Relatively dry weather pattern is expected today and Saturday as
chances for showers and storms remain primarily across mohave county
and lincoln county. Storm chances increase early next week as next
round of moisture begins pushing across the region on Sunday.
Short term Today through Sunday night.
Debris clouds from earlier thunderstorms over arizona and northern
mexico will send high clouds streaming northward over much of mohave
county today, but with only weak instability and somewhat drier air
at the surface any thunderstorms are expected to generally remain
east of the county, but one or two still can not be ruled out this
afternoon. For the remainder of the region, drier air will work in
from the southwest shifting the main threat of thunderstorms into
lincoln county. The best instability lies over much of lincoln
county and dewpoints still remain fairly high. Although bulk shear
numbers are not too impressive they are still running about 20-30kts
over northern lincoln county, so it looks like the main threat with
storms today will be strong winds and small hail.
Latest models indicate an increase in monsoonal moisture Saturday
across mohave, southern clark and eastern san bernardino counties
that is being aided by an easterly wave moving through northern
mexico. Pw values increase to over an inch stretching from southern
lincoln county through central san bernardino county with the 1.5
inch line pushing up the colorado river valley. This additional
moisture combined with increasing instability should lead to an
increase in thunderstorm activity for the southeast portions of the
cwa. Went ahead and expanded slight chance to chance pops to include
far southern clark and eastern san bernardino counties.
By Sunday, the easterly wave is forecast to be over northern baja
with the models indicating a couple of weak disturbances pushing
west through the far southern portions of the area. This could help
aid thunderstorm development over southern mohave and southeast san
bernardino counties with other areas such as clark and lincoln
counties relying on more daytime heating to get things going. Winds
up through 500mb are expected to be fairly light so flash flooding
would be a concern on both Saturday and Sunday. With the additional
moisture afternoon temperatures are expected to be held down a few
Long term Monday through Thursday.
An easterly wave will continue to pass by to our south on Monday.
This will allow monsoon moisture to spread across most of the area
leading to a chance of thunderstorms. It looks like the deepest
moisture and best instability will mainly be south east of interstate|
15. The wave is forecast to move west of baja by Tuesday afternoon
while high pressure develops across northern nevada. Moisture will
pretty much remain in place but the high pressure will likely keep
the atmosphere capped across the far northern part of the forecast
area but most of the area will still have at least a slight chance
of mainly afternoon and evening thunderstorms. The best chances will
be over the mountains of mohave, clark and san bernardino counties.
Drier air will work into the region today shifting the main threat
of thunderstorms to lincoln county this afternoon. Winds are
expected to remain fairly light through the day and temperatures
will be close to normal. Some additional moisture is forecast to
work into far southern mohave, southern clark, and eastern san
bernardino counties Saturday increasing the thunderstorm threat for
those areas. With the increasing monsoonal moisture any thunderstorm
will likely produce moderate to heavy rain. The threat of
thunderstorms will remain over the southern half of the area into
Creeks, streams and rivers in northern inyo county
have shown decreasing flows over the last couple of days.
However, some road closures continue in the area. Bishop creek
bypass and big pine creek bypass continue to be utilized to
minimize flows through bishop and big pine. Remember, never drive
through flooded roadways or around barricades. Also, pastureland
or farmland adjacent to creeks, streams or rivers could experience
areas of standing water.
Aviation For mccarran... Light winds this morning are expected to
become more easterly after 16z with speeds around 6-7 kts. Few to
occasional sct clouds around 12k feet, but no thunderstorms are
expected. Winds will then transition to a southwest direction after
For the rest of southern nevada, northwest arizona and southeast
california... Mostly diurnal wind pattern is expected at the
terminals into tonight. The main threat of thunderstorms will occur
over lincoln county this afternoon with generally dry conditions
elsewhere. Gusty outflow winds will be possible near any storms. Few-
sct clouds around 12k feet, but could lower to around 8k feet near
