.DISCUSSION...

* A really nice warm, dry spring day is in store for today. We`ll
  see high temperatures in the upper 60s to low 70s for much of
  western NV and eastern Lassen County. Highs for our eastern
  Sierra communities will be in the mid to upper 50s. Winds will
  generally light from west with increasing high level clouds by
  the afternoon.

* A quick system arrives on Monday. There are no significant
  changes to the forecast. There remains a 25-35% chance for
  precipitation in the Tahoe Basin, a 35-45% chance for western
  Lassen County, to a 40-60% chance in the Surprise Valley and far
  northern Washoe County. Overall liquid amounts have not changed,
  and we`re still looking at between a trace to at best 0.20" in
  the Sierra with minimal snow accumulations above 7,000`. Winds
  will become breezy along the Sierra ridges, with gusts between
  60-80 mph. We`re also looking at breezy conditions in western
  NV, with gusts upwards of 30 mph. This will have impacts to
  boating/lake conditions, especially for Pyramid Lake. This
  system moves out the region by Monday evening.

* High pressure returns Tuesday through at least Thursday. This
  will allow for warm, late spring-like temperatures that are 15
  to 20 degrees above average for mid-April. Thursday is looking
  like the warmest day this upcoming week, with upper 70s to mid
  80s in western NV and eastern Lassen County, to even mid 60s to
  low 70s for the Sierra communities.

* Ensembles show the aforementioned ridge shifting east with a
  trough approaching the west coast by Friday through the weekend.
  But there is still considerable uncertainties with the evolution
  of this upper level pattern. At this time, temperatures will
  trend to back to average with an increase in winds. -McKellar

.AVIATION...

* VFR conditions with only high cirrus clouds to contend with
  today. Winds will be light from the west this afternoon.

* Monday, southwest winds will amplify along the ridges to around
  65 kts. This will introduce LLWS and turbulence for the Sierra
  and far western NV terminals. Showers with this system will be
  mostly rain with some mixing of snow for the higher elevations
  above 6,000-7,000 ft. They will also be limited to NE California
  and far northwestern Nevada, and will be light. -McKellar
