FNUS73 KSGF 210846 FWSSGF Spot Forecast for Busiek Purple Trail Burn Unit...Missouri Department of Conservation National Weather Service Springfield MO 346 AM CDT Sat Mar 21 2026 Forecast is based on ignition time of 0800 CDT on March 23. If conditions become unrepresentative...contact the National Weather Service. Please contact our office at 1-800-762-4363, if you have questions or concerns with this forecast. .DISCUSSION... Winds will prevail out of the east-northeast through the day on Monday. 20 ft winds between 15 and 20 mph and afternoon mixing heights between 3000 to 4000 ft will promote fair to good vent rates. The most likely scenario for relative humidity is for minimum values to drop into the upper 20s. A stable layer above 4000 ft will suppress any potential for deep, dry mixing that would otherwise introduce more uncertainty into the RH values, so forecast confidence is currently in the medium category. .MONDAY...
