.DISCUSSION...
Issued at 1200 AM CDT Tue Sep 8 2026

WV imagery indicates a southwest flow aloft prevailing across
the Western High Plains. Near the surface, a weak lee side
trough of low pressure remains anchored in eastern Colorado.

Hot/dry conditions will persist through late afternoon before
minimal thunderstorm chances (30-50%) return this evening as the
SREF indicates a closed upper low lifting northeast across the
high plains of eastern Montana, helping nudge an anchored
attendant lee side trough axis across extreme eastern Colorado
into west central Kansas by early evening. Prevailing
southerlies will help reinforce pooled moisture ahead of the
trough axis with surface dewpoints holding in the mid/upper
50s(F) to near 60F, providing sufficient instability with an
axis of MUCAPE values in excess of 1500 to 2000 J/kg in vicinity
of the trough axis. Despite marginal dynamic support aloft,
diurnally driven thunderstorm development is expected as H5 vort
maxima eject northeast out of the Southern Rockies, interacting
with the aforementioned trough axis/weak frontal boundary. The
best chance for rainfall will be across west central Kansas into
extreme southwest Kansas as suggested by most CAMs and where
the HREF shows a 20 to 40% probability of 6-hr QPF exceeding 0.1
of an inch by late Tuesday evening. Focus for thunderstorm
chances (50-70%) shift farther southeast Wednesday with a weak
frontal boundary projected to push slowly through the remainder
of southwest Kansas into south central Kansas by late afternoon.

Unseasonably hot temperatures continue today as prevailing
southerlies reinforce the much warmer air mass across the area
with H85 temperatures ranging from the upper 20s(C) in central
Kansas to a little above 30C in extreme southwest Kansas near
the Colorado line. Look for highs up into the lower/mid 90s(F)
behind the advancing trough axis in west central Kansas where
the latest HREF indicates a better than a 90% probability of
temperatures exceeding 90F but only a 50-70% probability of
topping 95F. Hotter temperatures are likely in south central
Kansas where HREF paints a 70-90% probability of highs nudging
above 100F. The run of temperatures climbing above the century
mark ends for much of the area Wednesday in wake of a weak cold
front pushing farther south into the Texas Panhandle and western
Oklahoma, dropping H85 temperatures below 25C across southwest
Kansas into south central Kansas to even near 20C in central
Kansas. More seasonal temperatures are likely in west central
Kansas to parts of central and extreme southwest Kansas where
there is only a 20-40% probability of temperatures exceeding 85F
to mainly the 90s(F) farther southeast into south central
Kansas.

.AVIATION /12Z TAFS THROUGH 12Z WEDNESDAY/...
Issued at 415 AM CDT Tue Sep 8 2026

VFR will prevail once again for this TAF period, with increasing
mid/high clouds after 00z Wed. After 15z Tue, southwest winds
will increase at all airports, gusting 25-27 kts. Winds will
decrease some around 00z Wed, and back more southerly. Any
thunderstorm development this period is expected to focus along
an EHA-GCK-HYS line, 00-03z Wed, close enough to include a
VCTS/CB mention at GCK/HYS. Kept DDC/LBL TAFs dry this update.
