Good evening, everyone. The weather over our Christmas weekend continues to look well behaved with rain and milder temperatures dominating. The pattern into next week continues to take a turn toward more winter on the models.

You know all about the weekend… blah, blah blah. Let’s focus on what comes behind that next week.

We are likely to see another storm system rolling across the region. Milder air comes in ahead of it, but much colder air shows up behind it.

In a rare show of solidarity, we find the European and GFS models on the same page.

That’s a decent shot of cold for the second half of next week, with wraparound snow showers and flurries.

Both models then follow that up with an arctic front by New Year’s Eve and Day.

This is a pattern that, if the operational models are correct, could really turn harsh across the country. Watch  the blocking going up near Alaska and how it tries to hook up with a block coming across Greenland…

That would force a deep trough with arctic air to take over much of the country. But is that setup correct? I’m torn right now because the Ensembles aren’t showing this quite to the extent we are seeing with the operational models.

If we take the Analog years into consideration, they would be on the side of the operational runs.

Enjoy your evening and take care.
