Winter storm bears down on Pennsylvania, set to arrive late Wednesday, early Thursday - WGAL Susquehanna Valley Pa.

YOU’RE WATCHING DOUBLE DUTY GAIL NEWS 8 OR TRACKING YOUR NEXT WINTER STORM HERE ACROSS THE VALLEY. IT’S GOING TO QUICKLY BECOME INTERESTING BY OUR THURSDAY MORNING. WELCOME BACK. WE’RE ALMOST AT 520. THIS IS OUR LIVE GLANCING YORK NOW, LOOKING OUT TOWARD THE EAST. EVENTUALLY WE WILL SEE SOME SUN MIXED WITH CLOUDS AS WE HEAD THROUGH THE DAY, AS THEY START TO THICKEN UP AS THIS STORM SYSTEM MOVES EASTWARD, SUPER DOPPLER 8 EIGHT. SHOWING THOSE CLOUDS OUT TO THE WEST. BUT FOR NOW, MOST OF US ARE STILL SEEING STARRY SKY OUT THERE. BUT THERE’S ALL THE MOISTURE WITH THIS STORM SYSTEM STILL SEEING SOME TORNADO WARNINGS OUT ACROSS THE DEEP SOUTH. HEAVY RAIN. IT’S ALL MOVING IN OUR DIRECTION AND THAT’S WHAT’S GOING TO RUN INTO THE COLD AIR THAT WE HAVE IN PLACE NOW MAKING FOR A WINTRY MESS OF SNOW, SLEET, FREEZING RAIN AND EVENTUALLY RAIN. WE’RE AT SIX NEW ZEALAND’S GROVE AND YORK, SO BUNDLE UP OUT THERE, 3011 AND WE’RE AT 24 IN THE CAPITAL CITY AND 23 IN LANCASTER. OR WE’RE ONLY GOING TO GET INTO THE MIDDLE THIRTIES TO NEAR 40 THIS AFTERNOON. CHILLY FOR THIS TIME OF THE YEAR. TONIGHT, THAT’S WHEN WE START TO SEE THAT PRECIPITATION DEVELOPING LATE, ESPECIALLY WHERE THAT ICY MIX OF SLEET AND FREEZING RAIN WITH TEMPS, COLD IN THE MIDDLE TWENTIES TO NEAR 30. AND THEN TOMORROW WE’RE EXPECTING THAT SLEET AND FREEZING RAIN EVENTUALLY CHANGING TO SOME SNOW. AND THEN FINALLY A COLD RAIN AS THE WARM AIR WINDS OUT AS HIGH AS CLIMB FROM 36 TO AROUND 40. AND THAT MOISTURE COULD BE HEAVY AT TIMES. WE DO HAVE WINTER WEATHER ADVISORIES THAT HAVE BEEN ISSUED NOW FOR ALL OF THE VALLEY, JUST ABOUT THROUGH TOMORROW EVENING WITH THE WINTER STORM WATCHES STILL TO OUR NORTH AND WEST FOR THE HEAVIER AMOUNTS OF SNOW AND SLEET. THAT’S WHERE WE’RE GOING TO HAVE THE POTENTIAL FOR MAYBE SEVEN INCHES, FOUR OR FIVE TO POSSIBLY UP TO SIX INCHES AN HOUR FOR NORTHWESTERN NEIGHBORHOODS. HERE’S A PREDICTOR, 4:00 IN THE MORNING. WE’RE SEEING THAT MIX. THAT’S THE SNOW, THE SLEET, SOME FREEZING RAIN. AND YOU CAN SEE TEMPERATURE IN THE TWENTIES AND THIRTIES AS THE PRECIPITATION STARTS TO FALL HEAVILY. THAT’S WHEN WE START TO SEE THIS CHANGE OVER THE SNOW BY WHAT WE CALL DYNAMIC COOLING. WE’RE ACTUALLY SEEING THAT CHANGE FROM SLEET TO SNOW, SUBTRACTING HEAT FROM THE ATMOSPHERE. AND YOU CAN SEE THAT WHITE, THE BLUE, THAT’S THE SNOW THROUGH MID TO LATE MORNING THROUGH LUNCHTIME. AND IT CONTINUES TO FALL THROUGH THE CAPITAL CITY IN OUR NORTHERN COMMUNITIES THROUGH THE MID AFTERNOON WITH THAT RAIN SNOW LINE STARTS TO SHIFT NORTHWARD AS WE HEAD CLOSER TO THE EVENING DRIVE AND CLOSER TO DINNERTIME. I THINK FOR MOST OF US, BY EIGHT, 9:00, WE’RE SEEING MAINLY RAIN. BUT THAT DOES EXCLUDE OUR NORTHWESTERN COMMUNITIES WHERE WE’RE STILL GOING TO SEE SOME OF THAT MIX THROUGH THURSDAY NIGHT AND EARLY FRIDAY. THAT’S WHERE WE SEE THE PINKS AND THE PURPLES. THAT’S THE MORE MODERATE SNOWFALL ACCUMULATION, POSSIBLY CLOSE TO HALF A FOOT OR SO FARTHER TO THE SOUTH AND EAST, MAYBE AROUND LANCASTER IN NEW YORK, MAYBE AN INCH. AND THAT’S A PRETTY MAYBE OF THE SNOW IN THE SLEEP. BUT ICE IS A BIGGER CONCERN FOR US. AND WE CAN SEE SOME ICE ACCRETION, MAYBE A 10TH OF AN INCH OR SO IN SOME SPOTS OF THAT FREEZING RAIN UNDER, THE SNOW AND SLEET. SO THAT COULD MAKE SOME REALLY TRICKY TRAVEL TOMORROW. AND THAT’S WHERE WE’RE GOING TO FIND THE WORST OF THE TRAVEL FROM THE MORNING DRIVE THROUGH MIDDAY. IT DOES START TO IMPROVE BY THE EVENING AS TEMPERATURES DO WARM ABOVE FREEZING. SO, AGAIN, MAKE SURE YOU HAVE WGAL NEWS APP DOWN THERE. YOU TRACK ALL OF THIS IN THE PALM OF YOUR HAND. AND OF COURSE, WE’LL BE GETTING EVERYTHING OUT AS QUICK AS WE CAN ON AL.COM AND ON TO SOCIAL MEDIA. OUR NEWEST STORM DOING TEN DAY SHOWS ALL THIS WINDING DOWN FRIDAY SO COULD HAVE SOME LIGHT RAIN OR SNOW. I THINK BY LUNCHTIME. AND WE’RE SEEING SOME SUNSHINE TAKING BACK OVER AT LEAST A LITTLE BIT OF IT. SATURDAY COULD HAVE SOME FLURRIES OR SNOW SHOWERS AS UPPER LEVEL PART OF THIS STORM SYSTEM MOVES ON THROUGH SUNDAY. EVEN COLDER A LITTLE BRISK OUT THERE AS HANUKKAH BEGINS OR IN THE MIDDLE THIRTIES. AND WE STAY CHILLY THROUGH OUR HOLIDAY WEEK. WE’RE BACK THE UPPER THIRTIES THAT MONDAY AND TUESDAY. WINTER OFFICIALLY BEGINS ON WEDNESDAY AND THEN COULD HAVE SOME MORE WINTRY WEATHER THERE PULL POSSIBLY THURSDAY NIGHT IN THE FRIDAY OF NEXT
