.SYNOPSIS...Dry weather will continue through through the week.
A ridge will build into the region and result in warmer
temperatures and lighter winds today. Other than some light west
to southwest breezes on Monday, winds will remain light through
the first part of next week. Temperatures will warm through the
week and remain above normal for the duration of the forecast.

&&

.SHORT TERM...Today through Monday.

Upper level ridging will build over the region today which will
bring dry conditions, light winds, and warmer temperatures. Compared
to yesterday, it will be noticeably warm as high temperatures will
run 5-10 higher than yesterday and there will be chilly north
breezes today.

On Monday, the ridge that tries to establishes itself over the
region will be knocked down by a system moving through the Pacific
Northwest. This shortwave will be well north of the area and will
not directly impact the local area other than some increased
cloudiness in the southern Great Basin. West to southwest winds will
increase Monday afternoon in response to an increasing pressure
gradient as the area of high pressure gets squished. The strongest
pressure gradient will remain over northern Nevada, thus not
expecting widespread wind impacts. Enhancement of west winds around
the Western Mojave Desert is possible which could bump wind and
impacts in that area, however wind impacts should remain minor in
most locations as high probability for wind gusts over 40 MPH
remains isolated. In addition, the westerly jet doesn`t push into
that area until late in the afternoon, so the potential for higher
gusts will be short lived before efficient mixing ends with the
setting sun. In general, expect winds gust to 20-30 MPH across the
region with some higher gusts to 35 MPH in the Sierra, Spring
Mountains, and the Western Mojave Desert...mainly late Monday
afternoon. The warm up continues on Monday as temperatures climb
another 5-10 degrees warmer than today`s temperatures. Above normal
temperatures are expected areawide Monday afternoon.

.LONG TERM...Tuesday through Saturday

Heights continue to rise on Tuesday as the upper level disturbance
moves east and the ridge rebounds. Temperatures venture further into
above normal territory, peaking Thursday into Friday with highs 10
to 15 degrees above average for mid-April. 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 planning on spending time outdoors. Forecast confidence decreases
towards next weekend. Guidance shows a low pressure system moving
into the west coast at the end of this week, bringing a decrease in
temperatures and increase in wind. However, there is disagreement
between ensembles in the trajectory of the low, which will have an
effect on the magnitude of these changes. Details should become more
apparent throughout the week - stay tuned.

California...For the 12Z Forecast Package... Light winds are
