.DISCUSSION...Fire weather concerns will remain low the next few
days as monsoonal moisture lingers over the area and keeps 
afternoon humidity up. A change arrives by Tuesday as the 
moisture plume is swept to the East and much drier air moves into 
the region. By mid to late week afternoon humidity will be in the 
teens to single digits. Warm conditions by this time will help 
bring some gusty afternoon conditions and critical fire weather 
conditions may become more probable where fuels are ready to burn.
