UPDATE 2:00 p.m.


As Boise's temperature topped 100 degrees, Idaho's Department of Environmental Quality pushed its air quality alert to an "orange" status, indicating an unhealthy ozone layer.

The DEQ said children and people with asthma were at particular risk.


ORIGINAL POST 9:00 a.m.


Boiseans woke up to a hot, steaming cup of smoke this morning, as southerly winds pushed warm smoke into the Treasure Valley, accumulating from a series of wildfires that have defined southern Idaho this week.

Additionally, elevated ozone levels are expected to blanket the Treasure Valley today with yet another yellow air quality alert in effect. In fact, the air quality index is 90, just south of a 100 reading, which would push the alert to orange. A yellow air alert bans all open burning and fireplace usage in Ada County.

The National Weather Service office in Boise is forecasting patchy smoke to continue until early afternoon, and then the heat begins its climb up to triple digits. An upper level trough and monsoonal moisture is expected to push through the region this evening, bringing thunderstorms and lightning.

A red flag warning remains in effect for much of southern Idaho.
