DISCUSSION
MID LEVEL MONSOONAL MOISTURE AND INSTABILITY WILL BRING A
20 PERCENT CHANCE OF SHOWERS AND THUNDERSTORMS TO THE FIRE
LOCATION TODAY AND TONIGHT, INCREASING TO 30 PERCENT ON
MONDAY. STRONG AND ERRATIC OUTFLOW WIND GUSTS UP TO 40 MPH
WILL BE POSSIBLE NEAR ANY THUNDERSTORMS. IN ADDITION, THE
LOWER LEVELS OF THE ATMOSPHERE ARE STILL QUITE DRY TODAY

STRIKES, WITH STORMS LIKELY TURNING WETTER ON MONDAY.
WITH HIGHER MIXING HEIGHTS TODAY AND MONDAY (UP TO 13,000 FEET),
THERE WILL BE AN INCREASED RISK OF LARGE PLUME DOMINATED FIRE BEHAVIOR.
