The return of warmer weather expected today brings a warning about wildfires.

Jackson County, like most of Missouri and the eastern edge of Kansas, is under a red-flag warning from 10 a.m. and 8 p.m. That means an extreme risk of wildfires. Conditions are dry, and today’s wind and low humidity raise the risk of fires getting out of control.

The peak time of concern is between 1 p.m. and 6 p.m.

Today’s high is forecast at about 45. A relatively warm wind out of the southwest will blow at 20 to 30 mph and gust to 40 mph. Meanwhile, the air’s relative humidity is expected to be just 20 to 25 percent.

The National Weather Service, which posted the red flag warning, says the grassland fire danger index for Jackson County today is “very high.”

Under such conditions, authorities caution people to avoid any outdoor burning and to be especially careful about snuffing out and disposing cigarettes.
