Next Weather: A dangerous explosion in the Arctic and chances of snow accumulation this week
PHILADELPHIA (CBS) – The next weather advisory is in effect Monday through Sunday as a dangerous cold snap and chances of snow accumulation move into the area this week.
On Sunday afternoon, a series of snow storm warnings ended after brief rounds of snow and gusty winds across southeastern Pennsylvania.
While some areas in the mountains may get some light accumulations, temperatures will rise into the mid-30s in the city, eliminating any chances of anything significant happening.
However, grassy surfaces and parked cars may pick up perhaps half an inch of paint. Any small amounts we get will disappear by mid-afternoon, with some sun returning as temperatures moderate slightly.
Furthermore, skies are expected to be generally partly cloudy and winds brisk for the rest of the day. High temperatures on Sunday will reach around 43 degrees before returning to the 20s overnight.
More snow follows
A cold snap has descended from the Arctic Circle across the Plains and Midwest. The cold air generated by this system will extend south into Texas, with some temperatures dropping to -43°C, and will slowly spread eastward.
Locally, we won’t see temperatures that cold, but we will experience below freezing temperatures and dangerous wind chills.
With this cold air, several storm systems will provide Philly with its first chance for snow accumulation in two years.
The snow moves in around 10pm on Monday and continues overnight until around noon on Tuesday, although the path and timing may change slightly before Monday night.
Currently, 1-3 inches is possible in the city, with a dusting at the beach and closer to 3-5 inches in the Poconos.
Some snow is possible on the commute early Tuesday resulting in slippery road conditions.
Dangerously cold temperatures
An arctic front moves in tonight, bringing with it a deep freeze that will stay with us until next Sunday. This will be our coldest stretch in several years.
Temperatures will drop into the teens and 20s tonight and Monday through Thursday temperatures will likely stay below freezing for about 96 hours. Wind chills will be in the teens and single digits this week and below zero in the Poconos.
The coldest days are Wednesday and Saturday, with maximum temperatures reaching 23 and 27, and lows reaching 16 and 18, respectively.
More snow late in the week
Another round of snow is possible Thursday night into Friday evening, and this storm could drop several inches of snow.
Timing and route may change, which could affect snow totals. The CBS Philadelphia NEXT Weather team will be tracking this storm throughout the week.
