SHOWERS AND A FEW THUNDERSTORMS OCCURRING ACROSS
THE AREA. THERE HAVE BEEN NUMEROUS REPORTS OF SLEET/HAIL
ACROSS NORTHEAST OKLAHOMA AND NORTHWEST ARKANSAS THIS

AND EJECTS NORTHEAST OUT INTO THE PLAINS. THE SHOWERS AND
THUNDERSTORMS ARE EXPECTED TO END SUNDAY NIGHT AS THE MID-LEVEL
LOW MOVES INTO THE MISSISSIPPI VALLEY. THE HEAVIEST RAIN WITH
