DISCUSSION
NORTHWEST WINDS WILL BE INCREASING EARLY THIS AFTERNOON WITH
GUSTS 25 TO 30 MPH EXPECTED FROM PROPOSED IGNITION TIME THROUGH
SUNSET. WHILE THIS WILL PROVIDE EXCELLENT SMOKE DISPERSAL, THE
WIND DIRECTION MAY BE A BIT ERRATIC WITH THE GUSTS WHICH COULD
LEAD TO CHALLENGES IN DIRECTION OF FIRE SPREAD. A FEW SPRINKLES
WILL ALSO BE POSSIBLE, WHICH COULD FURTHER IMPACT WINDS WITH
BRIEF HIGHER GUSTS AT TIMES.
LIGHTER WINDS ARE EXPECTED ON WEDNESDAY, BUT TEMPERATURES WILL BE
COOLER, HUMIDITY LEVELS HIGHER, AND THERE IS A CHANCE OF LIGHT
SNOW DEVELOPING BY EARLY-MID AFTERNOON.
