.DISCUSSION...

After a few cloudy days limited the amount of warming, a building
ridge of high pressure over CA-NV will lead to fewer clouds and a
warming trend starting today, with mainly light winds. Highs will
climb into the mid-upper 60s for lower elevations and well into
the 50s for Sierra communities. Even more warming will arrive
Monday-Tuesday, with highs reaching 80 for the first time in 2025
in some valleys by Tuesday. Record highs for that date (March 25)
of 81 degrees at Reno and 67 for South Lake Tahoe are within
reach. While both days should remain dry, afternoon cumulus
buildups are likely to develop in Tuesday`s very warm air mass.

Higher elevations will see some acceleration of snowmelt during
this warmup, mainly in the daytime but even a bit of melting at
night, as low temperatures are projected to settle between 35 and
40 degrees.

From Wednesday onward, the high pressure ridge is projected to
give way to a series of Pacific storm systems. The initial storm
track will favor most of the moisture staying farther north into
the Pacific Northwest or being blocked by the Sierra crest, with
precip shadowing for most of the eastern Sierra and western NV.
The primary effects for Wednesday-Thursday will be increased
winds and a cooling trend. Wind-wise, peak gusts are projected to
increase to 30-45 mph across northwest/far western NV Wednesday
afternoon, then edge further upward on Thursday across most of the
region. Blended guidance shows a 50-70% chance for peak gusts of
50+ mph in several western NV communities Thursday afternoon.
Sierra ridge gusts of 80+ mph are also in the mix by Thursday.

Temperature-wise, west central NV sees their best chance of 80+
degrees on Wednesday, while highs start to trend downward
elsewhere. A more notable cooling then arrives by Thursday with
highs closer to late March averages around 50 degrees for Sierra
communities and around 60 for western NV valleys, although the
US-95 corridor may squeeze out one more 70 degree day.

By the end of the week into the start of next weekend, mainly dry
conditions and near-average temperatures are expected. Then from
Sunday onward into the first few days of April, longer range
guidance continues to favor a more active pattern returning to
the region, bringing increased chances for periods of heavier
mountain snow, valley rain and gusty winds. MJD

.AVIATION...

Aside from areas of FZFG producing IFR/LIFR conditions around
KTRK and some northern Sierra valleys mainly from 09-17Z each
morning through Tuesday, VFR conditions with light winds will
prevail across the region through Tuesday.

The next period with weather impacts to aviation will be
increasing winds Wednesday-Thursday leading to more turbulent
conditions, with possible LLWS at times around the main
terminals. MJD
