.KEY MESSAGES...

* Slow warming trend continues into early next week. Hottest
  temperatures will be on Monday and Tuesday. Temperatures cool to
  near normal by midweek.

* Increasing moisture will bring a slight chance for thunderstorm
  activity next week, mainly for Mohave County, with much of the
  rest of the area remaining dry.

.DISCUSSION...through the end of next week.

Typical summer heat will prevail through early next week as high
pressure builds across the area. With heights slowly rising,
temperatures will gradually climb each day, rising 3-7 degrees
above normal by Monday and Tuesday. Despite being warmer than
the daily averages, it`s still pretty typical heat for late June
and heat risk largely remains in the moderate category. A few
pockets of major heat risk develop in parts of Mohave County and
the Colorado River Monday and Tuesday, but remain too brief and
spotty in nature to justify any heat products. As moisture pushes
into Arizona midweek and heights begin to fall as a low pressure
system offshore approaches, temperatures will moderate Tuesday
onward and return to near normal values.

Meanwhile, as the Four Corners high orients itself in a more
favored location for moisture advection, along with a weak low
over southern California strengthening the southerly flow, expect
increasing thunderstorm activity across Northwest Arizona Tuesday
onward. A fairly sharp contrast to drier conditions are expected
further west thanks to a slight southwesterly component of the
flow advecting drier air into the region, but storm chances look
to spread into the eastern Mojave Desert and perhaps Lincoln
County Wednesday and Thursday. Main concerns will be the potential
for some dry lightning initially, followed by more typical summer
like downpours and gusty winds midweek onward.

.AVIATION...For Harry Reid...For the 06Z Forecast Package...Winds
will follow a typical daily pattern, southwesterly winds overnight,
variable winds tomorrow morning, then south southeasterly winds in
the afternoon. Occasional weak gusts cannot be ruled out in the
afternoon and early evening. Otherwise, speeds should remain less
than 10 knots throughout the forecast period. Temperatures will
exceed 100F between 19Z and 04Z.

For the rest of southern Nevada, northwest Arizona and southeast
California...For the 06Z Forecast Package...Winds will mostly follow
usual daily patterns across the region through tomorrow. Winds
remain under 10 knots through the night and tomorrow morning. Gusty
southerly to southwesterly winds develop in the Owens Valley,
Colorado River Valley, and western Mojave Desert in the afternoon
and evening. Skies will be mostly clear. Periods of haze/smoke from
distant wildfires will be seen at times, primarily along and
south/east of the I-15 corridor.

&&

.SPOTTER INFORMATION STATEMENT...Spotters are encouraged to report
any significant weather or impacts according to standard operating
procedures.
