DISCUSSION
A SYSTEM WILL BRING WINDY CONDITIONS THROUGHOUT THE AREA TODAY,
BUT MINIMUM HUMIDITIES BETWEEN 35-45% SHOULD LIMIT THE FIRE
DANGER. SOUTHERLY WINDS WILL BE SUSTAINED AROUND 20-30 MPH, WITH
GUST UPWARDS TO 40 MPH TODAY. TONIGHT AND THROUGH FRIDAY MORNING,
WE WILL SEE A FEW ROUNDS OF SHOWERS AND STORMS WORK THROUGH THE
AREA, FURTHER REDUCING ANY FIRE THREAT.
THE GRASSLAND FIRE DANGER INDEX -GFDI- DOES NOT ACCOUNT FOR
PRECIPITATION THAT OCCURS OR ANY SNOW ON THE GROUND. PLEASE
MAKE APPROPRIATE ADJUSTMENTS.
