.DISCUSSION...
Issued at 331 AM CDT Fri Apr 11 2025

A predominantly quiet and pleasant 7+ day forecast ahead with
near to above normal temperatures and a couple precipitation
opportunities, though at least one of them are trending drier.
But before we get into those details...

Shortwave trough responsible for widely scattered showers and
evaporatively enhanced gusty winds has shifted SE/away within the
larger NW upper level flow. Hot on its heels is another
shortwave trough, currently over Iowa and showing up nicely on
WV imagery. Unlike shortwave that moved through during daytime
Thursday, nocturnal timing of this wave and poor lapse rates
within the profile result in nil instability. Expect primarily
low to mid-level cloud cover to result near and east of Highway
65 through morning, dissipating during the afternoon. Shortwave
will also help suppress temperatures a few degrees over
yesterday as it ushers in 850mb temps approaching 0 deg C in
conjunction with light northerly surface winds and surface high
pressure building in. This will likely result in temperatures
near to a few degrees below normal in the mid-upper 50s (east)
to mid-upper 60s (west). Generally a pleasant spring day,
especially as cloud cover dissipates.

Western CONUS ridge begins to build into the Plains/central CONUS
Friday and through the weekend, but its effect will not be felt
locally until the weekend. As surface high departures Friday
overnight, southerly winds return, beginning a two-day warming
period. Developing surface low pressure over Colorado Front
Range will tighten surface gradients and push southerly wind
gusts into the 20s if not lower 30s mph, primarily over NW
Missouri and areas westward into Kansas Saturday. Surface low
moves off of the Front Range late Saturday in response to
approaching northern stream shortwave trough, shifting winds
more southwesterly by Sunday and peak wind gusts in the 20s to
mid 30s mph eastward across Missouri. Coupled with rising 850mb
temps through the weekend, into the teen deg C by Sunday, high
temperatures will jump around 10 deg F each day... mainly 70s
Saturday and up to the mid 80s Sunday.

The warmup will short lived though as a cold front associated with
the northern stream shortwave trough and its surface reflection
pushes across Missouri late Sunday into Monday, dropping highs
back towards normal in the 60s. Flagship synoptic models and
their ensembles continue to trend drier with this frontal
passage. Between GFS/Euro ensembles, only about 20% of members
show any precipitation with frontal passage limited by dry air
in place and inability to overcome strong capping inversion.
Ribbon of mid-level moisture is present, but that alone appears
unlikely to result in precipitation reaching the ground with no
available instability dry air to overcome. As the parent
shortwave trough sweeps into the Great Lakes Region, upper level
ridging gets squashed and a reinforcing northern shortwave
turns flow northwesterly by Tuesday and through the remainder of
the forecast.

Surface high streaming in Tuesday keeps highs near normal and
conditions quiet and clear into Wednesday before next, and
best, opportunity for showers/thunder moves into the area. Fair
degree of spread between synoptic guidance and ensembles when it
comes to both strength and timing/evolution of a northern
stream shortwave diving out of Canadian Plains, resulting in
fairly broad low to moderate (20% to 50%) PoPs from Wednesday
through Thursday night. Inevitably, precipitation will not be
present that entire time, but highlights the differences among
solutions. Prevailing solution and highest period of PoPs
(40-50%) results Wednesday night/overnight with moisture return
and LLJ. Uncertainty is also highlighted when looking at max
temp spreads increasing to 12 to 16 deg F by Thursday and
Friday.

.AVIATION /18Z TAFS THROUGH 18Z SATURDAY/...
Issued at 1226 PM CDT Fri Apr 11 2025

VFR conditions mainly expected for the duration of the TAF period.
An MVFR cloud deck moving in from the north should stay just to
the east of the terminals, however brief periods of MVFR
conditions are possible through the day. This cloud deck is
anticipated to begin dissipating this evening. Winds start the
TAF period out of the north and are expected to shift to the
south by tomorrow morning. Wind gusts up to 20-25 mph
anticipated tomorrow afternoon.
