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...a secondary weak low pressure system, 20.50 inches,
will track along a stationary front which is draped across lake

cold front and reinforce the arctic airmass bringing borderline 
gales across lake huron late this afternoon and early evening.

.synopsis...

northwesterly winds prevail across the lake today as strong low
pressure around 28.2 inches meanders back into the hudson bay 
region. extending off of this low is a secondary cold front that 
is expected to slide down across the lake through the day with 
increasing northwesterly gusts behind it into this evening. 
cannot rule out seeing a few gales across the far northern 
portions of lake michigan this evening, but this window looks 
brief. thus have held off on any gale headlines at this time. 
however, with the colder airmass and gusty winds behind the cold 
front, moderate freezing spray will be a concern overnight into 
new year's day. winds will then slowly lessen through thursday as
high pressure around 30.3 inches builds down across the upper 
midwest thursday through the weekend.
