Area Forecast Discussion
National Weather Service Reno NV
240 PM PDT Fri Mar 23 2018


A break in precipitation is expected for most of today. Gusty
winds develop this afternoon ahead of a couple fast-moving and
colder storms that will move through with some snow for northeast
California into northwest Nevada this weekend. A warmer and drier
pattern is expected next week with temperatures trending above
average later in the week.


Breezy winds will continue through the evening with choppy
conditions on area lakes and some concerns for high profile vehicles
along Highway 395 and Interstate 580 corridor in typically windy
spots. A period of snow showers will move into northeast CA late
this evening before dropping south into the Tahoe area by late
tonight. Simulations continue to show a lack of significant forcing
with this upper wave as it brushes by late tonight into tomorrow
morning. Some travel impacts from snow in the Sierra from Tahoe
north and in northeast CA are expected as the snow will fall during
the overnight and morning hours. Out into western Nevada, impacts
should remain isolated tonight and Saturday morning as the
precipitation band is expected to fall apart as it approaches the
Interstate 80 corridor.

The next wave will drop through the main upper trough late Saturday
evening and overnight into early Sunday morning, bringing another
round of light to moderate snow showers and travel impacts to the
Sierra and northeast CA. The better moisture and instability will
remain north of Interstate 80, so snowfall in western Nevada should
remain light and sporadic in coverage. With the main upper trough
overhead on Sunday, snow and snow pellet showers will be possible in
the afternoon for much of the area; however, impacts should be
minimal with strong road heating making for mainly wet road
surfaces. -Edan

Few changes in the long term as high pressure over the East
Pacific sets up shop and moves the storm track north. The flow
will be from the north most of the week until the high begins to
break down some Friday. Surface winds would remain light and a
warming trend is in the offing. Highs 15 degrees below average
Monday will rise to a few degrees above average by Friday.

As far as precip, chances are quite low overall with a couple
exceptions. On Monday, there will be enough moisture on the
backside of the system for a few upslope snow showers in the
Eastern Sierra. Then on Wednesday, another short wave moves down
the east side of the ridge. Wednesday still looks dry with mainly
increased clouds as the forcing is directed into the Eastern Great
Basin. X


Breezy winds will continue through this evening with gusts 30-35
kt at the main terminals ahead of a cold front. This front will
bring another round of snow to eastern CA mainly from Tahoe
northward and in western NV north of I-80. IFR conditions with a
few inches of accumulating snow are likely for KTRK-KTVL
overnight. A dusting will be possible at KRNO-KCXP, but the
chances for that are very low.

Additional snow showers are possible Saturday night through
Sunday with the potential for very light accumulations again at
KTVL-KTRK, mainly from 06Z- 15Z. Little or no accumulation is
expected at all other terminals in western Nevada and for KMMH.
Isolated-scattered snow pellet showers look likely for Sunday
afternoon, with this activity winding down during the evening. MJD
