Area Forecast Discussion
National Weather Service Reno NV
311 PM PDT Sat Jun 23 2018

.SYNOPSIS...

Hot and dry weather continues, high temperatures remain 5-10
degrees above average with the hottest temperatures expected early
next week. Light winds are forecast the next couple days with
stronger afternoon breezes returning on Monday.

&&

.SHORT TERM...

Hot temperatures, light winds, and clear skies remain in the
forecast through the rest of the weekend. By tomorrow, winds will
be pretty calm for much of the day as ridging pumps up over
CA/NV. The light winds will make it feel even hotter tomorrow,
since we won`t have the benefit of our typical afternoon summer
breeze.

Temperatures will climb another few degrees again on Monday. This
will be the hottest day of the week with highs reaching into the
upper 90s across western Nevada and 80s in the Sierra. A few
locations out in the Lahontan and Humboldt basins will see
temperatures into the low 100s. In addition to the hot temperatures
will come very dry humidity into the single digits. Low pressure
moving into the Pacific Northwest will increase the west-east
temperature gradients, bringing stronger than normal zephyr wind
with gusts to near 30 mph. Gusty afternoon winds may lead to
localized critical fire weather conditions in northwest Nevada on
Monday. Please see the Fire Weather Discussion below for more
details. Also, choppy conditions may be possible late in the
afternoon for Tahoe and Pyramid as well.

Temperatures will drop a couple degrees on Tuesday, but still
remain well above normal. Typical afternoon zephyr winds are
expected Tuesday with gusts around 20-25 mph. -Hoon

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

Warm and dry weather is expected for Wednesday with a clear sky
due to zonal flow aloft. Winds will pickup during the afternoon
hours just ahead of a fast moving shortwave trough that will push
through the region on Thursday.

The weather pattern gets a little interesting for the end of next
week with regards to a potential low towards the north that could
impact western NV. Global models are still not in a good agreement
with this system. The GFS is more aggressive setting up a closed low
over the Pacific NW by Friday night eventually digging further south
into eastern NV on Saturday. In contrast, the EC has a less
amplified trough moving through rather quickly and keeping precip
chances well to the north. Even though confidence in the placement
and progression of the low pressure trough is low at this time, it
is likely that Friday/Saturday afternoon high temps will lower to
near normal along with an increase in cloud cover and northerly
winds regardless if a low pushes south or not.

This active pattern looks to continue beyond next week with another
chance for low pressure to impact the region. -LaBoom

.AVIATION...

High pressure, resulting in VFR conditions, will continue to
dominate the Sierra and western NV through Sunday. A clear sky and
breezy northerly winds should be expected while under the ridge.

The ridge begins to slide towards the east by Sunday night as an
upper level trough approaches. Expect WSW winds to increase for
Monday afternoon with gusts around 30 kts becoming lighter and
northwesterly by nightfall. -LaGuardia

&&

.FIRE WEATHER...

A hot and dry pattern continues into early next week with triple
digit heat possible for western Nevada Basin and Range valleys.

Fire weather concerns look to occur on Monday where dry conditions
and increased wind gusts are expected due to an area of low pressure
passing across the Pacific Northwest. Wind gusts look to range in
the 25-35 mph range with the strongest of these gusts concentrated
roughly north of Highway 50 and through the I-580/Hwy 395 corridor.
This will likely produce some isolated areas of Red Flag conditions,
however widespread, long duration critical fire weather conditions
are looking marginal at this time and will just headline for dry and
gusty conditions for Monday.

Dry conditions remain through mid-week with more typical afternoon
zephyr breezes expected.  Fuentes
