... KEY MESSAGE 1...Extended period of fair weather.

Surface high pressure anchored over the eastern US this week will maintain fair weather with afternoon temperatures near or above normal.

Mid and high level clouds will increase this morning, as seen upstream over the central Great Lakes, but increasing sunshine will return this afternoon behind the upper level trough, with a clear sky and cool conditions tonight.
