.SYNOPSIS...There may be a few thunderstorms with gusty winds
around eastern Nevada this evening. Temperatures will cool off a
little in the coming days as low pressure brings more moisture to
the Great Basin over the weekend.

&&

.SHORT TERM...Tonight through Saturday. The models seem to be in
very good agreement for the short term period. A 50 mile wide
swath of cumulus began developing around noontime, stretching from
along highway 50 in southern Lander County to Wendover, but no
lightning strikes in Nevada or UT thus far. With low pressure to
our northwest, satellite imagery shows some mid-level clouds
passing over northern Nevada, helping to keep convection potential
low. There is a risk for some thunderstorm activity to linger
through the night tonight then coverage will increase for Friday
and Saturday with more wetting storms expected.

Tonight through Friday morning. A low pressure system will begin
dropping south from Canada with central low pressure north of the
border through Friday morning. Isolated dry-variety thunderstorms
are expected to affect mainly areas east of the Ruby Mountains and
just a sliver of White Pine, northern Nye and southern Lander and
Eureka Counties. Isolated thunderstorms will be possible across
White Pine County and southeast Elko County through the night but
should dissipate early Friday morning. Low temperatures will range
from the mid 40s to the mid 50s.

Friday afternoon and evening. Latest model guidance insists that
the trough axis will not move from its position along the CA/NV
border. The GFS model shows an imbalance of energy in the jet
core on the west side of the developing trough. This 105kt jet
feature moving south across Oregon will lead to additional
digging of the trough and/or a positive tilting of the upper low
feature. The lee side jet core will dip into northern Nevada by
late afternoon or early evening and give some lift. Areal coverage
of convection will increase and storms should be a little wetter,
especially north of Interstate 80. Most areas will be prone to
getting thunderstorms and the southern half of the LKN CWFA will
still experience dry-variety thunderstorms. High temperatures
will be in the 80s.

Midnight Friday through Saturday. Low pressure will meander near
the northern CA/NV border. Precipitation chances will be higher
north of Interstate 80 with more wet-variety storms expected. Low
temperatures will be in the 40s. High temperatures will be in the
70s.

.LONG TERM...Saturday night through next Thursday.

A closed low centered in the vicinity of northern Nevada will be
moving very little through at least Monday, bringing periodic
chances for showers and thunderstorms.

Best moisture and POPs will exist over northern parts of the
state while drier conditions will exist farther south across
central areas, though showers and isolated dry thunderstorms are
still possible there.

Global models diverge some from Tuesday through Thursday, with the
GFS keeping the closed low close enough to Nevada to continue the
shower/thunderstorm activity while the EC lifts the low further
north, limiting precipitation chances closer to the NV/Idaho
border. Forecast confidence past Monday is therefore lower for the
middle of the week.

High temperatures will be cooling with the low nearby, about 5-10
degrees below normal, while low temperatures will remain closer to
normal.

&&

.AVIATION...VFR conditions continue all sites through Friday. West
to southwest winds expected Friday afternoon and evening, strongest
at KELY where gusts could exceed 30 kts at times.

&&

.FIRE WEATHER...Isolated dry thunderstorms will be possible this
evening, mainly east of the Ruby Mountains with a strike or two
possibly continuing overnight in FWZ455. There is a low pressure
area moving into the western U.S. at this time but indications
are that it will not move into Nevada until Sunday night. However
moisture will begin to increase on Friday with some storms
becoming wet, especially north of Interstate 80. Wind gusts on
Friday afternoon will exceed 30 mph across most of central Nevada
due to the advancing trough where humidity will still drop below
15% for the most part during the day. The low pressure trough will
move through the state Sunday night and Monday. Showers will
mainly affect the northern half of the state.

.LKN WATCHES/WARNINGS/ADVISORIES...
None.
