Area Forecast Discussion...Updated Aviation
National Weather Service Saint Louis MO
1242 PM CDT Wed Apr 5 2017

.SHORT TERM...  (Through Late Tonight)
Issued at 328 AM CDT Wed Apr 5 2017

Showers and thunderstorms are moving east across the area early this
morning.  Expect this line to continue to move east as the low level
jet veers and the best low level moisture convergence pushes east.
The deformation zone is set up currently from southern Iowa into
eastern Kansas will also move east across the CWA later this morning
and this afternoon.  The upper low which is causing all of this rain
will begin to lift out of the area by tonight, causing the showers
to end from west to east.

Temperatures will not rise much today with the clouds and the rain.
Temperatures will be nearly steady across northeast Missouri and
west central Illinois with not much more than a 5-10 degree rise
south of I-70. Temperatures will drop tonight behind a cold front
with lows in the upper 30s. It will be fairly blustery later today
and tonight as the surface low moves off to the the east and winds
pick up out of the north to northwest and turn gusty.

Britt

.LONG TERM...  (Thursday through Tuesday)
Issued at 328 AM CDT Wed Apr 5 2017

Deepening upper level and surface low will be over the OH Valley
region on Thursday.  Will continue to have wrap-around type low
level cloudiness on the backside of the storm system, along with
strong and gusty northwest winds due to the tight surface pressure
gradient.  Weak northwest flow shortwaves may be enough to generate
a few light showers or patchy light rain.  Both the ECMWF and GFS
models do have very light QPF across parts of our area.  Highs on
Thursday should be about 5 to 10 degrees below normal.  The coldest
temperatures will occur Thursday night due to good radiational
cooling as the surface ridge axis moves into western MO leading to a
clearing sky, diminishing surface winds, and surface dew points
dropping down into the middle to upper 20s.  Lows Thursday night may
be near the freezing mark in the colder locations.  There may also
be frost across parts of northeast, central and southeast MO where
the surface winds will become light by late Thursday night. Warmer
highs will occur on Friday mainly due to full solar insolation, then
pronounced warming for Saturday with above normal temperatures due
to upper level ridging over the region, and surface winds becoming
southerly on the backside of the surface ridge shifting east of the
area.  Highs by Sunday will be 10 to 15 degrees above normal.
Showers and thunderstorms will return Sunday night and Monday as an
upper level trough/low moves eastward into the northern Plains,
while the upper level ridge shifts east of our area.  A cold front
will move slowly southeastward through our forecast area Monday
through Tuesday. Showers and storms can be expected along and ahead
of this slow moving front as southwest flow shortwaves move over the
region.  The ECMWF model is initially a little slower with the
progression of precipitation into our forecast area Sunday night and
Monday due to its deeper upper level low and associated surface low
over the northern Plains.  The threat for convection should
eventually shift southeast of our forecast area by Tuesday afternoon
or evening.

.AVIATION...  (For the 18z TAFs through 18z Thursday Afternoon)
Issued at 1242 PM CDT Wed Apr 5 2017

Main TAF concerns will be shower/storm trends today, low cigs, and
gusty WNW winds overnight. An area of low pressure currently
centered over eastern MO will continue to push east this afternoon
into this evening. As it does, showers and thunderstorms will
increase in coverage, with the best potential for any
thunderstorms in the St. Louis metro sites through late this
afternoon. While MVFR/low-end VFR conditions will be possible at
the St. Louis sites early this afternoon, all sites should go MVFR
(or IFR at COU/UIN) by late this afternoon into the overnight
hours. As the low pushes east, gusty WNW winds will commence late
this afternoon into this evening, with gusts of 30-35 knots
posisble. Drier air and VFR conditions will slowly filter in by
Thursday morning, but the gusty WNW winds will continue through
the day on Thursday.

SPECIFICS FOR KSTL:
Showers with a few thunderstorms are expected this afternoon,
before activity tapers off late this evening into the early
overnight hours. Cigs will likely bounce between MVFR/VFR for the
next few hours before solidly going MVFR (perhaps even high-end
IFR) late this evening into the overnight hours behind a cold
front. Conditions should improve to VFR by Thursday morning, but
gusty WNW winds (gusts of 30-35 knots possible) will persist
overnight through the day on Thursday.
