...waves building in excess of 4 feet over lake huron...
.a developing low pressure system over the plains today will support
increasing s-se winds across lake huron. the low will slowly rotate
into the western great lakes tonight into tuesday. persistent low
level warm air advection will increase over lake stability and thus
suppress peak winds from exceeding 25 knots. however...waves will
still likely reach around 4 feet across nearshore waters of northern
thumb region...and have issued small craft advisories. the surface
low will actually weaken as it lifts into the northern great lakes
on tuesday. a subsequent weakening in the gradient over lake huron
will lead to a diminishing trend in the wind and waves tuesday into
tuesday night. a secondary surface low is forecast to rapidly deepen
as it moves from the deep south tuesday night and in between the
central and eastern great lakes wednesday. this system will continue
to strengthen as it lifts northeast of the region wednesday night.
cold air advection in the wake of this system will pose the risk of
gale force winds over the lakes wednesday night into thursday
morning. enough uncertainty in the strength and track of this system
remains at this stage in the forecast to hold off on the issuance of
a gale watch.
