ISOLATED SEVERE THUNDERSTORMS WILL BE POSSIBLE LATE THIS AFTERNOON AND EVENING GENERALLY EAST OF A LINE FROM MARIETTA TO PONCA CITY. THE PRIMARY THREATS WILL BE HAIL AND LOCALLY STRONG WINDS. A WEAK UPPER LEVEL TROUGH SOUTHWARD FROM AN LOW OVER NORTHEASTERN KANSAS MAY COMBINE WITH RESIDUAL LOW LEVEL MOISTURE TO PROVIDE ENOUGH INSTABILITY FOR THE DEVELOPMENT OF ISOLATED SEVERE STORMS THIS AFTERNOON AND EVENING IN THE THREAT AREA.

CENTRAL OKLAHOMA HAS ABOUT A 10 PERCENT CHANCE OF RAINFALL TODAY...TOO LOW TO MENTION IN PUBLIC FORECASTS.

NO ORGANIZED SEVERE WEATHER IS EXPECTED ANYWHERE IN THE SLIGHT RISK AREA. NO FOCUSING MECHANISM IS EVIDENT AND THE VERTICAL WIND PROFILE IS NOT FAVORABLE FOR STRONG THUNDERSTORMS. THE ONLY FACTORS FAVORING HAIL OR HIGH WINDS ARE THE RELATIVELY HIGH AMOUNTS OF LOW LEVEL MOISTURE...AND MODERATE INSTABILITY.
