.MARINE...
Stalled frontal boundary maintains shower chances over the southern
Great Lakes through Sunday. Expansion of strong high pressure over
northern Ontario finally shunts this front deeper into the Ohio
Valley. Locally, the central Great Lakes reside on the edge of this
high resulting in a respectable gradient across the region
throughout the entirety of the early week period. This supports
moderate northeasterly through Tuesday before shifting more easterly
by Wednesday (while maintaining strength). While gales currently
look unlikely, onshore flow warrants long duration Small Craft
Advisories for all nearshore waters.
