.KEY MESSAGES...

* Light snow showers possible this afternoon, mainly in the
  mountains.

* Cold temperatures with hard freezes widespread through Friday
  morning.

* Warming trend starting this weekend, with well above normal
  temperatures much of next week. A few showers possible Monday,
  primarily north of I-80.

.DISCUSSION...

* A cold upper level trough will continue to slowly move east
  today. With cold air in place and remnant moisture, we`ll
  maintain a slight 15-20% chance for snow showers in the Sierra.
  Any accumulations will be light, generally 1" or less. Today`s
  temperatures will feel more like mid-February instead of early
  April. High temperatures will be in the low 50s in western NV
  and mid 30s to low 40s for the eastern Sierra communities.

* By Friday into Sunday, a positively tilted ridge will move into
  the region. High temperatures for Friday will increase around
  3-6 degrees across the area, with an additional warming in store
  for Saturday and Sunday. By Saturday, temperatures will rebound
  to around normal readings for April 5th, which is low to mid 60s
  in western NV and the low to mid 50s for the eastern Sierra
  communities. Further warming is expected for Sunday, with above
  average temperatures to end the weekend.

* By late Sunday into Monday, models and their respective ensemble
  solutions show a weak trough swinging through northern CA into
  the northern Rockies. This will lead to a 20-40% for showers
  from the Tahoe Basin northward into Lassen County. Accumulations
  will be light, with a 20-40% chance for at least 0.10" of
  liquid. There is also a 35-50% chance for light showers in the
  Surprise Valley and far northern Washoe County, with a 20-40%
  chance for at least 0.10" of liquid.

* Heading into next week, there is still good confidence in a more
  pronounced warmup with a long-wave ridge over much of the
  western US. By Wednesday, the NBM still has 50-80% chance for
  highs of at least 80 degrees for western Nevada cities, with
  decent odds of 70s on Sunday and also on Tuesday. -McKellar

.AVIATION...

* A few isolated rain/snow showers with MVFR/IFR conditions are
  possible this afternoon across the eastern Sierra, generally 10%
  coverage or less.

* Otherwise VFR-MVFR clouds across W Nevada including RNO with
  light winds.

* With recent moisture and clearing skies, fog could be an issue
  Friday morning after 9z. Especially for KTRK (20%) -McKellar
