.synopsis...

low pressure around 29.2 inches over east central michigan will very 
slowly track east to lake huron by this evening. west to northwest 
gales will persist across the southern two-thirds of the lake 
through this evening. thus the gale warning will remain in effect. 

the northwest winds will subside tonight as the low pressure weakens 
over lake huron. northwest to north winds will continue across the 
lake into early next week as a polar high pressure around 30.4 
inches builds south into the upper great lakes. as the high 
builds in the pressure gradient will tighten sunday night into 
monday. winds will approach gales force during this time. light 
and variable winds are then expected monday night into tuesday as 
the high moves overhead.
