KEY MESSAGES

- Unseasonable warmth continues through the end of the week. A Heat Advisory has been issued for part of the area.

- Mostly dry through Friday. Off and on low chances (20-30%) for thunderstorms return late Friday night through the weekend.

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 /18Z TAFS THROUGH 18Z THURSDAY/

Issued at 1241 PM CDT Wed Sep 2 2026

For KGRI/KEAR Airports:

VFR conditions will prevail through the TAF period. Very low chances (~10%) for a rogue thunderstorm in the vicinity of KEAR and KGRI this evening into tonight, and thus have not mentioned these in the TAFs. The primary hazard for tonight will be LLWS of 45+ kts, with the shear layer beginning right around 700 ft. Shear will likely start off near 180 degrees and shift closer to 210 degrees overnight, before shutting down around 13z (8:00a CDT) Thursday morning. Surface winds will remain out of the S to SSW, except for a SSE shift from 00z (7:00p CDT) through 08z (3:00a CDT) tonight into Thursday morning. Surface gusts of 15-19 kts are expected, especially during the daytime. Confidence is lower in overnight gusts as surface inversion development will likely limit downward mixing of stronger winds from aloft.
