Big changes by the end of the week

Good Monday, folks. We have big changes working our way for the end of the week and the weekend. A big temperature plunge might lead to our first taste of winter weather later in the weekend.

Highs Monday will range from the mid- to upper 50s in many areas. Clouds will increase and there is a small threat for a shower in the southeast.

Another weak system moves in Tuesday and Wednesday with a small chance of a shower. After that, the fun begins.

Ahead of this system, our highs head toward 70 by late Thursday and Friday on a gusty southwesterly wind. As the front slams in early Saturday, temps will start to tank and the numbers will keep dropping through Sunday. That’s when highs are likely to be in the 30s.

Here’s the European model for Friday morning, Saturday morning and Sunday morning:

Here’s a different look at the same model run in six-hour increments. Notice how northwesterly winds try to bring snow showers and flurries in here:

The Canadian model is also seeing the wrap-around snowflake potential:

The models are also showing a clipper looking system diving in late Tuesday into the busy travel day before Thanksgiving:

The Canadian is picking up on some flakes with that:

Again, that’s 10 days away so take that with a ginormous grain of salt. Still, it shows the trend of a potential early start to winter.

Thanksgiving week on the GFS Ensembles has a very cold look. Here is the average temperature departure in Celsius for the entire week:

Make it a great day and take care.
