Area Forecast Discussion For Western SD and Northeastern WY
National Weather Service Rapid City SD
247 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.
