RANGELAND FIRE DANGER STATEMENT
NATIONAL WEATHER SERVICE SIOUX FALLS SD
428 AM CDT THU APR 10 2014

.DISCUSSION...

WHILE TODAY WILL END UP ABOUT 15 DEGREES COOLER THAN
YESTERDAY...STRONG WINDS AND LOW AFTERNOON HUMIDITIES WILL LEAD TO
ANOTHER DAY OF POTENTIALLY DANGEROUS FIRE WEATHER. THE MOST AFFECTED
AREAS WILL BE SOUTHWEST MINNESOTA WHERE SUSTAINED WINDS OF ABOUT 20
TO 25 MPH WITH GUSTS AROUND 30 MPH WILL COMBINE WITH HUMIDITY VALUES
OF 20 TO 25 PERCENT TO CREATE RED FLAG CONDITIONS THIS AFTERNOON. A
BUFFER ZONE NEAR SOUTHWEST MINNESOTA...EXTREME EASTERN SOUTH DAKOTA
INTO FAR NORTHWEST IOWA WILL COME CLOSE TO HITTING RED FLAG CRITERIA
BUT BELIEVE WINDS WILL BE JUST LOW ENOUGH TO STAY IN THE VERY HIGH
CATEGORY. THESE AREAS WILL NEED TO BE MONITORED HOWEVER.

ANOTHER DAY OF VERY HIGH FIRE DANGER EXPECTED ON FRIDAY. DEEP MIXING
WILL RESULT IN AFTERNOON RELATIVE HUMIDITY VALUES DROPPING INTO THE
15 TO 25 PERCENT RANGE. AT THIS TIME...WINDS DO NOT APPEAR STRONG
ENOUGH TO WARRANT A RED FLAG WARNING...BUT IT WILL BE CLOSE. THUS
WILL NEED TO CONTINUE TO MONITOR THE SITUATION.

LIGHT RAIN AMOUNTS ARE POSSIBLE TONIGHT AND FRIDAY NIGHT IN SCATTERED
SHOWERS. SHOWERS AND THUNDERSTORMS LATER FRIDAY NIGHT INTO SATURDAY
MAY DROP HIGHER AMOUNTS OF RAIN...WITH THE BEST CHANCE OF THIS ALONG
AND SOUTHEAST OF A SIOUX CITY TO JACKSON LINE.

CONSIDER POSTPONING BURNING DUE TO THE VERY HIGH OR EXTREME FIRE
DANGER.
