Area Forecast Discussion
National Weather Service Las Vegas NV
729 PM PDT Thu Jun 30 2022

.SYNOPSIS...Another day of isolated thunderstorm activity expected
for eastern Mohave County today before dry air moves into the
region. Troughing will bring gusty south-southwest winds this
holiday weekend, resulting in increased fire danger for southern
Nevada and northwestern Arizona. Otherwise, temperatures will drop
below average for the start of the work week, slowly increasing into
next weekend.
&&

.Update...Showers and isolated thunderstorms continue to dissipate
this evening and should end by 9 PM with mostly clear skies expected
overnight. We can expect to see another day of isolated afternoon
and early evening showers and thunderstorms mainly across northern
Mohave County as drier air begins to work in from the west. This
will bring breezy to windy conditions over the weekend along with an
increase in fire weather concerns.
&&

PREV DISCUSSION
137 PM PDT Thu Jun 30 2022

.DISCUSSION...Today through next Thursday.

One more day of isolated convection expected across portions of
Mohave County this afternoon. PWATs upward of an inch continue
across the western Mojave Desert, extending as far north as the
Arizona Strip. Despite numerous days of isolated-to-scattered
convection in the area this week, the low levels of Mohave County
remain dry, as shown by forecast inverted-V HRRR soundings. CAPE
values in northern Mohave are modest, around 250 J/kg, with DCAPE
between 1000 and 1500 J/kg. As such, gusty winds will be the primary
threat from storms that develop, but isolated flash flooding cannot
be ruled out, particularly in the event of training storms. PWATs
will be quick to retreat through the day on Friday as the monsoonal
high shifts eastward.

The primary focus of the forecast period becomes an incoming dry
trough that will enhance fire danger across southern Nevada and
northwestern Arizona through Independence Day weekend. In general,
skies will be clear and temperatures will be a few degrees below
seasonal normals, making for a seemingly pleasant (respectively)
Independence Day weekend. However, due to the incoming trough, ECMWF
EFI shows seasonally abnormal winds picking up across the southern
Great Basin this weekend. These gusty south-southwest winds will
pick up through the day on Saturday, with sustained winds around 20
mph and gusts to 35 mph. Winds will peak on Sunday, with gusts 30-40
mph across southern Nevada and northwestern Arizona. Lincoln County,
Nevada will experience the strongest winds on Sunday, with gusts to
45 mph possible as the closed low associated with this trough pushes
inland. Finally, south-southwest winds return on Monday with similar
speeds as Saturday. As such, a Fire Weather Watch has been hoisted
for southern Nevada and northwestern Arizona from Saturday morning
through Monday evening due to strong winds, afternoon relative
humidities in the lower-teens to single-digits, and increased
firework activity. Outdoor burning and firework usage is not advised
in these areas due to the increased chance of wildfire starts and
spread.

Otherwise, temperatures will bottom out on Monday with 4-6 degrees
below seasonal normals as the trough moves northeastward out of the
region. Heights will rise through the remainder of the week as
ridging builds back into the Desert Southwest, with temperatures
above-average going into next weekend.
&&

.FIRE WEATHER...Increased fire danger expected this weekend due to
an influx of dry air from an incoming trough. Gusty south-southwest
winds across southern Nevada and northwestern Arizona will pick up
Saturday, peak Sunday afternoon, and gradually diminish on Monday.
Strongest winds will focus in the southeastern Great Basin. Coupled
with afternoon relative humidities in the single-digits to upper-
teens, there will be increased chances of wildfire starts and
spreads. Fire Weather Watch in effect Saturday morning through
Monday evening. Outdoor burning and firework activity during this
time is ill-advised.
&&

.AVIATION...For Harry Reid...South southwest winds gusting around 25
knots will settle down to around 10 knots sustained after sunset.
There could be a short period of southeast winds Friday morning
before the gusty south southwest winds return around midday.
Slightly stronger gusts are expected Saturday with the strongest
gusts likely Sunday. No operationally significant clouds or weather
expected.

For the rest of southern Nevada, northwest Arizona and southeast
California...Aside from isolated thunderstorms in eastern Mohave
County this afternoon and early evening, dry weather is expected
areawide through the weekend. Southwesterly breezes are expected
each afternoon and evening, with gusts 20 to 25 knots Friday
afternoon increasing a few knots Saturday afternoon and a few more
knots Sunday afternoon, which is expected to be the strongest wind
day.
&&

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

UPDATE...Gorelow
DISCUSSION...Varian
AVIATION...Morgan
