Special Weather Statement issued May 9 at 6:25AM CDT by NWS Twin Cities/Chanhassen MN
Effective: Sat May 9, 2026, 6:25 AM
Expires: Sat May 9, 2026, 7:00 PM
Another elevated fire weather day is expected across the area that has yet to fully begin their growing season from western to central Minnesota. Winds are expected to increase during the daylight hours, with sustained winds increasing to 15-20mph with gusts as high as 30mph out of the northwest. As winds increase, temperatures will warm into the low 60s, allowing relative humidity to fall into the low to mid 20 percent range this afternoon. The combination of the relative humidity and winds will lead to the elevated conditions, however peak wind gust strength should stay below Red Flag criteria. Check burning restrictions and fire danger levels and consult with fire officials before burning. For more information on burning restrictions for Minnesota, see www.dnr.state.mn.us/forestry/fire/firerating_restrictions.html.
