    Areas affected...portions of the southern/central Great Plains

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

    Valid 031902Z - 032130Z

    Probability of Watch Issuance...20 percent

    SUMMARY...Scattered to numerous strong to occasionally severe
    thunderstorms may bring a risk for isolated damaging wind gusts and
    large hail this afternoon and evening. Watch issuance is unlikely.

    DISCUSSION...Latest surface analysis depicts a surface trough
    extending southward from eastern Colorado/western Kansas into the
    Texas Panhandle, with a weak low analyzed north of Amarillo, TX.
    Visible satellite imagery depicts developing thunderstorms along
    this surface trough and an additional surface confluence zone
    extending southeastward from the Oklahoma Panhandle into western
    Oklahoma downstream of a remnant MCV evident near the NM/TX/OK
    border. Latest objective analysis and the 18z AMA/DDC observed
    soundings suggest that lingering inhibition is eroding amid
    continued diurnal heating, with MLCAPE of 1000-2000 J/kg, which will
    allow for a further increase in thunderstorm coverage through the
    afternoon.

    Modestly enhanced mid-level flow in close proximity to the
    aforementioned MCV (30+ kts at 4-5 km AGL sampled by the AMA VAD
    profile) is contributing to locally enhanced effective shear (25-35+
    kts per latest mesoanalysis). This should support marginal storm
    organization, with multicells and marginal supercell structures
    possible. The main threat with these storms will be damaging
    downburst wind gusts given steep low-level lapse rates. Isolated
    large hail will also be possible with the more robust updrafts,
    particularly across the eastern Oklahoma Panhandle into southwestern
    Kansas where enhanced effective shear downstream of the MCV overlaps
    steeper mid-level lapse rates (around 7 C/km sampled by the 18z DDC sounding).=20

    Watch issuance appears unlikely at this time owing to the
    expectation for the severe threat magnitude to remain largely
    limited, but trends will continue to be monitored.
