Aviation Forecast Discussions Data
Select Site:


    (For the 18z TAFs through 18z Thursday Afternoon)
    Issued at 1220 PM CDT Wed Apr 25 2018
    VFR conditions are expected to prevail at the TAF sites for much
    of the valid period. Only exception is anticipated to be a small
    area of MVFR CIGs located just NE of STL metro slowly advecting to
    the SW in the ambient light N-NE flow. This area is now expected
    to impact STL and CPS for up to a few hours this afternoon and
    will be monitored if it will affect SUS. Otherwise, look for light
    N-NE surface winds to back more N-NW by Thursday. A period or two
    of very light rain should affect COU later this afternoon and this
    evening, and could affect STL metro sites mainly this evening and
    have added in VCSH to primarily account for.
    SPECIFICS FOR KSTL: Clump of stratocumulus clouds with MVFR CIGs
    just NE of the terminal currently and should affect the terminal
    early this afternoon. Otherwise, VFR and mainly dry. A period of
    very light rain could affect the terminal this evening but is not
    expected to result in wet runways at this time due to the
    anticipated very light intensity.
