Area Forecast Discussion
National Weather Service Elko NV
202 PM PDT Sat May 27 2017

.SYNOPSIS...Dry conditions in addition to a warming trend is
expected across the state over the Memorial Day weekend. High
temperatures will be in the 80s to near 90 for the next few days
before a cool down and opportunity for showers and thunderstorms
arrives for the middle of next week. Continued snowmelt from the
higher elevations will maintain elevated flows for small rivers
and streams.

&&

.SHORT TERM...Tonight through Monday.

High pressure will dominate weather across the Great Basin
bringing warm temperatures and dry conditions to NV through the
next several days. A few afternoon cumulus may develop but should
dissipate overnight. Temperatures will rise a few degrees over the
weekend with highs in the 80s and lows in the mid to upper 40s by
Monday.

.LONG TERM...Monday night through Saturday.

Monday night through Wednesday morning. A broad upper level ridge
will remain entrenched across the Great Basin bringing fair
weather to Nevada. This ridge will slowly drift eastward and break
down with the ridge leaving by Wednesday morning. An elongated
long wave trough will follow the departing ridge which will cause
an increase in cloudiness Tuesday onward. This period will be the
warmest for next week with highs in the 70s to 80s and lows in the
40s to 50s.

Wednesday through Saturday. The long wave trough will herald the
arrival of unsettled weather as multiple progressive troughs
impact the west coast. The amount of moisture associated with any
of these troughs is not to impressive but it will still be
sufficient to produce showers through the rest of the week. There
will be enough instability that afternoon thunderstorms will be
possible. The most potent of the short waves will impact on
Wednesday bringing gusty winds of 30s mph across the central and
eastern portions of Nevada. There should be a slight cooling of
temperatures with highs in the 70s and lows in the 40s.

&&

.AVIATION...VFR conditions and light winds for the next 24 hours at
all terminals.

&&

.HYDROLOGY...Temperatures will gradually rise over the Memorial
Day weekend into Tuesday of next week. All creeks that flow out of
mountainous areas should see significant rises over the next
several days.

The lower Humboldt River from Comus downstream through Winnemucca
to the Humboldt/Pershing County border will experience minor to
moderate flooding through the weekend. A Flood Warning remains in
effect.

The Jarbidge River has dropped below action stage. However, the
river is expected to increase Sunday and Monday as temperatures
warm.

Lamoille Creek is below minor flood stage but could rise again to
flood stage through the weekend as snowmelt increases. A flood
warning remains in effect.

The Humboldt River at Battle Mountain is below flood stage and
continues to slowly recede. It is expected to remain in action
stage through at least the middle of next week.

The Bruneau River continues to gradually fall below action stage.
However, warmer temperatures and snowmelt are expected to push the
river back into action stage, possible minor flood stage, early
next week.

flood stage over the weekend.
