    Areas affected...Southern New England

    Concerning...Severe potential...Watch likely

    Valid 151758Z - 152000Z

    Probability of Watch Issuance...95 percent

    SUMMARY...Storms will move in from the west with an increasing
    threat of severe weather later this afternoon. Wind, hail, and
    perhaps a tornado will all be possible.

    DISCUSSION...Visible imagery shows strong heating occurring over the
    region with temperatures approaching 80 F as of 18Z. Storms were
    forming over southern NY within the low pressure trough, and an
    eastward extension of this trend is expected. Increasing winds aloft
    with the shortwave trough will favor organized convection capable of
    damaging winds and hail. A tornado risk may also exist from CT into
    central MA where surface winds are locally backed.

    Areas affected...Far West Texas

    Concerning...Severe potential...Watch possible

    Valid 232152Z - 232345Z

    Probability of Watch Issuance...60 percent

    SUMMARY...Storm intensity in far West Texas may increase in the next
    few hours, watch issuance/extension possible.

    DISCUSSION...Regional radar shows a marginally severe storm entering
    far West Texas. This convection is expected to remain somewhat
    disorganized in the short term, as it currently resides within a
    weakly buoyant (MLCAPE < 1000 J/kg) and weakly sheared sheared
    (Effective Bulk Shear < 30 kt) environment. The latest surface
    analysis shows richer boundary-layer moisture to the east, with dew
    point temperatures of 50+ F near Pecos, TX, and 60+ F near
    Sanderson, TX. Consequently, MLCAPE values range from 1000-1500 J/kg
    downstream of the current convection to go along with effective bulk
    shear of 50+ kt. The latest high resolution model guidance suggests
    an increase in easterly upslope flow, which would help to increase
    access to richer buoyancy to any storms propagating across this
    region. Should this occur, the environment will be more conducive to
    sustain severe intensity. Thus, a watch or a watch extension may be
    needed.
