Light snow is expected to develop overnight into Sunday morning; subzero wind chills expected Tuesday morning
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 LATER TONIGHT INTO TOMORROW MORNING. SO WE’RE LOOKING AT SNOW DEVELOPING WEST TO EAST AFTER 1:00 IN THE MORNING. THAT’S THE TIMING THAT WE’RE EXPECTING. AND THEN LIGHT TO MODERATE SNOW WILL BE EXPECTED FOR EARLY SUNDAY, LINGERING UNTIL THE EARLY AFTERNOON. I CUT IT OFF RIGHT AROUND 12 NOON FOR SUNDAY, BUT WE’RE GOING TO BE SEEING SOME SNOW COVERING THE ROADWAYS AS WE GET INTO TOMORROW. THEN AFTER THAT, WE’RE LOOKING AT SUBZERO CHILLS, SUBZERO WIND CHILLS TUESDAY MORNING WITH THE COLDEST MORNING OF THE WEEK. THAT’S WHAT’S GOING TO BE COMING UP FOR THE FOR THE BEGINNING OF THE WORKWEEK. YOU SEE TEMPERATURES INTO THE 30S, 32 IN YORK, 33 IN CARLISLE, 29 IN HARRISBURG. SO PRETTY COLD OUT THERE. WE’RE GETTING PREPPED FOR THIS NEXT SYSTEM THAT’S GOING TO COME THROUGH. ALMANAC FOR THE DAY TODAY HIT A HIGH OF 38 DEGREES, BUT THAT’S RIGHT AROUND PAR FOR THIS TIME OF THE YEAR. AND EARLIER THIS MORNING HIT RIGHT AROUND 28 DEGREES. 23 IS WHAT WE EXPECT FOR FOR THIS TIME OF YEAR. HAD ABOUT A HALF INCH OF SOME SNOW FALL AT HARRISBURG INTERNATIONAL AIRPORT, BUT MORE SNOW IS ON THE WAY, SO LET’S GET RIGHT INTO IT. INCREASING CLOUDS AS WE HEAD INTO THE EVENING WITH LIGHT WINDS 32 DEGREES. THEN FOR TONIGHT, DROPPING DOWN TO THE UPPER 20S. THIS IS WHEN WE START THE IMPACT PERIOD. SO RIGHT AFTER 1 A.M. THAT’S WHEN WE’LL START TO SEE SOME OF THAT SNOW BEGINNING TO DEVELOP AND SPREAD ACROSS THE AREA HEADING INTO TOMORROW, LOOKING AT SOME LIGHT MORNING SNOW. AND IT BEGINS TO TAPER MORE TOWARDS OR BEGINS TO TAPER EAST. ONCE WE GET INTO THE AFTERNOON TEMPERATURES RIGHT AT THAT FREEZING MARK AT 32 DEGREES. SO IMPACT DAYS FOR OR IMPACT NIGHT AND AN IMPACT DAY OR IMPACT MORNING. I SHOULD SAY FOR YOUR SUNDAY. BUT YOU CAN SEE THE PRECIPITATION TIMELINE FOR TONIGHT AND SUNDAY. LIGHT SNOW EXPECTED FOR OVERNIGHT SUNDAY MORNING BECOMING LIGHT TO MODERATE. THEN THAT SNOW WILL BEGIN TO END EAST AND AND START TO DRY OUT ONCE WE GET TO SUNDAY EVENING. BUT THE ROAD CONDITIONS ARE GOING TO GET DICEY OUT THERE. THEY’RE GOING TO BE SNOW COVERED FOR TONIGHT, SNOW COVERED FOR YOUR SUNDAY MORNING. SO THOSE WHO ARE GOING OUT TO SUNDAY MORNING SERVICES, BY THE WAY, PAY ATTENTION TO THE ROADS. THEY COULD BE SNOW COVERED ROADS MAY ALLOW FOR SOME MODERATE TRAVEL IMPACTS FOR THE MORNING, BUT THEN WE START TO GET WET TO SLUSHY TOWARDS OUR EASTERN AREAS EARLY SUNDAY AFTERNOON. THEN WE’LL START TO DRY OUT FOR SUNDAY EVENING. SO LET’S TIME THINGS OUT FOR YOU. SO WE’LL BEGIN TO BUILD IN THE CLOUD COVER LATER ON THIS EVENING INTO TONIGHT. YOU CAN SEE PREDICTER HIGHLIGHTING THAT FOR US FOR THE ENTIRE AREA. THEN ONCE WE GET TO RIGHT AROUND 1:00 IN THE MORNING, HERE’S THE START TIME. STARTING TO SEE SOME OF THAT LIGHT SNOW TOWARDS OUR FAR NORTHWESTERN COMMUNITIES. ALTHOUGH THE MOST SNOW THAT WE’RE EXPECTING IS GOING TO BE TOWARDS OUR EASTERN COMMUNITIES, ESPECIALLY TOWARDS LANCASTER AND YORK COUNTIES, YOU CAN SEE SOME OF THAT SNOW BEGINNING TO BUILD IN FROM THE SOUTH STARTING AT 3:00, AND EVENTUALLY YOU COULD SEE THERE YOU MAY HAVE A BIT OF A START OF, OF A WINTRY MIX, ESPECIALLY TOWARDS LANCASTER AND YORK COUNTIES. BUT ONCE WE GET TO ABOUT 4 OR 5:00 IN THE MORNING, STARTS TO SWITCH OVER TO ALL SNOW, YOU CAN SEE PREDICTORS HIGHLIGHTING THAT FOR US THAT PERSISTS THROUGH THE MORNING ENDING RIGHT AROUND 11:00 IN THE MORNING, I PUT A STOP AT RIGHT AROUND 12 NOON FOR SUNDAY, BUT THEN WE’LL SEE SOME RESIDUAL CLOUDY CONDITIONS. MAY SEE A SPOTTY SNOW SHOWER OR RESIDUAL SNOW SHOWER AS THAT SYSTEM PUSHES OFF TOWARDS OUR NORTHEAST. SO EXPECT THAT AS WE GET INTO AS WE GET INTO TOMORROW. SO HERE’S STORM TEAM LIVE RADAR NETWORK NOT SEEING ANY ACTIVE SNOW RIGHT NOW, BUT JUST A PLAN. SOME THINGS OUT FOR YOU AS WE GET INTO OUR SUNDAY EVENING, WE’LL START TO SEE SOME CLEARING AS WE GET INTO OUR SUNDAY NIGHT. THEN STARTING FOR OUR MONDAY, SEEING SOME PARTLY SUNNY CONDITIONS DEVELOP. BUT THEN THE STORY HERE IS THIS COLD FRONT. THAT COLD FRONT PASSED BY THAT’S GOING TO ALLOW FOR BLUSTERY CONDITIONS TO BEGIN AND REALLY START US OFF FOR THE WORKWEEK. VERY, VERY CHILLY, VERY COLD CONDITIONS AND EVEN COLDER AS WE GET INTO OUR TUESDAY. WE HAVE TUESDAY AS AN IMPACT DAY FOR THE SUBZERO MORNING. WIND CHILLS, TEMPERATURES ONLY GETTING RIGHT AROUND 22 DEGREES FOR YOUR TUESDAY. SO THAT’S ALSO WHAT WE’RE EXPECTING FOR THESE NEXT COUPLE OF IMPACT DAYS. BUT THEN GETTING INTO THE REST OF THE WORKWEEK FOR YOUR WEDNESDAY, GETTING INTO THE NEXT WEEKEND. BRISK AND CHILLY FOR YOUR WEDNESDAY. WE ARE TRACKING A FEW MORE SNOW SHOWERS FOR YOUR THURSDAY. FRIDAY IS CHILLY, THEN BRI
