PHILADELPHIA (CBS) — A few quick disturbances with snow or rain showers are on tap both today and Monday night. A dusting of snow is possible in some places today.

Then a quiet mid-week as high pressure returns with sun and seasonal temperatures in the mid-40s.

A large winter storm arrives Thursday bringing temperatures in the upper 50s and rain with thunderstorms.

On Christmas, we could see either more rain or a mix or a quick burst of snow. This is all dependent on the arrival time of arctic air on the backside of the storm.

ECMWF and GFS Models agree on storm placement and a frigid Saturday, but they don’t agree on the timing of rain or possibly snow.

ECMWF is slower and has us in rain all of Christmas Day with a quick shot of snow Christmas night, north and west.

GFS is faster and brings cold air in faster for a change to snow early Christmas morning.

Saturday sunshine returns with a frigid day near freezing.
