.LONG TERM:  (Tonight through Sunday)
Issued at 223 AM CDT Mon Sep 29 2014

Western CONUS longwave trof will move east into the Midwest by
midweek with a good chance of rain in the offing for the entire
CWA begining as early as Wednesday afternoon across central
Missouri and exiting southern Illinois by early Friday morning.

Model guidance in pretty good agreement that best chances of
precipitation will be Wednesday night through Thursday night. A
strengthening low level jet will transport quality moisture into
the region Wednesday night and precipitation should become
widespread across the northwestern half of the CWA where a series
of weak disturbances will eject northeast out of the base of the
longwave trof. By Thursday the cold front will be knocking on our
doorstep and this, along with the main trof axis will contribute
to additional showers and thunderstorms through early Friday
morning.

Cooler air expected in the wake of the front, with below normal
temperatures forecast for Friday and Saturday, before returning to
normal on Sunday.

.AVIATION:  (For the 06z TAFs through 06z Monday Night)
Issued at 1138 PM CDT Sun Sep 28 2014

VFR flight conditions will continue to prevail across most of the
area tonight. Still expecting river valley fog much like the last
couple of nights which will locally reduce visibility to MVFR and
occasionally IFR. Any fog that develops will dissipate quickly
after sunrise and VFR conditions will prevail through Monday.

Specifics for KSTL:

VFR flight conditions are expected to continue at Lambert.
