.DISCUSSION...Hot and dry conditions continue through at least
Thursday before monsoonal moisture returns to the region on

Thursday in western Arizona, then increasing storm chances and
coverage further north and west Friday. Uncertainty in
thunderstorm chances and coverage this weekend as dry air moves
back into the region this weekend.. Diurnal wind pattern expected
each day with afternoon wind gusts in the 15-25 mph range.
Note: Thunderstorms imply gusty and erratic winds.
