    Areas affected...southeast Oklahoma into northeast Texas

    Concerning...Tornado Watch 702...

    Valid 032252Z - 040115Z

    The severe weather threat for Tornado Watch 702 continues.

    SUMMARY...The threat of damaging gusts and a couple tornadoes
    persists across the watch area, with perhaps a greater risk across
    the Red River Valley.

    DISCUSSION...A large mass of rain and thunderstorms currently
    extends form south-central OK into northern TX, oriented southwest
    to northeast and primarily north of the outflow boundary/stationary
    front. While favorable shear exists north of the boundary, cooler
    temperatures are mitigating the overall threat at this time.

    Farther south into TX, a very moist air mass is in place with PWAT
    ranging from 1.50 to 2.00" into northeast TX. Given continued
    southerly low-level flow, this warm advection regime will persist
    across the stationary front, which eventually may return north later
    this evening.=20

    At this time, storms have shown a disorganized structure in terms of
    severe threat. However, the most favorable zone in a relative sense
    is across the Red River Valley and surrounding counties, as the
    ongoing activity translates east. Storm cores along the theta-e
    gradient may pose a risk of damaging winds with the bowing
    structures. Additional single-cells cannot be ruled out forming
    ahead of the main band of storms, as the air mass is uncapped. A
    brief tornado threat could occur with any activity interacting with
    the boundary. If the front begins moving north, then storms may
    acquire rotation along it over a longer period of time.
