Plenty of high clouds today but rain chances are very low and
confined to far southern areas. Fair and slightly cooler than
normal through Saturday then rain chances increase on Sunday in
advance of a vigorous upper low moving across the Great Lakes
region.

We can expect a diurnal enhancement of showers and a slight
chance of thunder in the afternoon and evening each day from
Sunday through Tuesday. The low moves out late Tuesday with fair
weather returning for Wednesday.
