DISCUSSION
DRY WEATHER PERSISTS FOR THE NEXT FEW DAYS AS RAIN IS NOT EXPECTED FOR
THE REST OF THE WORK WEEK. MINIMUM RELATIVE HUMIDITY VALUES WILL LIKELY
BE IN THE 20-30% RANGE THURSDAY AND FRIDAY AFTERNOON. WINDS OVERALL WILL BE
LIGHT AND AT SOME POINT CALM AS LOCALIZED HIGHER PRESSURE WEDGED INTO THE
MOUNTAINS REMAIN. THIS WILL RESULT IN POOR SMOKE DISPERSAL AND MIXING CONDITIONS
TONIGHT THROUGH AT LEAST FRIDAY. NEXT BEST CHANCE OF PRECIPITATION WILL NOT
BE UNTIL SATURDAY BUT EVEN THEN THE CHANCE IS VERY LOW (15-20% CHANCE).
