KEY MESSAGES

- Scattered t-storms arrive from the west this evening through tonight. A few could be severe in the 7pm to midnight timeframe (mainly northwest of a line from Cambridge to Albion). Wind is the primary threat. - One last round of heat is expected in our southeast on Tuesday before more seasonable temperatures return for the rest of the week. A Heat Advisory has been issued near/south of a line from Stockton, KS to Hebron, NE.

- Scattered showers and t-storms persist on Tuesday. Most of these will be non-severe, but an isolated strong to marginally severe storm is possible.

DISCUSSION

Issued at 215 PM CDT Mon Sep 7 2026

Relatively deep mixing is resulting in breezy south winds with gusts near 30 MPH across much of the area. Spotty gusts as high as 40 MPH cannot be ruled out through late afternoon.

Convection is expected to develop along a pre-frontal trough over western Nebraska this evening, potentially reaching Furnas/Gosper/Dawson counties by around 7pm. A few of these storms could be marginally severe through the evening, but intensity is expected to wane by midnight. The primary threat would be wind given the deep mixing and high cloud bases.

Scattered showers and thunderstorms persist through the overnight and into Tuesday morning as a cold front pushes in from the northwest. South of the front should remain mostly clear, allowing for one more day of heat index values near/over 105 degrees. A Heat Advisory was issued for areas that are most favored to remain south of the front into the afternoon, although there is some potential for this to "bust" if the frontal timing were to speed up. Fun fact: this is the latest Heat Advisory ever issued by NWS Hastings. Prior to this year, we had never issued a heat advisory in September, but there have been 4 days with Heat Advisories this September!

Most of the storms during the daytime should be non-severe, although CAMs hint at slightly more robust convection along the front late Tuesday afternoon into the evening. This would favor southeastern portions of the forecast area that are warmer and therefore more unstable.

Wednesday and Thursday trend drier with more seasonable temperatures (highs in the low 80s and lows in the upper 50s to low 60s). That said, some low PoPs (10-20%) persist over portions of Kansas. Above-normal temperatures are favored to return Friday, but another system will provide a cooldown and additional rain/t-storm chances for Saturday through next Monday.

AVIATION /18Z TAFS THROUGH 18Z TUESDAY/

Issued at 1157 AM CDT Mon Sep 7 2026

For KGRI/KEAR Airports:

Strong, southerly surface winds around 15-18kts, with gusts up to 25-30kts, will continue into the overnight hours. LLWS is expected tonight, as the low-level jet develops through the area. These low-level winds (around 1500ft) will start out SSE and veer to SW by 10Z tomorrow morning.

The main uncertainty with this forecast lies in the timing of a cold front through the area and any thunderstorms along it. Current model guidance depicts this cold front "stalling" just north of the area tomorrow morning, before progressing through the terminals at end of the period. However, exact frontal timing and location of this stall remains uncertain. Additionally, a band of thunderstorms are possible along this front after midnight, with activity near the terminals as early as 3Z (especially for KEAR). Current model guidance depicts this band to set up through central NE, with KEAR/KGRI on the southern periphery of this activity. However, the exact location of this band is uncertain, with a slight southern shift in location potentially causing more impacts for the terminals.
