    A band of light to moderate rain continues to push
    east this morning. Low ceilings ranging from 500 to 1500 feet and
    visibilities of 3 to 5 miles are accompanying this band of rain as
    it moves through. The rain band should finally clear KGPT by 00z.
    Farther to west, some dry air intrusion after the rain ends around
    20-22z will allow ceilings to improve into MVFR range of 1500 to
    3000 feet for the evening hours. However, an inversion is expected
    to develop tonight that will trap lingering low level moisture in
    place and promote the development of low ceilings late this
    evening through the overnight hours. Expect to see ceilings fall
    back into the 500 to 1500 foot range resulting in a mix of IFR and
    MVFR conditions. All terminals should drop into fuel alternate
    levels during the overnight hours. The cloud cover should quickly
    clear out tomorrow morning as drier air mixes down into the
    boundary layer with VFR conditions prevailing at all terminals
    shortly after sunrise. PG
