Wet weather will diminish across the East Coast on Sunday as a low pressure system in eastern Canada lifts northeastward and away from the region. Flow around the system will continue producing lake effect rain showers across the southeastern shores of the Great Lakes, but shower activity will be light and widespread.

A cold front associated with the system will lift northeastward by mid-day, allowing for a few more showers and thunderstorms to develop over the far Northeast early in the day.As the system moves further away, it will continue pushing cool air in from central Canada. This will allow for chilly Fall weather to spread from the Upper Midwest and into the Ohio River Valley and Northeast.

High temperatures will remain in the 60s for these areas, while overnight lows will dip into the upper 20s for some of the Northern Tier states. Frost and freeze advisories will remain in effect for parts of the Upper Midwest and Great Lakes regions.
