The blue skies Monday were spectacular. I hope you enjoyed the day. It will stay dry and mostly clear Monday night with lows in the lower 50s, not quite as cold as Sunday night. Light southwest winds will become southeast. The humidity will increase Tuesday with southerly winds ahead of a cold front in Minnesota. That front will bring at least a small chance of a few spotty showers and thunderstorms in the later afternoon and evening. There is some potential of a strong storm with hail and gusty winds, so be sure to monitor News 9 and waow.com for updates.
Otherwise it should be partly sunny Tuesday with highs around 79 degrees. Winds will be from the southeast early, then become southwest around 10 mph. Any showers in the area will end early Tuesday night. With partly cloudy skies, lows should dip down to the mid or upper 50s by Wednesday morning.
A large high pressure system will build in from Canada Wednesday and Thursday. It is bringing with it a batch of fairly cool and dry air. It will feel fall-like with highs in the low 70s (maybe upper 60s north), and lows in the 40s. In fact low temperatures will likely reach the 30s for a few nights in northern Wisconsin and other cold low-lying pockets in central Wisconsin. Hopefully there won’t be and light frost but it is not completely out of the question, especially in places like cranberry marshes. Otherwise it will be really nice and comfortable during the day with the bright sunshine expected. It will be a bit breezy Wednesday then lighter winds will be the rule Thursday and Friday.
Temperatures will start a slow climb on Friday with highs returning to the mid 70s. We could hit the upper 70s Saturday, around 80 Sunday and the low 80s next Monday. The nights will get warmer as well as more humid air starts to work in.
At this point the pattern looks somewhat active from Saturday through Monday with a few rounds of scattered showers and thunderstorms possible. We’ll fine tune that as we draw closer and the weather systems get better defined in space and time.
Have a good evening! Meteorologist Tony Schumacher, 2:50 p.m., 19-August 2019
