.DISCUSSION...
Issued at 335 AM CDT Fri Jul 11 2025

Showers and storms continued across the area early this morning
as a shortwave trough continued to push through with a surface
boundary stalled across southern IA and into southeast NE and
west-central KS and surface low along the central NE/KS border.
Expect some lingering showers and perhaps a few isolated storms
this morning as the surface low continues to push east toward
the NE/KS/IA/MO border region, though they should generally be
in a dissipating stage. However, by this afternoon we should see
some redevelopment along the surface boundary, though latest
guidance suggests it should be just southeast of our forecast
area. Still, it`s worth keeping an eye on, especially with
2000-3000+ J/kg of SBCAPE per HREF guidance and potential for a
few stronger to severe storms, though weak deep layer shear
should somewhat limit storm organization if we manage to get
something to develop in our area. The main threats would be
damaging winds and some hail. The good news is that if we do get
any heavier precipitation, most of it should fall south of
where we saw the heaviest rain overnight, so the overall
flooding risk should be on the lower side.

Then as we head into the late evening and overnight hours, a
surface cold front currently stretching northeast to southwest
across ND and into MT and WY will push into the area and bring
some additional 20- 30% chances for rain. Latest CAMs suggest
coverage in our area could be somewhat limited with dissipating
trends as the front pushes southeast.

We should dry out Saturday morning with mid-level height rises
and surface ridging sliding through. This should lead to a
pretty nice day with highs mostly in the lower to mid 80s and
fairly "manageable" humidity, with dewpoints in the upper 50s to
lower 60s. We`ll rise back into the mid 80s to lower 90s on
Sunday as southerly flow returns on the back side of departing
high pressure. Guidance suggests some shortwave energy passes by
both just north and just south, but good agreement that we stay
dry. The warming trend will continue into Monday with
persistent southerly flow and highs in the 90s for most.

Active weather looks like it could return by Tuesday as a cold
front starts to approach from the north and some shortwave
energy slides by to our south. Still some spread in frontal
passage timing with various ensemble members pushing the front
through our area by Wednesday morning and others holding off
until Wednesday night. Guidance is in decent agreement that a
shortwave will then follow behind the front at some point and
give us a another shot at rain. Severe weather chances currently
appear to be on the lower side with strongest deep layer shear
remaining well to our north. However, depending on timing of the
front/wave, we could have quite a bit of instability in place
to yield some isolated severe storms. For what it`s worth,
various machine learning severe weather probabilities keep our
chances below 5%. Otherwise, temperatures behind the front
should be pretty comfortable, with highs in the mid 70s to mid
80s for at least a couple days.

.AVIATION /06Z TAFS THROUGH 06Z SATURDAY/...
Issued at 1145 PM CDT Thu Jul 10 2025

Strongest of thunderstorms have pushed east into western Iowa
with SHRA and -TSRA expected to linger through about 09Z at KLNK
and KOMA. Have added some BR to KOFK from 10Z to 14Z. Currently
have visibility remaining in VFR category (5 miles) but that may
certainly dip lower than that as cigs dip into MVFR category
through about 17Z.

Friday afternoon brings another opportunity for showers and
thunderstorms, but confidence in their timing and location is
too low to include in TAF issuance at this time.
