.DISCUSSION...
Dry weather will continue through the day Tuesday with minimum
humidity values falling into the low 30% range. Locally efficient
mixing could result in pockets of slightly lower values in the
25-30% range. Winds at lower elevations are expected to remain
light between 5-10 mph, but higher winds and gusts can be expected
along ridges. At least scattered showers are expected across the
mountains Tuesday night between 1-6am with humidity values
recovering into the upper 80% range. Rainfall amounts will
generally be light and less than 0.1", but locally higher amounts
up to 0.25" cannot be ruled out where any heavier showers track.
