.SYNOPSIS...

High pressure around 30.6 inches over northwest Illinois will
slowly expand eastward to northern Ohio for the weekend.
Meanwhile, low pressure of 29.8 inches will move southeast along
the southern coast of Hudson Bay. This will keep a steady west to

pressure of 29.7 inches begins to form over the southern Rocky
