Area Forecast Discussion
National Weather Service Elko NV
233 AM PDT Sat Apr 29 2017

.SYNOPSIS...Mainly dry conditions are expected for the weekend and
most of next week as Pacific high pressure tries to gain a
foothold over the Great Basin. High temperatures will rise into
the 60s most every day next week.


.SHORT TERM...Today through Monday. IR satellite imagery shows a
copious amount of cloudiness associated with the mean trough over
the central CONUS this morning. Circulation around the low center
continues to push clouds into eastern Nevada but west of the
Pequop Mountains, skies are clear. There seemed to be a small
pocket of fog developing between Gabbs and Round Mountain as early
as midnight. Not much in the way of weather is expected through
Monday and temperatures will warm to near normal.

Today through Sunday morning. The models consistently show this
as a dry period, possibly strengthening the Pacific high which
will extend a ridge pulse eastward over the Great Basin. High
temperatures will generally be in the 50s. Low temperatures will
range from the mid 20s to the mid 30s.

Sunday afternoon through Monday. There will be a small chance for least on Sunday. Although the Pacific ridge remains
strong, the models are consistently showing the ridge buckling as
yet another shortwave brushes northern Nevada. Timing of this wave
has been consistent, mainly affecting Elko County however there is
a northwest flow aloft that could alter the timing as we move into
the weekend. For now, Monday will be kept dry, but we shall see.
High temperatures will generally be in the 60s. Low temperatures
will be in the 30s.

.LONG TERM...Monday night through next Friday

Northwest flow Monday night and Tuesday and dry with lows Monday
night in the mid to upper 30s. Tuesday afternoon highs will be in
the upper 50s to mid 60s.

Upper ridging moves in for Wednesday and Thursday and
temperatures are expected to warm to above normal levels. Look
for afternoon highs in the 70s by Thursday with some areas in the
western sections of the forecast area pushing near 80 degrees.
Low temperatures Wednesday and Thursday night should be mainly in
the 40s.

Long term models really go out of sync beginning on Friday and
through the weekend. They do agree, however, that upper level
troffing begins to move into our West with some moisture
streaming in from the Pacific. Another thing that they have been
consistent on the past couple of days is indicating some
afternoon convection occurring on Friday afternoon across Nevada.
Temperatures still warm on Friday in the 70`s.


.AVIATION...VFR conditions all terminals with an increase in high
clouds tonight. Northerly winds 15 kts gusting to 25 kts this
afternoon KTPH and KELY.


.HYDROLOGY...Daytime temperatures will warm into the 60s
beginning this weekend which could lead to an increase in snow-
melt and more runoff into streams.

Here are the locations where flood warnings are currently in

Humboldt River - Battle Mountain: Minor flooding continues.

Humboldt River - Comus, near Winnemucca: Minor to Moderate
flooding continues.

Warmer temperatures may cause increased snowmelt beginning this
weekend which could lead to increased flows. The following rivers
are running high but are below flood stage:

Wildhorse Dam - at Wildhorse

Owyhee River - at Wildhorse

Owyhee River - near Mountain City

Bruneau River - near Rowland
