.KEY MESSAGES...

* Cold temperatures with isolated showers are forecast today and
  Thursday. Hard freezes are expected for Western Nevada valleys
  and urban areas.

  above normal temperatures favored. Increases in stream flows are
  possible with snowmelt anticipated.

* Chances for light showers may return on Sunday and Monday though
  the region looks to stay mostly dry otherwise.

.DISCUSSION...

* A cold trough remains over the Western CONUS today and Thursday
  causing more limited forcing and allowing for rain/snow showers
  on both days. The latest NBM probabilities show around a 40-60%
  chance for measurable snow mostly for areas south of US-50 as
  well as Sierra mountain communities. The latest Winter Storm
  Severity Index (WSSI) shows not even much in the ways of minor
  impacts over the next two days as a result, so it will to be a
  better time to travel within the region compared to the snowy
  conditions we have seen over the last few days.

* Well below normal temperatures are projected through Friday
  morning. The main impact will be a high risk of hard freezes for
  Western NV valley and urban areas. The latest NBM Probabilities
  for sub-25 degrees range from around 30% at Reno Airport to
  around 60-80% at Yerington and Lovelock. Please consider
  protecting any early season vegetation and irrigation systems
  that you may have.

* A warming trend is in the forecast this weekend as winds turn
  more westerly/southwesterly. Parts of Western NV like Fallon
  look to see 50-70% probabilities for highs above 70 degrees
  starting on Sunday with similar numbers for highs above 80
  degrees starting next Wednesday. Portions of the Reno-Sparks
  area see a 20-30% chance of highs greater than 70 degrees begin
  on Sunday with similar probabilities of highs greater than 80
  degrees on Wednesday. With the warmer temperatures expected,
  some increased snowmelt could be result causing some minor rises
  in area rivers and streams. Long term forecast ensembles
  currently do not show a change in the upper air pattern until
  the weekend after this upcoming one, so these above normal
  temperatures could be here for a few days at least.

* Forecast ensembles still show a ridge building over the CA/NV
  region starting this weekend and going into next week. This
  should keep heavier precipitation systems to our north, but the
  latest NBM probabilities are currently showing a 30-40% chance
  of light showers on Sunday and Monday due to the influence of
  low pressure residing in the Gulf of Alaska. With the warmer
  daytime temperatures, the precipitation type looks to be mostly
  light rain though the Sierra portions of the region could see
  some light snow mixed in as snow levels and temperatures drop a
  bit overnight. QPF and snowfall totals look to be minimal at
  this time, so not anticipating many impacts on account of this
  precipitation. -078

.AVIATION...

Winds across the region look to be relatively light today compared
to the area winds seen over the last few day associated with the
departing winter storm system. Wintry shower chances are tapering
off early this morning allowing for conditions to improve by the mid-
morning. But after 02/20Z, convective models show isolated shower
chances increasing today which may cause brief sub-VFR conditions
at some area terminals should a shower pass nearby. While most of
the region looks to stay dry tomorrow, isolated Sierra shower
chances of 10-20% are in the forecast again during Thursday
afternoon. -078
