Waves are the significant wave height - the average of the
highest 1/3 of the wave spectrum. Occasional wave height is the

.SYNOPSIS...A 30.0 inch low pressure trough extending north to south 
across Minnesota will sweep across Lake Superior today. In its wake, 
a 30.4 inch high pressure ridge will build southeast toward the 
Upper Mississippi Valley tonight. This ridge will then reorient 
across southern Manitoba and northern Ontario on Monday as 29.5 inch 
low pressure develops over eastern Kansas and Missouri. As the low 
moves off the Mid-Atlantic Coast on Tuesday, a high pressure center 
of 30.5 inches will settle over southern Manitoba. This high will 
then build to 30.7 inches as it drifts to northern Ontario on 
Wednesday and Thursday. An associated southward extending ridge 
will cross Lake Superior on Thursday.
