    Mesoscale Discussion 1218
    NWS Storm Prediction Center Norman OK
    0114 AM CDT Mon Jun 09 2025

    Areas affected...parts of east-central/southeast Texas

    Concerning...Severe potential...Watch possible=20

    Valid 090614Z - 090745Z

    Probability of Watch Issuance...60 percent

    SUMMARY...A severe thunderstorm watch may be needed south of watch
    399.

    DISCUSSION...A southward moving line of storms from northeast Texas
    to north-central Texas will pose some severe weather threat through
    the early morning hours Monday. 2000 to 3000 J/kg MUCAPE and 40
    knots of effective shear should provide sufficient
    instability/organization for this line of storms to persist through
    the morning. The line is broken across central Texas with some more
    organized segments southeast of Dallas and more supercellular
    structure southwest of Fort Worth. Some guidance, such as the HRRR,
    suggests that these supercells across central Texas may congeal into
    a cluster and move southeast toward College Station. If this occurs,
    a greater severe weather threat may materialize across east-central
    Texas. However, if the storms remain somewhat spaced and well behind
    the gust front, a more organized severe wind threat seems more
    uncertain.

    Trends will be monitored and a downstream severe thunderstorm watch
    may be needed.
