open lake forecast for lake huron
national weather service detroit/pontiac mi
354 am edt tue apr 7 2020

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...high pressure will continue to wash out towards the
east overnight followed by low pressure arriving on tuesday. this
low will bring wet weather and barometric pressure falls to
around 29.50 inches. high pressure, 29.80 inches, briefly expands
from the eastern plains on wednesday before a cold front tied to
a low, 29.30 inches, moves through wednesday night bringing in
stronger winds and waves.
