.DISCUSSION...
High pressure will continue over the Four Corners region through the 
week allowing for mostly clear skies and dry weather each day. Surface
winds will remain light with strong inversions each night, resulting
in less than ideal burning conditions through the week. By Friday, a 
new storm system will increase winds in the afternoon with some isolated
showers returning to the region in the afternoon and into Saturday.
