DISCUSSION
WARM AND DRY CONDITIONS ARE EXPECTED OVER THE FIRE SITE TODAY.
WITH THIS, SOUTH TO SOUTHEASTERLY WINDS WITH OCCASIONAL GUSTS TO
15 MPH DURING THE AFTERNOON ARE FORECAST. LATE TONIGHT INTO
TUESDAY, THE THREAT OF GUSTY AND ERRATIC MOUNTAIN WAVE WINDS
INCREASES OVER THE FIRE SITE. WHILE UNCERTAINTY REMAINS ON THE
POTENTIAL STRENGTH AND TIMING OF THESE WINDS, SOUTHWESTERLY GUSTS
OF 30 TO 50 MPH COULD OCCUR (MODERATE CHANCE). BREEZY RIDGETOP
WINDS WILL ALSO KEEP THE FIRE ACTIVE OVERNIGHT. A COLD FRONT
PASSAGE MID-DAY TUESDAY WILL THEN SHIFT WINDS OUT OF THE
NORTHWEST, WITH GUSTS AGAIN IN THE 30 TO 50 MPH RANGE POSSIBLE.
ISOLATED RAIN/SNOW SHOWERS LOOK TO ACCOMPANY THE FRONT TUESDAY AS
WELL, BUT THE WIND REMAINS THE BIGGEST THREAT.
