    The following discussion is for KPHL, KPNE, KTTN, KABE, KRDG, KILG,
    KMIV, KACY and surrounding areas.
    Tonight...Ceilings quickly lower to MVFR and IFR as
    precipitation overspreads the region from southwest to
    northeast. All rain expected at MIV and ACY; a snow/rain mix may
    occur at ILG, PHL/PNE to TTN at the onset then all rain; RDG
    and ABE start as snow then quickly go over to sleet and freezing
    rain then rain overnight. Main snow and ice accumulations occur
    at RDG and ABE. Low confidence on the timing of the
    precipitation type changes. Easterly winds around 10 knots,
    turning southeast or south toward morning (some gusts to 20-25
    knots possible overnight mainly at ACY). A low-level southerly
    jet around 2000 feet overnight into early Sunday of 40-50 knots
    results in low-level wind shear.
    Sunday...MVFR/IFR conditions to start, then rapidly improving by
    late morning or afternoon as the precipitation ends. An abrupt wind
    shift to the northwest occurs by midday with winds increasing to 15-
    25 knots with gusts to around 35 knots (highest during the
    afternoon/evening). Low confidence on timing for improvement to
    Sunday night and Monday...VFR. Northwest winds 15-20
    knots with gusts to around 30 knots, diminishing Monday night.
    Tuesday...VFR. Northwest winds 10-20 knots, diminishing by late
    Wednesday and Thursday...Sub-VFR conditions possible with the chance
    for some snow to a rain/snow mix.
