...southerly gales on lake huron today...

.westerly and southwesterly winds will back to the south this morning 
and increase through the day as a surface ridge moves off to the 
eastern great lakes and a developing low pressure system lifts into 
northern lake michigan by this evening. the gradient will tighten 
through the afternoon as strong warm advection sweeps over, with 
just enough mixing and fetch over southern and central lake huron to 
allow for southerly gales by this afternoon and continuing into the 
evening. a gale warning remains in effect for much of the open 
waters, while a small craft advisory remains in effect for all of 
the lake huron nearshore waters. the low will bring likely snow 
across northern lake huron today that will eventually turn to rain 
tonight as warmer air moves in. winds taper off by tomorrow morning 
as the low weakens in the vicinity of the straits. broad troughing 
remains over the region friday into saturday, with light southerly 
winds friday afternoon eventually flipping to light northerly on 
saturday. a surge of arctic air will then move back into the region 
on sunday morning, leading to unsettled marine conditions once again.
