    ...NO SEVERE THUNDERSTORM AREAS FORECAST...

    ...SUMMARY...
    Scattered thunderstorms will be possible from portions of the
    Southwest to the central/southern High Plains and across the
    southern Ohio Valley and the Southeast. Additional shower and
    thunderstorm activity will be possible across the Pacific Northwest.
    Severe storms are generally not expected.

    On D3/Monday, guidance suggests that height rises will begin across
    the central US as a high amplitude ridge builds in from the west. An
    upper level low will begin to deepen and move inland across the
    Pacific Northwest through the period. Though instability will be
    minimal, cooling temperatures aloft with the upper low may promote a
    few thunderstorms towards the end of the period.

    Slow moisture return will continue across much of the Plains into
    the Midwest, with areas of widely scattered areas of thunderstorms
    possible across portions of the Southwest to the southern/central
    High Plains and from the southern Ohio Valley into the Southeast. A
    few strong to marginally severe storms will be possible from the
    Plains to the Southeast where better instability resides, but
    generally weak flow and subsidence aloft will keep organized storm
    potential low.
