DISCUSSION
DRY WEATHER WILL PERSIST THROUGH MIDWEEK. MINIMUM RELATIVE
HUMIDITY VALUES ARE EXPECTED TO BE IN THE UPPER 20 TO LOWER 30
PERCENT RANGE BOTH TODAY AND 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 DECREASE SLIGHTLY ON WEDNESDAY. LASTLY,
DAYTIME DISPERSIONS ARE 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.
