.synopsis... 

tonight, weak ridging of 30.1 inches builds in over lake superior 
thanks to a 30.4 inch high over the western shores of hudson bay. 
this parent high shifts southward over lake superior on thursday, 
causing pressure to increase to 30.3 inches. on friday, the high 
weakens to around 30.1 inches as it continues its southerly 
propagation. following this, a second ridge pushing in from hudson 
bay brings 30.1 inch ridging back over lake superior late on friday, 
with pressure increasing once again to 30.3 inches by saturday 
midday as the parent high over hudson bay propogates south. high 
pressure over lake superior remains until sunday evening and 
decreases to 30.1 inches sunday night as the parent high moves 
toward the lower great lakes.
