.MARINE...
Broad high pressure settles across the region today offering light
and variable winds with abundant sunshine early giving way to high
clouds late. Dry weather holds through Monday with milder southerly
flow commencing as low pressure develops over the Midwest. This
system will track across the northern Lakes late Monday into
Tuesday, sending a warm front through Tuesday morning before the
cold front follows later in the day. The warm air arriving over the
cool lakes will result in strong atmospheric stability and limit
wind magnitude to a degree, but periods of gusty 25+ kt wind will be
likely, especially in the nearshore areas. A 40 percent chance
exists for a brief period of gusts to gales over Saginaw Bay.
Scattered thunderstorms are expected to accompany the system's cold
front on Tuesday with potential for some strong to severe storms in
the south. A period of gusty northwest wind follows the system
Tuesday night before high pressure builds back in on Wednesday.
