KEY MESSAGES

- Isolated thunderstorms remain possible through the afternoon hours with a cluster of storms rolling off the high plains expected to impact the area overnight. Severe weather is unlikely.

- Seasonably cool weather expected Sunday onwards with highs in the 60s and 70s. (Normal high temperatures range from the mid 70s to low 80s across the local area)

- Off and on shower and thunderstorm chances remain in the forecast through the end of next week as west to southwesterly flow aloft continues across the plains through the period.

DISCUSSION

Issued at 236 PM CDT Sat Sep 19 2026

A line of showers and thunderstorms has developed across western portions of the area this afternoon. These showers and thunderstorms are expected to rapidly weaken and dissipate as they track eastward through early evening hours with a more robust line of showers and thunderstorms eventually developing to our southeast later this afternoon along yesterdays cold front. In general, the 18Z HRRR seems to have caught on to this initial line of showers and thunderstorms stretching from Dawson in to Furnas counties, and largely updated the pops for the next few hours to reflect this.

Later tonight, expect a cluster of showers and thunderstorms developing across the Rockies to move into the plains, bringing a better shot for some more widespread shower and thunderstorm activity overnight. Given limited instability and shear, this cluster should be weakening as it crosses the local area, but cannot completely rule out a stronger thunderstorm across our west initially, especially across areas west of Highway 183. Further east, thunderstorm coverage will diminish and only light rainfall accumulations are anticipated by Sunday morning.

After a seasonable day this afternoon, expect temperatures to be on the cooler side of climo Sunday afternoon, which will mark the start of a prolonged period of seasonal to seasonably cool temperatures across the region. At the same time, the flow aloft will fluctuate between westerly and southwesterly, which should allow multiple upper level disturbances to cross the local area through the period - bringing off and on chances for unsettled weather across the central plains. It certainly will not rain or storm across the entire area every day, but expect at least a chance for precipitation across the local area with each passing disturbance.

For KGRI/KEAR Airports:

MVFR CIGS will persist at both terminals through the afternoon hours with CIGS lowering during the late evening hours as an approaching area of showers and thunderstorms from the west spreads lower CIGS and the chance for -SHRAs and -TSRAs at both sites. Could see some lingering BR behind this complex of storms to start the day Sunday, with improving conditions (albeit with continued MVFR CIGS) expected by around 20/15Z.
