.DISCUSSION...
Issued at 258 AM CDT Mon Aug 11 2025

Broad mid/upper level troughing is over the Plains with an
embedded shortwave in eastern CO moving into western KS today.
This mid/upper level forcing coupled with a stalled out front
and a strengthening LLJ is helping to propel and maintain an MCS
with two embedded MCVs coming out of CO and into western KS this
morning. With PWATs of 1.7 to 1.9 heavy downpours and flooding
remains possible. Models however, are really struggling with the
progression of this MCS which is resulting in a fairly low
confidence forecast going forward today. But, the latest HRRR
and ARW seem to be latching on to the ongoing convection and
could be the best solutions going forward right now. Given that
and that present environment, the parent MCS looks like it will
die before it gets to western MO while one or both of the MCVs
may barely survive into the daytime hours. Then this MCV could
encounter 1,500-2,000 J/kg of MUCAPE and about 20-30 kts of
0-6km bulk shear this afternoon which could re-strengthen the
MVC as it moves through the forecast area. PWATs remain high
today and so heavy downpours remain possible.

Tuesday the general trof pattern aloft continues to shift east
and with the stalled front still present, more showers and
storms are expected throughout the day (30-50% chance). Once the
front dissolves though and ridging starts to take its place,
things start to dry out by mid to late week along with warming
temperatures heading into the weekend. Heat indices are once
again pushing 100 degrees by the weekend.

Issued at 608 AM CDT Mon Aug 11 2025

Watching an extended band of storms approaching the terminals
from SE KS at this time. Another east west band current
affecting STJ...but deepest convection there east of the site.
Current thinking is that line of storms to the southwest will
survive to at least IXD and probably KMCI/KMKC. Could be some
brief lower cigs in the wake of that line. Then will watch for
additional development later this afternoon. Winds generally
will be from the south and southwest during the day and then
more variable tonight.
