slightly over lake superior, decreasing to 30.1 inches along the

mid-atlantic at 30.5 inches into wednesday as pressure continues to 
fall slowly over lake superior, reaching 29.9 inches in the west and 
30.2 inches in the east by wednesday afternoon. pressure over lake 
superior then falls abruptly through thursday as a colorado low 
approaches northern minnesota late wednesday and tracks directly 
over lake superior at 29.8 inches on thursday. the low transits 
quickly northeast, and pressure begins to increase over lake supeior 
by early friday.

.synopsis...

high pressure extending from ontario into the mississippi river 
valley builds from 30.3 inches to 30.4 inches into tomorrow as it 
slowly drifts eastward, having already become centered over 
illinois. this sends ridging at 30.3 inches over lake superior 
through tonight. ridging continues to build to 30.6 inches, shifting 
southeast and reaching west virginia by late tuesday. pressure falls 
slightly over lake superior, decreasing to 30.1 inches along the 
northwestern shoreline of lake superior, and remaining at 30.3 
inches near whitefish bay late tomorrow. the high lingers over the 
mid-atlantic at 30.5 inches into wednesday as pressure continues to 
fall slowly over lake superior, reaching 29.9 inches in the west and 
30.2 inches in the east by wednesday afternoon. pressure over lake 
superior then falls abruptly through thursday as a colorado low 
approaches northern minnesota late wednesday and tracks directly 
over lake superior at 29.8 inches on thursday. the low transits 
quickly northeast, and pressure begins to increase over lake supeior 
by early friday.
