    Areas affected...Parts of the TX/OK Panhandles...western into
    north-central OK...south-central KS

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

    Valid 040527Z - 040800Z

    Probability of Watch Issuance...20 percent

    SUMMARY...Thunderstorms with isolated large hail and perhaps locally
    gusty winds are possible overnight.

    DISCUSSION...Elevated convection has recently developed across parts
    of the TX Panhandle, with increasing midlevel cumulus noted into far
    northwest OK. A further increase in elevated convection is expected
    with time overnight, as a mid/upper-level shortwave trough currently
    over the central/southern Rockies begins to impinge upon a reservoir
    of moderate elevated buoyancy (with MUCAPE of 1000-2000 J/kg).=20

    Steep midlevel lapse rates (as noted in regional 00Z soundings) and
    strong mid/upper-level flow (with effective shear of near/above 40
    kt) are favorable for organized elevated storms with large hail,
    potentially into the 1.5 - 2 inch diameter range. However, recent
    CAM guidance generally depicts a transition to a cluster or linear
    mode with time, which could temper the magnitude and coverage of the
    hail threat to some extent. Also, despite a substantial cool/stable near-surface layer to the north of an advancing cold front, locally
    gusty surface winds cannot be ruled out if any substantial
    clustering or upscale growth occurs.
