KEY MESSAGES

- Seasonably cool temps (60-70s), limited precip chances (mainly 10-30%), and lots of clouds expected to start the work week.

- Increasing storm chances mid-week, with unsettled weather likely continuing into next weekend.

DISCUSSION

Issued at 130 PM CDT Sun Sep 20 2026

Mostly cloudy skies, a bit of drizzle and cool temperatures lingered across the local area today. An upper level low across eastern Wyoming on Satellite is helping to trigger a few thunderstorms across the high plains - which if model data is correct, should mostly dissipate at they approach the area late this evening as they move into a more stable environment.

Overnight, a few storms could cross areas mainly north of I-80, closer to the center of the low, as it tracks east across the central plains. If realized, the environment remains unfavorable for strong or severe storms due to a lack of instability, and any storms should remain isolated and on the weaker side. Of secondary concern, there are some hints of fog development across the area to start the day Monday with the latest HRRR indicating some widely scattered dense fog. Given the light northeasterly winds and minimal T/Td spread, cannot rule out at least some patchy fog formation, and consequently added fog to the forecast to start the day Monday.

While some small pops remain in the forecast for Monday, most of the local area should remain dry behind the departing upper level low, with these mostly dry conditions likely prevailing through at least midday Wednesday, as weak ridging sets up across the local area ahead of the next more notable disturbance. While some small splotchy pops remain in the forecast at times late Monday through Wednesday afternoon, model signals for precip mid-week with this next disturbance have really ramped up over the past 24 hours, with most of ensemble members indicating a potentially very wet Wed/Thursday time period. While surface temperatures remain on the cooler side of climo and instability is on the lower side, could see some embedded thunderstorms Wednesday night through Thursday, with more showery and less widespread precip expected to end the week and continue into next weekend.

Overall, a seasonably cool and occasionally unsettled period is forecast to continue across the local area for much of the next 7-10 days, with lots of cloud cover and the potential for some morning fog at times.

AVIATION /00Z TAFS THROUGH 00Z TUESDAY/

Issued at 627 PM CDT Sun Sep 20 2026

For KGRI/KEAR Airports:

The primary aviation impact tor KEAR/KGRI over the next 24 hours will be the potential for Fog tonight as well as low (LIFT) ceilings. The deck of low-level stratus is unlikely to lift any further tonight with bases maintaining under at least MVFR classifications until Monday afternoon (after 18z, there is a 40-60% chance for VFR ceilings {cloud bases still 3,000-6,000ft} at KEAR and 20-30% chance for KGRI). The potential for IFR ceilings (80%+ chance) increase for KGRI after 3z and after 4z for KEAR. LIFR classifications are likely across much of the 8-15z period.

Beyond the low cloud ceilings, fog formation could begin between 7-10z with visibilities dropping as low as 1/2 to 2 miles between 11z and 14z. Fog lingering past 15z will be unlikely.

Though there are a mix of scattered thunderstorms and showers across western Nebraska this evening, it is uncertain how far east these storms will make it before dissipating (not a lot of model confidence). As result, the mention of a prevailing storm or shower was not included in the TAF at this time. A few brief showers may be possible across the night and through the first half of the day Monday.

Winds will remain mostly light and out of a northerly directions tonight. Gradually increasing winds Monday afternoon (up to 10-15kts) will coincide with northeast turning winds.
