.synopsis...

a 29.5 inch low over eastern upper michigan slowly meanders just 
north of gregorian bay on saturday, weakening to 29.8 inches by 
saturday evening when it reaches quebec. meanwhile, a 30.5 inch high 
sets up over the plains. while low lifts northeast through quebec 
saturday night, the high settles toward the southeast u.s., briefly

replaced by a 29.8 inch clipper low on sunday. the low deepens to 
29.6 inches over far eastern lake superior sunday night, then moves 
to quebec on monday while another high pressure of 30.5 inches drops
