Good Start, Bad Finish To Holiday Weekend?

***Watch WISN 12 News for the latest weather information all weekend long!***

Happy holiday weekend!  Thank you for stopping by the Weather Watch 12 blog.  Lots of good news weatherwise in the weekend forecast.  However, a cold front will push into the region, and this front will likely produce a few rain showers.  In this entry we will talk about the weekend from start to finish, and also look at the time window when showers may fall.

Before we chat about the weekend, I want to remind everyone how you can stay updated with the Weather Watch 12 forecast all weekend, even if you are on the go!

Let’s start with the good, and let me tell you, the good far out weighs the bad this weekend.  On Saturday, we should enjoy nearly 100% sunshine!  Temperatures will climb into the 80s inland, but an east to southeast wind of 6-13 mph near Lake Michigan will keep areas close to the lake in the mid-70s.

Below is the forecast temperature map for 1 p.m. Saturday.  Notice the 80s poking into parts of southern Wisconsin.  Just click on the map to enlarge.

The weather should remain very quiet heading into Sunday.  With high pressure shifting to the East, and a cold front approaching, winds will turn to the south on Sunday.  This means the lake breeze will be kept offshore for part of the day.  As a result, highs should soar into the 80s!  Low to mid 80s in Milwaukee, with possibly 87 degrees well inland.

Below is the surface forecast map from the HPC for Sunday.  The cold front looming to the west may spell trouble for Monday!

The cold front will pay southern Wisconsin a visit early Monday.  This means the best chance of rain showers over the next 3 days will be on Monday.  The highest chance of rain on Monday will occur during the morning hours.  If you have outdoor plans, please don’t cancel them, but do have an alternate plan ready.

The showers should be scattered, nothing severe looking at this point, but rain is rain and can spoil the best made plans.  To give you a ROUGH ESTIMATE of the rainfall expected, here is just one model forecast for Monday.

Below is the 24 hour rainfall forecast from the 18Z NAM(North American Model).  The darker green shade represents rain totals of 0.25″ to 0.50″.  At this point I think most areas should stay under 0.25″.   

We will continue to track the cold front and possible rain chance all weekend long on WISN 12 News, and right here in the blog. In the meantime, grab your sunglasses and sunscreen and enjoy the sunshine on Saturday and Sunday!  If you have questions, please post them to the comments section of the blog!

Have a happy and safe holiday weekend!

  1. I’m going to be marching in a parade Monday morning……how do you think the forecast looks for this?

    • Robert,

      There is a chance of showers from Monday morning into the early part of the afternoon. Hopefully your area stays dry, but scattered showers look like good bet on Monday.
