5 Day Ice Discussion...

Winds will become light and variable across the Central Lakes
overnight as high pressure moves through.  Winds will turn to the N
to NW at 10 to 20 knots Thursday night and continue into Saturday,
as another cold front pushes across the Lakes.  Some shifting of the
ice is possible especially in areas exposed to the north wind and
tracks may not hold.  Winds will diminish Saturday night as high
pressure builds in.  High pressure will be the dominant feature
across the lakes for the remainder of the period. Large area of high
pressure will be centered over the Northern Lakes Saturday.  The
high will track slowly SE and move off the SE Coast Tuesday.

Ice deterioration will continue through the entire forecast period.
Temperatures will be normal to a little below normal through the
weekend, but then temperatures will warm to above normal Monday and
much above normal Tuesday.
