    Mesoscale Discussion 0131

    Areas affected...Northeast Oklahoma into southern Missouri and
    northwest Arkansas

    Concerning...Severe potential...Watch unlikely=20

    Valid 041349Z - 041545Z

    Probability of Watch Issuance...20 percent

    SUMMARY...A few stronger storms are capable of large hail and severe
    wind gusts this morning.

    DISCUSSION...Storm coverage has increased across northeast Oklahoma
    and southwest Missouri this morning in close proximity to a
    shortwave trough moving across southeast Kansas and northern
    Oklahoma. The elevated instability environment southwest of where
    these storms are forming was well sampled by the OUN 12Z RAOB.
    MUCAPE in excess of 2000 J/kg and mid-level lapse rates around 8 to
    8.5 C/km were sampled. The SGF RAOB sampled around 1300 J/kg MUCAPE
    which may be more representative of the environment these storms
    have developed within. This thermodynamic environment combined with
    stronger shear farther northeast (~55 knots 0-6km per INX VWP) will
    support the potential for mostly elevated supercells capable of
    large hail and perhaps severe wind gusts. This threat will likely
    persist for a few hours this morning as storms move along and north
    of the surface boundary.
