pressure over southeast saskatchewan will track across lake

night with an associated 29.6 inch trough surging across lake 
superior. as the low weakens to 29.4 inches while moving to southern 
hudson bay on sunday, 30.2 inch high pressure will build over the 
plains. this high will evolve into a north-south oriented 30.2 inch 
high pressure ridge that will drift to the middle and upper 
mississippi valley during monday night and to the western great
