Frosty Nights, Chilly Days

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

Thank you for stopping by the Weather Watch 12 Blog!  Each day we strive to bring you the inside scoop on the current and future weather for our area.  We also love to hear your thoughts and questions in the comments section of the blog.

As advertised, the weekend started off blustery with cold temperatures and windy conditions.  Throw in a few sprinkles and brief showers, and it wasn’t the best day for outdoor activities.  The sprinkles and lake effect rain showers will continue on and off into Sunday, but should stay mainly into parts of Milwaukee, Racine, and Kenosha counties.

By early Sunday, inland areas will see clearing skies, and winds of 5-10 mph.  This will lead to overnight lows in the 30s and areas of frost.  As a result, Frost Advisories are in place Sunday from 1 a.m. to 9 a.m. for Fond du Lac, Dodge, Jefferson, Washington, Waukesha, and Walworth counties.  These locations could see lows in the low to mid 30s.

Clouds will keep areas close to the lake around 40 degrees.  A great illustration of this is from our high resolution computer model the RPM.  Below is a forecast satellite image from around 4 a.m. Sunday morning.  Notice the white over Milwaukee, Racine, and Kenosha…this represents clouds.  It will also be possible for a few sprinkles or showers to squeeze out of these clouds.

With the first frost upon us, the question often asked is, “Is this early for temperatures this cold?”.  Let’s look at the answer, below is the median date of the first 32 or lower temperature.  Notice Milwaukee usually see’s a 32 by October 18 or so, with the first week of October more typical for inland areas.  So this first push of cold air is about on time.

While Sunday morning will be cold, temperatures will likely drop into the upper 28-38 degree range across southern Wisconsin by Monday morning.  A good rule of thumb is to cover any plants or flowers you want to save, or bring them indoors the next 2 nights.

Finally, we always love to see viewer photos.  I received this picture on Saturday from Pete Vernon of Racine.  The lake clouds and showers along with a little sliver of sunshine produced a double rainbow!  Thanks for the picture Pete!

Make sure to watch WISN 12 News for the latest on any advisories, and your most accurate forecast.  Stay warm and have a great Sunday!

  1. While it got very cold up here last night in the Lomira area, we didn’t have much frost. We actually had a heavier frost about a week or so ago when the first frost advisory had been issued. There was very little frost this morning. The plants all survived last night.

    • Thanks, Cliff.

      Even colder tonight for you. You might touch the upper 20s.
