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...

elevated waves and cold temperatures will support heavy freezing 
spray across the open waters through this evening. a heavy 
freezing spray warning is in effect until 6 pm cst for the
northern third, and until 9 pm cst for the southern two thirds.
patchy moderate to heavy freezing spray is possible wednesday
morning through wednesday night for the southern half of the open

northwesterly winds will slowly diminish this evening and tonight 
as low pressure around 29.6 inches in eastern ontario exits into 
quebec and high pressure around 30.5 inches builds through the
northern plains. high pressure will linger across the northern
plains through the week, keeping winds northwesterly. high
pressure will strengthen into friday as weak low pressure
progresses through the middle mississippi valley, turning winds
briefly northerly to even northeasterly. winds shift back to
north-northwesterly and increase friday night. moderate to heavy 
freezing spray will likely develop once again as northwesterly
winds continue through saturday.
