THROUGH THE DAY TODAY...A NEARLY STATIONARY WARM FRONT REMAINS DRAPED ACROSS ARKANSAS FROM FORT SMITH TO MOUNTAIN HOME. THIS FRONT WILL CONTINUE TO WOBBLE THROUGH THE DAY BEFORE LIFTING MORE TO THE NORTH BY LATER THIS AFTERNOON AND EVENING. SURFACE LOW WILL CONTINUE TO PUSH TO THE NORTHEAST...AT THIS POINT...DID SLOW DOWN THE TIMING OF THE MAIN LINE OF PRECIP. LATEST RUNS OF HRRR HAS A FEW STRONGER STORMS DEVELOPING ACROSS OKLAHOMA AND FOLLOWING CLOSE TO WHERE THE STATIONARY FRONT IS CURRENTLY LOCATED. THE LARGEST THREAT WITH THESE INITIAL STORMS WILL BE LARGE HAIL...WITH DAMAGING WINDS...AND PERHAPS EVEN A TORNADO POSSIBLE. THE TORNADO THREAT IS FAIRLY LOW WITH THESE STORMS...WITH FAIRLY HIGH LCL VALUES. SOME OF THE HIRES MODELS DO SUGGEST THESE MAY FALL A BIT...BUT NOT UNTIL LATER IN THE EVENING.

LARGE HAIL AND DAMAGING WINDS WILL AGAIN BE POSSIBLE...BUT TORNADOES WILL BE LIMITED AS THE COLD FRONT QUICKLY OUTRACES THE STORMS.
