Rangeland Fire Danger Statement

National Weather Service Sioux Falls SD

325 AM CDT Thu May 8 2025



.DISCUSSION...



Dry and mostly clear conditions today. Winds will be light (7 mph

or less) and variable through the day. If direction becomes 

prevailing, would be east to southeast. Lightest winds expected

along and west of I-29. Despite relatively efficient mixing, flow

aloft is also weak, which may hinder smoke dispersion. Highs 

today in the 70s to near 80 with RH values dropping to 25-30%.



Outside of low (less than 25%) chances of showers and storms

along/north of I-90 Friday afternoon and evening, dry weather

prevails into early next week. Temperatures continue warming with

highs this weekend into Monday in the 80s to near 90. Strong 

southerly winds gusting to around 40 mph and low RH could lead to 

areas of critical fire conditions Sunday and at least into Monday.



Slightly cooler by mid next week, with low (less than 30%) rain 

chances returning.

...LOW FIRE DANGER...



The Grassland Fire Danger Index will reach the low category 

this afternoon. Favorable weather conditions or a high moisture 

content of grasses, and other dry organic material on the 

ground, indicate that the probability of a fast moving fire is 

low. Outdoor burning under these conditions can usually be 

with reasonable safety precautions, but should be monitored.



OUTLOOK FOR FRIDAY AFTERNOON...The Grassland Fire Danger Index

will reach the low category. 



The grassland fire danger product reflects fire danger for native

grasses. It is not intended for cured agricultural crops, nor

will it reflect conditions in road ditches which have been mowed.
