AREA FORECAST DISCUSSION...UPDATED AVIATION
NATIONAL WEATHER SERVICE ST LOUIS MO
638 AM CDT Sun Sep 28 2014

.SHORT TERM:  (Through Late This Afternoon)
Issued at 243 AM CDT Sun Sep 28 2014

Upper low to our northwest will open into a wave as it passes
overhead today. Will see an increase in diurnal clouds due to
colder temperatures aloft and a few of the convective allowing
models are printing out some isolated showers/sprinkles across
parts of central Missouri and perhaps the eastern Ozarks. Have
added a chance of sprinkles to account for this chance. Otherwise,
continued mild conditions with highs in the lower to middle 80s.

.LONG TERM:  (Tonight through Saturday)
Issued at 243 AM CDT Sun Sep 28 2014

Forecast remains unchanged with the tranquil weather pattern
coming to an end by the later half of the work week. The upper level
trof across the western CONUS is still progged to edge east
bringing unsettled conditions to the CWA, with several periods of
showers and thunderstorms. Temperatures will remain mild ahead of
the front through Thursday night. Have stayed close to model
consensus for post frontal temperatures with highs in the 60s and
lows in the 40s.

.AVIATION:  (For the 12z TAFs through 12z Monday Morning)
Issued at 626 AM CDT Sun Sep 28 2014

Specifics for KCPS, KSUS: Radiation fog (enhanced invof nearby
rivers) was producing highly variable visibility readings at KSUS
and KCPS early this morning, with the reported visibility crossing
multiple flight categories in one fell swoop (e.g., 1SM to 10SM at
KCPS and 6SM to 1 3/4SM at KSUS). Similar to the last 2 mornings,
this variability should improve over the next 1 to 3 hours as the
fog begins to mix out. VFR conditions are expected for the rest of
the day.

Specifics for KSTL, KCOU, KUIN: VFR with light winds due to a
ridge of high pressure. Light rain sprinkles are possible at KCOU
after 18z as a weakening upper low moves overhead, but confidence
is too low to include in the TAF at this time.
