Area Forecast Discussion
National Weather Service Elko NV
226 PM PDT Tue Aug 22 2017

.SYNOPSIS...Isolated to scattered thunderstorms today through
Wednesday evening over much of northern and central NV. Dry and
storm-free over most of the region Thursday through the weekend.
Well above normal temperatures this weekend into next week.


.SHORT TERM...This evening through Thursday afternoon. Storm
motion today has been relatively slow, generally moving south to
north or northwest, with most all of the activity through 2 pm
being over White Pine County and the far northern portion of Nye
County. Radar estimates a few locations across central NV have
received a few tenths of an inch of rain in storms today.

Thunderstorm activity is expected to drift slightly north into
this evening, sitting largely over the central portion of the CWA,
generally between highway 50 and I80. Some lingering nocturnal
storms will be possible over and near southern Elko and Northern
White Pine Counties tonight. Drier air pushes in from the south on
Wednesday resulting in lower precipitable water and dewpoint
values. Most storm activity will be isolated in coverage Wednesday,
however the eastern half of Elko County should see scattered
coverage through the late afternoon, with storm activity
decreasing into the evening hours. Most of western NV will see a
continued influx of dry air Wednesday night into Thursday, with
some isolated showers and possibly thunderstorms over far eastern
Elko County into Thursday afternoon.

.LONG TERM...California upper low is forecast to open and further
weaken through midweek. This will allow a drier
west/southwesterly flow of air to push moisture out of all but far
northeastern Nevada where it will linger across portions of
northern and eastern Elko County on Thursday into Friday. A
stronger tropical system will develop over the western Gulf of
Mexico and impact the Texas coast Friday into Saturday while a
powerful extra- tropical low remains over the Gulf of Alaska.
Subsequently, these two feature will help to build a strong, and
fairly stationary upper level high pressure system over the Great
Basin later in the weekend which will become the dominant
influence on our weather for much of next week. As a result,
northern and central Nevada will experience several days of above
normal temperatures with dry conditions. Afternoon maximum
temperatures will climb back up into the 90s in the lower valleys
with a few of the normally hot spots making a late summer run
into the upper 90s to around 100 degrees.


.AVIATION...Shortwave trough with band of moisture and some
elevated instability will lift north/northwestward from central
into northern Nevada later this Tuesday afternoon and evening.
Will keep the possibility of isolated to scattered thunderstorms
continuing after dark with VCTS at KWMC and KEKO until 06Z.
Activity expected to end toward or before 03Z at KELY with quiet
WX anticipated at KTPH.


.FIRE WEATHER...Showers and thunderstorms will continue to push up
into central and portions of northern Nevada into this evening.
These storms will likely be a mix of wet and dry, however with
fairly high dewpoints and precipitable water values, expect storms
to lean toward the wetter side. Some isolated thunderstorm
activity will be possible overnight over southern and far eastern
Elko County, along with the northern portion of White Pine County
and possibly as far west as Eureka County. Drier air on Wednesday
is expected to lead to a mix of isolated to scattered wet and dry
thunderstorms. The area with the most storm activity Wednesday
will be zones 469 and 470, where storms are expected to be lean
toward the drier side. A RFW is in effect for these two zones.
Warmer and drier conditions Thursday on into next week with well
above normal temperatures.


Red Flag Warning from 11 AM to 9 PM PDT Wednesday for Eastern
Elko County-Southwestern and Central Elko County.
