THIS WEEK’S WEATHER

#Philadelphia #weather #PAwx

The current cold pattern will continue on Monday, but temperatures will slowly moderate through Christmas/Chanukah. as the current dip (trough) in the jet stream changes into a ridge—

No major active systems are expected, but several models are showing some light snow or flurries Tuesday morning, mostly in northern sections—

It looks like it will be cold enough for snow and at most only 0.5″ is currently forecast in these northern sections. (It should be noted that the latest ECMWF has some light snow further south but the AI version of the ECMWF shows no snow at all on Tuesday.)

The rest of the week is uneventful, with a gradual warmup. A system may bring rain the end of next weekend, possibly lasting through New Years Day.

When it comes to weather, things can change, so stay tuned.
