Area Forecast Discussion
National Weather Service Reno NV
232 AM PDT Thu Jun 29 2017

.SYNOPSIS...

High pressure off the west coast will gradually build inland through
Friday, keeping dry conditions over the region. Temperatures
will slowly warm up through this weekend, and remain above average
through the July 4th holiday. Mainly light winds are expected
through the upcoming week, except for typical afternoon and
evening breezes.

.DISCUSSION...

High pressure anchored in the eastern Pacific will keep the storm
track well north of the region towards southern Canada for the
near future. A trough will pass north of the Oregon border likely
resulting in a slight strengthening of the afternoon zephyr.
Otherwise, temperatures trend warmer will little to break stagnant
conditions over the southwestern United States. The next 100
degree highs can be expected over the weekend.

Later next week, models are indicating that a very strong, 600+
decameter on the 500mb pressure surface, ridge will develop over
the Four Corners region. This pattern usually means an increase in
temperatures for western Nevada and the Sierra while moisture
aloft slowly increases. As such, we could be adding chances of
thunderstorms for later next week over the next day or so.

Looking beyond seven days: Model trends have been showing a
retrogression of next week`s increasing ridge of high pressure.
This would allow for heat to build further over western Nevada
and the Sierra. These early signals seem to be pointing to the
potential for the next heat wave. Daily highs along the Sierra
Front could potentially exceed 100 degrees to around 105 for more
than a couple of days under these conditions with low/mid 90s
possible for Sierra valleys. This, of course, is all predicated
upon how far west the high shifts; a situation that will be
watched closely over the next week. Boyd

.AVIATION...

VFR conditions persist through the weekend into next week while
local terminals experience typical afternoon wind patterns.
Maximum gusts will be fairly light, around 20kts or so, heading
into the weekend. A weak passing wave could increase gusts a
little, Sierra Front terminals could see up to 30 kts, Sunday and
Monday afternoons. Boyd
