.KEY MESSAGES...

* Cooler than average temperatures with overall dry conditions
  continue through Tuesday.

* There is a slight chance of afternoon showers and thunderstorms
  in the eastern Sierra from the Tahoe Basin southward through
  tomorrow.

* Temperatures return to seasonal averages by mid-week, then rise to
  above average by the end of the week.

.DISCUSSION...

* For today into Tuesday, an upper level trough will slowly move
  eastward through the Great Basin. With the low in place
  (allowing for larger scale lift) and increasing instability
  (cooling from aloft, orographic lift) there is a 10-30% chance
  for afternoon showers and thunderstorms, primarily from ~2 PM to
  7 PM. Main impacts will be erratic gusts up to 45 mph and brief
  heavy rainfall. Temperatures today and Tuesday remain below
  average for the date. We`ll see mostly 80s in western NV,
  eastern Lassen, and lower Mono counties; while eastern Sierra
  communities are in the 70s with 60s on the peaks.

* The aforementioned low kicks out early Wednesday with near-zonal
  flow aloft. A quick moving trough then brushes northern NV/OR
  border on Thursday. This feature will not have much impact on
  temperatures, which will increase back to seasonal readings for
  late June. However, we`ll see a brief uptick in winds Thursday
  afternoon. This will lead to a few hours of elevated fire
  weather concerns during the afternoon, mostly for the Sierra
  Front and eastern Lassen County.

* As we head into the weekend and start of next week, ensembles
  are advertising a larger scale ridge amplifying over the east
  Pacific/Pacific Northwest. Meanwhile, a weak upper low undercuts
  the high and slowly pushes into California. With synoptic
  warming, temperatures will increase back above seasonal averages
  by Friday. We`ll also have a return of the Zephyr winds each
  afternoon. -McKellar

.AVIATION...

* VFR conditions continue along with light and VRB winds. Winds
  become generally from the north and east with speeds up to 10
  kts and gusts up to 20 kts after 18Z. Winds subside around 03Z.
  Storm chances continue around 10-20% for Sierra terminals this
  afternoon and tomorrow.

* There is less than 10% chance for FG/FZFG through 15Z for KTRK.
  Chances for FG may increase tonight, if rain or storms develop
  in the Martis Valley this afternoon. -HC/McKellar
