.DISCUSSION...
Below normal temperatures will persist for the next several days
as a broad area of low pressure remains fixed over the western
U.S. Very little in the way of precipitation is expected through
Friday, with exception to a few very light showers over the White
Mountains and higher terrain east of Tucson. The dry air mass will
support humidity values falling as low as the upper teens across
the lowest elevations during peak heating, despite the cool air
mass. Winds will generally remain below 10 mph each day, although
a few afternoon breezes are possible A chance for rain will
return Friday into Saturday morning in association with another
weak storm system.
