Area Forecast Discussion For Western SD and Northeastern WY National Weather Service Rapid City SD 509 PM MDT Mon Aug 7 2023 .DISCUSSION...(This Evening Through Monday) Issued at 121 PM MDT Mon Aug 7 2023 Weak shortwave energy is helping to produce some showers and isolated, sub-severe storms across our CWA, as another weak shortwave follows, and a stronger wave moves ashore over the Pac NW. Winds are light and variable at the surface. Under mostly cloudy skies, temperatures are only in the 60s and lower 70s (50s in the BH). As the second shortwave pushes into our region tonight, a few more thunderstorms are expected develop. However, with limited heating today, CAPE will be low. Better CAPE/shear will be to our south, although a stray strong storm could skirt our CWA. Light winds and plentiful moisture could result in some patchy fog across southwestern SD late tonight/early Tues morning. The stronger shortwave will cross the Rockies Tuesday morning. Some WAA will allow MLCAPE to rise near 1000 J/kg, and 0-6 km shear will be around 30 kts close to the NE border. As the low slides just southwest of our CWA, a couple strong to severe storms will be possible Tuesday afternoon and evening , especially across parts of northeastern WY and southwestern SD. Highs Tuesday will be mainly in the 70s. Transient ridging will allow for a warm and dry Wednesday, with highs in the upper 70s to 80s. The next shortwave trough will skirt the northern CONUS. Most of its energy will stay to our north, but storms may move through northwestern SD. Buoyancy and shear will be sufficient for a few strong to severe storms. Upper flow will become northwesterly, with a few embedded shortwaves, through the weekend. Some isolated storms will be possible with the weak shortwaves, but mainly dry weather can be expected Friday through Sunday. Temperatures will be near to slightly below seasonal averages, in the 80s. && .AVIATION...(For the 00Z TAFS Through 00Z Tuesday Evening) Issued At 504 PM MDT Mon Aug 7 2023 Isolated/scattered showers/TS will slowly subside this evening as they move into south-central SD and dissipate late. Additional active TSRA will develop Tuesday afternoon, especially near the SD/NE border. Outside of storms, VFR conditions expected except for local MVFR VSBYS due to BR near the SD/NE overnight. In/near storms, brief MVFR/IFR conditions are possible. && .UNR WATCHES/WARNINGS/ADVISORIES... SD...None. WY...None. && DISCUSSION...Pojorlie AVIATION...Helgeson
