NWS Forecaster Discussion




Area forecast discussion for western South Dakota and northeastern Wyoming 
National Weather Service Rapid City South Dakota 
506 PM MDT Monday Sep 1 2014 


Short term...this evening through Tuesday night 
issued at 118 PM MDT Monday Sep 1 2014 


Water vapor shows short wave moving from eastern Wyoming into western South Dakota...with 
upper ridge over the Pacific northwest building into the northern rockies. At the 
surface...weak cold front associated with short wave has moved through all but 
scntrl South Dakota with high pressure building into eastern Montana/eastern Wyoming. Scattered 
rain showers/thunderstorms and rain continue to develop over the County warning forecast area due to short wave. 


Tonight...short wave will push quickly east of the County warning forecast area this 
evening bringing rain showers/thunderstorms and rain to an end...and clearing skies later 
tonight. A brief period of breezy northwest winds will subside by late 
evening. 


Tuesday...upper ridge building eastward into the northern plains will bring 
mostly sunny skies and warmer temperatures. 


&& 


Long term...Wednesday through Monday 
issued at 118 PM MDT Monday Sep 1 2014 


An upper trough will cross the northern parts of the Continental U.S. 
From the Pacific northwest into the northern plains Wed/Thu. Models show decent 
agreement that the best forcing and bulk of precipitation will remain north 
of the County Warning Area...though far northwestern South Dakota could see some precipitation clip the area 
Wednesday night. In addition...surface low will cross the Dakotas Wednesday/Thursday 
with a strong cold front crossing the region Wednesday night...bringing a 
period of gusty northwest winds above average temperatures Wednesday will give 
way to below average temperatures Thursday. Beyond Thursday there are some diffs in 
models as a split-flow pattern sets up for the end of the week. 
However...in the mean there will be a trough over the west with a 
ridge over the scntrl-southeastern Continental U.S.. this will bring periodic short- 
wave troughs across the County Warning Area...albeit with limited forcing and 
moisture. For now will keep slight chance probability of precipitation for the periods with the 
most consistent timing of waves. Near average temperatures are expected for 
the end of the week. 


&& 


Aviation...(for the 00z tafs through 00z Tuesday evening) 
issued at 500 PM MDT Monday Sep 1 2014 


A departing upper level impulse will continue to support scattered/isolated 
rain showers/ts over the South Dakota plains early this evening...especially scentral South Dakota. Local 
MVFR ceilings/IFR visibilities are possible with the stronger cells. 
Otherwise...shortwave ridging ahead of the next Pacific northwest upper 
trough will support VFR conditions through the remainder of the 
period. 


&& 


Unr watches/warnings/advisories... 
South Dakota...none. 
Wyoming...none.
