.DISCUSSION...through early next week.

Another hot summer afternoon is underway, with regional
temperatures running near or slightly above where they were this
time yesterday. Similar conditions are expected again tomorrow,
with only very slight cooling of a degree or two in response to
weak troughing approaching northern California. Given the very
modest cooling expected, and the fact that temperatures will still
remain well above normal, extended the heat advisories and extreme
heat warnings one more day to account for moderate to major heat
risk that still persists through tomorrow evening.

Aside from the heat, a few very weak showers and perhaps a few
lightning strikes will be possible across the Sierra and
Esmeralda county today and tomorrow during the afternoon and
evening hours. Not expecting much in the way of significant impact
with this activity, though gusty winds and dry lightning strikes
would be the main concerns, though overall the risk will remain
fairly low. By Thursday, deepening southerly flow ahead of a weak
trough across California will spread low-grade monsoonal moisture
into our eastern zones, mainly across far southern Nevada, the
eastern Mojave Desert, and Northwest Arizona. Guidance remains
uncertain exactly how far west the moisture will spread, but best
chances remain focused across Mohave County. Initial storm
activity may feature some dry lightning, but storms will tend to
moisten quickly by Friday as deeper moisture spreads northward.
Main threats Thursday through Saturday with storms across our
eastern zones will be locally gusty winds and brief downpours.
Drier air will spread back in by Sunday, but a more favorable
monsoon pattern may develop by the middle of next week.

.AVIATION...For Harry Reid...For the 06Z Forecast Package...Light
winds tonight and Wednesday morning give way to breezy south-
southwest winds tomorrow. Gusts 15-25 knots. Some uncertainty in the
onset time, with some guidance as early as 18z, but the most likely
scenario is 20-21z. Winds subside after sunset. Few mid-level and
high clouds. Temperatures to exceed 100F between 18z and 05z, with a
peak around 110F.

For the rest of southern Nevada, northwest Arizona and southeast
California...For the 06Z Forecast Package...Light winds give way to
breezy southerly/westerly winds Wednesday afternoon and evening.
Gusts 15-25 knots. Mostly clear skies with just a few mid-level and
high clouds across much of the area. The exception to this is
western Inyo County and the southern Great Basin as scattered
afternoon convection develops on the high terrain. Main concern with
this activity will be gusty outflow winds, especially in the Owens
Valley and Esmeralda County. Precipitation chances wane around
sunset, with dry conditions prevailing overnight.
