The episode as NWS LBF wrote it up.
Scattered thunderstorms developed over southwestern Nebraska during the mid afternoon hours of July 29th. Thunderstorms grew upscale over the next couple of hours, becoming widespread across the area by early evening. Heavy rain of 1 to 3 inches fell from Lincoln into Custer County, leading to flash flooding in the North Platte area.
The local office's own words before the first event, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS North Platte, NE wrote its last area forecast discussion before the first event at Jul 29, 5:31 PM CST, 50 minutes earlier. Its key messages:
Area Forecast Discussion National Weather Service North Platte NE 631 PM CDT Tue Jul 29 2025 .KEY MESSAGES... - A Slight (level 2 of 5) risk is in place for much of western and north central Nebraska into this evening. Damaging winds and heavy rainfall will be the primary threats. - Below average highs in the 70s to 80s are then expected for middle and late week, along with near daily threats for thunderstorms. - The threat for severe weather late week into the weekend remains uncertain. && .SHORT TERM /THROUGH WEDNESDAY NIGHT/... Issued at 231 PM CDT Tue Jul 29 2025 Isolated strong to severe thunderstorms will develop late this afternoon, becoming scattered to numerous this evening . Synoptically, a subtropical plume of moisture extends across Arizona and Colorado into western Nebraska. A mid level shortwave was indicated over central Colorado, which will lift northeast across the area tonight. At the surface, low pressure will deepen through the day across eastern Colorado and northwest Kansas, with an associated warm front lifting into far southwest Nebraska by late afternoon. Abundant low level moisture in place north of this boundary, where east to northeast winds exist and dewpoints as high as 70 to 75. The greatest instability (SBCAPEs 3500-4500 J/kg) north of the warm front across southwest into central Nebraska, along with the best PWATs (above the 90th percentile climo) in the pre- convective environment. Low level shear remains weak, though increasing westerly flow aloft into this evening. Effective shear does increase to 35-40kts across southwest into central Nebraska by late afternoon to support organized storms this evening. Scattered thunderstorm development will likely become widespread this evening, to form at least a few clusters. Any bowing segments will lead to the greatest threat for damaging winds, with guidance suggesting this occurring east of an Ogallala through Hyannis line into central Nebraska. Flash flooding will be another concern, as the widespread coverage of storms in a very moist environment will likely lead to locally heavy rainfall. High-res guidance suggests a swath of 2-4" of rain possible across central portions of the forecast area (mainly from near I80 north to Highway 2 and 91. The main activity will exit much of the area after 09Z, while continuing into eastern Nebraska and Iowa late. Stratus develop in the wake of this system late tonight through Wednesday morning, with a much cooler day due to persistent cloudiness, with highs remaining in the mid to upper 70s. Scattered showers and a few thunderstorms remain possible, mainly across north central Nebraska. Showers and storms may move in from the higher terrain Wednesday evening, mainly west of Highway 83 overnight. && .LONG TERM /THURSDAY THROUGH TUESDAY/... Issued at 231 PM CDT Tue Jul 29 2025 A flattened upper ridge Thursday through Saturday will become northwesterly Sunday through Tuesday. This will keep temperatures below average to end the week, with highs remaining in the 70s to low 80s. Thunderstorm chances will be limited in coverage through Saturday, and mainly confined to the west. Better chances across the area Saturday night through next Tuesday across the area as deep layer shear and instability increases to support some threat for strong to severe storms across western Nebraska. Highs will return to the 80s Sunday and Monday, with low 90s in the southwest by next Tuesday. && .AVIATION /00Z TAFS THROUGH 00Z THURSDAY/... Issued at 630 PM CDT Tue Jul 29 2025 Showers and thunderstorms are in progress across most of western and north central Nebraska, with thunderstorms producing heavy rainfall and gusty, erratic winds. Conditions may drop to MVFR in periods of thunderstorm activity. Later tonight, conditions deteriorate to IFR across portions of the region, as a low stratus deck builds in. With the heavy rain this evening and light winds overnight, believe that fog is likely to develop overnight in addition to the low ceilings. Skies remain cloudy in the afternoon, but gradually begin to improve to VFR conditions. Amendments may be needed in the short term to better capture the scattered nature of thunderstorms this evening. && .LBF WATCHES/WARNINGS/ADVISORIES... None. && SHORT TERM...Roberg LONG TERM...Roberg AVIATION...Richie
