The National Weather Service allowed a tornado watch for parts of western and central Oklahoma to expire tonight, but a watch is active in northern parts of the state until 4 a.m. as thunderstorms continue to affect the area.
The watch is effective in Alfalfa, Garfield, Grant, Harper, Kay, Major, Noble, Woods and Woodward counties. A small but powerful storm was moving northeast near Waynoka about 10 p.m., weather service radar imagery showed. No other storms were visible.
Spotters reported tennis ball-sized hail near Hollis about 8:05 p.m. and up to baseball-sized hail near Woodward about 8:50 p.m.
Other thunderstorms could form over the northern third of the state overnight, forecasters said. Large hail, heavy rainfall and tornadoes are possible.
At 10 p.m., about 8,000 Oklahoma Gas & Electric Co. customers still were without power, down from about 12,000 seven hours earlier. About 7,000 utility customers remained without power in the Oklahoma City area.
