    The following discussion is for KPHL, KPNE, KTTN, KABE, KRDG,
    KILG, KMIV, KACY and surrounding areas.
    Rest of tonight...Generally VFR, but potential for sub-VFR
    conditions in periodic showers, especially between 06Z and 12Z,
    in immediate advance of a strong cold front moving through the
    area. Southwest winds 15 to 25 kts with gusts 30+ kts will
    rapidly switch to west or west-northwest 20 to 30 kts with gusts
    to 40+ kts after frontal passage. Showers may also contain
    strong/erratic/variable wind gusts and convective turbulence.
    Confidence in CIGs is well below average and in winds is
    somewhat below average, especially regarding the timing of the
    frontal passage.
    Sunday...Rapid improvement to VFR with showers quickly exiting
    the area early in the morning. Very strong west or west-
    northwest winds 20 to 30 kts with gusts to 40 kts or so are
    possible through the day, with the strongest winds generally in
    the morning. Confidence is well above average.
    Sunday night...VFR with west winds slowly diminishing to around
    10 kts after midnight. Gusts to 25 kts or so possible through
    the evening hours. Confidence above average.
    Monday through Tuesday...VFR. West winds 10-15 KT on Monday
    become S 5-10 KT Monday night, and then 10-15 KT with gusts up
    to 20 KT on Tuesday. High confidence.
    Tuesday night through Thursday...Potential for rain Tuesday
    night/Wednesday, then again on Thursday with sub-VFR conditions.
