...gale force winds may develop over lake huron friday...
.gusty west winds will continue to subside this evening as low
pressure over northern quebec continues to lift northeast and a
ridge of high pressure builds into the area. the ridge will keep
winds fairly light and wave heights fairly low through thursday
evening. a low pressure system and arctic cold front will then drop
southeast through the central great lakes very late thursday night
through friday. northerly winds will become strong behind the front
friday and friday night...with gusts likely reaching gale force over
much of lake huron. a gale watch may also be needed for lake st
clair and western lake erie. the strong persistent northerly winds
will allow wave heights to build as high as 14 feet over the
southern portion of lake huron. winds will gradually diminish on
saturday as the low moves east and high pressure builds into the
area...however large waves will persist over the southern portion of
lake huron through saturday.
