    Areas affected...DFW Vicinity

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

    Valid 230121Z - 230215Z

    Probability of Watch Issuance...5 percent

    SUMMARY...A brief tornado is possible for the next 1-2 hours near
    DFW. No WW is expected for this conditional, short-duration threat.

    DISCUSSION...A couple of stronger updrafts have developed southeast
    of the DFW metro. This activity and a somewhat favorable low-level
    wind profile are associated with an MCV in central Texas. TDAL shows
    around 100 m2/s2 SRH on its VWP. These showers/storms have seen
    lightning activity dwindle with time, but low-level rotation has
    seen a small uptick recently. While the tornado threat is still
    quite low, a brief spin-up could occur within the next hour or two
    before storm depth/intensity lessens with increasing low-level
