Area Forecast Discussion
National Weather Service Reno NV
308 PM PST Thu Feb 9 2017

.SYNOPSIS...

A major storm is impacting the region with periods of heavy
rainfall, flooding, strong to damaging winds, and high elevation
snow. As the final round of precipitation moves through this
evening the flooding potential increases for creeks, streams, and
poor drainage areas. Drier and cooler weather will be the story
for this weekend.

&&

.SHORT TERM...

STRONG WINDS THROUGH THIS EVENING:

Very strong wind gusts over 80 mph have been reported so far today
and damaging winds are still impacting the region, especially
from the Sierra Front Range eastward, including downed trees and
power lines and road closures including parts of highway 395 in
Mono County. Blowing dust has created visibilities near zero at
times in the Mason and Smith Valleys and for Highway 95 and
alternate 50, including portions of Mineral and Churchill
Counties. Sierra ridges are gusting over 90 mph. These damaging
winds will continue through this evening before decreasing
overnight. All High Wind Warnings remain in effect. Stay away from
and do not drive over downed power lines.

RAIN AND SNOW THROUGH TONIGHT:

Heavy rain and high elevation snow arrived on schedule bringing
rapid rises on rivers and creeks with multiple flood warnings
currently in effect. Current radar shows a band of heavy
precipitation across the Sierra associated with the latest
atmospheric river. This band of heaviest precipitation will
continue through the evening hours and slowly shift south through
early Friday morning. Snow levels have dropped to between 7000
and 8000 feet currently, and should drop to around 6000 feet
Friday morning. Despite falling snow levels, heavy rain and flood
impacts will continue or increase through this evening and some
rivers will stay above flood stage into the weekend with some
impacts continuing into next week. See the hydrology discussion
below for details. JCM

FRIDAY AND SATURDAY WEATHER:

The bulk of the heaviest precipitation will move southward during
the day tomorrow as colder air works its way in behind the storm.
Snow levels are expected to drop to western Nevada valley floors
by tomorrow evening, but deepest moisture will be across Mono County
by that time. However, we could see some light accumulations of
snow across western Nevada as far south as Highway 50 tomorrow,
possibly impacting the evening commute. There will be some residual
snow showers Saturday morning, especially south of Highway 50,
but overall dry conditions will ensue as high pressure builds in
Saturday. -Edan/Jon

.LONG TERM...Saturday night through Thursday...

An upper ridge builds across the area Sunday through Wednesday with
a very weak shortwave possibly moving over the top of the ridge and
flattening it a bit Mon-Tue. This wave could bring some increase in
high clouds, but lower levels of the atmosphere will remain too dry
and stable for any precipitation. Underneath the ridge, temperatures
will warm fastest at the upper elevations which will establish
inversions, strongest Sun-Mon when mixing will be held to 2000 ft
AGL or less. Clouds may impact warming Tuesday and slow warming a
bit but the general trend should be for a gradual warming of valleys
through Wednesday and slightly improve mixing (winds will remain
light and thus ventilation will not see as much of an improvement).

Looking to late in the long term period, the pattern once again
turns stormy with moisture transport projections from the GFS
ensemble showing a moderate to high probability (50-80%) for a weak
atmospheric river for central and northern California by Wednesday
night or Thursday. Some possible good news as far as limiting the
flood threat late next week is that the latest operational model
simulations show a quick trend for lowering snow levels after the
initial precipitation push. This seems to be backed up by the GFS
ensemble trend which pushes the probabilities for atmospheric river
conditions more into central and southern California by around next
weekend. This hints at a colder, more mid-latitude source for
moisture beyond late next week. Still, as usual since early January,
lower valley small creeks and streams could still see rises given
very moist soils if snow levels remain above valley floors.

.AVIATION...

Widespread valley gusts of 40 to 55 kts are likely into evening in
areas of western NV and eastern CA that are not experiencing steady
rain, with gusts generally decreasing to under 35 kts in areas with
steady rain. LLWS with gains/losses between 10-30 kts have been
reported blo 010 AGL near the KRNO terminal this afternoon. In
addition to strong and gusty valley/terminal winds, turbulence
(sometimes mod-svr thru this evening based on recent PIREPS) and
mountain waves can be expected tonight in the lee of the Sierra,
with mountain waves decreasing in intensity where moisture has
increased significantly. Gusts across Sierra ridges are exceeding 90
kts...and could gust as high as 115 kts through evening.

In addition to the wind, widespread significant reductions in
VIS/CIGS with rain and higher elevation snow in the Sierra and
across northeast CA will spread into western Nevada this afternoon
and evening. This includes KCXP and KRNO, where there is a 50-60
percent chance for brief periods of MVFR conditions after 01Z/5PM
due to lowering ceilings with the main rain band. Farther east into
west-central NV, areas of blowing dust are reducing VIS to below
5SM, locally below 3SM, with radar returns possibly indicating a
large areas of lofted dust (above 15 kft MSL) east of Walker Lake.
Dust should settle once rain develops out in the Basin and Range
tonight...although higher terrain obscuration will be likely with
rain.

Rain will turn to snow for Sierra terminals Friday morning with
several inches of snow likely to accumulate. While some snow may
make it down into the lower valley floors including KRNO-KCXP early
Saturday morning with a final wave of showers, mild ground
temperatures and light intensity snow will likely preclude
accumulation on runways/taxiways. Snyder/Hohmann

.HYDROLOGY...

* Severe flooding is ongoing in Plumas County and along the Pit and
  Susan Rivers in Lassen County. Flood impacts to continue into this
  weekend.
* Flooding possible for creeks, streams, urban areas and drainage
  basins in the Tahoe Basin, eastern Sierra and western
  Nevada into Friday.

Band of heavy precipitation associated with an atmospheric river
will continue to push across the Sierra and western Nevada through
early Friday morning. Snow levels have dropped to between 7000 and
8000 feet, but this is not quite low enough to reduce the
severity of flood impacts in portions of Plumas and Lassen Counties.

Around the Tahoe Basin and western Nevada, main threat for flooding
remains along creeks, streams, and drainage basins/farmland where
water collects from creeks running out of the Carson Range. Snow
levels below 8000 feet usually prevent flooding along the Carson,
Truckee and Walker Rivers. However on going high flows and 1-3
inches of rain may cause the East and West Forks of the Carson River
and the Truckee River at Vista to nudge into minor flood stage this
evening and tonight.

Rainfall should diminish north of I-80 after 5pm, the decrease
around Reno-Tahoe after midnight, and finally by Friday morning
along the crest of Mono County.

However once the rain ends, the flood impacts will continue well
into the weekend. The Middle Fork of the Feather and Pit Rivers are
forecast to remain above flood stage until Sunday or Monday, which
will greatly hamper recovery efforts. Flood waters will be very slow
to drain for communities around the Tahoe Basin, where snow berms
are trapping water in street and homes.

Current rainfall rates are decreasing across the region as one
atmospheric river moves off to our south. Flood issues on creeks,
and basins will lessen this evening. However low lying areas may
remain inundated, especially the Sierra Valley, Washoe Valley and
Carson Valley. High flows on the Truckee and Carson River will be
slow to move down stream, so those along the Truckee below Derby Dam
and the Carson below Genoa should notice a significant
increase in flows tonight and early tomorrow.

For the Feather River from the Sierra Valley to Portola and the Pit
River across northwest Lassen County, flood impacts are likely to
persist though Wednesday, then become more severe on Thursday and
into Friday. Brong
