    Areas affected...middle/upper Ohio Valley

    Concerning...Severe Thunderstorm Watch 85...

    Valid 012257Z - 020030Z

    The severe weather threat for Severe Thunderstorm Watch 85
    continues.

    SUMMARY...A gradual weakening trend is anticipated this evening
    across WW0085, but at least some risk for strong to occasionally
    damaging wind gusts and isolated severe hail is expected for another
    hour or so.

    DISCUSSION...Ongoing convective activity within WW85 is noted
    along/near the Ohio River. Expectation is for this activity to
    gradually weaken with time this evening as nocturnal boundary layer stabilization increases low-level inhibition. However, 500-1000 J/kg
    MLCAPE and around 30 kts of effective bulk shear (per latest
    mesoanalysis) should continue to support at least some threat for
    strong to occasionally damaging winds and isolated large hail over
    the next hour or so. The greatest short term risk appears to be
    associated with a stronger storm cluster currently located across
    northwestern West Virginia. A new watch is not anticipated at this
    time; however, a local extension may be needed should a stronger
    storm or two persist past the scheduled expiration of WW85 at 00Z.
