Area forecast discussion, Sep 20, 5:01 PM MST, 1 hour 4 minutes before
Area Forecast Discussion For Western SD and Northeastern WY National Weather Service Rapid City SD 601 PM MDT Fri Sep 20 2019 .DISCUSSION...(This Evening Through Friday) Issued at 125 PM MDT Fri Sep 20 2019 Water vapor shows deep upper low over northern UT/southeast ID. Notable short wave lifting out of western SD into ND. Convection initiating over southeast WY and the CO front range indicative of the next short wave, and this is the activity that will be moving into our southwest zones by very late afternoon. At the surface, frontal boundary is stalled out over western SD. Mainly elevated convection early this afternoon will be most notable in far northwestern SD before lifting out of the area late this afternoon. Main focus for severe storms later this afternoon and evening will be across west central and southwest SD. Atmosphere should remain largely capped (outside of the Black Hills) until later in the afternoon. Approaching short wave will lead to thunderstorms moving into northeast WY and southwest SD in the 4-6 pm range, with activity then spreading north and east across the remainder of CWFA this evening and overnight. Better chance for severe storms will generally be around the Black Hills and areas south/east of the Black Hills. Storms initially may be discreet and there is some threat for tornadic activity, especially near the frontal boundary over southwest SD. Storms should then become more linear as the activity spreads north/eastward with more of a hail/wind threat at that time. Most intense storms should end around or just after midnight, with precip transitioning more showery overnight in our northern zones. Upper low shifts into western ND Saturday morning, then into southern Manitoba by late afternoon. Main impact for our area will be gusty northwest winds, especially on the SD plains and a wind advisory may be needed (will hold off issuing for now until any severe weather highlights have ended). Showers will likely persist much of the day from northeast WY through the northern Black Hills into northwest SD with temperatures there holding in the 50s to lower 60s, but a bit drier and warmest south/east of the Black Hills. Dry and warmer temps expected Sunday, but another short wave rotating around the main upper low/trof could keep west/northwest winds on the breezy side. Upper ridge will bring dry and warmer conditions for early next week. A few showers and slightly cooler weather towards mid week with another frontal passage. Even more unsettled weather likely towards the tail end of the week and weekend. && .AVIATION...(For the 00Z TAFS Through 00Z Saturday Evening) Issued At 601 PM MDT Fri Sep 20 2019 Showers and thunderstorms will continue to develop and move northeast across much of the area tonight as a cold front slowly moves east of the region. Some storms could be severe in the evening with large hail, strong wind gusts, and heavy rain. MVFR conditions can be expected in the vicinity of storms and will also develop across portions of the area later tonight into Saturday. Northwest winds will increase Saturday morning as the upper system moves across the Dakotas. Chances for showers will linger for areas mainly from northeast WY to the northern Black Hills and northwest SD on Saturday. && .UNR WATCHES/WARNINGS/ADVISORIES... SD...None.
