Crisp fall weekend, warm-up coming this week but no rain

Low pressure over southeastern Canada has drawn much cooler and drier air into Ohio this weekend, ending a bout of summertime heat and humidity.

After a chilly morning in the upper 30s and low 40s, sunshine will prevail, with a northwest wind. The skies will be mostly sunny, along with some high, thin clouds. Afternoon temperatures will barely rise above 70 degrees, followed by another cool night in the 40s.

High pressure building in from the west will provide lots of sunshine and another fall-like day.
A warm-up will develop through the week, with lots of sunshine, as summerlike weather returns in a southerly flow behind high pressure that will shift eastward. High temperatures will flirt with 90 degrees Wednesday and Thursday.

Rain chances are nil until possibly late next weekend, when a surge of tropical moisture lifts northward to the Ohio River. Increasing clouds will lower temperatures back to the mid-80s.
