Area Forecast Discussion
National Weather Service Reno NV
123 AM PST Sun Jan 19 2025

.SYNOPSIS...

* A brief cooldown later tonight into Monday with gusty winds
  across ridges.

* Dry conditions all week, with a chance at increasing winds,
  showers, and cold temperatures arriving for next weekend.

&&

.DISCUSSION...

* A quick moving system will move through the area later tonight
  into Monday. For today, we`ll see above seasonal temperatures
  and light winds. However for Monday, the atmosphere will remind
  us that it`s January as temperatures tumble 10-15 degrees. We`ll
  struggle to get to 40 degrees in western NV and 30 degrees for
  Sierra communities. In addition to the cold temperatures, east
  to northeast winds will increase upwards of 60-80 mph on
  ridges, with up to 35 mph on Lake Tahoe. This system has no
  precipitation, and the airmass moving into the region is very
  dry (PWATs less then 0.10").

* High pressure builds back into the area Tuesday through
  Thursday. Temperatures warm back up to average for Tuesday and
  Wednesday, then above average by Thursday and Friday. As per
  usual, inversions with poor dispersion will return to the
  region.

* Model ensembles are hinting that by Friday, the ridge breaks
  down with a trough pattern returning to the western US.
  Ensembles are still struggling on the exact path and strength of
  the trough, with some solutions giving us precipitation with
  others dry. There is higher confidence that we`ll see another
  drop in temperatures and increased winds along the ridges.

.AVIATION...

* VFR conditions at all western Nevada and Sierra terminals. Winds
  will increase from the NW this afternoon/tonight with gusts
  upwards of 20 kts.

* Ridge winds will increase later tonight into Monday, with
  maximum gusts to 55-65 kts. This will introduce some LLWS and
  mountain wave turbulence along and west of the Sierra crest
  tonight and Monday. -McKellar
