DISCUSSION
A COLD FRONT IS PUSHING THROUGH THE AREA THIS MORNING, RESULTING IN
LIGHT RAIN SHOWERS AND GUSTY WINDS. COVERAGE IN THE LIGHT SHOWERS
WILL WANE THROUGH THE MORNING HOURS ALONG WITH SLOWLY DECREASING
WINDS WHILE WIND DIRECTION TURNS WESTERLY. THE LOWEST HUMIDITY
VALUES WILL COME JUST BEHIND THE FRONT THIS AFTERNOON AS HIGH
TEMPERATURES WARM TO THE MID 60S TO LOW 80S FROM NORTHWEST TO
SOUTHEAST. THE LOWEST HUMIDITY VALUES WILL LIE ALONG AND SOUTHEAST
OF A MARSHALL, MINNESOTA TO SIOUX FALLS, SOUTH DAKOTA, TO YANKTON,
SOUTH DAKOTA LINE WHERE HUMIDITY VALUES WILL FALL TO AROUND 30%. AT
THE SAME TIME, THIS IS ALSO THE SAME AREA WHERE WINDS WILL BE
WEAKEST WITH GUSTS WEAKENING TO JUST ABOUT 25 MPH. THUS, SOME
ELEVATED FIRE DANGER IS POSSIBLE WITH FIRE DANGER CAPPING OUT AT
HIGH ACROSS MAINLY NORTHWEST IOWA.
LOW FIRE DANGER IS EXPECTED FOR MONDAY AND TUESDAY BUT COULD SEE
ELEVATED FIRE DANGER MAKE A COMEBACK ON WEDNESDAY. HIGHS WILL WARM
TO THE UPPER 60S AND 70S WITH DEW POINTS FALLING TO THE UPPER 30S
AND 40S. THIS WILL RESULT IN HUMIDITY VALUES DOWN TO 30-50%. WINDS
