.DISCUSSION...
PATCHY LOW CLOUDS OR FOG NEAR THE BURN SITE WILL BURN OFF
BY 1000. EXPECT LESS AFTERNOON CLOUD COVER TODAY AS SURFACE HIGH
PRESSURE MOVES SOUTHWARD THROUGH THE DAKOTAS. SURFACE WINDS WILL
BE SOUTHEASTERLY TODAY WHICH WILL KEEP HUMIDITY VALUES NEAR 30
PERCENT. MOSTLY CLEAR SKIES AROUND MIDDAY WILL GIVE WAY TO SOME
HIGH LEVEL CLOUDS MOVING IN FROM THE SOUTH LATER THIS AFTERNOON.
TONIGHT SHOULD HAVE EXCELLENT RECOVERIES BEFORE WINDS SWITCH TO
SOUTHERLY THURSDAY MORNING. THIS WILL SUPPORT MUCH WARMER
TEMPERATURES WITH LOWER HUMIDITY. BORSUM
