    Areas affected...Far northeast New York...northern Vermont and New Hampshire...and into central Maine

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

    Valid 072003Z - 072200Z

    Probability of Watch Issuance...20 percent

    SUMMARY...Isolated strong thunderstorms may pose a severe wind/hail
    risk through the afternoon and early evening hours. This threat is
    expected to remain sufficiently isolated to preclude watch issuance.

    DISCUSSION...Latest regional radar imagery shows a gradual
    maturation of convection across far northeast NY and across central
    ME along/ahead of a cold front. Temperatures warming into the low
    80s with dewpoints in the upper 60s to low 70s is slowly eroding
    inhibition with MLCAPE increasing to around 500-1000 J/kg region
    wide. This warming trend should continue and will promote further
    thunderstorm intensification over the next couple of hours. 30-40
    knot mid-level winds in proximity to a weakening upper trough are
    supporting sufficient hodograph elongation for organized convection.
    While convective mode will likely transition to predominantly a
    semi-organized convective band due to strong flow along the
    initiating cold front, an initial supercell or two appears possible
    and may pose a severe hail/wind risk through the afternoon -
    especially across central ME where forcing for ascent is currently
    more nebulous. With time, strong to severe winds should become the
    predominant hazard as a band of storms begins to emerge. Despite
    these concerns, the overall severe threat is expected to remain
    sufficiently isolated to preclude watch issuance.
