Enjoy the warmth while it lasts!

We are going to get an early taste of fall across southeast Wisconsin just in time for Labor Day. The rest of this week and the weekend will be mild and pleasant with highs in the upper 70s and lower 80s. After Sunday, we will start to see the jet stream pushing farther south into the upper Midwest, allowing for a strong cold front to bring some significantly cooler air into our area.

Note how the jetstream begins to dive south into Nebraska by Tuesday morning. This position of the jetstream will not only bring some cooler air into our area but also the chance for showers.


Here’s a look at possible temperatures by the afternoon on Labor Day; it looks like most locations will be in the 60s.


Tuesday afternoon looks like it will be even cooler with most areas in the 50s and 60s.

Now, we are not expecting any freezing temperatures during this brief cool snap but temperatures across the state of Wisconsin will range from the mid-30s to upper 40s on Wednesday morning. Note the pocket of mid-30s across northwestern Wisconsin in the image below.

We typically get our first freezing temperatures in southeastern Wisconsin between Oct. 1 and Oct. 20.

I’m sure the pumpkin spice lovers will be happy with the upcoming cooldown but for those who want to hold on to summer, you still have two more weeks until astronomical summer comes to an end.
