    Areas affected...Parts of southwest Oklahoma

    Concerning...Tornado Watch 182...

    Valid 290155Z - 290300Z

    The severe weather threat for Tornado Watch 182 continues.

    SUMMARY...Supercell tornado potential is likely peaking over the
    next hour or two.

    DISCUSSION...After several storm mergers into a cluster of
    supercells over southwest OK -- to include a left-mover that
    produced 3-inch hail, the latest radar data has shown signs that
    right-movers are attempting to become dominant. This is in response
    to the strengthening low-level jet and related enlargement of
    clockwise-curved hodograph sampled by the FDR VWP (around 270 m2/s2
    0-500m SRH). While uncertainty remains in the overall tornado risk,
    given the continued messy mode, recent trends and environmental data
    suggest that the right movers could mature and pose an increased
    tornado risk over the next hour or two.
