Area Forecast Discussion
National Weather Service Elko NV
225 PM PDT Thu Apr 26 2018

.SYNOPSIS...Much above normal temperatures will continue today and
Friday. A storm system moving into the region over the weekend
will bring cooler temperatures along with a chance of showers and
thunderstorms, mainly over northern Nevada.


.SHORT TERM...Today through Saturday. Another warm and dry day is
in store today thanks to a strong ridge of high pressure over the
region. An upper low approaching the northern CA and southern
Oregon coast on Friday will bring some cooling to northwest NV
while the rest of the forecast area will remain about the same.
This approaching low pressure system will also bring enough
moisture and instability Friday afternoon for some isolated
thunderstorms across northern NV, with the best chances across
northwest Elko county southward into Lander and Eureka counties.
With these thunderstorms there is a possibility that they can form
over a salt flat and cause a dust storm with gusty outflows but
this will be hard to see until the onset of convection. This low
pressure system will also bring breezy conditions, especially
across central NV where south winds of 15 to 30 mph are expected.
On Saturday the center of the upper low will move into northern CA
and southwest Oregon. Continued instability and diurnal heating
will promote thunderstorm activity. This will be mainly in Elko,
Humboldt, and northern Lander and Eureka counties as moisture in
the low moves northward. by Sunday the low will be translating
across southern Idaho and northern NV spreading moisture further
southward. This increase in moisture will allow for showers to
cover a larger area. Instability will remain sufficient that
thunderstorms can form during the afternoon hours even as cooler
air moves into the region. as the low brings cooler air into the
region expect 10-15 degrees of cooling by Saturday and additional
5 to 10 degrees by Sunday.

.LONG TERM...Sunday night through next Thursday. A closed low over
northern portions of the inter-mountain west Sunday afternoon will
open into a broad trough by Sunday night, and sag further south
through central and into southern portions of NV. Scattered rain
and snow showers will linger across the region Sunday night
through Monday night. Snow levels are expected to lower into the
6000-6500 foot range both Sunday night and again on Monday night,
however little if any accumulation is expected even on grassy
surfaces for most areas. Best chance for a little accumulation
would be along and near the highway 50 corridor in central NV
where elevations are higher. These areas could see a quarter inch
to possibly an inch of snow to grassy areas all totaled by Tuesday
morning. No impacts are expected. Showers end from west to east
Tuesday into Tuesday night. Warmer Wednesday on with high
temperatures climbing back above normal.


.AVIATION...Increasing southerly winds across most of central NV
by late Friday morning with highest gusts in the 20-30kt range for
both KTPH and KELY. Gusty westerly winds Friday afternoon across
northwestern NV, including KWMC and possibly KBAM with gusts
generally in the 15-25kt range.

Instability sets up across portions of north-central NV early to
late afternoon on Friday, which may result in TS at KBAM. Late
afternoon to early evening storms may reach KEKO.
