It's feeling like fall across much of the country, as storms move across Central US

Frost advisories have been issued for some parts of the Northeast.

It's finally feeling like fall across much of the Northeast, with temperatures Saturday morning the 40s and 30s.

Freeze warnings and frost advisories have been issued for parts of the Northeast as well as parts of Michigan.

Some thunderstorms and rain are already moving through the Dakotas, Minnesota, and Iowa Saturday morning.

By tonight this system will move eastward. Along the cold front, there could be an isolated strong storm in parts of Oklahoma, Arkansas and Missouri.

On Sunday and Sunday night, storms will track south and eastward, with some heavy rain falling in parts of the South and into the Appalachians.

Three to four inches of rain is possible across parts of the Tennessee Valley and western Appalachians, where some localized flooding will be possible.

Behind this system, the dry air from Canada continues to push into the Lower 48 as we get deeper into fall. However the dry air, combined with some localized gusty winds, is raising concerns for fires in parts of Colorado and California this weekend.

Red flag warnings have been issued for parts of Northern California and some of the Rockies west of Denver. Relative humidity could be as low as 10 percent, with wind gusts up to 45 mph in spots.
