Area Forecast Discussion...Updated Aviation
National Weather Service Saint Louis MO
1229 AM CDT Wed Oct 10 2018

.SHORT TERM...  (Through Late Wednesday Afternoon)
Issued at 336 PM CDT Tue Oct 9 2018

Main concern in the short term continues to be the strong cold front
that will slide through the region late tonight through Wednesday.

Latest HRRR is beginning to come into better agreement with what is
actually happening over region as of 20z. Ahead of system, scattered
showers and thunderstorms are developing in a moderately unstable
environment with surface based CAPES in excess of 1500 J/kg and
effective bulk shear 30+ kts over portions of central/northeast
Missouri as of 20z. This initial round of activity is more diurnally
driven so should see showers and storms diminish a bit towards
sunset. However, the break in activity will not be long as more
significant storms develop along prefrontal trof over central
Missouri after 02z Wednesday and track east through forecast area
during the late evening and early morning hours. There will be
plenty of instability and shear late into the evening for a few
strong to severe thunderstorms over portions of central/northeast
Missouri as well as west central Illinois. SPC has kept this area in
a slight risk with the main threat being damaging winds, though
isolated tornadoes and large hail are possible.

Then another round of activity to fire along main cold front after
08z Wednesday over western Missouri and track eastward through
forecast area during the day on Wednesday.

With progressive nature of system, rainfall amounts will remain
below flash flood criteria, though could see between half an inch
and an inch of rainfall through Wednesday afternoon before system
exits region.

As for temperatures, another mild night tonight with lows only in
the mid to upper 60s. On Wednesday, highs will be in the upper 60s
to upper 70s, with steady or falling temperatures during the
afternoon hours most locations.

Byrd

.LONG TERM...  (Wednesday Night through Next Tuesday)
Issued at 336 PM CDT Tue Oct 9 2018

Strong surface ridge to build into region Wednesday night with
scattered showers exiting region. Ridge will usher in much colder
air with lows in the upper 30s to upper 40s Wednesday night. Highs
on Thursday will only be in the low 50s to low 60s, which are 10
to 15 degrees below normal for this time of year.

By Thursday night, even colder temperatures can be expected with
lows in the mid 30s to low 40s. This cold air combined with little
or no winds and clear skies could allow for the formation of patchy
frost across northern portions of forecast area. However, confidence
is low as a quick moving shortwave to approach region towards
daybreak on Friday, so should see increasing clouds. Left out
mention of patchy frost for now.

Upper level shortwave to slide through region on Friday undercutting
surface ridge. Even though moisture will be limited, isolated/
scattered showers will develop by midday and slide quickly east
through forecast area, exiting by early Friday evening.

Beyond that, better chances of rain will move into the region
Saturday evening and persist through Sunday night before exiting
Monday morning. Still some differences in timing, strength and
duration of the rain for the weekend as a southern stream shortwave
slides through region just south of forecast area Saturday night
through Sunday morning and a northern stream system slides through
region Sunday night. No major changes to ongoing forecast at this
time. Below normal temperatures to persist through remainder of
forecast period.

.AVIATION...  (For the 06z TAFs through 06z Wednesday Night)
Issued at 1211 AM CDT Wed Oct 10 2018

A line of showers with a few embedded thunderstorms continues to
move slowly east through central and northeast Missouri into east
central Missouri and west central Illinois. This slow progression
eastward is expected to continue through the rest of the night and
into Wednesday. Heavy showers embedded in the line will be capable
of intermittently dropping visibility and ceilings to IFR.
However, think flight conditions will generally stay MVFR with the
line of showers. Most guidance fills in low ceilings after 12Z
ahead of the cold front with heights down below 2000 feet. The
front will move through from east to west from around 15Z in
central Missouri to around 20-22Z. There should be a general
improvement to VFR during the afternoon after FROPA. Southerly
flow ahead of the front will turn sharply to the west after the
front passes.

SPECIFICS FOR KSTL:

The line of showers moving into east central Missouri will likely
be to the terminal by 08-09Z. There are a few embedded
thunderstorms which will be capable of reducing visibilities to
IFR levels, and ceilings could drop below 2000 feet in these
storms as well. More shower activity is expected in the morning
with ceilings dropping below 2000 feet ahead of the front. Latest
guidance has the cold front moving through the terminal between
18-19Z, and other than a stray shower that should be the end of
the precip. Ceilings should begin rising behind the front as well
and I expect VFR flight conditions by late afternoon or early
evening.
