.DISCUSSION...Through Tuesday

Overnight lows look to be very similar to the previous night with
only a few degrees warmer for a few sites, continuing the pattern
of near record-breaking warm mornings. This warm morning will lead
into another warm afternoon with temperatures very comparable to
Wednesday afternoon, with most sites seeing only a degree plus or
minus from the previous day`s high. These highs will mostly be
around 5 degrees above average, and lead to Moderate to Major
HeatRisk in most desert valleys and the Extreme Heat Warning
remains in effect through Friday. Slight relief is for Friday as
afternoon highs fall by a few degrees, but Saturday shows a slight
rebound. Slight cooling is expected again Sunday, but from there
highs and lows look to plateau into the next work week with
fairly consistent heat expected.

Thunderstorms return to the forecast late Thursday morning as
moisture advects across most of Arizona and into portions of of
Nevada and SE California. The best chances for storms will be
focused over Mohave Co offering locally heavy rain and strong
gusts as well as flooding and lightning. Slight chances for
storms will be possible over over the favored ridge tops for the
rest of the CWA, but look to only lead to a few isolated cells.
Additional chances are expected for Friday but continue the focus
over Mohave Co, with even less chances for the rest of the CWA.
Chances over the weekend look to fall off, but don`t completely
erode. Non-zero chances for storms return for Saturday with
slightly better chances expected for Sunday. Slight chances will
be possible each afternoon into the next work week, but the
current forecast doesn`t show much in the way of widespread
convection then.
