Area Forecast Discussion
National Weather Service Elko NV
308 AM PDT Sat Jul 6 2024

.SYNOPSIS...High pressure continues to influence the Great Basin
with dry and hot weather persisting. Heat impacts are almost
certain as valley temperatures reach or exceed 100F for many
locales across the western half of the forecast area this weekend
before expanding into eastern Nevada this coming week.

&&

.SHORT TERM...Today through Sunday Night

Gradually expanding and strengthening high pressure over the
western U.S. keeps weather dry under mostly sunny and clear skies
while promoting a warming trend across the forecast area thru
next week. Daytime high temperatures today will be in the low 90s
to low 100s, generally remaining so for Sunday but with
temperatures near or greater than 100 degrees becoming more
prevalent across the western half of the forecast area. Heat
related Watches and Warnings currently remain valid beginning
today, persisting thru the middle of next week. A very dry air
mass in place paired with excellent radiational cooling overnight
promote 40+ degree diurnal temperature swings, bringing some
relief to hot daytime temperatures. Overnight lows reside mostly
in the upper 40s to upper 50s tonight and tomorrow night.

Northwesterly flow will reside over the forecast area today and
tomorrow with an upper disturbance clipping northeast Nevada.
This will produce elevated afternoon northwesterly surface winds
today and tomorrow with gusts generally 25 to 35 mph. The stronger
winds will be focused across Elko County today, but also move
into central Nevada tomorrow. Light to calm conditions overnight
with local drainage winds dominant.

&&

.LONG TERM...Monday through next Saturday

Hot and dry conditions expected to continue throughout the long
term as ensemble models show the high pressure system causing
this upper ridge heat dome to remain over the southwest U.S. well
into the weekend. Above normal temperatures continue with highs in
the 90s to 100s throughout the region with lows expected to be in
the 60s each night with the exception of west Wendover expecting
lows in the 70s. Afternoon southerly/southwesterly winds expected
to elevate each afternoon at 10-15 mph with stronger southwesterly winds
by Saturday at 15-20 mph.

&&

.AVIATION...VFR conditions continue at all TAF sites today. W-NW
winds will gust to around 20kts in most locations this afternoon,
while well above normal temperatures may produce periods of
density altitude concerns.

&&

.FIRE WEATHER...Dry weather and a warming temperature trend will
continue thru next week as high pressure builds over the Great
Basin. A weak upper level disturbance skirts northeast Nevada this
weekend, producing elevated winds. Subsequently, a Red Flag
Warning is in effect for fire weather zones 438, 469, and 470
valid from 11 AM PDT this morning until 8 PM PDT this evening for
sustained northwest winds 15 to 20 mph, with gusts around 30 mph,
and relative humidity less than 15%. Elevated fire weather
conditions are expected elsewhere across the forecast area today
and tomorrow due to northwesterly afternoon breezes with wind
gusts 25 to 30 mph and relative humidity again less than 15%. Hot
and dry weather continues next week though lighter winds are
expected beginning Monday as the high pressure center moves
directly over the region.
