    Areas affected...northern Oklahoma

    Concerning...Tornado Watch 215...

    Valid 272025Z - 272200Z

    The severe weather threat for Tornado Watch 215 continues.

    SUMMARY...Storms will remain capable of producing large to very
    large hail, damaging wind and a couple tornadoes next couple hours
    mainly across the northern half of Oklahoma.

    DISCUSSION...As of mid afternoon storms continue developing across
    northern OK. Most thunderstorm development has become confined to
    the cool side of a couple of outflow boundaries. These storms are
    probably slightly elevated, but will remain capable of producing
    mainly isolated large hail and damaging wind. Farther west
    additional storms are beginning to develop along the cold front
    across northwest OK. These storms will be surface based and will
    likely become rapidly severe and organized as supercells shortly
    after initiation. VWP from Twin Lakes show the mid-level winds have strengthened to 50 kt and size of low-level hodographs has increased
    slightly. The best potential for isolated tornadoes will probably be
    with storms that initially develop across western and west central
    OK then move east and interact with the modifying outflow boundary
    before becoming slightly elevated as they move deeper into the
    cooler side of the boundary.
