National Weather Service Milwaukee/Sullivan WI
304 AM CDT Thu Jun 20 2024

Waves are provided as a range of significant wave heights, which

average height of the highest 10% of the waves which will
occasionally be encountered.

.SYNOPSIS...

Patchy dense fog is possible across the southern half
early this morning. Patchy dense fog is possible once again
overnight tonight into early Friday morning.

Light northeast winds will continue across the lake tonight into
Thursday night as high pressure around 30.4 inches sits over Lake
Superior. Low pressure of 29.6 inches developing in the central
High Plains Friday will then allow a stationary front to develop
across the open waters, producing periods of thunderstorms. Low
pressure will lift into southern Minnesota on Saturday, leading to
gusty southerly winds and continued periods of thunderstorms
across the lake. Winds shift southwesterly into Saturday night,
and westerly on Sunday as low pressure departs to the east.
