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.

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.

.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.
