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

.synopsis...

high pressure near 30.5 inches will drift southeast into the 
northeastern united states through this afternoon, maintaining 
south-southeasterly winds over lake michigan. low pressure near 
29.5 inches will develop over eastern colorado this evening, 
progressing into the upper mississippi river valley by early 
tuesday morning. winds will steadily become gusty ahead of the 
low, approaching or exceeding gale force over at least the 
central third of the lake tuesday afternoon and evening. 
anticipate that headlines will become necessary in later 
forecasts. rain will accompany the approaching/passing low monday 
through tuesday night, with a few thunderstorms possibly mixing 
in. severe weather is not expected at this time. 

winds will remain breezy, though likely below gale levels wednesday 
and wednesday night as 30.1 inch high pressure slowly builds into
the canadian great plains. said high will move into the western 
great lakes through the second half of next week, allowing for 
westerly and eventually northerly winds by next weekend.
