LARGE HODOGRAPHS WITH 0-1 KM STORM RELATIVE HELICITY FROM 200-300

CONTINUE TO PROMOTE SUPERCELLS WITH LOW LEVEL MESOCYCLONES. GIVEN
THE PROPENSITY TO MAINTAIN DISCRETE STORMS WITHIN THE FAVORABLY
SHEARED AND MODERATELY UNSTABLE ENVIRONMENT...SOME SUPERCELLS WILL
REMAIN CAPABLE OF PRODUCING STRONG TORNADOES NEXT FEW HOURS.
