Area Forecast Discussion
National Weather Service Elko NV
229 PM PDT Mon Oct 16 2017
.SYNOPSIS...Mostly sunny and warm through Thursday. Increasing
clouds across northwestern NV on Thursday, which will lower and
expand southeastward across the region Thursday night into Friday
as a frontal passage brings showers to the region. Precipitation
ends from west to east Friday night into Saturday with cooler
temperatures next weekend.
&&
.SHORT TERM...This evening through Thursday. Weak ridging across
the inter-mountain west tonight begins to break down on Tuesday as
shortwave energy pushes west to east through the pacific
northwest. Should still see a couple more degrees of warming on
Tuesday. Slightly lower 500mb heights Tuesday night into Wednesday
under a near zonal flow aloft will result in a couple degrees of
cooling. The ridging and weak zonal flow may result in some smoke
from northern and central CA wildfires drifting east into NV on
Tuesday.
Broad trough energy digs southeast into the offshore waters of
the west coast late Wednesday into Thursday, which will result in
zonal flow over northern NV backing to a southwesterly direction.
Dry conditions continue on Thursday, however winds will become
southwesterly and increase into Thursday afternoon ahead of the
approaching trough.
.LONG TERM...Thursday night through next Monday. 100kt jet energy
pushes into northwestern NV Thursday night associated with trough
energy that will bring some valley rain and mountain snow to
mainly just northern NV into Friday morning. Post-frontal
conditions will be drier and colder late Friday morning with some
lingering valley showers likely transitioning to snow flurries by
Friday afternoon as precipitation exits to the east southeast. With
the possible exception of mountains near the Oregon and Idaho
borders, the area should be dry this weekend, with mid 50s to low
60s on Saturday warming into the 60s across the region on Sunday.
&&
.AVIATION...VFR conditions at all terminals through Tuesday as
weak high pressure slowly builds into the region. The only concern
at this time will be the potential for smoke moving in from the
west on Tuesday due to wildfires in northern California.
&&
.LKN WATCHES/WARNINGS/ADVISORIES...None.
