.DISCUSSION...through this weekend.

The combination of dry fuels, low humidity, and breezy southerly-
to-southwesterly winds will result in critical fire weather
conditions across portions of southern Nevada today and tomorrow.
A Red Flag Warning is in effect for Nye and Esmeralda counties which
will expire at 8pm this evening. The Fire Weather Watch that was in
effect for portions of Lincoln County Wednesday has been upgraded to
a Red Flag Warning that will run from 10 am to 8 pm tomorrow. For
more details, see the FIRE WEATHER section below.

Temperatures will continue to increase as a high pressure ridge
builds over the area. By tomorrow, southern Mohave County and the
Colorado River Valley will see widespread Major (Level 3 of 4)
HeatRisk where an Extreme Heat Warning remains in place. A shortwave
trough will swing through the Great Basin on Wednesday, which will
result in temperatures cooling a slightly from Wednesday to
Thursday. In response to the shortwave moving though to our north,
we will see the ridge axis shift over the western half of our
forecast area on Thursday. This will allow for temperatures across
our western zones to increase as we head into the weekend.
Meanwhile, our far southeastern zones will see temperatures "cool"
back down to near normal as we head into the weekend before heating
back up as we head into next week.

.FIRE WEATHER...A Red Flag Warning remains in place until 8pm this
evening for Esmeralda and central Nye counties where southwest winds
between 15-25 mph with gusts between 30-35 mph expected. Winds will
then diminish to below criteria through the overnight period. The
area of low pressure off the CA coast responsible for the gusty

of Lincoln County. The Fire Weather Watch for Lincoln County has
been upgraded to a Red Flag Warning which will run from 10am to 8pm
for Fire Weather Zone 461. Sustained winds 20-25 mph along with

outdoor burning is not recommended as any fires that start will
develop and spread quickly.
