Critical Fire Weather Conditions Today

Conditions Favorable for Wildfire Growth

A surface trough of low pressure and associated cold front will be shifting east today. Along and behind the cold front, west to northwest winds will increase to 30 to 40 miles an hour, with some gusts over 50 miles an hour possible.  The main region of  fire weather concern, will be along and east of a line, from Valentine to Imperial, with the eastern boundary from Butte, through Brewster and Stockville. High temperatures this afternoon will vary from the middle 60s in the north through the middle 70s over southern parts of the region. Relative humidities are expected to lower below 15 percent in some areas, by late this afternoon. The combination of the frontal passage, increasingly gusty west to northwest winds, and some remaining dry residual grasses, will create critical fire weather conditions. If any wildfires occur rapid growth is possible.

A Red Flag Warning is in effect  from 100 PM CDT through 700 PM CDT, for parts of western and north central Nebraska.  Despite some green up which has occurred early this spring, enough dry residual grasses remain in place as fuels for growth of wildfires, according to fire managers.

A High Wind Warning is in effect from 1000 AM MDT through 800 PM MDT for the eastern Nebraska Panhandle and the western Sandhills, where west to northwest winds gusting as high as 60 MPH are possible. Further east, wind gusts as high as 45 MPH are expected.
