There was quite a line of thunderstorms moving toward northwest Wisconsin Tuesday morning but it gradually fell apart the further east and south it got into the state. As such we ended up mostly dry with patches of clouds. A cold front is moving through Tuesday evening, but it looks like it may pass uneventful. Otherwise it should be partly cloudy with lows into the upper to mid 50s. Winds will become northwest around 10 mph.
Wednesday should be partly cloudy, less humid, and a bit breezy as high pressure approaches from the northwest. The temperatures won’t warm up too much, just to around 73, which is about 5 degrees below normal. Winds will be from the northwest at 10-15 mph. The big high pressure system will sit over our region all the way through Saturday. Thus you can expect quite a bit of sunshine over the period and very quiet conditions. It will stay cool for a few more days with highs just around 70 on Thursday, low 70s Friday, and perhaps inching up to the mid 70s Saturday. The low temperatures should be in the 40s generally. However the Northwoods will likely drop into the 30s Wednesday night and Thursday night, as well as low-lying areas in the rest of the region such as cranberry marshes. It will certainly be a taste of early autumn.
Milder and more humid air will flow in later this weekend. That could lead to a few showers and thunderstorms by late Sunday. There is potential of a more substantial soaking of rain Monday. That should be followed by dry weather next Tuesday. High temperatures should hit the upper 70s Sunday and Monday and perhaps dip a few degrees Tuesday. Lows should be in the 50s although possibly the low 60s Sunday night as the warmest.
Have a good evening! Meteorologist Tony Schumacher, 8:15 p.m., 20-August 2019
