Hour-by-hour snow projections for South-Central PA

OFF TO OUR NORTHEAST. THIS AREA OF LOW PRESSURE OVER THE GREAT LAKES IS STARTING TO DIE OFF, BUT IT’S GOING TO KICK A LOT OF COLD AIR OUR WAY TO GENERATE THAT SNOW. AS WE HEAD INTO TOMORROW. SO HERE’S WHAT THE PREDICTOR SHOWS. TODAY WE START OUT WITH A SUN. THEN WE SEE INCREASING CLOUDS AND A COUPLE OF SHOWERS IN THE AFTERNOON AND EVENING. TONIGHT THERE COULD BE SOME PARTIAL CLEARING, BUT NOT FOR LONG. BY TOMORROW MORNING, CLOUDS FILL BACK IN AND SOME LIGHT SNOW DEVELOPS FROM NORTH TO SOUTH THROUGH THE MORNING HOURS. ROADS WILL BE WET AND THEN IN THE AFTERNOON THOSE SNOWFLAKES MIX WITH RAIN WILL BE UP TO ABOUT 40 FOR OUR HIGH TEMPERATURE. ALL OF THAT RAIN HITS THE ROAD LATE ON FRIDAY NIGHT AND THEN SATURDAY IS LOOKING MAINLY DRY. CAN’T RULE OUT A COUPLE OF TRAILING SHOWERS. I DO SEE CLOUDS HANGING TOUGH ON SATURDAY THOUGH, WITH HIGHS CLOSE TO 50, SO PREDICTOR ESTIMATED SNOWFALL TOTALS. YOU SEE AT ELEVATION YOU’RE GOING TO DO BETTER. I FAVOR AREAS, ESPECIALLY OUT TO OUR WEST NEAR JOHNSTOWN AND SOMERSET FOR SOME HIGHER TOTALS. EVEN IN PARTS OF NORTHERN LEBANON, DAUPHIN AND SCHUYLKILL COUNTIES ABOVE 1500 FEET, YOU COULD PICK UP AN INCH OR TWO AT ELEVATION. SO HERE’S A LOOK AT OUR TEN DAY FORECAST. WE HAVE 48 DEGREES FOR THE HIGH TODAY, 40 TOMORROW. COOLEST DAY OF THE WEEK. WE’RE UP TO 50 ON SATURDAY, 52 FOR SUNDAY AND NEXT WEEK WE START IN THE 50S BUT END UP IN THE 40S WITH A SYSTE
