RANGELAND FIRE DANGER STATEMENT
NATIONAL WEATHER SERVICE ABERDEEN SD
243 AM CDT WED APR 22 2026
DISCUSSION
SOUTHEASTERLY WINDS WILL BECOME MORE SOUTHERLY THROUGH THE DAY
AS THEY GUST UP TO 35 TO 45 MPH THIS AFTERNOON. MINIMUM RELATIVE
HUMIDITY VALUES WILL DROP DOWN BETWEEN 20 TO 30 PERCENT OVER
NORTHEASTERN SD AND WEST CENTRAL MN AND BETWEEN 15 TO 20 PERCENT
OVER CENTRAL SD. WITH THE WINDY AND DRY CONDITIONS, A RED FLAG
WARNING HAS BEEN ISSUED OVER CENTRAL AND NORTHEASTERN SD AND WEST
CENTRAL MN. WITH THE HIGH FIRE WEATHER CONCERNS, MAKE SURE TO KEEP
AN EYE ON ANY RECENT BURNS TO ENSURE THEY ARE FULLY EXTINGUISHED.
ADDITIONALLY, BE CAUTIOUS OF ANYTHING THAT COULD CREATE A SPARK OR
FIRE, SUCH AS FARM EQUIPMENT, CHAINS ON VEHICLES AND TRAILERS, AND
AVOID IMPROPER DISPOSAL OF CIGARETTES. IF A FIRE WERE TO IGNITE, IT
COULD BECOME DIFFICULT TO CONTROL OR SUPPRESS.
THERE IS THE POTENTIAL FOR THUNDERSTORM AND RAIN DEVELOPMENT MAINLY
OVER CENTRAL SD THIS EVENING AND OVERNIGHT AS A COLD FRONT MOVES
THROUGH. THERE IS A MARGINAL RISK FOR THESE STORMS TO BECOME SEVERE,
WITH THE PRIMARY THREAT OF WIND GUSTS OVER 60 MPH. ADDITIONALLY, DUE
TO THE DRY NATURE OF THE ATMOSPHERE, THE STORMS HAVE A POTENTIAL TO
PRODUCE A MICROBURST OR TWO, WHICH IS ANOTHER WIND HAZARD. AS THE
COLD FRONT AND PRECIPITATION CHACNES MOVE EAST THROUGH THE NIGHT,
THE WINDS WILL SHIFT TO BE MORE SOUTHWESTERLY AND WESTERLY. STRONG
WINDS WILL THEN MOVE INTO CENTRAL SD THURSDAY WITH GUSTS UP AROUND 45
MPH POSSIBLE. RELATIVE HUMIDITY DOES RECOVER INTO THURSDAY, WITH IT
BEING ABOVE 25 TO 30 PERCENT OVER MOST OF CENTRAL AND NORTHEASTERN SD
DURING THE AFTERNOON.
