.DISCUSSION...



Very warm temperatures continues to spread through the region 

Thursday, and will increase further Friday and Saturday. However, 

recent snow cover and melt will keep fuels wetter than normal, 

areas along the Missouri River will be more susceptible to higher 

end fire risks. Those risks grow Friday afternoon as relative 

humidity values fall near 20 to 25 percent, with occasional gusts 

to 20 mph. Saturday poses the greatest risk of the upcoming 

weekend with highs near 90 degrees, afternoon gusts of 15 to 20 

mph and relative humidity values near 15 to 20 percent. The 

grassland fire danger index in areas along the Missouri River will

rise to very high levels Saturday. 



A strong cold front moves through Sunday, raising humidity values

and dropping temperatures. However, gusty winds to 25 to 30 mph 

may lead to elevated fire weather conditions. 



Looking ahead, dry weather persists into next week, with 

increased risks for gusty afternoon winds and increasing fire 

danger at times.
