Lake Superior will be whipped into a frenzy late tonight and Wednesday, with strong northeast winds expected to build waves up to 25-feet in some open areas of the big lake.
The National Weather Service in Duluth has issued a gale warning and small craft advisory for the western portions of the lake with sustained winds of 40-mph expected Wednesday and gusts to 50-mph. Waves are expected to hit 11 feet at this end of the lake, with higher waves along the South Shore.
The Marquette office of the Weather Service is calling for waves in the more open parts of Lake Superior to reach 17-to-25-feet high.
A strong low-pressure system is tracking northeast out of Iowa toward Michigan tonight and Wednesday. Along with strong winds the system will bring heavy rain to much of Wisconsin, including 1-to-2 inches in northern Wisconsin. A flood watch is posted for many northern counties from tonight to Wednesday afternoon, including Bayfield, Ashland, Iron, Washburn, Sawyer and Price.

With heavy rain falling on already swollen streams from storms last week, the Weather Service says some flooding is expected to occur in low-lying areas.
The flood watch does not include the Twin Ports, but rain is likely across most of the region tonight and Wednesday.
After July-like high temperatures for most of September so far, much colder air will funnel into the region starting tonight, with highs only in the 40s Wednesday and Thursday, and lows in the 30’s into the weekend. Areas form the Iron Range north could see frost on Friday and Saturday morning.
Temperatures are expected to rebound to normal seasonal levels by Monday.
