NORTHEASTERN SD OVERNIGHT, THE WINDS HAVE BEEN SHIFTING TO BECOME
MORE WESTERLY. THESE WINDS WILL BE PICKING UP THROUGH THE DAY, WITH
SUSTAINED WINDS OF 25 TO 35 MPH AND GUST UP TO 45 TO 50 MPH EXPECTED
OVER CENTRAL SOUTH DAKOTA THROUGH THE AFTERNOON. NORTHEAST SOUTH
DAKOTA WILL BE A BIT WEAKER, BUT THE WINDS WILL STILL BE GUSTING UP
TO 40 MPH. THE RELATIVE HUMIDITY VALUES OVER THE NORTHEAST WILL DROP
BELOW 25 PERCENT TODAY LEADING TO A RED FLAG WARNING BEING ISSUED
FOR THIS AFTERNOON. CENTRAL SOUTH DAKOTA WILL SEE HUMIDITY VALUES
BETWEEN 20 TO 35 PERCENT, WHICH REDUCES THE FIRE WEATHER CONCERNS
SLIGHTLY. HOWEVER, WITH THE STRONG WINDS, ANY FIRE THAT DOES IGNITE
OR REIGNITES COULD BECOME DIFFICULT TO SUPPRESS OR CONTROL.
