.DISCUSSION...

Grassland Fire Danger will be elevated this afternoon thanks to
gusty winds at 25-30 mph. Despite minimum relative humidity
values being well above critical (>40%), with grasses and crops
nearly cured any fires have the potential to spread quickly.
Please use caution with hot machinery, sources of sparks, and
report any fires immediately.

Low Fire Danger is expected for Monday with cooler temperatures,
light winds, and minimum RH values >40%. Tuesday will be slightly
warmer and drier with minimum RH values >30%, however winds remain
light. Elevated Fire Danger is possible Wednesday as southerly
winds increase to 20-25 mph and minimum RH values fall to around
30% for southwestern Minnesota and northwestern Iowa. The
strongest winds will be located over central South Dakota,
displaced from the lowest RH values.
