    Mesoscale Discussion 2210

    Areas affected...Northwest Texas into far southern Oklahoma

    Concerning...Severe potential...Watch unlikely=20

    Valid 192303Z - 200100Z

    Probability of Watch Issuance...20 percent

    SUMMARY...Thunderstorms are expected to gradually increase in
    intensity and coverage through the evening hours. Isolated to
    scattered severe thunderstorms are possible, and will mainly pose a
    large hail threat.

    DISCUSSION...GOES imagery over the past 40 minutes reveals a pair of
    deeper convective updrafts along/north of the I-20 corridor with shallower/weaker cells closer to the DFW metro area. This comes as
    ascent ahead of a large-scale upper wave gradually overspreads the
    region where capping has become very weak/negligible owing to warm
    surface temperatures in the upper 70s and low 80s. Broad-scale
    ascent will continue to increase through the evening as the wave
    shifts east, resulting in a gradual increase in thunderstorm
    coverage through the evening across northern TX into the Red River
    Valley. Modest mid-level lapse rates will likely favor a slow uptick
    in convective intensity, but strong mid/high-level flow will provide
    adequate deep-layer shear for organized convection, including the
    potential for splitting supercells once storms become sufficiently
    deep. Given weak flow in the lowest few kilometers (per regional
    VWPs) the primary risk should be large hail (most likely 1 to 2
    inches), though sporadic severe winds are also possible. It remains
    somewhat unclear how many intense storms will emerge across northern TX/southern OK due to the potential for destructive storm
    interactions/upscale growth; however, this region may be the
    relatively best corridor for severe storms over the next few hours.
    Watch issuance is not imminent, but trends will be monitored.
