Area Forecast Discussion
National Weather Service Reno NV
236 AM PDT Sat Oct 20 2018


A mild pattern with above average afternoon temperatures will 
continue through next week for northeast California and western 
Nevada. A weak low pressure system moving across the region may 
bring light showers to far eastern Churchill and Pershing Counties
Sunday and Monday. Late next week, low pressure moving into the 
Pacific Northwest may bring some increase in winds and clouds.



Northeast California and western Nevada remain between a broad
upper low over southern California and an upper ridge centered
over Oregon and Idaho. Easterly flow aloft and thermal gradients
between the Great Basin and western Sierra slopes are inducing 
gusty easterly winds to between 40-60 mph along the Sierra crest. 
In addition, Lake Tahoe is experiencing winds between 10 and 20
mph, especially for the eastern side of the lake near/north of
Spooner Summit. Winds should slacken this afternoon as the gradient
between the ridge and trough weakens.

Except for the elevated winds over ridges and for Lake Tahoe this
morning, weather conditions today should remain similar to recent
days with a mild afternoon, generally light winds, and clear skies.

For Sunday and Monday, the ridge center will erode with the weak 
trough of low pressure over southern Nevada and California moving 
overhead. A wave moving around the eastern side of the trough will
bring increasing mid and high level moisture over central and eastern
NV. While that part of the state will have the the best chances for
precipitation, a few light showers could form each day in far eastern
Churchill and Pershing Counties. Elsewhere for northeast CA and western
NV Sunday and Monday, little change in the weather is expected from
the trough as forcing for precipitation is expected to be insufficient.

.LONG TERM...Tuesday through Friday... 

Ridge builds back into the California coast next week, pushing the
storm track well into the Pacific Northwest. Models continue to trend
farther north with the moisture coming into the West Coast, keeping
northern CA/NV dry through next week. We have continued to lower POPs
in the long term and removed all mentions of precip in our area as
moisture will remain north in OR/WA. Temperatures will remain above
normal for this time of year, with highs in the 70s across western
Nevada and 60s in the Sierra valleys. -Hoon



VFR conditions through the weekend with breezy ridge winds over the 
Sierra crest through this morning. Some weak mountain wave turbulence
is possible this morning, although winds aloft will weaken by this
afternoon. -Hoon
