.KEY MESSAGES...

* Mostly dry with light winds and a gradual warming trend through
  Sunday.

* Quick moving trough brings mountain rain and snow showers along
  with areawide breezy winds on Monday.

* Warming trend continues most of next week, with widespread 70s
  and 80s in the valleys, 50s and 60s in the mountains.

.DISCUSSION...

* Looking at current 3am radar imagery, light lake-effect snow
  showers are forming off Pyramid Lake and moving south. These
  will continue trough around 7-8am. A trace to at most 1" of
  accumulations are possible, which could lead to slick roads
  along I-80 (mostly west of US-95), as well as US-50. A few light
  showers can`t be ruled out in the greater Reno metro area and
  even as far west as Lake Tahoe.

* Ridge moves into the region today, allowing for a slight uptick
  in temperatures. However, readings remain up to 10 degrees
  below average for early April with light east/northeast winds.
  All precipitation has moved out of the region, with left over
  low clouds banking against the eastern Sierra. With the
  aforementioned ridge shifting overhead, temperatures will
  continue to increase into the weekend. We finally return to
  April-like temperatures for Saturday, then above average
  temperatures by Sunday.

* A trough will quickly pass through the northern CA into the
  northern Rockies overnight Sunday into Monday. Per latest
  blended guidance, this feature will give us 20-30% for light
  precipitation in the Tahoe area. The best chances (40-60%) for
  precipitation remain in western Lassen County, Surprise Valley,
  and far northern Washoe County. These areas have around at
  40-50% chance for at least 0.10" of liquid. Snow levels remain
  above 7,000`, so snow impacts are very limited. As for western
  NV, the most we`ll see from this will be an increase in
  southwest winds, with gusts between 30-40 mph. Finally, high
  temperatures tumble around 4-8 degrees.

* From Tuesday through at Friday, high pressure builds across much
  of the western US. Temperatures will soar well above average,
  with widespread 70s to a few 80 degree readings in western NV
  and upper 50s to mid-60s in the eastern Sierra. By the end of
  the next week, ensembles all show the ridge continuing to shift
  east with long-wave trough pattern returning to the area. But,
  details and confidence is low. -McKellar

.AVIATION...

* VFR conditions through the weekend with light east/northeast
  winds today and Saturday. Winds remains light from the
  west/southwest by Sunday.

* Freezing fog is likely for TRK this morning under clear skies
  and residual moisture from the recent storm. Confidence is 80%
  for LIFR between 10z-18z. The chance of fog formation in other
  Sierra valleys, including around Mono Lake and KTVL, have lower
  20% chances. -McKellar
