Area forecast discussion, Jul 9, 12:23 PM MST, 1 minute before
Area Forecast Discussion For Western SD and Northeastern WY National Weather Service Rapid City SD 123 PM MDT Tue Jul 9 2019 .DISCUSSION...(This Evening Through Tuesday) Issued at 105 PM MDT Tue Jul 9 2019 Water vapor shows upper low center near the WY/MT border, with surface analysis placing associated low over ND. Convection is initiating early this afternoon across northeast WY. Nose of 100+kt speed max rounding the base of the upper low is aiding convective development early this afternoon across northeast WY, and this activity will slowly translate eastward across the area this afternoon and early evening. MLCAPE is rather modest, only up to around 1000J/KG, but effective bulk shear will increase to 50-60kts in the next few hours as upper speed max moves in. Best focus for supercells will generally be from northeast WY into southwest SD. Main threats will be large hail and damaging winds. Threat for severe storms will wain quickly with loss of heating this evening. Showers will linger across northwest SD this evening as main upper low moves through, with upper ridge then building in for Wed and Thu. Much warmer conditions expected with little to no precip expected. Rather flat upper ridge will dominate through the weekend into early next week, with the main storm track remaining to our north. The result will be mainly above average temps with a few storms from time to time. && .AVIATION...(For the 18Z TAFS Through 18Z Wednesday) Issued At 1137 AM MDT Tue Jul 9 2019 Scattered showers and thunderstorms are expected to redevelop across much of the area this afternoon and evening, a few storms possibly strong to severe with strong wind gusts. Brief MVFR conditions are possible near any storms. Gusty northwest winds will develop by early afternoon across northwest into parts of west central SD behind a passing cold front. Some gusts of 25 to 35 kts are expected in these areas. && .UNR WATCHES/WARNINGS/ADVISORIES... SD...None. WY...None. && DISCUSSION...Johnson AVIATION...13
