Area Forecast Discussion
National Weather Service Las Vegas NV
436 PM PDT Thu Jun 12 2025

.SYNOPSIS...Hot, dry, and breezy conditions persist through the
forecast period. Temperatures remain above normal with only subtle
day-to-day variations. An uptick in winds is likely early next week
as a weak system moves through, bringing increased fire danger to
the area.

.DISCUSSION...through Wednesday.

We remain in this southwesterly flow regime for the next several
days as a trough sits off the PacNW coast and a broad ridge lingers
over the central US. This will keep breezy winds and above-normal
temperatures around. Chances for wind impacts are less than 30%
across the area, but they are going to increase fire danger. Where
fuels are ready, new fire starts may spread rapidly. Where fuels are
not ready, notable drying and curing is anticipated. With no
precipitation potential in sight, fire danger is only expected to
increase over the next week or two.

Over the weekend, the central US ridge becomes more amplified,
leading to rising heights and temperatures in our area. The peak of
the heat looks to be on Sunday when highs are forecast to be 6-10
degrees above normal. This may push the lowest valleys into major
HeatRisk, so we`ll have to monitor trends as we assess the need for
any heat headlines.

Some subtle relief is set to arrive early next week as a shortwave
moves through. Forecast highs drop 3-5 degrees during this time.
However, this will likely be accompanied by an increase in winds and
fire danger. Strongest winds expected across the western Mojave
Desert where there is a ~50% chance of wind impacts. This system is
a progressive one, meaning heights and temperatures will quickly
resume their increasing trend mid-week.
