Area Forecast Discussion
National Weather Service Reno NV
306 AM PDT Sun Oct 22 2017

.SYNOPSIS...

Drier air moves into the region as high pressure builds across the
region. Warmer conditions are expected for the rest of this weekend
and next week as temperatures increase well above seasonal
averages.

&&

.SHORT TERM...

Only a few clouds remain north of Pyramid Lake as the jet stream
retreats northward, likely for the duration of the month. A ridge
of high pressure builds directly over the western U.S. the next
few days. This will allow temperatures to continue to warm a few
degrees a day through midweek when temperatures in the valley will
reach back to near the 80 degree mark.

Mostly light easterly winds are expected the next few days with a
few stronger breezes possible near the Sierra crest Monday as
surface gradient along the west slope of the Sierra strengthens.
Moderately strong inversions are expected to continue as warm air
continues to move in aloft. -Zach


.LONG TERM...Wednesday through Saturday...

Minimal changes were made to the inherited extended forecast this
cycle. The medium range operational models are trending a bit
weaker and farther east with the next short wave to drop across the
region. This means less chance for increased clouds and winds for
western Nevada and eastern California.

Well above average daytime temperatures Wednesday will give way to a
fast moving...mainly dry...short wave and surface cold front by
Thursday morning. While the core of the cooler air is trending
farther east into the Intermountain West...we should see a dip in
highs for Thursday and Friday. Gusty east to northeast winds are
still possible over the ridges Thursday morning...but not as strong
as previous simulations showed.

Ridging aloft and at the surface begins to redevelop by early
Saturday with rising heights aloft and warming surface temperatures.
Light winds are likely for Friday and Saturday in most valleys
with inversions developing each night.

&&

.AVIATION...

VFR conditions area wide outside of KTRK where freezing fog
will persist through 0900 local. Light easterly winds are
expected through Tuesday afternoon. Winds over the crest could
reach near 40 kts for a time Monday evening as the surface
gradient strengthens. Easterly winds will also bring drier air to
the region and lessen the chances for fog at KTRK, but it will
continue to remain possible each morning. -Zach
