The next seven days will be much cooler and seasonal, and drier air will filter into the area with plenty of sunshine.

Interesting Storm Fact:
A measurable seiche took place on Lake Michigan early Thursday morning. Lake levels registered a 1.5 to 2.5-foot rise in water levels due to the storms.
What's a seiche? It is a sudden oscillation of water levels due to pressure change (usually caused by a passing storm). Think bathtub water swooshing from side to side.
On June 26, 1954, there was a deadly 10- foot seiche that killed 8 fishermen as they were swept from piers and breakwaters at Montrose Beach and North Avenue Beach.
