.SHORT TERM...
(Tonight through Monday Night)
Issued at 1115 PM CDT Sat Sep 20 2025
Isolated showers and storms occurred Friday evening and again
Saturday evening. Continued weakening of the warm upper level
ridge and a series of impulses from the west will increase
coverage of scattered showers and storms for Sunday. Although the
coverage will peak in the afternoon and early evening, some
showers and storms may begin in the morning as the first impulse
arrives. As temps warm through the day, a few of the scattered storms
could produce heavy downpours, gusty winds over 40 mph, and
perhaps some small hail. Forecast soundings show DCAPE again
reaching around 1000 with precipitable water climbing from around
1.25" to over 1.50". Shear is minimal. The higher PW values may
result in issuance of a few flood advisories in areas where heavy
downpours linger. Localized rain over 2 inches could occur,
although around half of our coverage area will remain dry.
Coverage will trend up a little more for Monday as atmospheric
moisture deepens and more disturbances come our way. A couple of
strong storms with gusty winds will continue to be possible along
with pockets of local heavy downpours.
High temperatures Sunday and Monday will be a few degrees cooler
than recent days thanks to lower heights, more clouds, and higher
coverage of showers and storms.

.LONG TERM...
(Tuesday through next Sunday)
Issued at 1115 PM CDT Sat Sep 20 2025
A trend toward higher rain chances and lower temperatures will
occur through midweek. A series of disturbances in zonal flow
between a trough over the Great Lakes and a ridge over TX will
bring the increasingly unsettled conditions. Atmospheric moisture
will deepen through the period giving greater coverage of showers
and storms. Greatest coverage will occur in the afternoon hours,
but chances will be in the forecast other times as well.
Wednesday into Thursday, the Great Lakes trough will combine with
a wave coming out of the Rockies to produce a deep closed low just
to our west. This will help focus deep moisture and lift over our
area with rain becoming likely. Rainfall amounts Wednesday into
Thursday could total 2 to 3 inches in some spots, so local
flooding will be a concern.
Coverage and intensity of rain will taper down late week, but it
will still be showery with a good deal of cloud cover as the upper
low drifts slowly overhead. We can look forward to cooler, near
normal temperatures late week with lows mostly upper 50s and lower
60s and highs in the 70s to lower 80s.

(06Z TAFS)
Issued at 1220 AM CDT Sun Sep 21 2025
VFR conditions for most of the cycle, but we are expecting
isolated to scattered storms around the mid-state tomorrow. This
is enough to include PROB30s for all terminals for several hours
each. Will try to hone times with next issuance or amd if needed.
Winds will be light and south to southeast on Sunday.
