Area Forecast Discussion For Western SD and Northeastern WY
National Weather Service Rapid City SD
522 PM MDT Sat Oct 14 2017

.DISCUSSION...(This Evening Through Saturday)
Issued at 256 PM MDT Sat Oct 14 2017

Water vapor imagery shows an broad upper trough centered across the
central third of the CONUS with the main axis now crossing the
CWA. KUDX radar shows rain showers quickly dissipating as the move
eastward across south central to southwest SD. This trend will
continue through the late afternoon as the drier air enters the
CWA behind the departing wave. Skies will clear out early this
evening with lows dropping into the 20s to low 30s. Models are
showing a fast moving wave pushing through northeastern MT into ND
late tonight into Sunday. With dry air over the region, no precip
will occur. Instead some passing clouds and a return of gusty
northwest winds...though not as strong as today. Highs will be in
the 50s to mid 60s. Low amplitude ridging can be expected Monday
and Tuesday with temperatures warming into the 70s across most
locations. Upper flow becomes more zonal for the second half of
the week, but dry weather and highs mostly in the 70s will
continue.
