The Downward Spiral & Rain Chances

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

Thank you for stopping by the Weather Watch 12 Blog!  A big change is about to arrive in our area…just in time for the weekend.  In this entry we will look at the weekend, and also the annual downward spiral that accompanies Fall.

A few days ago in the blog I asked the question, ‘What is the date of the earliest 32 degree or lower temperature in Milwaukee?’  That poll question had a lot of responses, and 42% of those that answered chose the correct answer…September 20

So when is the average date of the first 32 or lower temeperature for our area.  The answer varies across southeast Wisconsin.  Counties near Lake Michigan see a frost later because of the proximity to Lake Michigan and the ‘warmer’ waters.  Here is the map showing the dates for the entire state.  This map is courtesy of the NWS.

With colder weather right around the corner, let’s take a look at how the average high begins to quickly dip in Milwaukee.  Below is the average high at Milwaukee’s Mitchell Airport for several dates.

  • September 17  72
  • October 1  67
  • October 15  61
  • November 1  53

While the average’s continue to drop, there will be warmer days sprinkled in too.  None of those warm days will occur this weekend though.  A cold front will sweep through the area early Saturday.  Near the front scattered showers will be possible.  Right now it looks like the best rain chance on Saturday will occur during the morning.  Remember, any slight chance in the position of the front, and some of the showers could linger into Saturday afternoon or evening.

Below is an image from our high resolution computer model showing the rain showers on Saturday morning.  I think they will be scattered, and fairly light. 

I’m heading to the Badger game in Madison Saturday afternoon and will at least throw a poncho in my car just in case.  But hopefully I won’t have to bring it into the stadium.  Temperature-wise this weekend, both days will see highs in the low 60s.  So get ready for a taste of Fall in the last week of Summer!

Finally, I was walking behind a row of trees in back of my house this week and came across some HUGE mushrooms.  The picture below shows a mushroom the size of a bowling ball!  If you have any idea what kind of mushroom this is please let me know.  There were about 6-10 of these growing back there.  Kind of strange!

Make sure to watch WISN 12 News for the updates!  Have a great weekend!

  1. That’s one huge mushroom! I wonder if it’s edible?

    • Lori,

      My kids were going crazy when we found it. I didn’t take a bite to find out if it was edible:)


  2. Jeremy – that isn’t a mushroom, that is Kansas hail. 😉

    • Nice! I found out it is a giant puffball mushroom. They are good to eat too!


  3. I’m the only dork around here who read mushroom, and immediately though Super Mario Brothers, aren’t I?
