.DISCUSSION...
A STRONG LATE SUMMER COLD FRONT WILL MOVE QUICKLY THROUGH THE IDAHO
PANHANDLE THIS AFTERNOON BRINGING SOME OF THE GUSTIEST WINDS TO THE
WILDFIRE AREA THAT WE HAVE SEEN IN SEVERAL WEEKS. THE COMBINATION
OF STRONG WIND AND CRITICALLY LOW RELATIVE HUMIDITY WILL CONTRIBUTE
TO THE POTENTIAL FOR EXTREME FIRE BEHAVIOR. WINDS WILL DIMINISH
OVERNIGHT AS MUCH COOLER AIR ARRIVES OVERNIGHT. FRIDAY THROUGH
EARLY NEXT WEEK WILL BE MUCH COOLER THAN AVERAGE WITH SLIGHT CHANCES
OF LIGHT RAIN SHOWERS.
