Forecast Discussion: FIRE SAFETY BURN BANS OR RESTRICTIONS ARE IN EFFECT FOR MOST AREAS OF NORTH IDAHO. CONTACT YOUR LOCAL FIRE PROTECTION DISTRICT PRIOR TO CONDUCTING ANY OUTDOOR OPEN BURNING. Smoke from wildfires in and around the western U.S. and Canada can move into the area and degrade air quality quickly. Be aware of changing conditions to protect your health. A cold front will begin to influence the area on Friday resulting in gusty winds in the afternoon. Air quality is forecast to range from UNHEALTHY for SENSITIVE GROUPS to the UNHEALTHY range in north Idaho on Friday.
