.SYNOPSIS...Upper level troughing over much of the Intermountain
West will continue unsettled weather with scattered snow showers
into this evening, slowly diminishing in coverage tonight. Much of
the same into Thursday as the trough remains over the region. High
pressure looks to build across the West into this weekend and
early next week with much warmer temperatures set to arrive.

&&

.SHORT TERM...Tonight through Thursday night

Upper-level troughing continues to amplify across the West as a
shortwave digs southward across California and feeds the long wave
trough. Expect fairly similar conditions to yesterday with below
normal highs in the upper 30s and lower 40s and scattered snow
and/or graupel showers as weak instability increases once again
through the rest of the afternoon thanks to steep mid-level lapse
rates in association with the anomalously low 500 mb heights with
the long wave trough directly overhead. Hi-res guidance keeps
these showers slightly less organized than yesterday, but continue
to monitor conditions, especially on roadways this afternoon as
conditions can deteriorate rapidly with stronger snow showers or
squalls. Light snow can quickly accumulate on area roadways with
abrupt drops in visibility. Greatest confidence in accumulations
on roadways will be over passes and summits, particularly along US
93, 50 and 6, along with NV 225 and I-80 with a 40-50% chance for
at least an inch of snow through Thursday morning.

Snow showers should gradually taper off through the overnight as
the atmosphere stabilizes, but any melting snow will likely freeze
unless roadways are fully treated. Hi-res guidance keeps the snow
showers going longest across northern Elko County with localized
minor impacts.

The main long wave trough axis shifts slightly to the east into
Thursday, which leads to less instability and slightly warmer
high temperatures in the mid to upper 40s, though still well below
normal for this time of year. Another round of scattered snow and
graupel showers, though more isolated in nature than today with
lower instability.

.LONG TERM...Friday through next Wednesday
Light snow showers in parts of northeast and eastern Nevada will
dissipate early Friday morning. Dry weather and warming
temperatures expected for the rest of the day and this weekend as
high pressure moves into our area. Highs will reach the 60s by
Sunday. On Monday, a shortwave trough will move through northern
Nevada, bringing slightly cooler temperatures and a chance for
light precipitation in that part of the state. The trough will
exit our area by early Tuesday morning, and dry weather will
return for the rest of the week as a stronger ridge moves in and
expands over the southwest United States. Temperatures will warm
even more, reaching the 70s by Wednesday. Winds will be light
throughout the forecast period.

&&

.AVIATION...Similar conditions to yesterday afternoon at area
terminals this afternoon with scattered snow showers and graupel
showers through 03Z. Low confidence on coverage and timing of
showers, though brief VSBY and CIG restrictions will likely
accompany the stronger showers this afternoon, likely
necessitating a few TEMPO groups as showers attempt to organize
and drift from north to south. North-northwest winds from 5 to 10
kt, shifting more to the northeast after 03Z, then trending back
to the north-northwest after 13Z Thursday morning.

Added AMD NOT SKED to KTPH TAF due to unreliable wind readings
from the ASOS.
