Unseasonably warm, dry and windy conditions will bring critical fire weather to parts of the forecast area where vegetation has been reported dry and susceptible to rapid fire spread from land management agencies. These conditions will occur this afternoon into early evening, and again Wednesday ahead of a cool front expected in the evening. The highest threat on Wednesday will be over South Park and Lincoln county.


From Chris Tomer:
Where's the smoke coming from? A strong southwest wind is carrying smoke across Colorado from SW CO and AZ. The Magnum Fire in AZ is 29,500acres.
