The National Weather Service in Wichita will conduct a Tornado Drill at 11am tomorrow.
This test will be broadcast over NOAA All Hazards Weather Radio. Coffeyville will sound their warning sirens in conjunction with this drill. Everyone is encouraged to participate in the drill by practicing seeking secure, safe shelter from a tornado. If that's not possible then simply sheltering in place or discussing where you'd go and what you'd do are other options.
