    Mesoscale Discussion 1496

    Areas affected...western/central OK

    Concerning...Severe potential...Watch possible=20

    Valid 110540Z - 110715Z

    Probability of Watch Issuance...40 percent

    SUMMARY...Thunderstorm clusters may pose a risk of sporadic hail to
    near 1 inch diameter and gusty winds overnight.

    DISCUSSION...Thunderstorms are developing across parts of western
    and central OK late tonight ahead of a convectively enhanced
    vorticity maxima now ejecting across the OK/TX Panhandles. This
    activity is developing in an environment with MUCAPE around
    1500-2500 J/kg and effective shear near 30 kt. A 05z RAOB from OUN
    also shows steep midlevel lapse rates are present, but SB/ML CINH
    are also large. This may support briefly intense cores capable of
    producing hail. Regional VWP data and 850 mb RAP objective analysis
    indicates only modest low-level flow. Strong low-level inhibition
    and the absence of a stronger low-level jet to aid in storm
    organization should limit severe potential to a couple of briefly
    intense cells. Sporadic hail and gusty winds will be the main
    concern with this activity over the next few hours. While a severe
    thunderstorm watch does not appear likely at this time, trends will
    be monitored and a watch could be issued if better storm
    organization can occur.
