.DISCUSSION...
Issued at 155 PM CDT Sat Jul 12 2025

Slow moving upper trough migrating through the southern plains this
afternoon, triggering several clusters of storms from Texas into
Oklahoma. Showers and storms as far north as central Kansas near a
secondary meandering front may impact portions of east central
Kansas (south of I-70) this afternoon and evening. Effective shear
is less than 20 kts while CAPE values average near 2000 J/KG.
Updrafts should overall not be severe with the exception of
lightning and brief, heavy rainfall.

This pattern persists until the upper trough exits on Sunday
afternoon with low chance pops kept in for areas near and south of
the I-35 corridor. Quasi zonal flow returns next week, featuring no
prominent waves impacting the region until perhaps the Thursday-
Friday period. Given the setup with environment largely uncapped
Monday-Wednesday, cannot rule an isolated storm or two in the late
afternoon Tuesday. The heat becomes more oppressive Tuesday and
Wednesday afternoons as heat indices range from 100 to 105 degrees.

Cluster ensemble analysis exhibits disparities on
the 500 mb heights for the northern stream trough pushing a cold
front through the central plains Thursday-Friday. When it does
occur, it may be the best chance for widespread rainfall in the
forecast.

Issued at 1238 AM CDT Sun Jul 13 2025

Showers have become a bit more numerous south of the terminals
in recent hours downstream of a weak upper trough. Can`t rule
out a stray shower at FOE and TOP through around 12Z but chances
look too low to mention. Light mainly northeast winds dominate
under some mid and high cloud with clearing conditions slowly
taking place through this forecast.
