Area Forecast Discussion For Western SD and Northeastern WY
National Weather Service Rapid City SD
300 PM MDT Mon Oct 16 2017

.DISCUSSION...(This Evening Through Monday)
Issued at 247 PM MDT Mon Oct 16 2017

Broad upper ridge is in place over the western half of the
country. At the surface, a weak trof is shifting east across the
Dakotas. Under mostly clear skies at 3pm, winds are out of the
north to northwest at 5 to 15 mph, and temperatures are in the mid
60s to mid 70s.

Persistent upper ridge will bring warm and dry weather to the
region through the week. Highs will be in the 70s each day, except
Wednesday will be slightly cooler following the passage of a weak
upper wave and its associated cool front. Some lower 80s will be
possible Thursday and Friday.

A trough will approach the area for the weekend, resulting in cooler
weather and some chances for light rain/snow showers on Saturday.
Warm and dry conditions look to return for Sunday into early next
week.
