.KEY MESSAGES...

  potential today and tonight.

.DISCUSSION...

Wildfire danger will be heightened today due to the combination
of hot, dry and breezy weather, and July 4th activities. See the
Fire Weather discussion below for more details.

Ongoing wildfires across Southern California, most notably the
Madre fire burning north of Santa Maria, will continue to generate
smoke and haze. As southwesterly winds overspread the region
today into the weekend, expect at least patchy smoke and
widespread haze to affect much of adjacent Southern California and
Southern Nevada. This combined with July 4th festivities may
result in poor air quality today through the weekend. Follow the
guidance of local air quality agencies if you have outdoor plans
over the holiday weekend.

As we get into next week, ensembles depict a cutoff low off of
the Southern California coast will gradually retrograde, allowing
a powerful upper ridge of high pressure to build in across the
Four Corners region. This feature will slowly build westward,
becoming positioned over Southern California, Nevada and western
Arizona. Long-range ensembles are rather confident on this
dominant ridge having a prolonged presence across the Desert
Southwest. As such, the potential for a significant multi-day heat
event are on the rise. Heat Risk will climb daily, with
widespread Major to Extreme Heat Risk evident Wednesday and
Thursday of next week, likely continuing through the following
weekend. We will have to monitor trends closely as this feature
looks to bring the hottest weather we have seen since last summer.

.FIRE WEATHER...The combination of hot and dry weather with
increasing southwesterly breezes will lead to high fire spread
potential today into early tonight. This combined with dry
vegetation and July 4th activities will lead to an increased risk of
wildfires. Red Flag Warnings remain in effect for much of Southern
Nevada into western Arizona beginning late this morning and lasting
into tonight. Hot and dry conditions will persist into the weekend
and beyond, but winds will generally be on a downward trend.
