for waters beyond five nautical miles off shore on lake huron

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...wind will strengthen out of the east-southeast today 
as a low pressure system, 29.60 inches, tracks east across the 
southern great lakes. a deeper low moves into the region sunday 
night, bringing increasing potential for northwest gales on monday
as arctic air filters back in.

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

.synopsis...

low pressure of 29.7 inches over the upper mississippi valley to 
western lake superior will continue to progress eastward today,
bringing modest southeasterly winds to lake michigan this morning,
transitioning to light and variable this afternoon before a cold
front shifts winds to northwesterly this evening into tonight.
high pressure around 29.9 inches builds in briefly tonight into
saturday, with light and variable winds again.

modest southeast winds will then return by midday saturday and
continue through sunday morning as low pressure develops over the
central plains. low pressure deepens to 29.5 inches saturday
evening and crosses southern lake michigan, bringing gusty
northwesterly winds up to gale force. the low will continue to 
deepen throughout monday as it moves eastward, reaching 29.0 
inches in southern quebec monday night. confidence is high in gale
force winds through monday night. much colder air will also bring
moderate freezing spray throughout this time frame.

400 am est fri dec 26 2025

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...

low pressure of 29.6 inches moves east along the southern end of the 
great lakes basin today while extending a 29.8 inch trough north 
over the upper great lakes. 30.1 inch ridging builds across the 
region saturday before another low of 29.6 inches then lifts over 
lower michigan sunday while extending a 29.8 inch trough northward 
across the lake. by monday, a strong high pressure of at least 30.6 
inches will reside over the great plains as the low deepens to 29.0 
inches over quebec, yielding a tight pressure gradient across the 
great lakes.
