CHICAGO (CBS) — It will be quiet overnight as high pressure remains in control, with a low of 68.
That ridge moves away in the morning. We expect shower and thunderstorms to form along the approaching warm front.
This first round could arrive during the morning hours. Once we get into the “warm sector” of the system – the hot and humid area between the warm and cold front – we could see another chance of scattered storm activity during the early afternoon.
The main severe threat comes late day into sunset through midnight as the cold front interacts with the hot and humid air mass that will be in place.
The Storm Prediction Center has the higher risk of severe weather for parts of Wisconsin and lower Michigan. We have a “slight” risk, meaning a 2 on a scale of 1-5.
Possible hazards include damaging winds and hail. If the storms train in place, localized flooding could be an issue.
An isolated tornado is also possible.
The high for Friday is 90.
