Area Forecast Discussion
National Weather Service Las Vegas NV
1140 AM PDT Mon May 11 2020

.SYNOPSIS...Dry and windy weather will remain the main story for
the first half of the week resulting in fire weather concerns,
especially for northwest Arizona. Expect a downward trend in
temperatures through Wednesday then a slow warmup heading into the
weekend. Beyond the weekend, a possible shortwave disturbance
early next week should keep temperatures from increasing, and
perhaps more wind/fire concerns.

&&

.SHORT TERM...through Tuesday.
The main concern through the short term period is winds and fire
weather concerns through Tuesday. A Red Flag Warning just went
into effect for much of southern Nevada and northwest Arizona
which originally was just for the low RH and windy conditions
expected today but some elevated dry T is also on the table the
rest of the afternoon east of the Colorado River. Added this to
the grids and to the current RFW.

Elsewhere, a rather impressive downslope wind gust scenario looks
possible later this evening and overnight tonight for the Owens
Valley, but also the Spring Mountains. Currently, the latest hi-
res trends seems to all key in on strong downslope wind gusts,
potentially over 50 mph for locations such as Red Rock Canyon and
possibly west sides of the Valley. In these types of set up, this
also results in strong crosswinds across Highway 95 including
Indian Springs and Desert Rock. We will continue to assess through
the afternoon, but may need to include parts of Clark and Nye
counties into a Wind Advisory for this evening with similar times
as that of the Owens Valley. Additionally, after the atmosphere
decouples through the mid morning, near advisory criteria winds
look likely across San Bern and Clark/Mohave tomorrow afternoon.
At a minimum, another RFW looks likely for Arizona fire zones and
possibly a Wind Advisory for zones to the west.

.LONG TERM...Wednesday through the weekend.
The latter half of the week looks more benign from a wind
perspective as a brief period of ridging sets up over the west
coast ahead of the next potential disturbance early next week.
This should serve to keep winds below critical fire thresholds,
and with the cooler mid to late week temperatures, RH should stay
at or slightly above critical thresholds. As the ridge axis
maximizes by Saturday, highs climb back into above normal
territory. However, another Pacific trough is progged to evolve
into a progressive shortwave early next week that could serve to
temper highs and bring more wind/fire concerns to the region.
Ensemble analysis indicates that the bulk of the intermodel
variance is explained by a more progressive and deeper shortwave
than currently illustrated in the means so this would add more
credence to those concerns for potential impacts as well.

&&

.FIRE WEATHER...Increasing southwest winds today will lead to
widespread critical fire weather conditions from late this
morning into this evening. A Red Flag Warning went into effect
for a large portion of southern Nevada and northwest Arizona from
this morning until 8 PM PDT. Southwest winds gusting between 30
and 40 mph will pick up again Tuesday afternoon across San
Bernardino, Clark and Mohave counties. However, temperatures will
drop 6-10 degrees across the region and dewpoints will increase
which will result in minimum relative humidity near or above 15
percent for much of the region and slightly lower fire danger for
Nevada fire zones. Northwest Arizona may still warrant an
afternoon RFW however, especially with ongoing fires in those
areas.

&&

.AVIATION...For McCarran...Gusty southwest winds expected today and
tomorrow across the region. Expect sustained winds of 15-20 knots
this afternoon with gusts to around 25-30 knots. Winds overnight are
expected to remain elevated with gusts to 20-25 knots. There is the
potential for downslope winds off the Spring Mountains to push into
the valley overnight, generally after 06Z-12Z, but confidence is low
that these winds will reach KLAS. By 13-14Z tomorrow morning,
stronger winds should sweep across the valley with winds of 20-25
knots and gusts to 30-35 knots possible tomorrow afternoon.
Outside of the winds, minimal aviation impacts are expected with
dry conditions and SCT-FEW clouds above 20kft.

For the rest of southern Nevada, northwest Arizona and southeast
California...Gusty southwest winds expected across the region this
afternoon through tomorrow. Strongest winds will be across a broad
area along the I-15 corridor. Gusts expected this afternoon should
generally be 20-30 knots, with slightly stronger winds expected at
KDAG to 35 knots. Downslope west winds are expected in the Owens
Valley overnight tonight with gusts reaching to 40-45 knots near the
western foothills. Low confidence these winds reach KBIH overnight
though, where only westerly gusts to 25 knots are expected with the
potential of gusts dropping off completely overnight. Elsewhere,
winds should generally remain elevated overnight. Winds will quickly
become gusty again by tomorrow morning around 14-15Z, with gusts to
25-35 knots expected across much of the region through the
afternoon. Outside of the winds, minimal aviation impacts are
expected with dry conditions and SCT-FEW clouds above 20kft.

&&

.SPOTTER INFORMATION STATEMENT...Spotters are encouraged to report
any significant weather or impacts according to standard operating
procedures.
