Updated Saturday 02/07/26 @ 9:15 PM — Cold weather continues through Sunday with high temperatures again just reaching the upper teens. Wind chills, still low, will be somewhat better than Saturday.

By Tuesday and Wednesday, temperatures moderate to the upper 30s as two disturbances shear off to our north and south. Little if any precipitation is expected except in far southern portions of the Delaware Valley.

Much of the rest of next week is transitional to somewhat closer to average temperatures, but still colder than averages. The graphics from last Thursday capture the changes.

The AI models are hinting at a major mixed precipitation storm next weekend. As has been the case with the longer range forecasts over recent weeks, these storm forecasts have not been overly consistent. But this system bears watching.


Cold!

There’s been little change in the snow accumulation forecast with just a dusting to 0.5” possible in the Delaware Valley.

Low pressure developing off the coast along with high pressure building in will cause a pressure gradient resulting in winds gusting to near 40 mph late Saturday with resultant wind chills below zero late Saturday into Sunday.

Temperatures rebound above freezing by Tuesday.
The possibility of a major storm exists for Wednesday but the latest ECMWF-AI and AIGFS splits the energy into northern and southern components, thus sparing our area from another assault. But I’m watching this closely.
