.SYNOPSIS...Temperatures across the region will climb above normal
today with the warming trend continuing through midweek. Dry
conditions will prevail as well thanks to the ridge of high
pressure building over the Western US. Winds will pick up across
the western Mojave Desert and southern Great Basin today with
lighter winds returning on Tuesday and Wednesday.

&&

.SHORT TERM...through Tuesday.

Broad ridge axis will continue to build overhead today and
tomorrow, allowing for a continued warming trend and dry weather.
A few high clouds will pass through our northern zones associated
with a passing shortwave to our north, with a modest increase in
afternoon southwesterly winds as well. However, wind gusts will
remain below any headline levels and will be more of a nuisance
than anything else. Strongest winds this afternoon will be across
the southern Great Basin and western Mojave Desert, where a few
gusts of 30-35 mph will be possible. Meanwhile, afternoon highs
will climb several degrees warmer today, rising 6 to 10 degrees
above normal, with further warming expected Tuesday.

.LONG TERM...Wednesday through Sunday.

Temperatures continue to climb through the end of the workweek as
heights aloft build. Highs should be 10 to 15 degrees above normal
by Thursday and 15 to 20 degrees above normal by Friday. This
pattern should yield widespread Minor (Level 1) HeatRisk with
pockets of Moderate (Level 2) 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. Plan ahead for heat, especially if spending time
outdoors.

Forecast confidence decreases going into next weekend. An upper
level trough will move from the Pacific Ocean into the western
United States. The ECMWF depicts a shallower and faster moving
trough compared to the GEFS, which shows a deeper and slower moving
trough. Low confidence is reflected in the NBM, where the spread in
potential high temperatures and maximum wind gusts increases
Saturday onward.

and diurnal winds will continue through the morning before gusty
southwesterly winds of up to 20 knots develop between 20Z and 22Z.

Reid above.  Elsewhere across the region, north to northwest winds
will prevail at KBIH with speeds generally remaining less than 15
knots.  Across the western Mojave Desert, Typical westerly winds can
be expected, with occasional gusts to 30 knots possible after 22Z.

occasional gusts of up to 20 knots are expected during the
afternoon, followed by winds of less than 12 knots thereafter. VFR
conditions will prevail throughout the TAF period with FEW to SCT
