.DISCUSSION...
PRIMARY CONCERN FOR THE PRESCRIBED BURN TODAY WILL BE WINDS AND LOW
HUMIDITY. ENHANCED EAST TO SOUTHEAST DOWNSLOPE WINDS EXPECTED THIS
MORNING AT THE BURNSITE DUE TO A TIGHTER EASTERLY PRESSURE GRADIENT
ALONG THE WESTERN SIERRA SLOPES. MODERATE WINDS WILL CONTRIBUTE TO
VERY LOW RH VALUES THIS AFTERNOON. WINDS WILL BECOME LIGHT LATER
THIS AFTERNOON/EVENING BUT OVERNIGHT RECOVERIES WILL BE POOR TO
MODERATE...THUS THE DRY CONDITIONS WILL CONTINUE INTO THURSDAY.
HUMIDITIES WILL IMPROVE THURSDAY EVENING ONWARD AS WINDS REMAIN
LIGHT AND A MILD WEATHER PATTERN PERSISTS.
