***Watch WISN 12 News for the latest weather information!***
Thank you for stopping by the Weather Watch 12 blog! The weekend is here! And overall I think weather conditions should be okay for Saturday and Sunday. Not perfect, but we’ll call it ‘nice’.
Before we talk about the weekend, let’s take a look back to a huge temperature spread that occurred across southeast Wisconsin on Friday. Around 3pm a southeast wind was keeping lakeshore locations cooler. Port Washington was 53 degrees, Milwaukee 74, and Madison a record tying 91 degrees!
Below is the surface map at 3:43pm Friday. Just click on it to enlarge. The temperatures are in red, and the wind barbs give a good indication of why Milwaukee was cooler than surrounding inland locations.
Moving forward the focus is on rain chances through early afternoon Saturday. While I think a few showers or isolated t-storms will occur in southeast Wisconsin, the chances don’t look very impressive.
Below is the GFS computer model forecast for 1pm Saturday. The green shades indicate precipitation, and the darker the green the heavier the model is forecasting the precipitation to be. With that said, as a cold front passes by our area on Saturday, a few showers are possible, but it does not look like a widespread heavy rain by any means.
The threat for showers will exit most of the area by 1-3pm. If the cold front slows down locations near the WI/IL border may see a t-storm or two nearby during peak heating in the afternoon. Severe weather potential looks to stay mainly in Illinois for Saturday.
As for temperatures, winds will be southwest to northwest, meaning the lake breeze should stay offshore for much of the day. Lakeshore locations should warm into 70s or lower 80s!
By Sunday, the winds will swing around to an easterly direction so it will be much cooler near the lake. Likely around 70 in Milwaukee, but I wouldn’t be surprised if temperatures dropped back into the 60s right along the lake. Again it will be warmer the farther you move inland.
Below is the RPM forecast map for Sunday. The black features are ‘wind barbs’ and the one near Milwaukee indicates a general east wind. But with sunshine, Sunday is still looking ‘nice’.
Make sure to enjoy some of the events going on across southeast Wisconsin this weekend. From the beaches opening in Waukesha county, to the Mitchell Street Sun Fair, or the Scottish Fest at Hart Park. Take in what the summer season has to offer!
Have a great weekend!
