    Mesoscale Discussion 1251

    0239 PM CDT Wed Jun 11 2025

    Areas affected...Northeast TX into western LA and far southwest AR

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

    Valid 111939Z - 112145Z

    Probability of Watch Issuance...5 percent

    SUMMARY...Gusty winds are possible the remainder of the afternoon as
    a line of storms tracks northeast across the ArkLaTex vicinity.

    DISCUSSION...A line of storms has maintained organization along
    surging outflow as convection moves through a corridor of weak to
    moderate instability this afternoon. Some embedded stronger cells
    within this line are likely aided by 25-30 kt effective shear
    magnitudes within the unstable airmass. Precipitable water values
    near 2 inches may further aid in sporadic wet microbursts, and
    locally strong gusts will be possible the remainder of the
    afternoon. Overall severe potential is expected to remain limited,
    and a watch is not expected at this time.
