Area Forecast Discussion...Updated Aviation
National Weather Service Saint Louis MO
1155 PM CDT MON JUN 13 2016

.UPDATE...
Issued at 928 PM CDT Mon Jun 13 2016

Most of the showers/storms have shifted northeastward into west
central and southwest IL this evening, extending from just east
of PPQ to just northeast of SLO. Most of this activity should
shift northeast of our forecast area by midnight. Could not rule
out isolated showers/storms late tonight, but it appears that the
latest HRRR model runs have a little too much late night
convection. With at least partial clearing and recent rainfall
there may be some patchy, short lived ground type fog late
tonight. Warm and muggy conditions again tonight with a weak
southerly low level flow and high surface dew points.

GKS

&&

.SHORT TERM... (Through Tuesday)
Issued at 359 PM CDT Mon Jun 13 2016

(Tonight)

Isolated to widely scattered showers and thunderstorms are
expected to drift northeastward and slowly weaken this evening.
Expect most of the late evening and overnight hours to be dry
(similar to the past couple of nights) though activity may linger
a bit longer due to some semblance of weak low-level warm/moist
advection. Temperatures will be similar to the past couple of
nights as well with much warmer conditions than normal for mid
June. Lows in the 70s for nearly everyone with the exception of
eastern Ozarks which should dip down into at least the upper 60s.

(Tuesday)

Unclear picture for tomorrow but in general should be less
coverage of showers/storms as mid/upper level ridge rebuilds
slightly into the mid-Mississippi Valley. Maintained some low
PoPs for some areas mainly for continuity sake. Will be an
unstable atmosphere with only small capping...but little to
nothing to really focus any convection as weak warm front should
be northeast of CWA. In addition...that boundary across the CWA
today is fairly diffuse already and so far this afternoon has
failed to produce much in the way of convective coverage. Main
story for tomorrow will be the heat and humidity. Raised high
temperatures a degree or two on Tuesday due to less expected
cloud cover and chances of storms. In addition...dewpoints will
be up a couple of degrees compared to this afternoon which will
combine with highs in the low to mid 90s to produce max heat index
values of 100-105 in some locations.

Gosselin

.LONG TERM...  (Tuesday Night through Next Monday)
Issued at 359 PM CDT Mon Jun 13 2016

A shortwave moving through the plains will bring a chance of
SHRA/TSRA to the region on Tuesday night. Forecast instability
and shear parameters are sufficient to support organized severe
wx, although the chances of severe wx appear to be higher farther
west of the CWA.

13/12z runs of the GFS/ECMWF/GEM remain similar to yesterday. The
aforementioned shortwave plows into the upper ridge and then
tracks southeastward through the Great Lakes towards the east
coast. A slight westward shift was noted in the track of the
mid/upper low compared to ydy's runs, and the 13/12z GFS output
at 00z Thu now begins to resemble its previous solution which
involved a cutoff low retrograding through the Ohio Valley towards
AR/OK. The inter- and intra-model disagreement-- whether, when,
and where the shortwave becomes cut off from the prevailing flow
near or downstream of the ridge axis-- appears to be caused by
slight shifts in both the track of the shortwave and the position
of the upper ridge axis. These small shifts lead to slightly
different solutions which make a big difference in the fcst temps
and precip chcs for MO/IL.

Following the solutions depicted by the current model suite,
the central CONUS ridge builds into Canada during the middle of
the week. The aforementioned shortwave which moves through the
Great Lakes will also drape a boundary across the region. High
pressure building into the Great Lakes behind the departing low
pressure system will push cooler and drier air into the region,
acting to sharpen the boundary and push it farther to the west.
Meanwhile, the mid/upper ridge continues to build and eventually
spans nearly coast to coast by 12z Sun, although it flattens in
response to a series of disturbances moving through Canada. This
means that warm and humid conditions will continue through at
least Wed/Thu until the back-door cold front moves through on
Friday, bringing a drier air mass into the region for next
weekend.

With warm and humid conditions expected to persist for most of
the week, attention then turns to the potential for heat
headlines. Heat Advisories may be issued for either 1) max heat
index of 105+ F on a single day, or 2) max heat index of 100+ F
for 4+ days. There are a handful of grid points with calculated
heat index values of 105 on Tue and Wed, however these values are
not widespread enough over any single county to warrant a Heat
Advisory. Likewise, there are many locations which may reach 100+
F for three of the four days between today and Thursday (a
different set of 3 days depending on location). No headlines will
be issued with the afternoon forecast package.

.AVIATION...  (For the 06z TAFs through 06z Tuesday Night)
Issued at 1142 PM CDT Mon Jun 13 2016

A period of radiational fog is possible overnight from 08-12z given
the light winds and current small temperature/dewpoint spreads,
reducing the visibility to primarily 3-5sm. Otherwise VFR flight
conditions are expected through much of the period. Present
indications are there will little to no diurnal convection on
Tuesday and the best threat of any organized showers and
thunderstorms will be late Tuesday night, beyond the valid TAF
period.

Specifics for KSTL:

A period of radiational fog is possible overnight from 09-12z
given the light winds and current small temperature/dewpoint
spreads, reducing the visibility to 5-6sm. Otherwise VFR flight
conditions are expected through much of the period. Present
indications are there will little to no diurnal convection on
Tuesday and the best threat of any organized showers and
thunderstorms will be well overnight Tuesday night into early
Wednesday morning. This would be near the end of the valid TAF
period and given the uncertainty I have not included in this
forecast issuance.
