.KEY MESSAGES...

* Hazardous heat builds today, likely lasting into the next work
  week week.

* Monsoon conditions return in the middle of next week.

.DISCUSSION...through Wednesday.

Extreme Heat Warnings and Heat Advisories have gone into effect as
heat returns to dangerous levels. Temperatures will build over the
next few days and peak over the weekend, approaching daily and
monthly temperature records. Overnight cooling will be very
limited with lows building into the 80s and 90s for most of the
lower elevations. Expect major to extreme heat risk to last
through the weekend and into the next week. Confidence is high
that the current heat hazards will be extended beyond monday.


The pattern chances slightly in into the first week of August,
leading to some slight cooling followed by a push of monsoonal
moisture by the mid-week. This will offer increased humidities
and chances for storms, with the best chances affecting Mohave Co
AZ. The longer term models are in good agreement for these storm
chances, but the timing has been shifting between model updates,
tending slightly earlier.
