    Areas affected...Northeast New York into Vermont

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

    Valid 101900Z - 102100Z

    Probability of Watch Issuance...20 percent

    SUMMARY...Thunderstorms are beginning to show signs of
    intensification. Damaging winds and large hail will be possible
    through the afternoon, but confidence in thunderstorm coverage
    remains low. Watch issuance is not anticipated at this time.

    DISCUSSION...Weak convection has been percolating across northeast
    NY and VT since late morning, but has recently shown some signs of intensification per GOES IR imagery and vertically integrated
    liquid/echo top trends. Some degree of intensification is probable
    as daytime heating continues for the next several hours and MLCAPE
    increases to around 1000 J/kg. Elongated anvils are noted with
    deeper convection, which confirms recent forecast soundings that
    suggest upper-level winds are around 35-45 knots. However, winds
    through much of the CAPE-bearing layer remain near/below 20 knots,
    which is confirmed by recent VWP observations. Given the modest
    lapse rates/buoyancy, it remains unclear whether updrafts will be
    deep enough to sufficiently realize the stronger winds aloft and
    take on more organized supercell structures, especially given
    nebulous forcing for ascent/weak dynamic mid-level cooling.
    Consequently, a few strong/severe storms appear possible, but
    confidence in the overall coverage and longevity of severe
    convection remains limited. Trends will continue to be monitored,
    but watch issuance is currently not anticipated.
