.DISCUSSION...

Issued at 252 PM CDT Sat Oct 4 2025



Hot, dry and windy conditions will lead to widespread High to

Very High Grassland Fire Danger today. Afternoon minimum

humidity of 27-40%, with driest conditions in south central

South Dakota. However, south winds gusting as high as 35 to 40

MPH will overcome the marginal humidity levels, especially where

grasses are more cured or crops are ready for harvest. With

this in mind, please use caution with machinery that gets very

hot or creates sparks.



Breezy conditions continue overnight and into Sunday. Areas west

of I-29 can expect gusts of 30-35 mph overnight and into Sunday

late morning. Areas to the east could see gusts of 35-40 mph in

to the early afternoon. Humidity levels will fall to 30-40%, and keep

the Grassland Fire Danger in the High category in many areas,

so continued caution is advised.



Through the day Sunday a cold front moves through the region.

Temperatures will begin to cool Sunday, and be in the 60s for

Monday. Dry conditions with cooler temperatures and lighter

winds are expected for next week, allowing for less dangerous

harvesting conditions.



People are urged to exercise extreme care with respect to outdoor

activities that could cause grass fires. Avoid equipment that can

cause sparks near dry grass or brush. Do not toss cigarettes on

the ground. Report new fires quickly to the nearest fire

department or law enforcement office.
