    Areas affected...Central High Plains

    Concerning...Severe Thunderstorm Watch 240...

    Valid 262233Z - 270030Z

    The severe weather threat for Severe Thunderstorm Watch 240
    continues.

    SUMMARY...Damaging winds will be the primary threat from parts of
    eastern Colorado into southeast Wyoming and the Nebraska Panhandle.
    Isolated large hail and perhaps a brief tornado are also possible,
    especially with more discrete storms.

    DISCUSSION...Convection has become more linear across eastern
    Colorado into southeastern Wyoming. A few discrete elements remain
    in southeastern Colorado where effective shear is greater. Though
    upper-level forcing is modest, storms should be able to propagate
    into a moist, unstable airmass in the High Plains. Damaging winds
    (most likely 45-55 kts) will be the main concern. Discrete storms in southeastern/east-central Colorado could also produce isolated large
    hail. Low-level southeasterly winds and a slight increase in 850 mb
    winds this evening will help to maintain moisture in the region and
    provide just enough hodograph curvature for a brief tornado or two.
    Activity will likely persist for a few more hours before
    encountering less unstable conditions in western Kansas/Nebraska.
