average height of the highest 10% of the waves which will

.synopsis...

high pressure of 30.7 inches will remain over the western great
lakes through today, with a convergent zone bringing lake effect 
snow potential to the southern half of lake michigan from this 
afternoon into sunday. high pressure slides eastward tonight as
low pressure of 29.6 inches develops in the lower mississippi
valley. expect the convergent zone to strengthen tonight, with 
lake effect snow continuing. northeasterly winds are expected east
of the band, with northerly winds west of the band. the band will
transition westward toward wisconsin sunday morning, then back 
eastward sunday afternoon and evening. all winds shift to 
northwesterly sunday evening as low pressure moves into the mid- 
atlantic. high pressure centered over the southern plains then 
dominates the pattern through midweek, leading to generally 
westerly winds. a few clipper systems are possible early to 
midweek, bringing periods of 25 to 30 kt gusts. gusty winds 
combined with frigid temperatures will lead to moderate / heavy 
freezing spray sunday night through tuesday. a heavy freezing 
spray warning is in effect.
