    Areas affected...northeastern New York into Vermont

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

    Valid 121545Z - 121815Z

    Probability of Watch Issuance...20 percent

    SUMMARY...Isolated strong to severe storms cannot be ruled out this
    afternoon from northeastern New York into Vermont. A brief/weak
    tornado or locally strong gusts will be possible.

    DISCUSSION...Visible satellite shows areas of clearing, which is
    allowing for relatively warm conditions to develop. Surface
    temperatures are already in the upper 60s F, which is warmer than
    several models indicate. This has led to the development of several
    hundred J/kg SBCAPE.

    Area VWPs show 0-1 SRH over 200 m2/s2, which is quite supportive of
    rotation within storms. This, along with a relatively high RH
    boundary layer, and lift ahead of the front/surface trough, suggest
    an uptick in at least low-topped thunderstorm coverage may occur.
    Whether individual cells form, or north-south line segments, storms
    may acquire sufficient low-level rotation for a brief tornado risk,
    within a small zone where heating is most prominent.
