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

spray warning is in effect until 6 pm cst tuesday.

a 29.6 inch trough of low pressure will cross lake superior
tonight. gusty southwest winds this evening will veer to the west

period of gale force gusts up to 35 kt is expected between 9 pm

this event.

and night as 30.4 inch high pressure builds into the northern 
great plains. winds will gradually taper wednesday through 
thursday as said area of high pressure moves into the upper
