occasionally be encountered.

.SYNOPSIS...

A broad area of low pressure of 29.8 inches over West Virginia
will move to near New York tonight, while high pressure of 30.7
inches begins to move south from Canada into the northern Great

east to northeast, and then eventually north and northwest late
tonight into Monday morning.

That area of high pressure will slide across the Great Lakes
Monday and Tuesday, bringing generally quiet weather to the area.
Low pressure of 29.8 inches will then cross Lake Michigan on
Wednesday and the eastern Great Lakes Wednesday night. High
pressure of 30.3 inches will return to the Great Lakes later in
the week. No gale force winds are expected through Thursday.
