830 am cst mon mar 2 2026
for waters beyond five nautical miles of shore on lake michigan.
waves are provided as a range of significant wave heights, which
is the average of the highest 1/3 of the wave, along with the
average height of the highest 10% of the waves which will
occasionally be encountered.
.synopsis...
low pressure around 29.5 inches will move east into hudson bay
today, with high pressure around 30.6 inches moving east through
the northeastern conus. this will drive breezy south to southeast
winds across lake michigan today, particularly over the northern
third of the lake where gusts to 30 knots are possible. winds will
subside tonight into tuesday as both pressure systems depart
eastward, with light and variable winds tuesday afternoon through
tuesday night.
light east to northeast winds develop into wednesday as weak low
pressure around 29.9 inches develops over the central great
plains, tracking northeastward through the middle mississippi
river valley. the low will approach and ultimately pass near or
just south of the southern portions of the lake wednesday night
into thursday. east to northeast winds will linger. periods of
rain will accompany the low wednesday into thursday, with a few
thunderstorms possible over southern lake michigan wednesday
afternoon and evening.
another low pressure system around 29.5 inches will form in the
central great plains thursday night, and is forecast to progress
toward the upper mississippi river valley during the day on
friday. the approach of the low will bring increasing southerly
winds to the open waters on friday, along with widespread areas of
rain and embedded thunderstorms.
the low will move northeast across the region and into ontario
friday night through saturday, dragging a cold front across lake
michigan in the process. additional rain is expected during the
frontal passage. winds will veer southwest to west as the front
passes.

.synopsis...
a 30.6 high currently centered over lake ontario continues to shift
east today as a 29.7 inch low over northern manitoba moves east over
hudson bay, deepening to 29.6 inches. the low drags a weak trough of
30.2 inches over lake superior tonight before weak ridging builds
over the lake on tuesday as another, more compact high of 30.4
inches moves to james bay. another large area of high pressure will
move into central and eastern canada by thursday morning. the strong
high will help keep a 29.7 inch low moving up from the southern
plains to our south as it weakens to 29.9 inches by the time it
reaches the lower great lakes wednesday night, dissipating
thereafter.
