    Areas affected...portions of central TX

    Concerning...Tornado Watch 278...

    Valid 130233Z - 130330Z

    The severe weather threat for Tornado Watch 278 continues.

    SUMMARY...Three supercells across portions of central into
    north-central Texas may continue to pose a large hail risk beyond
    03z/10 pm CDT.

    DISCUSSION...Three supercells persist across parts of central into north-central TX this evening. The middle supercell over Mills
    County has shown some recent intensification and better organization
    as it tracks near the surface front. Meanwhile, the northern
    left-mover and southern right-mover have been near steady state over
    the past 30 minutes or so and may be producing large to very large
    hail. Regional VWP data suggest some modest increase of a low-level
    jet has occurred this evening and is likely supporting continued
    organization of this activity.=20

    This activity is expected to become elevated with time as
    boundary-layer inhibition increases with loss of daytime heating.
    But isolated large hail may continue to be concern in the short
    term. Some tornado risk could still accompany the middle supercell
    in the vicinity of the surface boundary where low-level shear in
    maximized, but this too is expected to be short lived given
    increasing low-level inhibition this evening. Given trends, ongoing
    watch may need to be extended or, a new, small severe thunderstorm
    watch is being considered.
