    Mesoscale Discussion 0224
    NWS Storm Prediction Center Norman OK
    0201 PM CDT Fri Mar 22 2019

    Areas affected...East-central New Mexico into portions of the Texas
    Panhandle

    Concerning...Severe potential...Watch likely

    Valid 221901Z - 222130Z

    Probability of Watch Issuance...80 percent

    SUMMARY...The threat of damaging wind gusts, hail, and perhaps a
    tornado should gradually increase from west to east across the
    discussion area this afternoon. A WW issuance is being considered -
    most likely in the next couple of hours.

    DISCUSSION...Recent convective trends are on a general uptick near a
    lee trough on the western extent of the discussion area. These
    trends should continue given approaching ascent and cooling aloft
    associated with a shortwave centered near the Four Corners.
    Meanwhile, warming surface temperatures (low to mid 60s F) and 45-52
    F dewpoints were contributing to weak to moderate surface-based
    instability, which should reach 1000-1500 J/kg range through peak
    heating as the mid-levels continue to cool. Surface winds in
    eastern New Mexico have veered slightly, suggesting a relatively low
    tornado threat initially. However, a remnant rain-cooled boundary
    persists across the TX Panhandle from near 20 W DHT to near AMA, and
    surface winds remain backed to southeasterly in this area. As
    storms migrate into the Panhandle, the remaining boundary and modest
    increase in low-level flow may support a tornado or two, although
    the primary threats with this activity should primarily be hail and
    damaging wind gusts.
