Area Forecast Discussion
National Weather Service Elko NV
238 PM PDT Tue Jul 25 2017

.SYNOPSIS...The weather will remain active through the evening
tonight. Some storms may be strong and could produce brief
moderate to heavy rain. Drier air will start to move in tomorrow,
bringing with it lessening storm chances.

&&

.SHORT TERM...Tonight through Friday. Convective activity is
getting a slow start this afternoon as high temperatures are
cooler today than what they were yesterday. Many readings were
about 7-10 degrees cooler and thus have delayed the convection.
Storms are not moving too fast with 700-500mb speeds progged at
around 5 knots or so. The showers and storms will continue to form
through the afternoon and evening hours per the latest HRRR runs.
In addition, we have seen some training storms in northern Nye
county, and the possibility does exist further north. Still
concerned about heavy rain on recently created burn scars. Based
on these factors, will keep the flash flood watch going at this
time. Overnight lows will be in the 50s for the most part.

All model solutions are showing the closed upper level trough off
the California coast slowly shifting to the northeast. There will
continue to be a jet max over the northern parts of the forecast
area. It looks like another active day across the region. Storm
motions will be a little quicker at 10-15 knots. But precipitable
water values are expected to be down slightly, with many locales
coming in around 0.75 inches or so. The highest readings will be
in the eastern spots along the border with Utah. High temperatures
will be in the low to mid 90s. Winds will be light.

Wednesday night into Thursday. The upper trough energy will shift
east. Southwest flow will bring some drier air into the area, with
precipitable water values decreasing to 0.66 to 0.75 inches. Will
need to see how much drier air will be over the area. Have kept
isolated showers and thunderstorms in the forecast as model
solutions typically are too quick with removing the moisture.
Highs will be in the low to mid 90s with light winds.

Thursday night into Friday. Drier air continues to move into the
area. Have limited thunderstorm coverage to isolated only.
Afternoon highs will be in the low to mid 90s again.

.LONG TERM...Friday night through next Tuesday.

Upper ridge will gradually rebuild over the Great Basin this
weekend into early next week. Lingering moisture and weak
instability under this feature will result in a chance of isolated
thunderstorms across portions of central and eastern NV each day.
ECMWF is more aggressive and quicker to build a closed upper high
right on top of Nevada by early next week which would lead to an
overall hotter and drier solution. GFS has slowly rising heights
through the weekend while bringing some monsoonal moisture back
into southern and central parts of the state later Sunday into
Monday. Eventually, the GFS does build a closed high back over
southern California during the later half of next week while
keeping some moisture in place over Nevada. Overall, will lean
toward the GFS solution with above normal temperatures likely for
the balance of next week.

&&

.AVIATION...Scattered showers and thunderstorms will redevelop
this afternoon around and en route of all TAF sites given
available monsoonal moisture and instability. Scattered storms
will persist through mid-evening before diminishing to pockets of
light rain later this evening/overnight. Outflow winds over 30
knots, locally heavy heavy downpours and small hail along with
reduced visibilities to at least MVFR are likely in the vicinity
of stronger convective cells this afternoon and early evening.
Cannot rule out the possibility of an isolated severe gust/wet
microburst to 50 knots associated with a more intense descending
storm core.

AMD NOT SKED will continue for KWMC until further notice due to
comms line issue.

&&

.FIRE WEATHER...Scattered to numerous showers and thunderstorms
will continue this evening across all zones. Some of these storms
can produce brief heavy rain and strong gusty outflow winds.
Localized flash flooding and strong to severe storms are still
possible and remain the main threats. Additionally, awareness of
recent burn scars for the potential of flash flooding and/or
debris flows in and around recent burn scars is critical and will
be monitored closely. This active pattern will diminish towards
the end of the week.

&&
