NWS Forecaster Discussion




Area forecast discussion for western South Dakota and northeastern Wyoming 
National Weather Service Rapid City South Dakota 
1113 am MDT Thursday may 28 2015 


Short term...today through Friday night 
issued at 320 am MDT Thursday may 28 2015 


Upper trough over western Montana will shift eastward today 
increasing cyclonic flow over the area. At the surface...a slow 
moving north-S oriented trough will be located east of the Black 
Hills this morning. Abundant ll moisture and increased 
instability due to diurnal heating along with enhanced 
convergence along the surface trough will support widespread 
convection over the forecast area today. A few stronger storms 
will be possible over central South Dakota to the east of the 
surface trough where ll moisture transport will lead to ml cape 
around 1700j/kg this afternoon. Locally heavy rainfall will be possible with 
any thunderstorms over the Black Hills this afternoon which could increase 
flooding potential over the creeks and streams which are already 
running high due to the recent excessive rainfall. Another 
trough/cold front will shift southward tonight supporting an 
enhanced area of convergence with rain showers chances continuing 
overnight. The higher probability of precipitation will shift southward with the surface 
boundary on Friday/Friday night. 


Long term...Saturday through Wednesday 
issued at 320 am MDT Thursday may 28 2015 


Upper level ridge develops over the northern plains for 
the weekend...as Canadian surface high pressure settles into the 
area. Cooler temperatures are expected on Saturday...but thermal 
ridge will build into the region Sunday and Monday...allowing for a 
warm-up...with small chances of showers and thunderstorms. Greater 
precipitation chances return for the middle of next week as western 
trough redevelops and upper flow over the northern plains becomes 
southwesterly.
