.DISCUSSION...

...RED FLAG WARNING IN EFFECT UNTIL 6 AM THURSDAY...

EXPECT THUNDERSTORMS PRODUCING GUSTY WINDS TO IMPACT THE FIRE
THROUGHOUT THE DAY. STORMS WILL BE CAPABLE OF WIND GUSTS TO 50
MPH. THE THUNDERSTORMS OVER THE FIRE THIS MORNING MAY DECREASE FOR
A WHILE BUT WILL INCREASE AGAIN THIS AFTERNOON. EXPECT A PERIOD OF
BETTER SUNSHINE EARLY AFTERNOON WHICH WILL ALLOW DRIER AIR TO MIX
DOWN ON THE FIRE AND CAUSE WINDY CONDITIONS ON EXPOSED AREAS. A
STRONG COLD FRONT MOVING THROUGH THE REGION WILL SWITCH WINDS TO
NORTH BY THIS EVENING AND WILL CAUSE STRONGER DOWN VALLEY FLOWS
THAN THE SITE HAS SEEN FOR A WHILE. IT WILL BE COOLER THURSDAY
WITH MUCH HIGHER HUMIDITY AND A BETTER CHANCE FOR A WETTING RAIN
ON THE FIRE. BORSUM
