Area forecast discussion, Jun 5, 4:18 PM MST, 2 hours 35 minutes before
Area Forecast Discussion For Western SD and Northeastern WY National Weather Service Rapid City SD 518 PM MDT Tue Jun 5 2018 .DISCUSSION...(This Evening Through Tuesday) Issued at 144 PM MDT Tue Jun 5 2018 The upper ridge persists over the central CONUS, and the next shortwave to affect the region is moving over the Rockies. Skies across the Dakotas are mostly sunny. At the surface, low pressure rests over central SD, and a cold front is draped across the CWA. Winds are light, and temperatures are climbing into the 80s and 90s. The shortwave will push into the region late this afternoon, with the strongest part crossing northern SD this evening. CAMs are showing storms moving into the southwestern CWA late this afternoon, which should stay sub-severe given weak instability there, but cannot rule out some strong winds. However, stronger storms are progged to move into northwestern SD later this evening, and with 2000-3000 J/kg MLCAPE and 35-50 kts of 0-6 km bulk shear, some may become severe. Besides gusty winds and large hail, heavy rain will be possible (PWATs are 175% of normal), but storm motion around 20 kts should keep storms moving. These storms will track eastward later tonight. Wednesday morning will be dry, but the next round of storms will begin to move in from the west during the afternoon, as another shortwave pushes into the region. Best instability will be across northeastern WY and southern SD, and shear will be sufficient for some strong to severe storms to develop in those areas. However, high pressure may keep much from happening across much of our CWA. Return flow sets up across the area as high pressure slides eastward, and air with 60+ degree dew points will advect into the CWA. MLCAPE of 3000+ J/kg will develop by mid-afternoon. Yet another shortwave will slide into the region Thursday evening. Severe thunderstorms are expected, supported by 0-6 km shear around 35 kts. A strengthening low-level jet could keep storms going well into the night. Friday into the weekend, upper ridging will keep weather mostly dry, although a few weak waves moving through southwest flow could bring some isolated showers/storms. Highs through the weekend will be generally in the 80s. && .AVIATION...(For the 00Z TAFS Through 00Z Wednesday Evening) Issued At 515 PM MDT Tue Jun 5 2018 Outside of precipitation, VFR conditions will continue through Wednesday afternoon. A cluster of thunderstorms moving into southwestern SD will bring gusty winds and local MVFR conditions. Another cluster of storms will move across southern MT into northwest SD tonight with local IFR conditions, gusty winds, and large hail. && .UNR WATCHES/WARNINGS/ADVISORIES... SD...None.
