.DISCUSSION...
IT WILL BE A WARM AND DRY DAY OVER THE BURN SITE AS UPPER LEVEL
HIGH PRESSURE SHIFTS ACROSS THE AREA. PRESSURE GRADIENTS WILL
SUPPORT SOUTHERLY RIDGETOP WINDS BUT THE LESS EXPOSED PARTS OF THE
UNIT WILL SEE UPVALLEY WINDS. THE HIGHER END OF THE UNIT COULD SEE
MORE OF A WESTERLY WIND THIS AFTERNOON DUE TO THE COMBINATION OF
UPVALLEY AGAINST THE RIDGETOP FLOW. LOW PRESSURE OVER NORTH
CENTRAL MONTANA TONIGHT THIS WILL SUPPORT DOWNVALLEY FLOWS. THE
SURFACE LOW PRESSURE IS EXPECTED TO SHIFT EAST ON SUNDAY BRINGING
A WEAK COLD FRONT DURING THE AFTERNOON WHICH WILL SUPPORT STRONGER
UPVALLEY WINDS. AHEAD OF THE FRONT ON SUNDAY IT WILL AGAIN BE WARM
AND DRY. THERE IS A SLIGHT CHANCE FOR MOISTURE BEHIND THE FRONT
BUT IT IS NOT EXPECTED UNTIL SUNDAY EVENING. BORSUM
