The entire eastern half of Minnesota is under a fire weather watch for Sunday afternoon and evening, meaning critical fire weather conditions are likely.
What are critical fire weather conditions?
According to the National Weather Service, it's the combination of warm, dry air and strong winds.
Sunday in Minnesota will be all of the above, with temperatures warming to around 70 degrees Sunday afternoon "coupled with strong southerly winds and low relative humidities will create conditions where fires could grow and spread very quickly."
Winds will be sustained between 10-20 mph with southerly gusts up to 35 mph. The humidity will be very low, at just 15-20 percent.
"Any fires which develop will spread quickly among dry vegetation and quickly grow out of control," the NWS says.
Outdoor burning is strongly discouraged on Sunday.
The dry air will be invaded by more humidity Sunday night into Monday as an approaching storm system brings the threat of rain and storms early in the week.
