.SHORT TERM /THROUGH SATURDAY/...
Issued at 443 AM CDT Fri Jun 26 2026

A low pressure system will continue to move across the region today.
Scattered showers and a few storms will be possible through the day
as a result. Cooler air will filter in from the west as this system
pushes east. Any stronger storms are expected to remain to the south
of the CWA, given that the front should be mostly through the region
in the late afternoon.

Temperatures will steadily warm beginning Saturday as ridging builds
aloft. Highs are expected to be in the mid-to-upper 80s on Saturday.
In the afternoon, the stalled front will drift north as a warm
front, which will allow for increased CAPE and moisture into the
region. Additionally, some vorticity and a weakening shortwave will
bring lift. Scattered showers and storms will be possible on
Saturday afternoon and evening. Looking into the environment, we
will see steep lapse rates, 30-35kts of 0-6km shear, plenty of
uninhibited SBCAPE. This will warrant a risk of strong to severe
storms, mainly for wind and hail.

.LONG TERM /SATURDAY NIGHT THROUGH THURSDAY/...
Issued at 443 AM CDT Fri Jun 26 2026

On Sunday and through most of next week, impressive ridging will
build over the central and eastern CONUS. Higher heights will
increase temperatures each day. High pressure at the surface, will
help to keep conditions dry. Enhanced southwesterly flow will
increase dew points, leading to hot and muggy conditions. NBM and
LREF ensemble probabilities show 60-90% chance of exceeding 95F most
of next week. Additionally, we will not see much recovery overnight,
as low temperatures are expected to be in the mid-to-upper 70s. Heat
advisories and warnings may be needed this next week.

&&

.AVIATION /06Z TAFS THROUGH 06Z SATURDAY/...
Issued at 1118 PM CDT Thu Jun 25 2026

A low pressure system will work over the region today, bringing
additional showers and storms this morning. Additionally, low
CIGs will build in during the remainder of the overnight period.
IFR CIGs are currently forecasted over most of the area and will
persist through mid-morning and into the early afternoon hours.
A band of precip between 8-11Z could bring CIGs to low-end IFR
or LIFR conditions. In the afternoon, CIGs will lift and thin
into the evening hours. Winds will back to the north in the
afternoon and the low pressure passes through the reigon.
