POTENTIAL TO BECOME SEVERE.
MORE THUNDERSTORMS ARE EXPECTED TO DEVELOP ACROSS NORTHERN
OKLAHOMA FRIDAY AFTERNOON ALONG A DRYLINE, AHEAD OF AN UPPER
STORM SYSTEM AND ASSOCIATED SURFACE LOW PRESSURE AND COLD FRONT.
THESE STORMS WILL HAVE A DECENT CHANCE OF BECOMING SEVERE IN AN
UNSTABLE AND STRONGLY SHEARED ENVIRONMENT, AND WOULD BE CAPABLE OF
PRODUCING HIGHER-END SEVERE WEATHER. THIS INCLUDES VERY LARGE
HAIL, LOCALLY DAMAGING WIND AND TORNADOES. EVENTUALLY, THE COLD
FRONT WILL OVERTAKE THE DRYLINE AND WILL FORCE A BAND OF STORMS
ALONG IT, WITH A DAMAGING WIND THREAT FRIDAY NIGHT.
