Area forecast discussion, Sep 4, 1:10 PM MST, 1 hour 14 minutes before
Area Forecast Discussion For Western SD and Northeastern WY National Weather Service Rapid City SD 210 PM MDT SUN SEP 4 2016 .SHORT TERM...(This Evening Through Monday Night) Issued at 207 PM MDT Sun Sep 4 2016 Mean western conus trough and associated impulses will continue to affect the region in the period. A potent front side impulse is in the process of advecting toward the region this afternoon with flow increasing in the mid levels ahead of this feature. Destabilization will continue this afternoon and evening with convection developing and becoming more numerous through evening. Strong flow will support deep layer shear in excess of 50 knots with mean ll cape of 1-2.5 KJ/Kg, highest over scentral SD...supporting a good chance of severe storms over the se half. Initial convection over the far sw will likely be single cell/supercells. Convection will quickly organize into a linear connective system (given wind profiles aloft) with large hail and damaging winds possible as it progresses across the se third. Outside of this area, mainly sct showers and few isold ts will be possible. Convection chances will continue through the night as the main jet streak and upper trough lifts over the region. Patchy fog will also be possible tonight, esp across the western third. Cyclonic flow will remain over the region through Monday, with additional diurnal shra/ts possible, best chance across the far nw closest to the best lsa. Cooler conds expected nw 2/3 with highs slightly below seasonal norms most areas, coolest over far nw areas. .LONG TERM...(Tuesday Through Sunday) Issued at 207 PM MDT Sun Sep 4 2016 Slow moving upper trof to the west of the region will finally start moving east across the Rockies and plains Tuesday and Wednesday. Good chances for showers and a few storms will continue, with the best chances looking to be Tuesday night into Wednesday morning. As trof moves east of the area late in the week, drier zonal flow aloft will develop. Will still keep low chances for showers in some areas late Thursday through Friday. Temperatures will be near or slightly below seasonal averages through the period, with highs mostly in the 70s. && .AVIATION...(For the 18Z TAFS Through 18Z Monday) Issued At 207 PM MDT Sun Sep 4 2016 VFR conditions generally expected across southern and central SD through late afternoon. Areas of IFR ceilings with light showers will persist across Northeast WY and far western SD, including KGCC KSPF KRAP. Scattered thunderstorms will move through much of the area between mid afternoon and mid evening, with strong to severe storms with large hail and damaging winds from the Black Hills eastward. MVFR/IFR cigs will then overspread much of the forecast area overnight into early Monday. && .UNR Watches/Warnings/Advisories... SD...None. WY...None. && SHORT TERM...JC LONG TERM...15 AVIATION...15
