.DISCUSSION...
SOUTHEASTERLY WINDS WILL INCREASE TO 20 TO 25 MPH WITH GUSTS OF 30
TO 35 MPH THROUGH SOUTH CENTRAL SOUTH DAKOTA AND THE JAMES RIVER
VALLEY TODAY. THIS IN COMBINATION WITH AFTERNOON RELATIVE HUMIDITY
OF AROUND 25 PERCENT WILL RESULT IN A VERY HIGH FIRE DANGER ACROSS
THAT AREA. WITH RH VALUES BEING MARGINAL...HELD OFF ON ISSUING A RED
FLAG WARNING...HOWEVER...IF DEW POINTS DROP LOWER THAN EXPECTED OR
TEMPERATURES WARM MORE THAN EXPECTED...FUTURE SHIFT MAY HAVE TO RE
EVALUATE.

WINDY CONDITIONS WILL CONTINUE ACROSS THE REGION WEDNESDAY...THOUGH
INCREASING LOW LEVEL MOISTURE AHEAD OF AN APPROACHING FRONT SHOULD
KEEP HUMIDITY LEVELS IN CHECK...WITH MINIMUM AFTERNOON HUMIDITY
LEVELS RANGING FROM 30 TO 40 PERCENT IN THE LOWER BRULE AREA...TO 50
PERCENT OR HIGHER IN SOUTHWEST MINNESOTA AND THE IOWA GREAT LAKES.
DESPITE THE HIGHER HUMIDITY LEVELS...FIRE DANGER WILL STILL BE HIGH
TO VERY HIGH DUE TO THE STRONG WINDS.

FIRE DANGER CONCERNS INCREASE AGAIN ON THURSDAY HOWEVER...WITH LOW
LEVEL DRYING AND GUSTY WESTERLY WINDS DEVELOPING BEHIND THE DEPARTING
FRONT. THE AREA OF GREATEST CONCERN WOULD BE FROM THE LOWER BRULE
INTO THE JAMES RIVER VALLEY AND LOWER BIG SIOUX RIVER VALLEY. THESE
AREAS WILL SEE THE STRONGEST AFTERNOON WINDS IN THE 20 TO 30 MPH
RANGE...ALONG WITH THE POTENTIAL FOR MINIMUM HUMIDITY LEVELS OF 15 TO
25 PERCENT. WILL NOT ISSUE ANY FIRE WEATHER HEADLINES AT THIS TIME...
BUT THE FORECAST FOR THESE AREAS WILL HAVE TO BE MONITORED CLOSELY
OVER THE NEXT COUPLE OF DAYS.

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