.DISCUSSION...
HIGH PRESSURE IS LOCATED OVER NORTH CENTRAL MINNESOTA THIS MORNING.
THIS IS RESULTING IN FAIRLY LIGHT WINDS AND THE COOL START. AS THIS
HIGH SLOWLY MOVES OFF TO THE EAST TODAY...SOUTH/SOUTHEAST WINDS
WILL SLOWLY BECOME ESTABLISHED. HOWEVER...THIS COULD TAKE QUITE A WHILE
AND COULD LEAD TO ERRATIC/LIGHT WINDS THROUGH EARLY AFTERNOON. AS FAR
AS TEMPERATURES GO...AFTER THE COOL START TEMPERATURES ARE QUICKLY
RISING. DEW POINTS WERE VERY DRY YESTERDAY AND SHOULD BE A LITTLE HIGHER
TODAY. EVEN SO...AFTERNOON HUMIDITY LEVELS ARE EXPECTED TO DRY OUT TO
THE MID 20 PERCENT RANGE. LOTS OF RAIN IN THE FORECAST BY LATER TONIGHT
AND CONTINUING THROUGH MONDAY NIGHT.
