Area Forecast Discussion For Western SD and Northeastern WY
National Weather Service Rapid City SD
137 AM MDT Sun Oct 15 2017

.DISCUSSION...(Today Through Saturday)
Issued at 136 AM MDT Sun Oct 15 2017

Upper trough is moving out of the northern plains,
while upper ridge builds over the west coast. A weak upper wave is
pushing into the northern Rockies, while its associated surface
trough approaches the CWA. Under clear skies, winds are westerly,
and temperatures are in the mid 20s to lower 30s.

Weak upper wave and surface trough will quickly cross the region
today, bringing some breezy northwest winds to the western SD
plains. Highs will be around 60, with mostly sunny skies. Lows
tonight will be in the 30s.

Low-amplitude upper ridging will keep weather dry and mild through
the week. Temperatures will be above average, with highs in the
upper 60s to mid 70s. A weak shortwave is expected to bring a slight
cooldown for Wednesday, but temps will warm again for the end of the
week. The next upper trough approaches the region late Friday into
Saturday, resulting in cooler weather and some spotty chances for
precipitation.
