DIURNAL, TERRAIN-DRIVEN WINDS WILL CONTINUE FOR INTERIOR
DEL NORTE COUNTY THROUGH THURSDAY. AMPLE RH RECOVERIES ARE EXPECTED WITH
LOW DAYTIME RH VALUES REMAINING BETWEEN 20-30%. AN INCOMING SURFACE LOW
PRESSURE CENTER FLOWING TO THE SOUTH OF OUR AREA COULD FUNNEL MOISTURE INTO
THE BURN AREA POSSIBLE CREATING RAIN SHOWERS, YET FORECAST CONFIDENCE REMAINS
LOW ON DETAILS FOR THIS RAIN AS A SHORT CHANGE IN THE LOW CENTERS POSITION
MID-WEEK DRASTICALLY CHANGES ITS IMPACTS FOR THE BURN AREA. MIXING HEIGHTS
HOWEVER LOOK TO BE SLIGHTLY LOW THAN THE SURROUNDING MOUNTAINS FROM THE BURN
SITE WHICH COULD INCREASE THE LIKELIHOOD OF SMOKE BECOMING TRAPPED IN THE
VALLEY DUE TO LIGHT WINDS AND MINIMAL ATMOSPHERIC MIXING. HOWEVER, THE SMOKE
SHOULD REMAIN ELEVATED AS NIGHTTIME MIXING HEIGHTS REMAIN ELEVATED.
