DISCUSSION
WINDS THIS MORNING WILL BE VARIABLE IN WIND DIRECTION AND AROUND 5
MPH. YOU SHOULD START TO SEE WINDS BEGINNING TO BECOME
SOUTHEASTERLY BY 10-11 AM THIS MORNING AND ONCE THEY SETTLE ON SE,
IT WILL GENERALLY REMAIN FROM THE SOUTHEAST TO SOUTH THROUGH THE
DAY. WIND SPEEDS WILL PICK UP AS WELL BY AFTERNOON AND THE
BURNSITE IS RIGHT ON THE EDGE OF WHERE THE HIGHER WINDS WILL BE IN
EASTERN NORTH DAKOTA. SPEEDS SHOULD GENERALLY RANGE BETWEEN 15-20
MPH SUSTAINED WITH GUSTS APPROACHING 25-30 MPH AT TIMES, BUT THOSE
HIGHER THRESHOLDS ARE MORE LIKELY TO BE CONFINED TO NORTH DAKOTA.
RELATIVE HUMIDITY TODAY IS A BIT UNCERTAIN THANKS TO THE RECENT
RAINS WE HAD. BECAUSE OF THE RECENT RAIN, THERE ISN'T AN
EXPECTATION AT THIS POINT FOR SIGNIFICANT MIXING BRINGING RH DOWN
TO THE 20S, SO THE CURRENT THINKING IS THE REASONABLE LOWEST WILL
BE IN THE LOW 30S. THE MOST LIKELY MINIMUM RELATIVE HUMIDITY THIS
AFTERNOON IS ROUGHLY 33-37%. RECOVERY TONIGHT WILL DEPEND ON
OVERNIGHT TEMPERATURES BUT WILL RISE TO ABOVE 60% BY MIDNIGHT.
WINDS REMAIN ELEVATED THROUGH TOMORROW WITH ONLY SMALL VARIANCES
IN WIND DIRECTION CHANGE.
