Area forecast discussion for western South Dakota and northeastern Wyoming 
National Weather Service Rapid City South Dakota 
445 am MDT Wednesday Oct 22 2014 


Short term...today through Thursday night 
issued at 249 am MDT Wednesday Oct 22 2014 


Water vapor shows upper wave pushing over The Rockies. Ahead of 
the wave there are clouds and a few showers...some of which are 
over western South Dakota. Surface trough/cool front are moving through the 
County Warning Area. Southerly winds ahead of the trough are keeping central South Dakota in 
the 60s...while temperatures are cooling into the 40s and 50s behind the 
front with breezy northwest winds. 


Upper wave will shift eastward today...pushing rain showers into 
central and eastern South Dakota. High pressure will quickly rebuild...and 
skies will clear. Breezy northwest winds are expected especially 
across northwest South Dakota...although boundary layer winds actually 
decrease during the day so winds will slowly diminish in the 
afternoon. Highs today will be in the 60s...with 50s in the Black 
Hills. Lows tonight will be in the 30s to low 40s. 


While the upper ridge returns over the northern plains on 
Thursday...a weak wave will pass through the area. Moisture will be 
lacking...and this disturbance will cause no more than some breezy 
winds across the southern County Warning Area. Skies will be mostly sunny...and 
temperatures will warm into the 60s and lower 70s. Lows will be in the 
upper 30s to upper 40s. If westerly winds Don/T get too calm 
overnight...downsloping flow may keep the eastern foothills a bit 
warmer. 


&& 


Long term...Friday through Tuesday 
issued at 249 am MDT Wednesday Oct 22 2014

Sunday allowing next trough to move through the area. It will 
bring a cold front and a few showers Sunday afternoon into Monday.
