407 AM EDT Fri Aug 18 2017

...Breezy and Cooler Today with Clouds...

.DISCUSSION...
Breezy and cool today thanks to a low pressure system centered
near Sault Ste Marie. Another fast moving disturbance may bring
a few showers tonight into early Saturday, mainly south of
Interstate 96. High pressure will provide mostly clear skies and
warm temperatures Saturday and Sunday, and probably into most of
Monday as well. Our next good chance of showers and storms is
Monday night and Tuesday with a strong cold front.
