Thursday with widespread critical fire weather conditions 
developing. Wetting rains are not expected. Cooler temperatures

critical fire weather conditions Friday and Saturday. Additional 
moisture by early next week could suppress critical fire weather 
conditions and introduce non zero precipitation chances to the
