AND TEMPERATURES WILL BE MILDER. THEY’RE GOING TO BE THE WARMEST OF THE WEEK IN THE LOWER 40S. NOW ON FRIDAY, HERE COMES A DRY BOUNDARY. THAT’S THE ARCTIC AIR. AND THE WIND WILL PICK UP FRIDAY AFTERNOON, USHERING IN THAT ARCTIC AIR JUST IN TIME FOR THE WEEKEND. SO WITH THAT ARCTIC AIR IN PLACE, YOU CAN SEE THE ARCTIC HIGH OVER THE NORTHEAST THAT’S GOING TO HOLD OFF THE STORM JUST A LITTLE BIT. TIMING IS STILL IN QUESTION ON SUNDAY, WHERE THIS SNOWSTORM STARTS. IS IT SATURDAY NIGHT? IS IT SUNDAY MORNING? WE’RE STILL WORKING ON THOSE DETAILS, BUT THE CONFIDENCE IS GROWING. THAT LOW PRESSURE WILL MOVE OFF THE MID-ATLANTIC COAST, PUTTING US IN THAT SWEET SPOT FOR SNOW. SO WE ARE LOOKING AT A PLOWABLE SNOW ON SUNDAY. POSSIBLY COULD BE SOME HIGHER TOTALS. WE WILL KEEP YOU POSTED AS TOTALS WILL COME OUT ON FRIDAY AND WE WILL HAVE BETTER DETAILS AS HIGHER RESOLUTION MODELING COMES IN OVER THE COMING DAYS. BUT BEHIND THAT STORM, IT’S JUST GOING TO BE DOWNRIGHT FRIGID. SO IT’S GOING TO BE HARD TO GET CLEANED UP FROM THE STORM BECAUSE TEMPERATURES WILL BE SO COLD. SO HERE’S WHAT WE KNOW ARCTIC AIR IS IN PLACE. PRECIPITATION WILL BE ALL SNOW SUNDAY, POSSIBLY LINGERING INTO MONDAY MORNING. AND THEN THIS IS A PLOWABLE SNOW. IT’S LIKELY HIGH TOTALS ARE POSSIBLE AND THE SNOW IS GOING TO BE VERY LIGHT AND FLUFFY. IT’S NOT GOING TO BE THAT HEAVY, WET SNOW THAT WE SAW OVER THE WEEKEND. ROAD CONDITIONS. YOU CAN EXPECT SNOW COVERED ROADS EASILY. THAT’S A LOCK. TRANSIT DELAYS WILL BE HIGH, COULD HAVE SOME LOW VISIBILITY IF THE SNOW COMES DOWN AT A HEAVY CLIP, BUT THAT REMAINS TO BE SEEN. AND THEN POWER OUTAGE CHANCE LOW. NOT EXPECTING MUCH WIND WITH THIS STORM. IT’S NOT A NOR’EASTER OR A CLASSIC WINDSTORM WITH THE SNOW. AS FAR AS OUR CONFIDENCE GO. ALL SNOW. I THINK THAT’S A LOCK FOR US. TIMING. WE’RE MODERATELY CONFIDENT ON THAT SUNDAY INTO MONDAY, AND THEN THE TRACK MODERATELY CONFIDENT TRACK THAT IT MOVES OFF THE EAST COAST, BUT TOTALS STILL LOW BECAUSE WE DON’T HAVE THAT HIGH RESOLUTION DATA UNTIL WE GET TOWARD THE END OF THE WEEK. HERE’S A LOOK AT OUR TEN DAY FORECAST. TEMPERATURES THAW OUT NEXT COUPLE OF DAYS JUST A LITTLE BIT, BUT THEN WE REALLY SEE THE SURGE OF ARCTIC AIR, WHICH OOPS SORRY ABOUT THAT, STAYS IN PLACE AS WE HEAD INTO THE WEEKEND AND BEYOND INTO NEXT WEEK. SO THAT’S REALLY THE KEY. REGINA CONSIDERING, YOU KNOW, WE GET SOME SNOW ON SUNDAY THAT’S GOING TO REALLY GIVE US COLD TEMP
