Synopsis
Mid-summer heat will persist across the sierra and western nevada
for the upcoming week. The threat for mainly afternoon and evening
showers and thunderstorms continues for the next few days. A couple
strong storms are possible with frequent lightning, locally heavy
rainfall, gusty winds and small hail. Lightning could also occur
late tonight into early Tuesday for parts of western nevada.

Discussion
* thunderstorms
another day of thunderstorms is expected late this afternoon and
early evening with potential for storms to sustain into the overnight
hours. There is concern for both dry lightning strikes as well as
the potential for a few strong thunderstorms with isolated heavy
rain, gusty erratic winds, and hail up to around an inch possible.

The main focus of thunderstorms is expected to be in west-central
nevada and with west winds starting to kick in as of 2 pm it looks
unlikely that we'll get storms to form as far west as reno carson.

Storms are expected again on Tuesday, most likely well east of
reno-carson as drier air pushes into the region from the west.

For mid-week, storms are expected to be mainly confined to south
of i-80 as a trough swings through the pacific northwest and
increases dry southwest flow for the northern parts of the region.

Storms could become more widespread again late in the work week
as the ridge of high pressure builds into the desert southwest.

It looks like dry air will dominate by the weekend with thunderstorms
becoming unlikely.

* heat
today is expected to be the hottest day of the workweek with daytime
high temperatures in the 90s to low 100s. The low temperatures
overnight are also going to be unusually high, only dropping down
to the mid 60s to around 70. This brings a moderate risk of heat
health impacts, especially for those who are sensitive to heat,
and those without effective cooling. A heat advisory is in effect
through this evening for western nevada.

Temperatures will cool a few degrees for the rest of the week,
but not a lot. Expect heat to continue through the week, possibly
re-intensifying by the weekend with another chance for triple
digit temperatures.

* winds
typically breezy winds are expected in the late afternoons through
the week, generally gusting to around 25-30 mph. For more information
on this may impact fire weather refer to the fire weather section
below.

Aviation
Hot temperatures with thunderstorms and typical afternoon breezes.

Temperatures near 95-100 degrees will increase density altitude
concerns through the rest of the week.

Thunderstorm are expected throughout the region today with the
greatest likelihood in west-central nevada. Chance of thunderstorms
at ktvl ktrk = 5-10%, krno kcxp kmev =10-15%, kmmh = 15-20%,
knfl klol = 25%. There is a chance of a few discrete super cells
in west-central nevada with hail up to 1 inch, brief heavy rainfall,
and wind gusts in excess of 60 mph.

Outside of thunderstorm wind gusts, mainly typical afternoon
breezes out of the west gusting 20-25 kts. -zach

Fire weather
Thunderstorms have been slow to develop this afternoon, with west
winds kicking in early to squelch instability focus across far
western nevada and northeast ca. Farther east from the pine nut
range eastward, isolated thunderstorms remain possible through the
evening, with gusty and erratic outflow winds in excess of 40 mph
possible with surface temp dewpoint spreads in excess of 50 degrees.

Wetting rains are unlikely due to fast storm motions.

A few nocturnal storms are still possible tonight from the sierra
front up into northwest nevada, and perhaps as far west as the
lake tahoe basin. Any nocturnal storms will be fast moving, greatly
limiting how much rain will reach the surface in any one spot,
additionally, the very high bases will bring a low chance for a
few sudden surface gusts to 30-35 mph late tonight and Tuesday
morning. As there is no major, organized forcing aloft, coverage
and confidence are expected to remain low enough that watches or
warnings were decided against.

As far as winds, heads up across northeast california and into northern
washoe county where afternoon wind gusts of 25-30 mph (briefly to 35
mph in some spots) are expected again Tuesday afternoon.

Additional afternoon storms are possible Wednesday through Friday,
although the focus will shift to the more typical mono-mineral areas.

Also, moisture will increase with lighter flow aloft allowing for
more rain to reach the surface. In fact, flood prone areas such
as burn scars could see an increased chance for flash flooding if
heavy rain sets up over those areas. -snyder
