    Areas affected...Parts of central Oklahoma

    Concerning...Tornado Watch 213...

    Valid 120301Z - 120430Z

    The severe weather threat for Tornado Watch 213 continues.

    SUMMARY...The supercell tornado threat is spreading eastward across
    Tornado Watch 213.

    DISCUSSION...Latest radar imagery from KTLX shows three discrete
    supercells tracking east-northeastward across parts of McClain,
    Cleveland, and Pottawatomie Counties tonight. Backed surface winds
    and lower 70s dewpoints beneath a 30-kt low-level jet (per TLX VWP)
    will support the maintenance of these supercells in the near-term --
    with an associated tornado risk.=20

    Despite nocturnal boundary-layer cooling, the rich low-level
    moisture in place ahead of these storms could support continued
    surface-based inflow with eastward extend tonight. Therefore, an
    extension of Tornado Watch 213 may be warranted, and areas
    downstream will be monitored.
