NOON UPDATE
A flash flood warning has been issued for parts of Logan, Polk, Scott, Yell and Montgomery counties until 1 p.m., according to the National Weather Service.
Up to three inches of rain had already fallen in some places, and excessive runoff will cause small creeks, streams, roads and other low-lying places to flood, the agency said. Areas expected to experience flooding include Mount Magazine, Havana, Union Hill and Grayson.
Flood warnings have also been issued along several rivers in Arkansas, according to the weather service.
A flood warning issued for the White River includes parts of Prairie, Arkansas and Monroe Counties, and a flood warning for the Cache River includes Jackson and Woodruff counties. Along the Ouachita River, a flood warning has been issued for areas that include Clark, Hot Spring, Calhoun, Bradley and Ouachita counties.
A flash flood warning for portions of southwest Arkansas is no longer in effect, according to the weather service.
EARLIER
Forecasters predict heavy rainfall across Arkansas on Wednesday, prompting portions of southwest Arkansas to be placed under a flood warning and much of the rest of the state under a flood watch.
The warning includes parts of Miller, Lafayette, Hempstead, Nevada and Columbia counties, according to the National Weather Service. Roughly all but the northwestern third of the state is under the flood watch, with up to 3 inches of rainfall possible in areas through this afternoon, the agency said.
If any thunderstorms develop, however, the weather service expects them to be isolated.
Cold air settling over the state Thursday night through Friday is expected to drop temperatures across central and southern Arkansas as low as the lower 20s, forecasters said. In northern Arkansas, lows are predicted to be in the teens, with a wind chill near zero.
