    Areas affected...parts of Vermont and upstate New York

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

    Valid 032238Z - 040015Z

    Probability of Watch Issuance...20 percent

    SUMMARY...A few damaging gusts are possible this evening across
    parts of Vermont and upstate New York with storms ahead of a cold
    front. A watch is not anticipated.

    DISCUSSION...Clear skies have allowed a corridor of instability to
    develop ahead of a cold front across parts of Vermont and upstate
    New York, and a few storms have developed along this front. VAD wind
    profiles from KCXX indicate somewhat weak deep-layer shear, leading
    to multicell clusters and line segments observed on radar. Regional
    RAP profiles indicate nearly dry-adiabatic lapse rates in the lowest
    2 km AGL. This, when combined with the modest low-level flow, may
    produce a threat for damaging gusts this evening, particularly with
    clusters of convection. However, the coverage is expected to be
    sparse, and the threat is expected to wane with the loss of
    sunlight. Therefore, a watch is not anticipated with this activity.
