Open Lake Forecast for Lake Superior
National Weather Service Marquette MI
411 AM EST Wed Nov 13 2019

For waters beyond 5 nautical miles of shore on Lake Superior.

Waves are the significant wave height - the average of the
highest 1/3 of the wave spectrum. Occasional wave height is the
average of the highest 1/10 of the wave spectrum.

.SYNOPSIS...A 30.4 inch high currently centered over northern
Ontario will shift eastward today. This will leave the Upper 
Great Lakes sandwiched between that high over the Mid-Atlantic
tomorrow, and another 30.2 inch high centered over the Northern 
Plains. In between, a 29.6 inch low will spill its axis down from
the Hudson Bay. Late Thursday, the aforementioned Plains high will
build to 30.4 inches into the Southern and Central Plains, with
the Hudson Bay low deepening to 29.4 inches. On Friday, these
features will shift eastward, with a 30.5 inch high moving into
Lake Superior later in the day from Manitoba. This high will build
to 30.7 inches over southern Ontario on Saturday. An ill-defined
pattern emerges for the latter half of the weekend, until a 29.6
inch low slides across Manitoba toward the Upper Great Lakes on
Monday.
