Chilly Fall temperatures spread into the East as a low pressure system in Canada pushed a cold front eastward throughout the day.

The front kicked up scattered showers and thunderstorms as it stretched from the Ohio River Valley, through the Midwest, and into Arkansas. The tail end of this system had a slight chance of severe weather development, but severe storms have not yet been reported.

Rainfall totals ranged around 1 inches across most of the frontal boundary, while wind gusts ranged from 20 to 30 mph in some areas. Temperatures dropped by 10 to 20 degrees as this front passed, with highs in the Midwest remaining in the 40s and 50s, while the Southeast and Mid-Atlantic states saw highs in the 70s and 80s.

Behind this system, a cold trough of low pressure slid southeastward from the Rockies, into the Central Plains. This system triggered a few scattered snow showers as it moved eastward throughout the day. Snowfall accumulation ranged from 1 to 3 inches in parts of Wyoming, Colorado, and into western Nebraska.

In the South, the tail end of a cold front lingered over Florida. This system produced a few more showers and thunderstorms, but severe thunderstorms and heavy rains were not anticipated.
