Area Forecast Discussion For Western SD and Northeastern WY National Weather Service Rapid City SD 202 PM MDT MON MAY 30 2016 .SHORT TERM...(This Evening Through Tuesday Night) Issued at 124 PM MDT Mon May 30 2016 20Z sfc analysis shows low pressure centered to the east of the Black Hills with a sfc trough extending southward to west of Valentine Neb. Sfc cool front has moved into western SD. Scattered showers and thunderstorms are increasing in coverage and strength over northwestern SD and over and east of the Blkhls as the sfc low continues to move east. Dewpoints are in the upper 50s to lower 60s to the east of the low, providing ample moisture for deep convection this aftn/eve. Diurnal heating, lift along the many sfc boundaries and sfc moisture have combined to push MUCAPE to 1500-3000J/KG to the east of the sfc cool front this aftn. Shear is sufficient to produce supercellular thunderstorms with some large hail already reported over part of nwrn SD this aftn. Expect to see the convection eventually develop into a n-s oriented line over central SD moving rapidly east this evening. Later this evening, subsidence and drying push most precipitation out of the CWA although a few lingering showers or possibly thunderstorms are not out of the question as main bubble of vorticity wraps around upper low. Temperatures will be near guidance. On Tuesday, the upper low stacks up with surface low in ND with a secondary upper shear axis and subsequent surface trough move through CWA. 850mb winds 20-30kts, so gusty winds expected given deep mixing and weak cold air advection. Moisture will be limited, but steep lapse rates should contribute to pops in the north through east during peak heating. Temperatures will be near guidance. Tuesday night, surface high moves in bringing quieter weather. .LONG TERM...(Wednesday Through Monday) Issued at 124 PM MDT Mon May 30 2016 An upper level ridge will build over the western CONUS and the Northern Plains from mid week into next weekend. Mainly dry weather is expected through the extended period. Highs Wednesday will be in the 70s, warming to the 80s Thursday into next weekend. && .AVIATION...(For the 18Z TAFS Through 18Z Tuesday) Issued At 124 PM MDT Mon May 30 2016 Strong to severe thunderstorms will move across western South Dakota this afternoon and evening. MVFR to IFR visibility and gusty winds are possible in/near any storms. Strong northwest winds of 20-30 kts with gusts near 40 kts will follow a cold front this evening. Strongest shower/storm activity will shift east of the area by 06Z tonight with VFR conditions expected through Tuesday morning. && .UNR Watches/Warnings/Advisories... SD...None. WY...None. && SHORT TERM...10 LONG TERM...15 AVIATION...15
