Phillly Winter Weather Oulook

The current mild pattern will slowly revert back to more average December temperatures over the next several days.

A storm that had been expected to form over the weekend will probably pass off to our south,

The models are advertising a big change around Christmas Eve, with deep amplification of the jet stream, colder temperatures and possibly the development of a major storm. Stay tuned.

Philly Winter Weather Outlook

This weekend, we are entering into a period where the weather models are showing big differences in the forecast from run to run and between different models.

The upcoming weekend looks to be cloudy and wet, particularly on Saturday, but there’s a chance of a coastal storm developing anywhere in the time period from Sunday through early Tuesday.

It appears that it will be too warm here for snow. But while wet is much more likely than white, there’s even uncertainty about how amplified the jet stream may become and how much cold air will be present.

One thing that is becoming clearer….there is a change in pattern from last year’s highly amplified jet and oppressive cold weather, with extreme dry weather in the west.

This pattern reminds me of the last solar cycle peak in 2001 where we had very warm periods in January and February and more rain than snow.
