SIDNEY - A period of critical fire weather conditions were expected Sunday afternoon with wind gusts around 45 mph and minimum humidities between 15 and 20 percent. 

A red flag warning is in effect until 8 p.m. Sunday evening for the Nebraska Panhandle, southwest Nebraska and northeast Colorado.

A Red Flag Warning means that critical fire weather conditions are either occurring now, or will shortly. The combination of strong winds and low relative humidity can contribute to extreme fire behavior.

The National Weather Service office in Cheyenne says any fires that develop will likely spread rapidly. Outdoor burning is not recommended.

Mild temperatures, gusty winds and minimum humidities in the low and mid teens will yield near critical fire weather conditions each afternoon from Tuesday through Thursday.
