    Areas affected...Red River Valley and vicinity

    Concerning...Tornado Watch 195...

    Valid 300539Z - 300715Z

    The severe weather threat for Tornado Watch 195 continues.

    SUMMARY...Scattered strong to severe storms producing hail or
    locally severe gusts will remain possible across the region, and a
    severe thunderstorm watch may be needed as the tornado watch expires
    at 0600Z.

    DISCUSSION...A large MCS continues to push east across OK, with rear-inflow/confluence bands developing westward along I-40.
    Meanwhile, sporadic supercells with hail cores persist over
    northwest TX and along the Red River, near the deeper outflow
    boundary.

    Given persistent southerly flow at 850 mb with a moist and unstable
    air mass, additional severe cells may redevelop within this zone
    tonight. As such, a severe thunderstorm watch will likely be needed.

    Otherwise, severe storms continue to develop west of this area
    inside WW 0195. With time, much of this activity could merge into
    yet another MCS.
