***Watch WISN 12 News for the latest weather information!***

Thank you for stopping by the Weather Watch 12 blog.  If you missed yesterday’s blog on the cycling weather pattern, and how this week matches up with the end of December, check it out right after this entry.  It certainly is a must read!

How about the weather on Sunday!  Highs soared into the 40s for the first time since January 1.  Here is a look at some of the highs across the region from Sunday.

  • Port Washington  51
  • West Bend  47
  • Madison  46
  • Racine  45
  • Milwaukee 44
  • Sheboygan  43

If you remember just this past Thursday morning some all-time record low temperatures were shattered in parts of the Plains.  Nowata, Oklahoma set the all-time record low for the state at -31!  Just 3 days later the high on Sunday was 54…or an increase of 85 degrees in just over 72 hours!

Below is a look at the spread of temperatures across the Midwest on Sunday afternoon at 3pm.  Milwaukee was sitting at 43 degrees, while temperatures in southern Nebraska were in the mid 70s! 

Surface Temperatures Sunday 3pm

I think Sunday was a good test for southeastern Wisconsin for this upcoming week.  In my mind, if we could warm to 44 with a very deep snowpack, I think low 50s are possible on either Thursday or Friday as the warmest air moves over our area.

The warm air will be pushed east as a trough digs into the West.  The warmer southwest flow aloft is shown below in the GFS 500mb forecast map for Thursday morning.

500mb Thursday

If you like mild weather, you want a southwest flow in the winter.  Cold air does not reside over the Southwest, so that air being advected, or transported into Wisconsin will produce above average temperatures a majority of the time.

Some question marks do remain for this week, like when will the low clouds or fog move in, how much light rain will we see, and how quickly will a cold front arrive on Friday.  The answers will come as the latest data rolls in.  So watch WISN 12 News for the updates!

Have a great day and enjoy the mild week ahead!

  1. Cool! Despite my love for snow, I’m actually really looking forward to the warmup 🙂

    Jeremy, do you know if it’s possible to subscribe to comments on each new blog post, without having to first comment each time? I find everyone else’s comments to be interesting too. 🙂 Have a great week!

    • Dan,

      I’m not sure. Often when I’m logged into our blogging site I see a different format than a normal user. You could possibly use another email address to sign up and try. Just an idea. Let me know if it works.
