.KEY MESSAGES...

* High temperatures today and Friday reach the lower 80s across
  some western NV valleys but will fall short of record levels.

* The next weather system moves in late Friday into Saturday with
  a return of breezy winds and cooler temperatures for the weekend.

* Warm and dry conditions will return next week as high pressure
  sets up over the western US.

.DISCUSSION...

* Warm late spring-like conditions will continue into Friday.
  Temperatures will be around 15-20 degrees above average for mid-
  April. Although very warm, the chance of seeing any record highs
  remains low. Since we`re experiencing the first major warmup of
  the year, minor heat risks are possible for those sensitive to
  heat. We`ll see the return of the zephyr-like breezes this
  afternoon and again for Friday.

* Model ensembles still agree on a trough passing through the
  region late Friday into Saturday. This will first lead to gusty
  winds, especially along the ridges in the Sierra as well as into
  the inner basin and ranges. It will be breezy enough to be aware
  of choppy waters and possible adverse boating conditions for
  Lake Tahoe and Pyramid Lake on Saturday. This quick moving
  short-wave will be mostly dry for the majority of the area, with
  just a 15-25% chance for showers in northwest Lassen County and
  far northern Washoe County. Finally, temperatures will decrease
  in temperatures on Saturday and Sunday. But, readings will still
  be upwards of 5 degrees above average.

* Large scale ridge returns next week. This will allow for
  temperatures to once again increase well above average with
  overall light winds. There are a few ensembles that want to
  introduce a cutoff low over southern California by Monday into
  Tuesday, which may introduce light showers for the Sierra. There
  is low confidence in this feature. Otherwise, we are mostly dry
  the next 7 days. -McKellar

.AVIATION...

* Afternoon westerly breezes this afternoon with gusts up to 20 kt
  across all terminals. Wind gusts increase to around 25-30 kt
  Friday and Saturday due to a weak weather system passing through
  the area. This system may also introduce mountain wave turbulence
  and LLWS late Friday into early Saturday.

* Well above normal high temperatures today and Friday for W NV
  valleys, bringing abnormally high density altitudes for early
  April. -McKellar
