Area Forecast Discussion For Western SD and Northeastern WY
National Weather Service Rapid City SD
1124 AM MDT Sun Oct 16 2022

.DISCUSSION...(Today Through Saturday)
Issued at 246 AM MDT Sun Oct 16 2022

Current satellite imagery shows clearing skies over western SD 
and northeastern WY. Winds across the region are light and 
variable with temperatures ranging from the 30s to 40s. Fog and 
low clouds are developing in the Black Hills of WY and portions of
south central SD. 500 mb analysis shows upper ridging centered 
over the Pacific Northwest and ridging over the midwest, putting 
our area under northerly flow.

Today will be cool with seasonably breezy northerly winds as a 
high pressure system passes off to our north. The upper level 
pattern looks to be fairly stagnant for the next few days as the 
upper low meanders over the Great Lakes region and Ontario. The 
upper ridge will slowly drift eastward, the axis staying over the 
Rockies and keeping our area under northerly flow. Generally, the 
weather will stay dry with temperatures warming through the week. 
The pattern becomes more zonal towards the end of the week with 
mid-level flow shifting from northerly to westerly. Fire weather 
concerns may return in the latter half of next week as 
temperatures warm and sfc winds pick up.
