Area Forecast Discussion For Western SD and Northeastern WY National Weather Service Rapid City SD 157 PM MDT SAT JUL 30 2016 .SHORT TERM...(This Evening Through Sunday Night) Issued at 153 PM MDT Sat Jul 30 2016 20z surface analysis had boundary from central MT into northeast CO. Ahead of boundary, 1-2KJ/kg MLCAPE is developing. MLCIN eroding, especially over the higher terrain. CU field perking up a bit from southeast MT into the Black Hills, which is ahead of a very subtle shortwave over southeast MT, indicated by weak ACCAS field. With upper ridge building over the CWA per water vapour matinee, convective potential somewhat lower than yesterday but severe threat is similar with storms that develop given 15-20m/s 0-6km bulk shear. CAMs suggest strong to severe storms to occur in and near the Black Hills into south central SD where richest boundary layer moisture exists. Activity will shift southeast overnight. Temperatures will be near guidance. Sunday, upper ridge over the northern plains with upper low moving across south central Canada as tail end shortwave moves across MT/ND. Aforementioned boundary shifts east with modest MLCAPE developing ahead of it over western SD. MLCIN will be higher than today with enough shear for severe storms if storms develop in the afternoon and evening. Additional storms will occur Sunday night as elevated convection on the SD plains pops up late given 25-35kt low level jet. Temperatures will be near guidance ahead of boundary and above guidance in the drier air behind it. .LONG TERM...(Monday Through Saturday) Issued at 153 PM MDT Sat Jul 30 2016 Zonal flow aloft early in the week will give way to southwesterly flow Tuesday and Wednesday as upper level low moves across the Pacific NW and eventually into the southern Canadian Prairie Provinces. Weak disturbances in the flow will bring mostly diurnally driven shower and thunderstorm activity Monday and Tuesday, with the best chances across the Black Hills each afternoon. Above average temperatures can be expected across much of the area Monday and Tuesday, before a cold front passage late Tuesday night and Wednesday brings more seasonable temperatures for the rest of the week. Drier west-northwest flow late in the week should bring mostly dry conditions, with just a slight chance of thunderstorms at this point in some areas for Thursday and Friday. && .AVIATION...(For the 18Z TAFS Through 18Z Sunday) Issued At 153 PM MDT Sat Jul 30 2016 VFR conditions are generally expected across the area. A few thunderstorms are likely to develop later this afternoon, mainly across the Black Hills area, then track southeast across portions of southwest and south central SD into the evening hours. Local MVFR conditions and gusty winds will be possible near storms. && .UNR Watches/Warnings/Advisories... SD...None. WY...None. && SHORT TERM...Helgeson LONG TERM...26 AVIATION...26
