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.
