    Concerning...Severe Thunderstorm Watch 208...

    Valid 020703Z - 020900Z

    The severe weather threat for Severe Thunderstorm Watch 208
    continues.

    SUMMARY...The threat of severe gusts and hail remains over the
    entire watch area, with brief tornadoes, sporadic very large hail,
    and perhaps locally significant gusts over southern Oklahoma and
    along the Red River Valley.

    DISCUSSION...Storms have rapidly increased in coverage across much
    of western through southern OK, as the influence of the upper trough
    and cooling aloft overspread the moist and unstable air mass. The
    greatest threat area should continue to be over southern parts of
    the watch, in proximity to the stationary front. Here, both
    moisture, instability and convergence are maximized. Very large
    storms have evolved out of this developing cluster, with new cells
    just east of the primary supercell. Given the strong instability,
    low-level shear may be sufficient to support periodic mesocyclones
    and brief tornadoes. The primary risk will more likely be damaging
    wind and hail, both of which could be locally significant.

    For northern areas, the storms associated with the cold pool surge
    out of the west may continue to produce at least near-severe gusts.
    Although the low-level jet is not strong this evening, a very slow
    northward push of elevated moisture, coupled with steep lapse rates
    aloft, could conceivably aid some strengthening over time.
