748 FXUS63 KUNR 101944 AFDUNR Area Forecast Discussion For Western SD and Northeastern WY National Weather Service Rapid City SD 144 PM MDT Thu Jul 10 2025 .KEY MESSAGES... -Cold front will move through the region late tonight with cooler, breezy, and showery weather Friday -Dry this weekend with temps warming back up -Unsettled weather returns next week, with daily shower and thunderstorm chances possible && .DISCUSSION...(This Evening Through Thursday) Issued at 116 PM MDT Thu Jul 10 2025 This mornings band of thunderstorm activity has enveloped the region on a thick cloud canopy which has limited daytime heating across portions of the Black Hills. Maximum temperatures were adjusted some 3-6 degrees cooler to account of this. Otherwise the shower and thunderstorm activity continues to decrease in aerial coverage and severity as we continue to progress through the afternoon hours. We are still tracking a cold front to push through the region this evening and in its wake, will bring cooler temperatures to the region tomorrow. We will still hold on to low end (30% POP) chances for tomorrow afternoon. Expect minimal impacts with any shower and thunderstorms that do develop tomorrow as there will be limited instability and moisture to contend with. Forecast over the weekend looks on track and we can expected drier conditions with warming temperatures throughout the weekend with temperatures climbing back into the mid to upper 90s for Sunday. Heading into next week the longwave pattern shifts back toward a somewhat active pattern as a progged baroclinic zone develops and stalls out across the upper Northern Plains and we bring back low level moisture to the region. Embedded in the longwave pattern is a shortwave an coinciding cold front that could be a catalyst for more organized thunderstorm develop and it will be something we need to watch for Tuesday afternoon into the evening hours. && .AVIATION...(For the 18Z TAFS Through 18Z Friday) Issued At 1130 AM MDT Thu Jul 10 2025 Generally VFR conditions are expected.
