will very slowly meander eastward, with a 29.4 inch trough slowly
scooting to the south across the Ohio Valley tomorrow into the
start of the weekend. The Upper Great Lakes will be wedged in
between these systems, with pressure lingering around 29.8 inches
into early next week. Starting Monday, pressures will begin to
rise locally as a 30.4 inch ridge builds in across the Plains.
