NWS Forecaster Discussion




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.
