Rangeland Fire Danger Statement

National Weather Service Sioux Falls SD

422 AM CDT Sun Apr 27 2025



.DISCUSSION...



Increasing low level moisture will result in cloudy skies and

rising dew points for today. Clouds will keep temperatures on the

cooler side, yielding afternoon RH values of 60 to 70 percent, so

the fire danger will be diminished.



Becoming much warmer on Monday, and with dew points in the upper

50s to lower 60s, afternoon RH values will run 35 to 50 percent.

In spite of that, it will be a windy day, and this will result in

a High to Very High fire danger from the Interstate 29 corridor and

eastward. Showers and thunderstorms are expected by afternoon

however.

...HIGH FIRE DANGER...



The Grassland Fire Danger Index will reach the high category

this afternoon. Unfavorable weather conditions and low

moisture content of grasses, and other dry organic material

on the ground, indicate that there is a high potential for

a fire to spread.. Outdoor burning should be restricted to

early morning or evening hours, when wind speeds are usually

lower and the relative humidity is higher.



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

will reach the very high 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.
