Great Lakes Ice Outlook
National Weather Service Cleveland Ohio
552 PM EST Fri Feb 16 2018

Active watches...warnings...and advisories on the Great Lakes can

5 Day Ice Discussion...

High pressure will shift east of the Great Lakes tonight. This will allow
low pressure to swing cross the region on Saturday. On Sunday all but the
upper Great Lakes will see a warming trend to begin. Wind speeds will
generally be 10 to 25 knots so there will be movement of the ice.

Temperatures will remain near seasonal averages across the upper lakes
but elsewhere well above average temperatures are expected to develop,
especially for the beginning of next week. Expect the ice to slowly
deteriorate Sunday into next week.
