Hottest 4th of July in six years!
A very warm weather pattern sets up shop in Wisconsin for the 4th of July. Expect the jet stream to head north and the hot, muggy air to continue to head north. Temperatures will make a run at 90 degrees, with dew points in the 70s. In the last 20 years, the area has only seen four other days in the 90s on the 4th. This will make it feel even hotter with heat index values nearing 100. This will be the warmest 4th in six years; in 2012, the record high still sits at 102 degrees.
With the summer-like conditions, instability will setup this afternoon, which could lead to spotty thunderstorms. There will not be great forcing, but with a lake breeze, storms could fire nearby. Some could contain gusty winds and small hail.
Models continue to push a wave and cold front in by tomorrow. This will give a chance of showers and thunderstorms, more organized compared to today. Even with the storms in the forecast, highs could still flirt with 90 degrees. The front will knock the temps down by Friday into the 70s.
