RANGELAND FIRE DANGER STATEMENT
NATIONAL WEATHER SERVICE SIOUX FALLS SD
256 PM CST THU FEB 27 2025
DISCUSSION
ISSUED AT 222 PM CST THU FEB 27 2025
LOCALLY ELEVATED FIRE WEATHER CONDITIONS WILL PERSIST THROUGH
THE EVENING HOURS. TAKING A LOOK AT THE LATEST OBSERVATIONS, RH
VALUES ARE HOVERING BETWEEN 28-35 PERCENT ACROSS MOST AREAS WITH
BREEZY WESTERLY WINDS BETWEEN 20-30 MPH. WHILE THIS COMBINED
WITH THE MILDER TEMPERATURES COULD LEAD TO A FEW HOURS OF RED
FLAG-LIKE CONDITIONS THIS AFTERNOON, THE WINDOW FOR THESE
CONDITIONS WILL BE LIMITED. AS A RESULT, WILL NOT ISSUE A FIRE
WEATHER HEADLINE THIS FOR THIS PERIOD. WITH ALL THIS IN MIND,
MAKE SURE TO LIMIT ANY ACTIVITY THAT COULD CREATE A SPARK!
LOOKING INTO FRIDAY, A WELL-MIXED ENVIRONMENT ALONG WILL THE
PASSAGE OF MULTIPLE COLD FRONTS WILL RESULT IN MUCH STRONGER
NORTHWESTERLY WINDS WITH GUSTS BETWEEN 40-50 MPH AT TIMES. WITH
LOWER DEW POINTS BEHIND THE COLD FRONTS, EXPECT RH VALUES TO
VARY SOMEWHERE BETWEEN 30-40 PERCENT SOUTH OF I-90 AND 50-60
PERCENT NORTH OF I-90. WHILE RELATIVE HUMIDITY VALUES WILL BE A
BIT MORE BORDERLINE SOUTH OF I-90, THERE COULD BE A NARROW
CORRIDOR ALONG THE MISSOURI RIVER VALLEY AND HWY-20 CORRIDORS
THAT TRUE RED FLAG WARNING CONDITIONS WILL BE POSSIBLE. HOWEVER,
WITH SOME LINGERING UNCERTAINTY REGARDING RH VALUES AND FALLING
TEMPERATURES BEHIND THE COLD FRONTS; DECIDED TO PUT THE OUTLINED
AREAS IN A FIRE WEATHER WATCH INSTEAD OF A WARNING AT THIS
TIME. EITHER WAY, WITH VERY HIGH TO EXTREME FIRE DANGER EXPECTED
BY FRIDAY AFTERNOON MAKE SURE TO FOLLOW YOUR LOCAL BURNING
RESTRICTIONS!
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.
