slightly deepening 29.7 inch low will slowly make its way from the 
central great lakes to western quebec today and sunday, while

will wobble across western quebec through monday, then eject 
northeastward across labrador on tuesday while a 30.1 inch high 
builds eastward across the ohio valley. this surface high will drift 
across the southern mid-atlantic states wednesday, and to the east 
coast by wednesday night.
