Area Forecast Discussion
National Weather Service Las Vegas NV
930 AM PDT Wed Aug 21 2024

.SYNOPSIS...Another couple of days of monsoon activity is expected
in northwestern Arizona before a trough of low pressure dries out
the region and cools temperatures to below-average readings this
weekend. Meanwhile, gusty southwest winds will pick up Thursday and
Friday afternoons that will increase fire danger across the southern
Great Basin. Temperatures will rebound back above seasonal averages
next week.
&&

.UPDATE...Moisture from the Gulf of California is continuing to
stream northward through the Colorado River Valley this morning. Dew
point temperatures into the low 60s have spread as far north as
Laughlin, and this moisture will continue to spread north and deepen
through the day.  Convection is still expected to be limited this
afternoon and evening, with the best storm chances remaining across
the Arizona Strip.  However, the latest HRRR guidance indicates the
possibility of an isolated storm or two developing over southern
Mohave and far eastern San Bernardino Counties by mid-afternoon.
Given the increasing moisture levels noted above, any storms that do
develop today may contain heavy downpours that could result in
localized flash flooding.

.PREVIOUS DISCUSSION...220 AM PDT Wed Aug 21 2024

.SHORT TERM...Today through Friday.

Thunderstorms returning to Mohave County this afternoon through
Thursday will be the most impactful weather impact for our forecast
area the next few days. This is a result of moisture being pulled up
from northwest Mexico and the Gulf of California between a ridge
centered over Texas and a broad trough extending down from the
Pacific Northwest. Surface dew points in the lower 60s have spread
up the lower Colorado Rive Valley to between Lake Havasu and Needles
and deeper moisture will increase today and tonight then persist
through Thursday across Mohave County with precipitable water values
of 1.25-1.5 inches likely. This will be followed by a drying trend
Friday as dry southwest flow increases.

Isolated to scattered thunderstorms will begin this afternoon over
northern Mohave County and will likely continue overnight and
increase in coverage through Thursday night with the aid of upward
forcing associated with the jet entrance region over Northwest
Arizona and Southwest Utah. Storms will move to the northeast around
20-25 mph, but this setup will be favorable for training cells
Thursday and the potential for localized heavy rainfall and
associated flash flooding especially over far northeast Mohave
County from Colorado City to Pipe Spring National Monument. We will
monitor this area closely through this afternoon through Thursday
night.

The aforementioned trough will strengthen and dig as a closed low
dropping out of the Gulf of Alaska slowly makes its way inland
across the Great Basin and Northern Intermountain Region Friday into
the weekend. This will lead to widespread south-southwest winds
gusting 30-40 mph and dry conditions Thursday and Friday across
southeast California and southern Nevada. Temperatures will begin
trending downward today with high lowering generally 3-5 degrees
each day through Friday.

.LONG TERM...Saturday through Tuesday.

Deep West Coast trough will begin to weaken and swing inland over
the weekend, ushering in dry and cooler air to the region. There
remains some discrepancy among forecast guidance on finer details of
the trough, namely how quickly it weakens and how fast it lifts into
the northern Rockies. But regardless, confidence is high that
temperatures will drop to their coolest levels since Mid-June. NBM
probabilities for a high temperature Saturday of 99 or less are
currently near 75 percent, with about a 40 percent chance of being
95 degrees or less.  Meanwhile, morning low temperatures in parts of
the Owens Valley near Bishop will bottom out in the lower 40s by
Sunday morning. The taste of fall won't last long however as ridging
will begin to build back across the Southwest early next week,
helping to send temperatures back closer to normal by Monday and
Tuesday.

&&

.AVIATION...For Harry Reid...South or southeast winds will continue
through the morning with wind direction favoring 180 to 160 degrees.
There is a 50% chance for wind speeds over 8KT through 15Z, and
current observations at and around the terminals have been 8-10KT
through much of the night so expecting this trend to continue. After
15Z, the probability for over 8KT wind speeds increases to 100% and
there is a 30%-40% chance for gusts of 15-20KT.

After 18Z, winds will become south southwest and increase. Gusts
over 20KT are likely with low chance (30% probability) for gusts
over 25KT, especially around 21Z. Gusts will end after sunset but
southerly wind speeds will remain between 8-10KT through the night.
Watching the potential for southeast winds to push into the
terminals after 12Z with speeds around 10KT, included a shift to a
more southerly direction at 14Z Wednesday however low confidence in
exactly how winds will set up at that time.

Storm activity will increase today compared to the past few days,
however not expecting anything near the terminals this afternoon
with most of the convection remaining in western Arizona, including
the with the Mormon Mesa corridor possibly seeing thunderstorm
impacts.

For the rest of southern Nevada, northwest Arizona and southeast
California...Gusty south to southwest winds will develop late this
morning and early afternoon across the region with widespread gusts
20-25KT expected. KBIH will favor a more southeasterly direction
like they usually do, with gusts likely remain at 20KT or less with
only a 30% probability for gusts over 20KT this afternoon. KDAG will
see gusty southwest winds developing after 22Z. Winds will diminish
after sunset. Low confidence in winds tonight at KEED and KIFP as
south to southeast winds may push out of southwest Arizona through
the Colorado River Valley, which would keep winds elevated and more
southeast than the current TAF forecast. Scattered thunderstorms
will develop this afternoon, mainly in northwest Arizona however
there is a very low chance for thunderstorms further south which
would get close to KEED and KIFP. COnvection may linger in northwest
Arizona through the night. Increasing clouds out southwest Arizona
through the period but will remain around 12kft-15kft.
&&

.FIRE WEATHER...South-southwest winds will increase today then
become stronger Thursday and Friday with gusts 30 to 40 mph. These
winds will combine with dry fuels and single-digit afternoon
relative humidity values resulting in critical fire weather
conditions across most of southern Nevada. Fire Weather Watches are
in effect from Thursday morning through Friday evening. Overnight
relative humidity recoveries will range from 30 to 40 percent across
the watch area.
&&

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