.DISCUSSION...
Issued at 157 PM CDT Thu Jun 26 2025

Surface observations this afternoon depict a weak area of low
pressure across eastern Nebraska, with a weakening cold front
extending southwest into central Kansas. Satellite observations are
showing several bands of increasingly agitated cumulus ahead of and
parallel to the front. Given a moist and mostly uncapped airmass,
continued heating over the next hour or two should allow scattered
thunderstorms to develop. Forcing does remain quite weak though,
keeping confidence on the low end with regard to exact timing and
coverage of convection. Regardless, the environment continues to be
a very typical summer-time setup. Effective shear is weak, at less
than 15 kts, instability is moderate (2000-2500 J/kg), and moisture
content is high (PWAT 1.8-2.0"). Damaging winds with gusts up to
around 60 mph will be the main severe hazard, though some small hail
could occur with initial updrafts. Otherwise, as storms grow
upscale, there could be some isolated areas that pick up a quick few
inches of rain with a low-end flash flood risk. Generally though,
the more scattered nature of convection and a slow but steady
eastward progression will keep accumulations for most places around
or below one inch. Some places in north-central KS likely won`t see
anything. At any rate, any heavier storms will tend to clear east-
central KS by late evening, though a few weaker showers may linger
overnight.

Whatever weak boundary that still exists by tomorrow will lift back
north of the area as a broad zonal jet stream reestablishes itself
over the Northern Plains. This will keep warm and humid conditions
in place through the weekend. Highs climb into the 90s, lows stay in
the 70s, with heat indices approaching 100. Given a continued moist
airmass with only very weak CIN, can`t rule out an isolated shower
or storm across much of the weekend. However without any front or
upper shortwave to encourage ascent, most places will remain dry
through Sunday afternoon.

By Sunday evening and overnight, a front will push southeast across
the area as an upper trough begins to amplify over the Great Lakes.
This will increase shower/storm chances area-wide. Behind the front,
slightly cooler and drier air will work in, with dewpoints dropping
into the low/mid 60s by Tuesday afternoon. High temperatures look to
be near seasonal averages, in the upper 80s, with low temperatures
in the mid 60s slightly below average. Precipitation chances look
lower into mid-week behind the front, though in a typical summer
pattern like this it is difficult to discount PoPs altogether this
far out.

Issued at 1229 PM CDT Thu Jun 26 2025

Confidence is low on the exact timing and coverage of
scattered thunderstorms that will develop this afternoon and
evening, so have just left a Prob30 group at the main TAF sites. Any
storms should move east of KTOP/KFOE by mid to late evening though.
Ceilings remain VFR, with this afternoon`s gustier south winds
weakening this evening.
