FNUS73 KFSD 091032 FWSFSD Spot Forecast for Black Rush Lake...USFWS National Weather Service Sioux Falls SD 532 AM CDT Fri May 9 2025 If conditions become unrepresentative, contact the National Weather Service. ...FIRE WEATHER WATCH IN EFFECT FROM SUNDAY MORNING THROUGH SUNDAY EVENING... .DISCUSSION... Much warmer and very dry conditions are expected today as temperatures climb into the upper 80s and afternoon humidity drops below 25 percent. Morning downslope winds will favor a southwest direction 10-15 mph with occasional gusts to near 20 mph. Wind direction will gradually swing more to the west as the morning progresses, ahead of an approaching cold front. This front, arriving mid-late afternoon, will bring a low (20%-30%) chance for high-based light rain showers or perhaps a stray thunderstorm. Any shower/storm, or even virga (showers dissipating before reaching the ground), will bring a potential for erratic stronger wind gusts, possibly as high as 40-50 mph. This chance for showers looks to be greatest after 3 to 4 pm this afternoon in the burn location. .REST OF TODAY... Max temperature.....Around 87. Min humidity........19 percent.
