    Areas affected...Central/Southern Oklahoma

    Concerning...Severe Thunderstorm Watch 31...

    Valid 240110Z - 240315Z

    The severe weather threat for Severe Thunderstorm Watch 31
    continues.

    SUMMARY...Severe threat continues for WW31 with large hail, strong
    wind gusts, and perhaps a brief/weak tornado possible.

    DISCUSSION...Multiple severe thunderstorms are moving east/northeast
    across central/southern Oklahoma. There remains a corridor east of
    the dryline to approximately a line stretching from Tulsa to the Red
    River where storms will remain surface-based. Effective bulk shear
    of 40-50 knots and 250-800 J/kg of MLCAPE are within this warm
    sector according to mesoanalysis. While the severe threat will begin
    to diminish later this evening, established severe storms could
    still produce large hail even as storms become elevated. While
    strong wind gusts and a brief/weak tornado are possible, large hail
    continues to be the primary severe threat during the next couple of
    hours. A watch extension is unlikely at this time given the marginal
    severe environment east of the watch and beyond expiration time.
