    Areas affected...Eastern PA into southern New England

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

    Valid 041927Z - 042130Z

    Probability of Watch Issuance...20 percent

    SUMMARY...The threat for primarily isolated damaging gusts will
    spread northeastward this afternoon.

    DISCUSSION...Sporadic damaging winds and observed gusts up to 40-45
    mph have been noted recently when convection spreading northeastward
    across northeast PA into central/southern NY. Deep-layer shear
    remains weak across the region, but unidirectional southwesterly
    flow will continue to support occasionally vigorous redevelopment
    along a northeastward-propagating cold pool. Moderate downstream
    instability (MLCAPE of 1500-2000 J/kg) and steep low-level lapse
    rates will continue to support a threat of localized damaging wind
    gusts as storms spread toward southern New England through the
    afternoon. With the threat still expected to be relatively
    disorganized, watch issuance remains unlikely.

    Areas affected...Southwest Kansas...Oklahoma Panhandle...northern
    Texas Panhandle...northwest Oklahoma

    Concerning...Severe Thunderstorm Watch 527...

    Valid 202149Z - 202345Z

    The severe weather threat for Severe Thunderstorm Watch 527
    continues.

    SUMMARY...All severe hazards will be possible late this afternoon
    and evening. Very large hail threat will focus in southwest Kansas
    near Dodge City. Tornado threat will focus along a surface boundary
    in the combined Panhandles. The primary hazard will eventually be
    severe (potentially significant) wind gusts as an MCS organizes and
    moves out of southeast Colorado.

    DISCUSSION...An ongoing, intense supercell continues across parts of
    southwest Kansas just north of Garden City. Hail of 1.75-2.5 inches
    has already been reported with this storm and current dual-pol radar presentation from KDDC would suggest very large hail remains a
    potential threat. Furthermore, a tornado has been reported with this
    storm as well. This storms and any other that develop nearby are the
    greatest short-term severe threat.

    Later this evening, convection that is ongoing in eastern Colorado
    is expected to grow upscale. Temperatures near 90F and dewpoints in
    the upper 60s to low 70s F will support moderate to strong buoyancy
    late this afternoon and evening. Combined with strong northwesterly
    effective shear, this environment will support potential for an
    intense line of storms capable of scattered severe wind gusts (some
    of which may exceed 75 mph). Given the linear storm mode expected,
    the tornado threat will be somewhat modulated. The greatest threat
    for a tornado or two would be along and just north of the surface
    boundary into the Texas/Oklahoma Panhandles.
