One Cold Day, More On Deck

***Watch the winter forecast on WISN 12 News Tuesday at 10pm!***

Thank you for stopping by the Weather Watch 12 Blog!  I’m getting very excited for next Tuesday, as our winter forecast will be issued! 

Until then, there is plenty to talk about as we have lots of ups and downs in the forecast.  The first drop in temperatures will greet us on Saturday.  The coldest air with this push will stay just to our north, but highs in the 30s can be expected on Saturday.  A cold start to the gun-deer season in Wisconsin, but certainy nothing uncommon for this time in November.

Below are the surface observations at 5:43pm Friday.  A couple things of note, the cold front was right near Milwaukee as temps were in the 40s with winds just turning to the west, but behind the front, readings were only in the single digits in Devils Lake, North Dakota!

 

This is a sign of the cold air beginning to build near the U.S. and Canadian border, and all we need is a storm to dislodge a chunk of this very cold air!

2 storm systems are possible in our region in the next 6 days.  The first will arrive Sunday and Monday.  The center of low pressure will track very likely west of Milwaukee.  As discussed in the blog before, this generally means all rain for our area.  A few showers are possible both Sunday and Monday, along with milder high temperatures in the 50s.

Storm #1 will draw in colder air, but the potential for a second storm around Wednesday or Thanksgiving Day will likely draw in the coldest air of the season.  If you remember, back on November 10 in the blog I mentioned that a cold snap was possible on Thanksgiving!

Right now I’m confident that highs will drop into the 20s either on Thanksgiving or the following day.  The big question is will it snow, and how much?  That will take longer to answer, so look back for updates all weekend with the latest data.

I’ll leave you on this blog with the forecast temperature map from the 12Z GFS for late Thanksgiving Day.  Yikes!  20 to 25 degrees over much of southeast Wisconsin.

We will continue to monitor the latest data and have updates on WISN 12 News!

Have a great weekend!

  1. I can’t wait to see what the NAM has to say on the matter.

  2. 50 degrees on Wednesday with rain. Nothing more than flurries for Thanksgiving.

    • Patrick,

      If the surface low/upper low stays to our northwest then Wednesday would be warmer and most of the snow would stay northwest too. That is why we have said all along the storm track is not set. Personally I never like to put snow amounts on a forecast much more than 48 hours in advance. How this storm tracks will give us a good idea for when it returns later in the winter.
