.DISCUSSION...
Issued at 245 PM CDT Sun Jul 7 2024

Abbreviated discussion today due to ongoing convection.

Clusters of thunderstorms developing in very weakly capped
environment mainly along and south of a line from Kansas City to
Kirksville.  This area is located in the right rear quadrant of a
jet streak lifting off to the northeast.  A second jet streak is
expected to develop across central into southern Missouri this
evening, with upper level divergence mainly focused across central
Missouri.  The net result will be a south and eastward trend to the
convection with time.  Wind shear generally remains weak (> 30 knots
effective shear) so storms by and large should remain sub-severe.
Mean storm motion is around 25 knots, but training of storms within
environment of 1.5+" precipitable water could lead to locally heavy
rainfall.

Expect a bulk of the region to remain dry on Monday as weak high
pressure noses into the region from the northern plains.  The
remnants of Beryl are trending farther west with each model run.
Given this trend, have increase pops Monday night across central
Missouri.  With the tropical connection, will need to keep an eye on
the potential for locally heavy rainfall.

Developing upper level ridge across the west expands eastward
throughout the week leading to a warming trend.  With that said,
there are a series of ridge riders that are expected to move through
in the mean flow, potentially serving as focusing mechanisms for
thunderstorms.

.AVIATION /00Z TAFS THROUGH 00Z MONDAY/...
Issued at 610 PM CDT Sun Jul 7 2024

Lingering clouds around all TAF sites is expected to persist
into tomorrow morning, and are not expected to fall below VFR
overnight. Tomorrow morning, guidance has hinted at the
introduction of MVFR ceilings across all TAF sites, but the more
notable thing is a wind shift out of the west/northwest with a
passing cold front. So, keeping ceilings at VFR while
demonstrating the wind shift at around 15z tomorrow. Else, the
forecast will remain quiet, as any notable precipitation remains
off towards the east.
