LIGHT WINDS, AND MINIMUM RH VALUES >40%. TUESDAY WILL BE SLIGHTLY
WARMER AND DRIER WITH MINIMUM RH VALUES >30%, HOWEVER WINDS REMAIN
LIGHT. ELEVATED FIRE DANGER IS POSSIBLE WEDNESDAY AS SOUTHERLY
WINDS INCREASE TO 20-25 MPH AND MINIMUM RH VALUES FALL TO AROUND
30% FOR SOUTHWESTERN MINNESOTA AND NORTHWESTERN IOWA. THE
STRONGEST WINDS WILL BE LOCATED OVER CENTRAL SOUTH DAKOTA,
DISPLACED FROM THE LOWEST RH VALUES.
