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...

stronger northwesterly winds will continue overnight, as strong 
low pressure deepens to around 28.6 inches off the mid-atlantic 
coast, and strong high pressure moving into ontario builds to 
around 31.1 inches. gales are expected across the southern two- 
thirds of the open waters of lake michigan, and a gale warning 
remains in effect into midday monday. with the brisk conditions, 
moderate freezing spray is expected, with brief periods of heavy 
freezing spray possible in the central to northern third of the 
lake. 

weakening high pressure around 30.6 inches will continue to push 
eastward through the day monday, with winds gradually easing 
overnight. southerly winds look to develop across the lake
tuesday, as low pressure deepening to around 29.3 inches shifts
from the dakotas to across lake superior and northern lake 
michigan tuesday afternoon and evening. 

winds will shift more west northwest behind the low and 
associated cold front. winds gusting up to around 30 knots are 
expected during this time, and while potential is lower, still 
cannot rule out a few gale force gusts later tuesday into early 
wednesday morning.

coast, and strong high pressure moving into ontario builds to 
around 31.1 inches. gales are expected across the southern two- 
thirds of the open waters of lake michigan, and a gale warning 
remains in effect into midday monday. with the brisk conditions, 
moderate freezing spray is expected, with brief periods of heavy 
freezing spray possible in the central to northern third of the 
lake. 

weakening high pressure around 30.6 inches will continue to push 
eastward through the day monday, with winds gradually easing 
overnight. southerly winds look to develop across the lake
tuesday, as low pressure deepening to around 29.3 inches shifts
from the dakotas to across lake superior and northern lake 
michigan tuesday afternoon and evening. 

winds will shift more west northwest behind the low and 
associated cold front. winds gusting up to around 30 knots are 
expected during this time, and while potential is lower, still 
cannot rule out a few gale force gusts later tuesday into early 
wednesday morning.
