“Hot and Humid” to Subside, Says National Weather Service

Today will be the last day of the hot and humid conditions, at least
for this week.   A cold front stretched across the Central Great
Lakes will push SE across the forecast area this evening. 

Front expected to push SE of the forecast area toward midnight
local, taking the convection with it, and ushering in cooler and
less humid conditions.   Canadian high pressure will push into the
Central Great Lakes tomorrow.   High temps tomorrow only in the mid
to upper 70s with dew points in the 50s.

High pressure will be in control of the region Thursday night
through Friday afternoon. We will then have increasing southwesterly
flow on Saturday as the next weakening cold front moves into the
central Great Lakes. The increase in low level moisture will
contribute to the scattered thunderstorm chances. These
thunderstorms should occur around maximum heating Saturday afternoon
and linger into the evening.
