***Watch WISN 12 News for the latest weather information!***
Thank you for stopping by the Weather Watch 12 blog! Much warmer weather is in store for Sunday, that’s the good news. The bad news, a chance of strong to severe storms will accompany the warmer weather. In this blog entry we will look at the timing for Sunday’s potential storms, and also look at the locations that stand the best chance of seeing severe weather.
Let’s start with temperatures. For the past several days, and most of this spring, you’ve heard ‘cooler by the lake’ quite a bit. With winds more south to eventually southwest on Sunday, most lakeshore locations should warm into the 70s, with some inland areas touching 80.
Below is the RPM model’s forecast temperatures at 3pm. Time to fashion the shorts and t-shirts!
As the temperatures climb, so will the threat for severe weather. The give and take this time of year is often warmer weather and a storm system, can equal strong to severe storms. The Storm Prediction Center has included all of southern Wisconsin in it’s outlook as having a ‘slight risk’ for severe storms on Sunday.
The main threat for southeast Wisconsin with any storms would be large hail, damaging winds, and heavy rains within thunderstorms. I think closer to the center of low pressure over west-central Wisconsin isolated tornado(s) may be possible. Something we’ll watch closely as Sunday evolves.
So when are the storms possible in southeast Wisconsin? The timing for storms looks to be late in the day. Anywhere from late afternoon into the evening hours. I think the most likely timing is after 6pm and that will likely continue through about midnight or 1am in areas.
Below is the RPM surface forecast at 9pm Sunday. The red indicates what could be strong to severe storms. Please keep in mind this is just one model’s forecast for Sunday. However, I do believe that evening is the most likely time for storms to reach our part of the state.
Finally, on Saturday morning I represented WISN 12 and helped kick-off the 1st ever Bay View Fox Run 5K to benefit the Healing Center. It was a great morning, and it stayed dry for the runners and walkers. The rain came in about when the event was wrapping up after 11am. The turnout was fantastic, the picture below shows the long line at the registration tent around 9am. I want to thank the organizers for inviting me to kick-off the run/walk!
