RANGELAND FIRE DANGER STATEMENT
NATIONAL WEATHER SERVICE SIOUX FALLS SD
318 AM CDT TUE MAY 12 2026
DISCUSSION
A COMBINATION OF MILD TEMPERATURES, WIND GUSTS TO 40 MPH AND
AFTERNOON RELATIVE HUMIDITY BELOW 25 PERCENT WILL CREATE CRITICAL
FIRE WEATHER CONDITIONS FOR THE AREA. WHILE WEDNESDAY WILL BRING
A REPRIEVE FROM THE STRONG WINDS, THURSDAY WILL SEE SOUTHERLY
WINDS RETURN WITH GUSTS AS HIGH AS 45 MPH. THIS MAY LEAD TO
ANOTHER DAY OF CRITICAL TO NEAR CRITICAL FIRE WEATHER. ONE
OFFSETTING FACTOR FOR THURSDAY WILL BE THE POTENTIAL FOR CLOUDS
AND SCATTERED SHOWERS AND ISOLATED THUNDERSTORMS. WHILE VERY RARE IN
THIS AREA, THERE IS AT LEAST A SMALL CHANCE FOR SOME DRY LIGHTNING
GIVEN THE DRY LOW LEVELS ON THURSDAY. THE WEEKEND, PARTICULARLY
SATURDAY NIGHT INTO SUNDAY, WILL SEE THE NEXT BETTER CHANCE
FOR SHOWERS AND THUNDERSTORMS.
