After a brief reprieve, an active, colder weather pattern settles in for the upcoming days, forecasters say.
While innocuous flurries are possible throughout the area Saturday, a more robust system may deliver snow in about a six hour period Sunday, with the most in northern areas, according to the National Weather Service.
“One to possibly as much as four inches of snow is expected Sunday afternoon and evening,” a Hazardous Weather Statement from the service advises. “Untreated, unplowed surfaces should become hazardous for a few hours.”
The late Saturday morning forecast discussion issued by the service notes that a snow advisory may be necessary for areas north of Interstate 78 and possibly down to near Philadelphia.
Skies will clear Sunday night, then the next snow threat looms for Wednesday night into Thursday, but it is not a certainty.
While forecasters expect a coastal low pressure system to move along the Mid-Atlantic coast, “this particular midweek event is not a lock nor is it a lock to be snow,” the forecast discussion advises. Details will emerge over the coming days.
What is more certain is a brief stretch of unseasonably cold temperatures.
Temperatures will be about 10 degrees below normal Sunday, five below normal Monday, then nearly 15 degrees below normal Tuesday and Wednesday, according to the National Weather Service. Temperatures then return to near normal Thursday and slightly above normal Friday.
