.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
today and a Fire Weather Watch is in effect for portions of
Lincoln County 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. As such, the Extreme Heat Watch has been upgraded to an
Extreme Heat Warning. 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...15 to 25 mph southerly-to-southwesterly winds
with gusts to 30 mph will pick up across Nye and Esmeralda
counties this afternoon as we continue to find our selves
sandwiched between low pressure to our west and high pressure
building in from the east. These winds combined with afternoon
relative humidities less than 15% and dry fuels will result in
critical fire weather conditions for Nye and Esmeralda counties
this afternoon. As such, a Red Flag Warning is in effect for the
aforementioned areas from 11:00 am PDT to 8:00 pm PDT today. Dry
conditions will continue with winds shifting into Lincoln County
on Wednesday. Low humidity combined with 15 to 20 mph
southwesterly winds gusting up to 30 mph will result in elevated
fire weather danger across NV fire weather zone 460 on Wednesday.
As such, a Fire Weather Watch has been issued for this zone on
Wednesday. Recreation with sparks and outdoor burning is not
recommended as any fires that start will develop and spread
quickly.
