PERCENT RANGE TODAY AND INTO THE UPPER 20 TO LOWER 30 PERCENT
RANGE ON WEDNESDAY. HOWEVER, 20 FOOT WINDS WILL REMAIN BELOW 10
MPH DURING THIS TIME. ADDITIONALLY, MIXING HEIGHTS WILL TOP OUT
BETWEEN 5500-8000 FEET TODAY AND BETWEEN 6600-10500 FEET ON
WEDNESDAY. SOUTHWEST TRANSPORT WINDS BETWEEN 10-15 MPH TODAY WILL

FORECAST TO BE GOOD TO VERY GOOD TODAY AND VERY GOOD ON WEDNESDAY.
FOG POTENTIAL OVER THE NEXT FEW DAYS: THERE IS A LOW CHANCE OF
PATCHY FOG EARLY THIS MORNING, ESPECIALLY FOR SHELTERED LOCATIONS
AND NEAR BODIES OF WATER.
POTENTIAL FOR RED FLAG CONDITIONS: WHILE MINIMUM RELATIVE
HUMIDITY VALUES WILL BE LOW THROUGH MIDWEEK, WINDS ARE FORECAST TO
BE BELOW 10 MPH. THEREFORE, RED FLAG CONDITIONS ARE NOT
ANTICIPATED AT THIS TIME. ALTHOUGH, FUELS ARE DRY, SO THERE WILL
AT LEAST BE AN INCREASED FIRE DANGER CONCERN THROUGH MIDWEEK.
