    Areas affected...portions of central and southern Oklahoma

    Concerning...Severe Thunderstorm Watch 372...

    Valid 220630Z - 220830Z

    The severe weather threat for Severe Thunderstorm Watch 372
    continues.

    SUMMARY...An intense bow echo will continue moving rapidly southeast
    across central Oklahoma, including the Oklahoma City metro, and into south-central Oklahoma through 3:30 am CDT. Significant severe wind
    gusts, with peak winds between 85 and 100 mph, are likely.

    DISCUSSION...An intense bow echo, with a well-organized rear-inflow
    jet, continues moving rapidly southeast at around 45 mph, with a
    history of significant severe gusts exceeding 100 mph. The
    environment downstream of this convective system remains supportive
    of a continued significant severe wind event, with a very moist air
    mass contributing to MUCAPE in excess of 3000 J/kg and moderate
    west/northwest mid-level flow. Latest hi-res guidance supports the
    scenario of an intense bowing complex moving through central
    Oklahoma through 3:30 am CDT/0830z, with some increase in the
    lateral extent of the strong winds as the cold pool expands. In
    addition to widespread severe winds, the environment will continue
    to support short-lived leading edge circulations and an attendant
    tornado risk.
