Area Forecast Discussion
National Weather Service Reno NV
135 PM PDT Wed Oct 28 2020


High pressure will prevail over eastern California and western
Nevada for the upcoming week. Above average high temperatures will
continue through the middle of next week, with seasonably cool
nights. Winds will remain generally light with no rain or snow



We have now reached the dry and quiet steady-state weather
pattern with high pressure over CA-NV remaining largely in place
for the next several days. The only minor exception is when a
weak split trough moves through the western US next Tuesday-early
Wednesday with an increase in high cloud cover, but no rain or
snow. Expect above average daytime highs mainly in the mid 60s-
lower 70s, and typically cool fall nights in the 20s and 30s
(with teens for some of the usual cooler sites) through next
Wednesday. Winds will generally be light except for a moderate
increase in west winds north of Susanville-Gerlach on Friday, due
to a weak shortwave passage across the northern Rockies.

Later next week and beyond, there appears to be increasing
support for notable cooling in the November 6-11 period. Also the
latest runs of both the operational GFS and ECMWF do something we
haven`t seen in a while--dropping a low south from the Gulf of
Alaska to northern CA, spreading some meaningful moisture for the
eastern Sierra and Western NV around the 6th-7th (although we
would have a period of windy conditions prior to onset of any rain
or snow). However, ensemble guidance is currently more variable
on the timing of this potential storm system, with only about 15%
of the scenarios similar to the operational runs, and about 20-25%
of the scenarios holding off precip chances until the 8th or
later. At this time, we still have to be wary of these wetter
scenarios this far in advance, after seeing on other occasions
this month when a promising storm setup evolved into a dry
outcome. MJD



High pressure will produce VFR conditions with lighter winds and
clear skies through the weekend. A weak disturbance will pass
through the Pacific Northwest on Friday and may result in some
afternoon gusts around 20-25 kts across northeast CA and far
northwestern NV. Fuentes
