Area Forecast Discussion...Updated Aviation
National Weather Service Saint Louis MO
600 AM CDT Sat Jun 26 2021

.SHORT TERM...  (Through Late Sunday Afternoon)
Issued at 338 AM CDT Sat Jun 26 2021

One area of showers and a few storms was moving eastward through
northeast and central MO into west central IL with another area of
showers and storms over western MO which will move eastward into
our forecast area early this morning exacerbating the ongoing
flooding from recent heavy rainfall the past couple of days. This
current convection should weaken later this morning, but at least
scattered showers and storms will initiate by late afternoon into
the early evening hours along outflow boundaries from the early
morning convection and ahead of MCVs generated from ongoing and
recent MCS activity. A cold front currently extending from a
surface low over southwestern IA southwest into the OK Panhandle
will also shift southeastward into our forecast area tonight as it
gradually weakens with convection expected along and just ahead
of it in the moist and unstable atmosphere. The Flash Flood Watch
will continue through tonight for northeast and central MO and
west central IL, north and west of the city of St Louis due to
high precipitable water and deep warm layer cloud depths leading
to efficient rainfall production from showers/storms today and
tonight. Many areas, particularly in central MO have already had
record rainfall totals, and additional heavy rainfall will lead
to renewed flash flooding. A few storms this afternoon and this
evening may also produce damaging wind gusts and possibly also
hail. High temperatures today and Sunday will be trending a little
cooler. The warmest highs will likely be across parts of southeast
MO and southwest IL where less cloud cover and precipitation is
expected.

GKS

.LONG TERM...  (Sunday Night through Friday)
Issued at 338 AM CDT Sat Jun 26 2021

The active wet pattern will continue next week with southwest
flow shortwaves continuing to move through our area ahead of the
positively tilted upper level trough extending from the Northern
Plains southwest into CO and NM. The trend though may be a
lessening of coverage of convection by Tuesday as the upper level
ridge centered over the Mid-Atlantic region retrogrades into MO,
and the nocturnal low level jet is not as strong as the 850 mb
ridge over the eastern US retrogrades as well into southern IL and
southeastern MO. The temperatures will be trending cooler by
Friday as the deterministic models and ensemble guidance deepen an
upper level trough over the Great Lakes region sending a cold
front southward through our forecast area Thursday afternoon and
night. Temperatures by Friday should be below normal across the
entire area.

.AVIATION...  (For the 12z TAFs through 12z Sunday Morning)
Issued at 549 AM CDT Sat Jun 26 2021

Showers in the COU and JEF areas early this morning will move
into UIN and the St Louis metro area around 12-13Z Saturday
before dissipating. There will be a break in the convection by
late this morning, but the atmosphere will destabilize again with
more showers and storms for the afternoon and evening hours. The
prevailing cloud ceiling will be mainly in the MVFR category in
UIN, COU and JEF this morning, then improve to prevailing VFR
conditions in the early afternoon, and drop back into the MVFR
category late tonight. In the St Louis metro area it will be VFR
outside of showers/storms. The wind will be mainly south-
southwesterly through the period, except variable near storms.

SPECIFICS FOR KSTL: Showers in the COU and JEF areas early this
morning will move into STL around 12-13Z Saturday before
dissipating. There will be a break in the convection by late this
morning, but the atmosphere will destabilize again with more
showers and storms for the afternoon and evening hours.
It will be mainly VFR outside of showers/storms. The wind will be
mainly south-southwesterly through the period, except variable
near storms.
