954 pm edt thu apr 2 2026

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...the central great lakes are positioned between
approaching low pressure from wisconsin and stalled high pressure
over quebec. a warm front associated with the low has been slow 
to lift into the southern waterways. the warm front precedes the 
track of the low late tonight as it heads toward the straits. 
some strong thunderstorms are still possible overnight. drier 
conditions expected friday, after the system's cold front clears 
through. however, unsettled weather returns friday night and 
saturday with a similarly tracking warm front and surface low.
