.DISCUSSION...
Issued at 311 AM CDT Sun Mar 9 2025

Taking a look across the area, starting to see some scattered dry
spots across central SD and portions of southwestern MN where
relative humidity values have approached the 25-35 percent range
this afternoon. However, westerly to northwesterly winds speeds
continue to be on the marginal side with gusts between 20-30 mph
being recorded with the strongest wind speeds over our higher
elevation areas. With this in mind, our current SPS looks to be in
good shape with areas from Huron (Beadle) to Chamberlain (Brule)
still looking like the better corridor for truly elevated conditions
this afternoon. The SPS will run through about 5 PM before expiring.

Looking into Monday, we`ll have to keep an eye on fire weather side
of things again. Similar to today, an influx of warmer and drier air
will lead to decreasing dew points and thus lower relative humidity
values between 20-30 percent which is within critical thresholds.
However, the question comes with the wind speeds. While mixing will
gradually deepen during the afternoon hours, most soundings only
show a narrow window from 3pm to 7pm where we`ll be able to get
those stronger wind speeds (25-35 mph gusts) collocated with the
driest RH values with the focus being along and north of I-90. With
this in mind, the setup is decent enough to where we could see a few
hours of Red Flag conditions in the afternoon hours. However, with
lingering uncertainty regarding the wind speeds; decided to forgo
any issuance of headlines on this shift. Instead, we`ll continue to
message the elevated conditions north of I-90.

Debris burning is the number one cause of wildfires...so please
be careful with any use of fire.

...VERY HIGH FIRE DANGER...

The Grassland Fire Danger Index will reach the very high
category this afternoon. Very poor weather conditions and
very low moisture content of grasses, and other dry
organic material on the ground, indicate that dangerous
burning conditions exist. Fires will spread rapidly and
show erratic behavior. Outdoor burning is not recommended.

OUTLOOK FOR MONDAY AFTERNOON...The Grassland Fire Danger Index
will reach the very high category.

grasses. It is not intended for cured agricultural crops, nor
will it reflect conditions in road ditches which have been mowed.

...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.

...MODERATE FIRE DANGER...

The Grassland Fire Danger Index will reach the moderate
category this afternoon. Marginal weather conditions or
lowering moisture content of grasses, and other dry organic
material on the ground, indicate that there is some potential
for a fire to spread. Any outdoor burning should be closely
monitored.

...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 MONDAY AFTERNOON...The Grassland Fire Danger Index
will reach the moderate category.
