OMAHA, Neb. (AP) — After days of scorching heat and strong winds, a shift in the weather is helping firefighters battle wildfires burning in north-central Nebraska along the scenic Niobrara River.

Nebraska Emergency Management Agency spokesman Mike Wight says an overnight cold front saw temperatures drop, humidity increase and winds die down in the area on Wednesday.

Wight says the biggest help to firefighters might be a shift in the wind, which had been coming from the south and pushing flames into trees and other growth along stream beds. With the wind now coming from the northwest, it’s helping keep the fire out of those channels.

Wight says firefighters will learn early Thursday whether they were able to keep the fires, which have burned about 113 square miles altogether.
