Waves are the significant wave height - the average of the highest
1/3 of the wave spectrum. Occasional wave height is the average of
the highest 1/10 of the wave spectrum.
.SYNOPSIS...Surface low pressure exits into James Bay while its cold front
stalls over the southern Great Lakes. Briefly dry conditions give
way to additional opportunities for showers and perhaps a couple
thunderstorms tonight and Friday as an upper level disturbance from
the High Plains moves into the Great Lakes. Some light snowfall is
possible for the north/central Huron basin. High pressure then
builds out of the Upper Midwest to start the weekend with drier and
calmer conditions. Active weather will be possible again Sunday
through Tuesday due to several passing disturbances.
