.DISCUSSION...

Very warm and dry weather prevails through the week with daytime
highs in the 70s and 80s areawide. Residual high Sierra snowpack
will continue to melt amid our June-like warmth, resulting in
regional streamflows running fast and very cold.

A weak trough tandem will increase winds Thursday and Friday,
inducing travel, recreation, and fire weather impacts (see Fire
Weather discussion below) leading up the holiday weekend. If you
plan on traveling for the long weekend, be prepared for bumpy
flights into/out of regional airports, difficult driving
conditions along N-S oriented roadways (e.g., I-580 near Washoe
Valley, US-95 near Walker Lake, US-395 near Honey Lake), and
reduced visibilities due to blowing dust across the Basin and
Range. Hazardous boating conditions are also likely on area lakes,
including Lake Tahoe and Pyramid Lake Thursday and Friday
afternoons. A few showers or stray thunderstorm will be possible
near the Oregon Thursday and Friday afternoon with dry weather
prevailing elsewhere.

Very warm or, dare I say, hot temperatures remain favored for the
holiday weekend, especially Sunday and Monday as high pressure
overspreads the region. As such, area creeks and streams will look
very enticing to cool off in, but remember that the prolonged warmth
will mean streamflows will be running fast and very cold so be sure
to avoid jumping in!

.AVIATION...

Widespread VFR conditions and light afternoon breezes prevail
through Wednesday. Gusty winds return Thursday, increasing the
potential for LLWS and mountain wave turbulence impacts during a
busier travel period ahead of the holiday weekend.

.FIRE WEATHER...

A multi-hour period of elevated to critical fire weather conditions
is likely Thursday and Friday afternoon across much of western
Nevada where west to southwest gusts of 30-40 mph overspreads
afternoon RH`s of 7-15%. Very warm and dry weather continues into
the weekend, but winds are expected to be lighter.

While a lack of prominent fuel intel will preclude the issuance of
any products, a report from the Great Basin GACC did reveal that we
remain in green-up with curing cheatgrass.
