Scattered showers and thunderstorms are expected today, but not everyone will see rain. Seasonal temperatures continue.
Atwater Buoy located about a little over a mile off northern Milwaukee County in the near shore waters of Lake Michigan is located over about 65 feet of water. Besides measuring surface conditions, the buoy also measures a temperature profile of the sub-surface water. Over the past 5 days, the sub-surface temperature has remained mostly in the upper 50s to middle 70s. At 62 feet, which is close to the lake bottom, the temperature of the water remains in the lower 40s. As of Tuesday afternoon, the lake surface water temperature was in the warm mid-70s. Once winds begin to increase off-shore, some of the cooler sub-surface water may be drawn to the lake surface. The Atwater Buoy data is available online at http://glbuoys.glos.us/45013/.
