.KEY MESSAGES...

* Light snow continues through the early morning in the Sierra
  with periods of rain for lower elevations.

* Below average temperatures continue through this week with drier
  weather later in the week.

* Another chance for valley rain and mountain snow may arrive by
  late this weekend.

&&

.DISCUSSION...

* The upper level low pressure that produced rain and higher
  elevation snow Monday and Tuesday will exit the region by the
  afternoon. Light, scattered snow showers will persist until
  around 7-9 AM PDT in Mono County and the Tahoe basin. A more
  persistent band of light to moderate snowfall will continue in
  eastern Plumas and southern Lassen counties through the same
  time frame. Local camera networks are showing snow levels as low
  as lake level in Tahoe, to round 6,000` in Mono County. Snow
  levels will be around 5,500-6,500` through around 11 AM, then
  increase to around 7,500` the remainder of the day. Where we do
  see snow this morning, additional accumulations of 1-3 inches is
  likely (60-70%), with a low chance (10%) for locally higher
  amounts of 4-5". Snow rates will be 0.5" per hour or less.

* Currently in western NV, light rain showers continue for
  Mineral, southern Lyon, and Douglas counties northward through
  the greater Reno metro area. A band of light to moderate rain
  continues in central Washoe into Pershing County north of I-80.
  Otherwise, the rest of western NV is dry. These showers will
  continue through the around 8-10 AM for far western NV, to
  around 10-12 PM in the inner-basins. Snow levels this morning
  may fall to as low as 5,500-6,000`, with light snow
  accumulations of at best 1-2".

* For the remainder of the work-week into Saturday, a ridge of
  high pressure moves into the region. This will allow for a
  warming and drying trend through at least Saturday, with
  moderate to high confidence. By the end of the weekend,
  ensembles show the ridge breaking down. After that, there is
  considerable uncertainty in if we get a trough, ridge, or just
  zonal flow. -McKellar

  These conditions are present at KLOL/KNFL from roughly 11-18z
