102 FXUS63 KUNR 131123 AFDUNR Area Forecast Discussion For Western SD and Northeastern WY National Weather Service Rapid City SD 523 AM MDT Fri Sep 13 2019 .DISCUSSION...(Today Through Thursday) Issued at 140 AM MDT Fri Sep 13 2019 Mean ridging expected over the central Rockies and Northern Plains through early next week. This will support warm and dry weather. One last WNW flow impulse will traverse the region tonight, supporting nothing more than a few mid clouds and a wind shift tonight into Sat morning locally. A warming trend can be expected today through Monday, with 70s today, 80s Sat, and 80s and few 90s Sun-Mon. NW Pac upper trough will drop into the western CONUS next week, slowly progressing east in the week. Forecast models are offering a variety of run-run solutions as to how this system will evolve, either ejecting into the central CONUS in pieces or as one larger system. Rain chances and degree of temp moderation will remain muddled until a better grasp of these details is ascertained. Hence, rain chances currently remain low Tue night on. One thing that is certain is that a cooling trend looks likely for the second half of the next week. && .AVIATION...(For the 12Z TAFS Through 12Z Saturday Morning) Issued At 523 AM MDT Fri Sep 13 2019 VFR conditions are generally expected through Saturday morning. && .UNR WATCHES/WARNINGS/ADVISORIES...
