.synopsis...

high pressure continues to work across the region will bring the 
lighter, west-northwesterly winds this evening, but will begin to
see winds pick back to the south and easterly overnight into 
saturday as low pressure around 29.8 inches tracks across ks 
saturday morning to the south tip of lake michigan saturday night.

winds and expecting to reach gale force gusts as the low pressure 
approaches later saturday into saturday evening and a gale warning
is issued for the southern third of the lake, while small craft 
conditions for southern wi near shores. winds will weaken below 
gale as the low pressure passes the southern tip of lake michigan 
overnight saturday, but small craft conditions for the nearshores 
continue as we see this low deepen to around 29.7 inches as it 
lifts into lake huron by mid-sunday. stronger northwesterly winds 
will develop and expect to reach gale force once again across the 
open waters with the colder air mass moving into the region. thus 
a gale watch is in effect for sunday. high pressure will then 
build in later sunday into the start of next week with light 
winds.
