The frost advisories for much of Western New York have expired, but not before temperatures dipped just below freezing overnight in outlying inland areas, the National Weather Service said today.

Frost was reported throughout the area, once you got at least five or six miles inland from local waterways, with the coldest temperatures reported in the Southern Tier valleys.

Volunteer spotters reported overnight lows of 29 degrees in Jamestown, 31 in Wales and Warsaw and 32 in Olean and Pavilion, meteorologist Jon Hitchcock said. The overnight low at the National Weather Service office in Cheektowaga was 36.

The area will experience a quick warmup today and tonight, with an expected overnight low of 49 in the city and low to mid 40s farther inland.

That won’t last for long, of course, with fall already here. The National Weather Service forecast calls for another cool-down on Friday.

“I think it will be colder than last night,” Hitchcock said.
