    Low pressure approaches today and tracks well SE of the region
    this afternoon and tonight.
    
    Light NE to E winds will increase to 10-15 kt 14-17Z with gusts
    15-20 kt possible for KJFK, KLGA, and KISP in the afternoon.
    Winds may
    
    Generally VFR conditions through the early morning. However,
    some MVFR ceilings have moved into KLGA. MVFR ceilings will
    continue to develop this morning and then lower to IFR late in
    this morning into the afternoon as precipitation overspreads
    the region. IFR conditions then expected to persist through the
    TAF period, with improvement at the tail end of the 30 hour TAF
    sites.
    
    Mainly rain is expected at most terminals, though ice pellets may
    mix in at the start for an hour or two, but the chance for
    precipitation during this timeframe is low, so added VCSH to the
    TAFs from 14-17Z to cover this possibility.
    
    Ice pellets may mix in with snow at the start for KSWF, but a
    changeover to all snow is expected after 18Z and continue through
    the evening. 2 to 4 inches of snow accumulation are forecast at KSWF
    through tonight.
    
    Precipitation moves out of the area after 06Z Monday with winds
    shifting more to the NE.
