.SYNOPSIS...Warming weather will continue through the remainder of
the week, providing an early taste of summer as temperatures
climb to around 10 to 15 degrees above normal each day. Relief
will arrive in time for the weekend as a passing system impacts
the region, with increasing winds Friday and Saturday, as well as
gradually cooling temperatures this weekend into early next week.
No precipitation is forecast the next seven days.

&&

.SHORT TERM...through Thursday.

Low amplitude ridge which has built in across the Southwest will
build northward today and tomorrow, allowing for a continuation of
the warming trend and more dry and sunny weather. With heights
gradually rising, temperatures this afternoon will climb a few
degrees higher than temps reached Tuesday, and a few more degrees
by Thursday. This will put most areas in the ballpark of 12 to 18
degrees above normal, and the warmest weather yet of 2025. With
broad high pressure in place, winds will remain generally light,
although a deepening mixed layer will lead to breezy conditions
returning in the afternoons.

LONG TERM...Friday through Tuesday.

Friday will be the warmest day of the forecast period. Highs 15 to
20 degrees above average are expected and numerous daily high
temperature records are threatened at area climate sites - see the
Climate section below for more details. Although heights aloft begin
to decrease with the incoming trough, southwesterly warm air
advection and downslope winds off area mountains should offset any
cooling effects and allow temperatures to rise. Hot daytime
temperatures and warmer than average overnight lows result in
widespread Minor (Level 1 of 4) HeatRisk with pockets of Moderate
(Level 2 of 4) HeatRisk along the Colorado River, Death Valley, and
other areas of lower elevation in the Mojave Desert. This level of
heat primarily affects those that are sensitive to heat, have not
had time to acclimate to increased temperatures, or do not have
access to sufficient cooling or hydration. Remember to stay hydrated
and know where to find the nearest air conditioned space, especially
if spending time outdoors.

The previously mentioned incoming trough will bring notable changes
to winds and temperatures. Southwesterly surface winds begin to pick
up on Friday, but strengthen on Saturday as the trough axis moves
through and 850 mb winds intensify. The strongest winds develop
along a belt spanning San Bernardino, Clark, and Mohave counties.
Winds should weaken on Sunday as the trough continues east and the
pressure gradient relaxes. As heights aloft decrease, surface
temperatures decrease 10 degrees or more between Friday and Sunday,
closer to seasonal averages. Relatively cooler temperatures remain
going into early next week. No precipitation is expected with this
system.

California...For the 06Z Forecast Package...Quiet weather is
expected through Wednesday, with wind gusts less than 20 knots
except over the higher mountain ridges.
