The local office's own words before this special weather statement went out, 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 this special weather statement went out at Aug 7, 5:45 PM MDT, 8 minutes earlier. Its key messages:
- -Thunderstorm chances are the main concern late this afternoon and especially this evening. Strong gusty winds would be the main threat across portions of southwest Nebraska this evening. -Cooler and showery weather is expected both Thursday and Friday. Friday highs across portions of the region have the potential of being the coolest since August 1997. -Temperatures do moderate during the weekend, but will still remain below normal. -Areas of the next several days could see between 1-2" of rainfall. The precipitation will be showery/convective in nature, so amounts will likely vary with some not seeing those types of amounts.

Area Forecast Discussion National Weather Service North Platte NE 645 PM CDT Wed Aug 7 2024 .KEY MESSAGES... -Thunderstorm chances are the main concern late this afternoon and especially this evening. Strong gusty winds would be the main threat across portions of southwest Nebraska this evening. -Cooler and showery weather is expected both Thursday and Friday. Friday highs across portions of the region have the potential of being the coolest since August 1997. -Temperatures do moderate during the weekend, but will still remain below normal. -Areas of the next several days could see between 1-2" of rainfall. The precipitation will be showery/convective in nature, so amounts will likely vary with some not seeing those types of amounts. && .SHORT TERM /THROUGH FRIDAY/... Issued at 238 PM CDT Wed Aug 7 2024 A cold front is moving slowly southward through the Sandhills this afternoon. South of this front low-level southeasterly upslope flow is helping to maintain a moist instability axis from southwest Nebraska into the southern Nebraska Panhandle. Scattered thunderstorms are expected to develop across the higher terrain of a eastern Wyoming and northern Colorado late this afternoon ahead of an approaching shortwave. Effective shear profiles/instability are supportive of storm organization across the central and southern Panhandle late this afternoon. Recent runs of the HRRR and CAMs suggest a cold pool will form with a damaging wind threat becoming possible as storms accelerate southeastward across southwest Nebraska this evening. Other storms may develop along the southward sagging front across portions of north central Nebraska as mid-level FGEN increases after early evening. The most intense storms should exit the area by later this evening, but favorable jet dynamics and mid-level FGEN will remain in place through Friday morning. This seems a good set up for at least scattered showers. Elevated weak instability remains so some thunder is also possible. The other story will be the much cooler temperatures that will filter south into the region behind the cold front. Friday looks particularly cool, with the lingering cloud cover and possible morning light precipitation. Highs are forecast to be in the mid 60s across portions of the Sandhills and southwest Nebraska. The last time North Platte experienced a high of 65 degrees or cooler was August 11, 1997. Highs are forecast to be right around this mark, so this is an exceptionally cool pattern. && .LONG TERM /FRIDAY NIGHT THROUGH WEDNESDAY/... Issued at 238 PM CDT Wed Aug 7 2024 Below normal temperatures are expected through this weekend into the first of next week. Northwest flow aloft will persist, and a series of weak shortwaves will bring an increasing chance for showers/thunder back to the area Sunday night into Monday. Highs through the weekend should generally average in the lower to mid 70s. Highs Monday may moderate slightly, but with increased cloud cover and showers around may be hard pressed to reach much above 80. By the middle and end of next week, upper level ridging aloft begins to expand northward once again across the Rockies and western high plains. This will bring a return to at least normal temperatures. Monsoonal sub-tropical appears to develop northward within the expanding ridge. This will likely bring diurnal rounds of convection to the higher elevations of Colorado and Wyoming. Some of this activity may try and work eastward during the overnight hours, so there will be at least some chance for spotty rainfall. && .AVIATION /00Z TAFS THROUGH 00Z FRIDAY/... Issued at 638 PM CDT Wed Aug 7 2024 VFR conditions are expected across western and north central Nebraska tonight outside of thunderstorms. Any thunderstorms this evening and tonight may result in brief MVFR conditions and gusty, erratic winds across the Sandhills into southwest Nebraska, potentially impacting LBF. Timing of activity at LBF anticipated between 03Z to 05Z Thursday with the bulk of any thunderstorms remaining south of VTN. Will rely heavily on radar and satellite trends for possible amendments. Stratus development appears likely across western and southwestern Nebraska Thursday morning, with IFR CIGs anticipated. Though this appears to remain south and west of KLBF, this will need to be monitored with subsequent TAFs. && .LBF WATCHES/WARNINGS/ADVISORIES... None. && SHORT TERM...Taylor LONG TERM...Taylor AVIATION...Viken
