National Weather Service Detroit/Pontiac MI

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...Weak high pressure will build in behind a stalled
front over the Ohio Valley and hold over northern Ontario through
Wednesday. Low pressure will then organize over the central
plains and deepen to 29.50 inches as it tracks into the northern
Great Lakes by early Friday morning. A warm front will lift north
into the region during this time frame with a trailing cold front
pushing back south through the area on Friday in the wake of the
passing low pressure system.
