Area forecast discussion for western South Dakota and northeastern Wyoming National Weather Service Rapid City South Dakota 503 PM MDT Sat Apr 25 2015 Short term...this evening through Sunday night issued at 306 PM MDT Sat Apr 25 2015 Current surface analysis shows low pressure over northeast Wyoming...with cold front back into central and southwest Wyoming...and warm front extending across portions of northeast Wyoming into southwest South Dakota and western Nebraska. Upper level analysis shows an area of low pressure over western Illinois...with shortwave ridge over the northern plains and trough along the West Coast. Southwest flow extends from the Great Basin region into the northern and Central High plains. Skies are mainly cloudy across much of the County Warning Area. Kudx radar shows showers and thunderstorms have developed near the warm front...moving east-northeast across far northeast Wyoming and southwest South Dakota. A couple of cells look like they could be producing some small hail. Other activity has developed over the northeast slopes of the Black Hills as well. Temperatures range from the upper 40s across far northwest South Dakota to around 60 over portions of southern South Dakota and northeast Wyoming. Short range models in pretty good agreement over the next couple of days...with some relatively minor differences on timing and track of main precipitation tonight and Sunday. Southwest flow ahead of West Coast system will continue to bring showers to much of the area through the weekend... especially northeast Wyoming and far western South Dakota. One disturbance is across eastern Wyoming now...with another one across southern Utah. The best chances and heaviest rainfall potential will be late this afternoon through Sunday afternoon. Forecast calls for general rainfall amounts of close to a half inch to one inch across much of northeast Wyoming and far western South Dakota...with locally higher amounts expected where heavier showers and storms develop through the evening. For late today and this evening...showers and isolated to scattered thunderstorms will continue to develop and move across northeast Wyoming and much of western South Dakota. The heavier precipitation and thunderstorms should dissipate overnight...with mostly lighter showers expected late tonight. Will keep highest probability of precipitation...80+ percent...over the Black Hills area. Lows will be in the middle 30s to middle 40s. Forecast profiles show even the highest elevations of the Black Hills remaining as rain later tonight/early Sunday...so will not have any mix in the forecast. Will go with patchy fog across the entire County Warning Area for later tonight/early Sunday. As developing low within the upper trough moves across The Four Corners area into the southern rockies on Sunday. Shortwave energy will still rotate northward into the central and northern High Plains as narrowing ridge holds over the eastern plains. The shortwave over Utah should move into our area late tonight/Sunday morning. Will keep best chance for showers on Sunday over northeast Wyoming and the Black Hills area. Raised probability of precipitation to 80+ for these areas. Potential for thunder is rather low on Sunday...but would not be surprised to see a few strikes over the far southern County Warning Area during the afternoon. Highs will range from the middle 40s over northeast Wyoming and the Black Hills to around 60 over central South Dakota...where mainly dry conditions and a little sunshine is expected. Showers will decrease in coverage Sunday night...especially after midnight. Lows will mostly be in the middle 30s to lower 40s...with the higher Black Hills into the lower 30s by morning. Long term...Monday through Saturday issued at 306 PM MDT Sat Apr 25 2015 Precipitation chances will linger Monday as northern stream trough axis crosses the northern plains. Upper level ridge then builds from The Rockies into the northern plains early to middle week...bringing dry and warmer conditions to the area. As the ridge shifts east of the area late in the week...southwest flow will develop and lead to chances for rain showers/thunderstorms and rain at times...mainly during the afternoon/evening hours. Temperatures by the end of the week will push well through the 70s...and into the 80s in some areas. && Aviation...(for the 00z tafs through 00z Sunday evening) issued at 502 PM MDT Sat Apr 25 2015 IFR/LIFR stratus over most areas will continue into Sunday. Rain showers/isolated thunderstorms and rain will continue to develop this afternoon/evening...with precipitation becoming more widespread tonight into Sunday. MVFR/IFR visibilities expected near heavier precipitation. && Unr watches/warnings/advisories... South Dakota...none. Wyoming...none. && $$ Short term...26 long term...Johnson aviation...jc
