KEY MESSAGES

- The Areal Flood Warnings across portions of Hamilton, York, Clay, Filmore, Nuckolls and Thayer counties will remain in effect this evening and likely tonight as many areas, slow to drain, continue to have water-levels near and exceeding their stream/river banks.

- A few more isolated storms will be possible tonight (mainly across areas south to southeast of the Tri-cities area) and Sunday (mainly areas east of HWY-281). These storms should remain sub-severe and will be highly scattered in coverage.

- A severe storm or two can't be ruled out Monday evening/night. The best potential will be towards the west to southwest portion of the area.

- Temperatures will warm some Monday (mid 80s to lower 90s) and Tuesday (mid 90s to low 100s). A cold front passage on Wednesday should point highs more towards the 80s to lower 90s for the rest of the week.

- A few passing disturbances next week as well as uncertainty on exact timing keep precipitation chances in the forecast virtually each afternoon for at least a portion of the area.

DISCUSSION

Issued at 427 PM CDT Sat Jun 6 2026

Short Term...Today through Sunday.

Following some late night thunderstorms across a few mainly northern and eastern portions of the area, observed spots of minor flooding and full/overflowing stream/river beds prompt the need to continue the Areal Flood warnings across a few of our southeastern Nebraska counties (Hamilton, York, Clay, Filmore, Nuckolls and Thayer) until at least tonight. For more information regarding the ongoing flooding, please refer to the hydrology section below.

Today we find ourselves underneath split flow as broad ridging covers the Northern Plains with a shortwave trough centered across the Southern Plains. The disturbance down south will be expected to take a northeastward track up to the Midwest through the first part of the new week. Outer precipitation bands from this system may slide by a few southeastern portions of the area this evening and tonight. A few weak (non-severe) storms will likely pop up between 4- 10PM across a few portions of north central Kansas and southeast Nebraska (areas mainly south and east of the Tri-Citoes). As the coverage of precipitation is expected to be more of a "hit or miss" and highly scattered rather than widespread in coverage, PoPs for any given location remain on the weaker side (10-30% for the southeastern third of the area, mainly locations southeast of a line from Geneva, NE to Red Cloud, NE to Plainville, KS).

For Sunday, a few scattered showers and weak storms will disperse across the eastern portion of the area (mainly areas east of HWY- 281) with up to 30-50% PoPs hovering across the eastern fringes of the area through the afternoon hours. Otherwise, temperatures tonight will cool down to the low to mid 60s with light winds remaining out of the southeast. Overcast skies filling in across the overnight hours will begin to clear out across the later morning to later afternoon hours Sunday (clouds making up the outer cirrus shield of the southeast passing disturbance). Highs for sunday, despite the partial cloud coverage, should be able to return to the low to mid 80s Sunday afternoon.

Long Term...Monday and Beyond

A northwest located trough will gradually push out the Northern Plains ridge, later retuning the mid to upper level flow to southwesterlies by Monday. A quick passing shortwave disturbance on Monday may throw a few more scattered storms into the area (25-50%). The potential of severe weather could return to a limited (southwest) portion of the area Monday evening/night as increasing instability from warming temperatures could add some extra intensity to a few storms. The rest of the forecast period (through next Saturday) continues to bring at least a limited afternoon to nighttime pop up storm chance to at least a portion of the area. These daily chances come from increasing uncertainty on how the upper-level pattern will unfold (when a few minor disturbances embedded within the approaching trough will pass through the Region).

Temperatures will be heating up into the middle of the week as highs transition from the 80s on Monday to the 90s and low 100s on Tuesday and Wednesday (Heat indices possibly as high as 105 degrees). This warm up will best be assisted by clearing skies and steady southerly winds winding up Tuesday afternoon. A frontal passage on Wednesday should place a cap on the warming trend, though the 80s to low 90s look to be possible each day for the of the week.

For KGRI/KEAR Airports:

Winds will range from the southeast to south generally between 5 to 15 MPH. MVFR ceilings are expected at KGRI and possible at KEAR beginning around 06z and continuing until around 17z Sunday. Showers and an isolated thunderstorm are possible at KGRI Sunday morning (after 12z) into the afternoon hours. Confidence was too low to include at this time.

HYDROLOGY

Issued at 427 PM CDT Sat Jun 6 2026

Flood water across several of our counties will be slow to recede within the hardest hit areas. The flooding in some areas is expected to persist through tonight and possibly into Sunday morning.

The basins most likely to experience continued flooding into tonight include: West Fork of the Big Blue River (Downstream of Stockham) Beaver Creek (Giltner through York County) Lincoln Creek (Hamilton and York Counties) School Creek downstream of Sutton Turkey Creek in Fillmore County Little and Big Sandy Creek (Corner of Clay, Fillmore, Nuckolls, Thayer Counties)

Any additional rainfall this evening/tonight is expected to be isolated and non-impactful to our ongoing flooding.
