At 17z a mix of IFR-MVFR flight conditions persist from kcou into
the St. Louis region, while VFR conditions prevailed across
northeast MO into west central Illinois. Northeast low level winds
advecting drier air should result in improving conditions this

redevelop along and south of a kcou-kstl line resulting in a mix
of IFR and MVFR flight conditions lasting through 14-15z Friday, with
improvement late Friday morning.

Specifics for kstl:

Northeast low level winds advecting drier air should result in
improving conditions this afternoon with ceiling heights rising and
VFR by middle afternoon. Overnight however it appears that
stratus/fog will redevelop resulting in MVFR flight conditions
lasting through 14-15z Friday, with improvement late Friday morning.
