.DISCUSSION...
THE BURN AREA WILL BE BETWEEN SYSTEMS TODAY WITH HIGH PRESSURE TO THE
NORTH AND LOW PRESSURE OVER SOUTHEAST NEBRASKA. AFTER STARTING THE DAY
WITH FAIRLY LIGHT WINDS...NORTH TO NORTHEAST WINDS ARE EXPECTED FOR
THE REST OF THE DAY. SOME HIGH THIN CIRRUS WILL GIVE WAY TO MORE SUN
FOR THE AFTERNOON. AS THE PAST SEVERAL DAYS HAVE BEEN...THE NEXT COUPLE
DAYS WILL ONCE AGAIN HAVE GOOD AFTERNOON MIXING TO DRAW DOWN DRY AIR
FROM ALOFT. ANTICIPATE DRY RELATIVE HUMIDITY...PARTICULARLY ACROSS THE
WOODED AREAS OF MINNESOTA. WOULD NOT BE SURPRISED OF LOCALIZED BETTER
MIXING...SO RH VALUES COULD END UP BEING 5 TO 10 PERCENT LOWER THAN THE
FORECAST.
