waves are provided as a range of significant wave heights, which
is the average of the highest 1/3 of the wave, along with the
average height of the highest 10% of the waves which will

.synopsis...

low pressure will quickly strengthen to around 28.8 inches as it

force winds then anticipated later tonight into monday afternoon.

winds will back off slightly from storm force to gales late 
monday afternoon and then continue into early tuesday. a storm 
warning has been issued for all of lake michigan tonight into 
early tuesday. after the period of storm force winds and gales, 
breezy northwest flow below gale force will last late into the 
week.

will spread across the great plains as the low lifts into quebec on 
monday. a 29.7 inch trough dives southeast into the upper great
