    Areas affected...southern IN into north-central KY

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

    Valid 011343Z - 011515Z

    Probability of Watch Issuance...5 percent

    SUMMARY...Locally strong gusts and small hail may accompany storms
    storms shifting east this morning. A severe thunderstorms watch is
    not expected at this time.

    DISCUSSION...A cluster of storms is shifting east this morning
    across southern IN along the apex of stronger instability nosing
    into central KY. Surface dewpoints in the upper 60s F and midlevel
    lapse rates around 7 C/km are contributing to MUCAPE values around
    1500-2000 J/kg. However, quite a bit of boundary-layer inhibition is
    still in place given time of day, and low-level lapse rates remain
    weak as only modest surface heating has occurred so far. Ahead of
    the line of storms, clusters of showers and thunderstorms are
    developing across central KY. This downstream activity and overall
    poor boundary-layer conditions, severe potential is expected to
    remain limited over the next couple of hours. Locally strong gusts
    to 45 mph and small hail will be possible, but a severe thunderstorm
    watch is not expected at this time.
