    Areas affected...eastern Oklahoma into far western Arkansas

    Concerning...Severe potential...Watch unlikely

    Valid 040806Z - 041030Z

    Probability of Watch Issuance...5 percent

    SUMMARY...Storms are expected to increase near a cold front, with
    only small hail or gusty winds expected.

    DISCUSSION...Radar shows a thin line of showers and soon-to-be
    thunderstorms near or just behind a cold front from south-central
    into northeast OK. While mid to upper 60s F dewpoints remain within
    the boundary layer to the east, overall instability is minimal owing
    to weak lapse rates aloft due to midlevel subsidence. CAMs do
    suggest an increase in intensity over the next several hours,
    however, storms are unlikely to become severe. Small hail or perhaps
    gusty winds will be possible.

    Areas affected...Portions of southern/eastern Ohio...eastern
    Kentucky...western West Virginia...western Pennsylvania

    Concerning...Tornado Watch 63...65...

    Valid 142049Z - 142245Z

    The severe weather threat for Tornado Watch 63, 65 continues.

    SUMMARY...Storms in the western portions of Tornado Watch 63 have
    generally struggled to maintain intensity as winds have veered and
    dewpoints have decreased. Ongoing storms in the eastern half of the
    watch will continue, particularly into western Pennsylvania/western
    New York. A downstream watch for the continued severe threat is
    likely.

    DISCUSSION...Storms within Tornado Watch 63 have generally taken on
    a linear mode with a few embedded supercell structures. Behind the
    main line of activity just east of Columbus, OH, winds have veered
    and dewpoints have fallen to the low to mid 50s. Storms in the
    western portions of the Watch may pose a marginal hail/wind gust
    threat, but otherwise struggle to maintain intensity with the
    deteriorating boundary layer conditions. In the east, portions of
    West Virginia have struggled to destabilize with cloud cover for
    much of the day and further influence from convection to the
    southeast. However, continued approach of mid-level forcing may help
    maintain storm intensity longer than anticipated in those locations.

    Richer boundary layer moisture will exist for storms moving out of
    Ohio and into western Pennsylvania/far western New York. Some CAM
    guidance continues to show a linear MCS moving across this region. A
    downstream watch will likely be issued for this activity given the
    continued strong deep-layer shear expected through the evening.
