AN ELONGATED AREA OF HIGH PRESSURE NOSES IN OVER NORTHWEST
COLORADO ON WEDNESDAY, KEEPING SKIES CLEAR AND CONDITIONS CALM. THIS WILL
LIMIT MIXING AND KEEP SMOKE DISPERSAL VALUES POOR THROUGH THE PERIOD.
STRONGER SOUTHWESTERLY WINDS ARE EXPECTED ON THURSDAY, IMPROVING VENTILATION
RATES SLIGHTLY, BUT POOR SMOKE DISPERSAL WILL PERSIST THROUGH THE END OF THE
WEEK. A SYSTEM MOVING IN SATURDAY WILL BRING THE NEXT CHANCE FOR IMPROVED
MIXING AND FAIR OR BETTER SMOKE DISPERSAL.
