.DISCUSSION...Expect daily chances for rain showers and
thunderstorms into the new week. Dryer air will be moving into the
region to create day to day variability of intensity and
coverage. Temperatures will be running above normal through the
weekend with an Extreme Heat Warning in effect through Friday in
the lower elevations. Winds will generally remain less than 15 mph
with the afternoon gustiness into the new week. Min RHs will be
15-20 percent in the low elevations and 20-30 in the mountains
through the weekend. Deep monsoon moisture will return early next
week to provide higher wetting rain chances and coverage as well
as better min RHs and below normal temperatures.
