.DISCUSSION...
Issued at 205 PM CDT Fri Jul 24 2026

Shortwave across west central MO as of 18Z is expected to work east
this afternoon and evening allowing upper level ridge across the
southwestern US to expand north and east. Upper level subsidence
behind departing shortwave should lead to a reduction in storm
potential late this afternoon into this evening, but CAMs have
offered a variety of solutions of isolated shower/storm activity,
largely focused south of I-70 through the evening hours.  Moist
adiabatic lapse rates aloft keep instability limited, but partial
clearing across eastern KS into west central Missouri may allow for
a late afternoon/evening pop up storm.  Weak shear should keep
anything that develops subsevere.

Weak low level jet is expected build heat and humidity northward
tonight strengthening capping inversion across the region and
temperatures remaining in the 70s overnight. Heat is expected to
build further on Saturday, and have issued a heat advisory along and
south of I-70 Saturday. Heat is expected to build further Sunday
into Monday, and have issued a heat advisory area wide through
Monday evening. Models suggest there may be a few ridge ridging
short waves, one that may result in an MCS Sunday night into Monday
morning across the Upper Midwest. Through collaboration, have sided
with the idea that there will be limiting lingering impacts across
the region on Monday.

A cold front may try to build south across the region Monday night
into Tuesday.  South of the front, there is the potential for the
need for additional heat headlines, but the timing of the front is
unclear at this point.

Longwave pattern remains late into the week with upper ridge across
the western CONUS, with shortwaves continuing along the northern
periphery of the ridge.  With little agreement on timing of the
waves, left the model blend as is with above normal temperatures
and periodic low chances of precipitation.

.AVIATION /00Z TAFS THROUGH 00Z SUNDAY/...
Issued at 615 PM CDT Fri Jul 24 2026

MVFR to IFR conditions will likely (>80%) transition to VFR
conditions during the overnight hours to early morning hours on
Saturday. There is uncertainty in the timing of this but for it
looks like in the 05Z to 10Z time frame. One other caveat, there
is a small chance (<15%) for fog to develop in the area of the
terminals. Better chances reside in northern MO and far
northeastern KS. But we`ll need to monitor trends to see if this
potential increases further south.
