.DISCUSSION...
Issued at 122 PM CDT Wed Sep 2 2026

The main change today was the issuance of a Heat Advisory for
the southeast part of the forecast area (Stockton, KS to York,
NE) for today through Friday. Afternoon heat index values may
approach 105 degrees in some areas, and overnight lows will be
near record warmth (mid 70s). Rain chances remain very low
through Thursday, although a rogue shower or storm cannot be
ruled out late tonight into Thursday morning (5% chance).

The heat potential for Saturday is a bit more uncertain,
because a few showers/thunderstorms return to the forecast late
Friday night. Lingering cloud cover COULD keep temperatures a
bit cooler on Saturday, but if these don`t materialize then it
is possible that the Heat Advisory will be extended.

Low chances for thunderstorms continue through the Holiday
weekend as a series of upper disturbances are ejected from an
upper low over the Pacific NW. Timing will generally favor the
overnight hours, but confidence in exact details remains low at
this range. The aforementioned upper low will weaken the upper
ridge that has been responsible for the recent round of heat.
This will result in slightly cooler (but still above-normal)
temperatures through the middle of next week.

.AVIATION /06Z TAFS THROUGH 06Z FRIDAY/...
Issued at 1218 AM CDT Thu Sep 3 2026

For KGRI/KEAR Airports:

VFR conditions are expected through the TAF period. LLWS is
expected through 14Z. Consistent southerly winds around 12kts will
be present through the afternoon hours before weakening
slightly after sunset. Late in the TAF period a slight increase
in winds will occur as a low level jet develops. As the low
level jet kicks in, potential for LLWS will return, but
confidence is low at this time.
