A zonal flow pattern over southeast Wyoming will lead to strong winds on both Thursday and Friday. Wind gusts in excess of 45 MPH are expected on Thursday and 35 MPH on Friday. A dry airmass in place both days will lead to relative humidity values below 10 percent. Overnight humidity recoveries Wednesday and Thursday night will also be poor. The combination of wind and extremely dry conditions will lead to increased fire danger. However, given recent moisture and green up of vegetation across the area, fuels are currently non-critical. Despite this, outdoor burning is still not recommended given the conditions on Thursday and Friday. Use caution, don't be the spark!
