    Mesoscale Discussion 1848

    Areas affected...Colorado Front Range

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

    Valid 301810Z - 302015Z

    Probability of Watch Issuance...5 percent

    SUMMARY...Scattered thunderstorms capable of isolated occurrences of
    severe hail or severe wind gusts will be possible this afternoon
    across the Colorado Front Range into portions of the Eastern
    Colorado Plains. Given the localized nature of any severe threat,
    weather watch issuance is not expected at this time.

    DISCUSSION...Daytime heating and boundary-layer mixing over the
    Central and Front Range of the Rocky Mountains has resulted in
    widespread thunderstorm development that is expected to continue and
    persist into eastern Colorado. With most unstable CAPE only reaching
    500-1000 J/kg and a relative dearth of deep-layer vertical shear,
    there is not much environmental support for widespread organized
    severe convection. However, with freezing levels near the
    surface-based parcel LFC heights, and inverted-V boundary layer
    profiles evident in proximity soundings, some isolated incidents of
    <=3D 1.25 in hail and severe wind gusts (largely <=3D 60 MPH) are
    possible. Some locally higher wind gusts could occur if any
    convection develops leading-edge outflow or shows signs of transient organization into linear clusters.
