIDENT THAT WE GET SIX INCHES OF SNOW. LIKELY THAT WE COULD GET 12 POSSIBLE FOR 18, BUT NOT AS LIKELY, AND A LOW CHANCE OF 24IN. NOW HERE’S A LOOK AT OUR EXPECTED IMPACTS. ROAD CONDITIONS ARE GOING TO BECOME HAZARDOUS ON SUNDAY. TRAVEL DISRUPTIONS WILL BE VERY HIGH. VISIBILITY COULD BE POOR AT TIMES, ESPECIALLY IF THE SNOW IS FALLING HEAVILY. AND WE’LL KEEP AN EYE ON THOSE WINDS THAT PICK UP BEHIND THE STORM FOR ANY ISOLATED POWER OUTAGES. AS WE HEAD INTO SUNDAY NIGHT AND MONDAY. AS FAR AS OUR FORECAST GOES TODAY, THOUGH, WE HAVE A MORNING SNOW SHOWER OR A LITTLE BIT OF SPRINKLE ACTIVITY OUT THERE. THEN A MIX OF CLOUDS AND SUNSHINE, BREEZY AND MILDER. YOU WON’T SEE THESE NUMBERS FOR A WHILE, SO ENJOY! TODAY 42 TO 46 TONIGHT. MOSTLY CLEAR A BRISK BREEZE. IT’S GOING TO FEEL LIKE THE TEENS WITH TEMPERATURES IN THE 20S. AND THEN FOR TOMORROW WE HAVE 30S, WHICH MIGHT NOT SEEM THAT BAD, BUT THE WIND DOES PICK UP AS AN ARCTIC BOUNDARY COMES IN, SO THE WIND WILL BE GUSTING TO 35MPH OUT OF THE NORTHWEST, AND THAT IS GOING TO DRAG DOWN OUR TEMPERATURES FRIDAY NIGHT INTO SATURDAY MORNING. WE COULD HAVE SUBZERO WIND CHILLS, SO WE WILL KEEP YOU UPDATED ON THAT FACT AS WELL. ON THE ALMANAC. YESTERDAY’S HIGH GOT TO 40 AVERAGES 38 AVERAGE LOW IS 22. SO RIGHT NOW WE ARE AROUND THAT 40 MARK ACTUALLY DIDN’T FALL VERY MUCH FROM THE HIGH YESTERDAY. AND THAT IS MUCH, MUCH WARMER THAN THE NUMBERS THAT WE SAW YESTERDAY ON THIS MAP. WIND SPEEDS ARE STILL UP THERE. SO THAT WILL ADD JUST A LITTLE BIT OF A CHILL TO THE AIR. BUT AS FAR AS OUR WIND SPEEDS GO TODAY, I’D SAY 10 TO 20MPH. AND THEN THE WIND SPEEDS REALLY INCREASE BY TOMORROW. SERIES OF FRONTS HAVE COME THROUGH. THERE’S ONE OFFSHORE, ONE JUST TO OUR WEST, ANOTHER ONE BACK IN THE GREAT LAKES. I DON’T THINK THERE’S MUCH COLD AIR BEHIND THIS FRONT TODAY, BUT IT MAY PRODUCE JUST A STRAY MORNING RAIN OR SNOW SHOWER FOR YOU. SO YOU SEE HERE ON THE PREDICTOR, THINGS ARE FAIRLY QUIET TODAY. ENJOY THE SUN, ENJOY THE MILD AIR. TONIGHT WE’LL SEE PARTLY CLOUDY SKIES. AND THEN FOR TOMORROW, MIX OF CLOUDS AND SUN. THAT ARCTIC BOUNDARY COMES IN AND BOY IT’S GOING TO GET COLD LATE. AND THEN FOR SATURDAY THE CLOUDS WILL GRADUALLY INCREASE. AND OF COURSE WE SHOWED YOU THAT SNOW ON SUNDAY. HERE’S A LOOK AT THE IMPACTS FOR WIND CHILLS AT THE END OF THE WEEK. WE’RE TALKING LATE FRIDAY EVENING INTO SATURDAY AFTERNOON WITH SUBZERO WIND CHILLS AHEAD OF THE WINTER STORM. YOU WANT TO LIMIT YOUR OUTDOOR EXPOSURE IF YOU CAN, OR YOU MUST COVER UP ALL EXPOSED SKIN. SO LOOK AT THAT. THAT’S FRIDAY EVENING. SUBZERO CHILLS OVERNIGHT. WE COULD HAVE CHILLS AS LOW AS TEN BELOW ZERO. AND THEN AS WE HEAD INTO SATURDAY, THOSE CHILLS ARE STILL QUITE SIGNIFICANT. BUT THEY DO IMPROVE. IF YOU CAN SAY THAT TO THE SINGLE DIGITS SATURDAY AFTERNOON. SO LOOK AT SATURDAY’S HIGH. IT’S ONLY 18 SUNDAY 18 WITH THAT SNOW COMING DOWN HEAVY AT TIMES. IT’S GOING TO GET HARD TO CLEAN THAT SNOW UP BECAUSE WE’LL HAVE BLOWING AND DRIFTING SNOW ON MONDAY BEHIND THE STORM, AND THEN NEXT WEEK IS JUST DOWNRIGHT FRIGID AND BLUSTERY. GUYS, LOOK AT THOSE HIGHS. THEY DON’T GET OUT OF THE 20S.
