Area Forecast Discussion
National Weather Service Reno NV
217 PM PDT Fri May 7 2021


Dry and breezy northwest breezes will become northeast to
easterly overnight, becoming gusty over the Sierra Crest and Tahoe
Basin. Cooler temperatures are expected through the weekend. Next
week will feature a warming trend with light winds.



Breezy and cooler conditions today behind the cold front that moved
through yesterday. We did issue a lake wind advisory for Pyramid
Lake today, mainly due to the northwest flow that is favorable for
choppy conditions on Pyramid, but overall the winds will be marginal
with gusts up to 30 mph. Elsewhere, some minor cross wind concerns
and minor wind shear may be possible with gusts up to 30-35 mph.

There is a very slight chance that we could pop a shower over
Mono-Mineral this afternoon, but as the trough axis moves out of
the region, the threat will push further into central and eastern
Nevada this evening.

Winds will become more northeast to easterly overnight and into
Saturday morning. Winds will become stronger over the Tahoe Basin
and across the Sierra Crest in the early morning hours Saturday.
The strongest winds will be along and west of the Sierra Crest,
along with gusts over Lake Tahoe up to 30 mph. Choppy conditions
are likely Saturday morning on the California side of Tahoe, but
should remain below lake wind advisory.

Temperatures may drop down to near or below freezing in the colder
Sierra valleys Saturday morning. Temperatures in the western
Nevada valleys should remain above freezing, but outlying/rural
valleys could see temperatures near the freezing mark Saturday
morning. It should be a mild/pleasant weekend across the region,
with temperatures cooling off a few degrees more to the 60s on
Sat/Sun, a few areas in western Nevada will hit 70 degrees.
Overall northeast winds will be lighter this weekend, but still
helping to keep the temperatures cool. -Hoon


Low pressure will remain in place Monday with another day of north-
northeast winds and some potential for gusty winds along the Sierra

Ridge of high pressure will build into the west coast by Tuesday
with warming temperatures into mid week. While most of the guidance
suggests highs in the 80s for the lower valleys with 70s-low 80s in
the Sierra, the high end of the ensemble spread is pushing the low
90s. This starts to raise the thunderstorm potential Wednesday and
Thursday, which is also showing up in a few simulations.

Low pressure should break down the ridge Friday-Saturday with breezy
winds and cooler conditions. Ensemble spread is rather large on the
track and strength of the trough, but there is some potential for
rainfall. Brong



Low pressure over Nevada will maintain periods of breezy winds (20-
30 kts) and light turbulence the next few days. Some stronger
turbulence is possible around the Tahoe Basin as northeast to east
winds increase over the Sierra ridges late tonight and Saturday
morning. A front will push into northern Nevada early Sunday with
some lower cloud ceilings possible north and east of SVE-RNO-HTH.
Doesn`t appear to be enough forcing for showers, but some virga is
not out of the question. Brong
