CONTROL OF GREENLAND. I’M JENN SULLIVAN, REPORTING. NOW, THE WGAL NEWS EIGHT STORM TEAM FORECAST WITH METEOROLOGIST RYAN ARGENTI. EXPECTING SOME MORE SNOW AS WE HEAD INTO TONIGHT AND ALSO INTO EARLY TOMORROW MORNING. WE’RE WATCHING SOME SNOW ALREADY BEGINNING TO BUILD INTO PORTIONS OF WEST VIRGINIA, MOVING INTO THE COMMONWEALTH HERE SOON, MOVING WEST TO EAST. AFTER 1:00 IN THE MORNING, WE’LL START TO SEE SOME OF THAT SNOW DEVELOP, STARTING TOWARDS OUR WESTERN COUNTIES. SO IMPACT NIGHT TONIGHT FOR SOME OF THAT SNOW TO ARRIVE, THEN LIGHT TO MODERATE SNOW EARLY SUNDAY THEN LINGERING UNTIL THE EARLY AFTERNOON. FOR OUR EASTERN COMMUNITIES, WE DO HAVE AN IMPACT WARNING SET FOR US FOR SUNDAY. AND THEN ONCE WE GET TO OUR TUESDAY, WE’RE GOING TO BE SEEING SOME SUBZERO CHILLS FOR THE FOR THE MORNING TIME. IT’S GOING TO BE THE COLDEST MORNING OF THE WEEK SO FAR. SO LOOK AT THE TEMPERATURES RIGHT NOW. WE’RE INTO THE 20S FOR OUR EASTERN AREAS. YOU CAN SEE LANCASTER, HARRISBURG AND LEBANON GETTING RIGHT INTO THE LOWER TO MID 20S RANGE. BUT YOU SEE SOME OTHER COMMUNITIES SEEING MORE. SO 34 AND 35 DEGREES TOWARDS GETTYSBURG AND CHAMBERSBURG. THAT’S ALL BECAUSE WE HAVE SOME OF THAT SNOW PACK THAT IS THAT PRETTY MUCH FELL DOWN TOWARDS, ESPECIALLY TOWARDS OUR EASTERN COMMUNITIES. THAT’S ALLOWING FOR TEMPERATURES TO BE COLDER OR LOWER THAN THAN THE OTHER AREAS OR SOME OTHER COMMUNITIES THAT DIDN’T REALLY SEE SO MUCH OF THAT SNOW EARLIER TODAY. SO SEEING SOME OF THOSE 20S ACROSS THE AREA AND ALMANAC FOR THE DAY TODAY FOR HARRISBURG INTERNATIONAL AIRPORT RIGHT AROUND 38 DEGREES AT ABOUT A HALF INCHES OF SNOWFALL RECORDED AT THE AIRPORT, I WILL POINT OUT, HAVE BEEN MONITORING SOME OF THE SKY CAMS WE I AM STARTING TO SEE SOME FOG DEVELOP ACROSS THE AREA, SO IF YOU HAPPEN TO BE TRAVELING OVERNIGHT OR IF YOU IF YOU ARE TRAVELING TONIGHT AT ALL, I’M SURE YOU’RE FIGHTING THE PILLOW RIGHT NOW. BUT IN TERMS OF THE FOG, WE ARE LOOKING AT ABOUT ABOUT A MILE AND THREE QUARTERS, ALMOST A TWO MILE VISIBILITY. SEEING SOME OF THAT FOG DEVELOP IN SOME SOME COMMUNITIES. SO ESPECIALLY IN AREAS THAT RECEIVE SOME OF THAT SNOW TODAY MIGHT SEE SOME FOG DEVELOP. BUT SPEAKING OF THE SNOW, LET’S CHAT ABOUT THAT. SO WE’RE GOING TO SEE SOME OF THAT SNOW DEVELOP AFTER 1 A.M. MOVING WEST TO EAST TEMPERATURES RIGHT AROUND THAT 24 TO 30 DEGREE RANGE A WIDE RANGE. TONIGHT WE’LL HAVE A NORTHWESTERLY BREEZE BETWEEN 5 AND 10MPH. SO IMPACT NIGHT TONIGHT LEADING INTO TOMORROW MORNING FOR LIGHT TO MODERATE SNOW. WE’LL BE SEEING A COATING TO THREE INCHES OVERALL, BUT THE MOST OF THAT SNOW EXPECTING TO SEE CLOSER TOWARDS LANCASTER AND YORK COUNTIES 26 TO 32 DEGREES FOR THE MORNING, THEN JUMPING UP TOWARDS RIGHT AROUND THE FREEZING MARK. ONLY 32 DEGREES, BUT THAT SNOW WILL BEGIN TO TAPER BY NOON, AND WE’LL START TO SEE SOME OF THAT CLEARING LATER IN THE EVENING AS WE GET INTO AS WE GET INTO TOMORROW. BUT PRECIPITATION TIMELINE TONIGHT INTO SUNDAY. LIGHT SNOW, THEN TURNING A LITTLE BIT MODERATE BY THE TIME WE GET TO OUR SUNDAY MORNING. THEN WILL BE ENDING EAST AND THEN WE’LL START TO DRY OUT TOWARDS SUNDAY EVENING. BUT I WILL SAY AND MENTION THE POTENTIAL ROAD CONDITIONS. WE’LL BE SEEING SOME SNOW COVERED ROADS OVERNIGHT TONIGHT INTO TOMORROW MORNING, AND THEY’LL BE WET TO SLUSHY FOR OUR EASTERN AREAS. BUT LIKE I MENTIONED PREVIOUSLY, WE’LL BEGIN TO DRY OUT TOWARDS THE EVENING, SO LET’S TIME IT OUT FOR YOU SO THAT SNOW STARTS TO BUILD IN CLOSER TO 1:00 IN THE MORNING. SO IN THE NEXT COUPLE OR FEW HOURS HERE, WE START TO SEE THAT SNOW BUILD IN. BUT THEN ONCE WE GET CLOSER TOWARDS THREE, FOUR, 5:00 IN THE MORNING, THAT’S WHEN WE’LL START TO SEE SOME MORE OF THAT SNOW BEGIN TO OVERSPREAD OUR SOUTH AND EASTERN COMMUNITIES, ESPECIALLY TOWARDS LANCASTER AND YORK COUNTIES. AND THEN ONCE WE GET TO CLOSER TO ABOUT 11:00, 12 NOON, THAT’S WHEN WE’RE GOING TO START TO SEE THAT SNOW BEGIN TO COMPLETELY MOVE OUT. STILL SEEING SOME LINGERING CLOUDS FOR THE EARLY AFTERNOON, THEN CLEARING. BY THE TIME WE GET TO THE EVENING. BUT IN TERMS OF OUR OVERALL SNOWFALL, YOU CAN SEE PREDICTOR IS HIGHLIGHTING FOR US CLOSER TOWARDS YORK AND LANCASTER COUNTIES. SEEING THE MOST OF THAT SNOW FOR OUR AREA. BUT YOU CAN SEE ON STORM TEAM LIVE RADAR NETWORK ZOOMING OUT YOU CAN SEE SOME OF THAT SNOW ALREADY BEGINNING TO BUILD IN TOWARDS THE COMMONWEALTH. BUT JUMPING AHEAD INTO TOMORROW EVENING ALREADY TALKED ABOUT THE TIMING FOR THE SNOW. HERE’S THAT CLEARING FOR TOMORROW EVENING RIGHT AROUND 8:00 AND WE’LL SEE MORE OF THAT CLEARING PERSIST. GETTING INTO MONDAY NIGHT INTO EARLY OR EXCUSE ME, SUNDAY NIGHT INTO EARLY MONDAY MORNING. WE’LL SEE SOME PARTLY SUNNY CONDITIONS DEVELOP, BUT NOT ONLY PARTLY SUNNY CONDITIONS, VERY BLUSTERY CONDITIONS. IT’S GOING TO BE GETTING WINDY FOR BOTH MONDAY AND TUESDAY. LOOK AT THIS. TEMPERATURES ONLY GETTING DOWN TO 22 DEGREES FOR YOUR TUESDAY IMPACT DAY SET FOR TUESDAY FOR SUBZERO MORNING. WIND CHILLS WILL BE AGAIN. BELOW ZERO IS WHAT IT’S GOING TO FEEL LIKE FOR OUR TUESDAY.
