.DISCUSSION...

HIGH PRESSURE CENTERED OVER THE MN/WI BORDER THIS MORNING HAS RESULTED
IN A FROSTY START TO THE DAY AT THE BURN SITE WITH CALM WINDS. THERE IS
A COLD FRONT WORKING ACROSS THE DAKOTAS THIS MORNING AND WILL BE
ENTERING WESTERN MN THIS AFTERNOON. THIS FRONT WILL BE FAR ENOUGH FROM
THE BURN AREA TO KEEP THE WINDS AT 5 MPH OR LESS UNTIL THE LATE
AFTERNOON...WHEN THE SOUTHERLY WINDS WILL BE UP NEAR 10 MPH. THIS FRONT
IS RATHER DRY...SO NO PRECIPITATION AND LITTLE CLOUD COVER IS EXPECTED
WITH IT. WITH THE RETURN TO LIGHT SOUTHERLY WINDS AND MOSTLY SUNNY SKIES...
TEMPERATURES WILL BE ABOUT 10 DEGREES WARMER THAN YESTERDAY...WITH HIGHS
GETTING NEAR 60. THIS WILL ALLOW AFTERNOON HUMIDITIES TO DROP DOWN TO
AROUND 25 PERCENT. THE FRONT AND ITS WIND SHIFT TO THE WEST IN NOT EXPECTED
TO MOVE ACROSS THE BURN SITE UNTIL LATE TONIGHT.
