Synopsis Cloud cover is expected to increase through tonight
and precipitation chances will begin to increase from west to
east this evening through overnight tonight. Unsettled weather
will continue through Thursday with valley showers and mountain
snow. Expect a brief break on Friday before another weather system
moves into the region by Saturday.

Update Scattered showers ahead of negatively
tilted trough over northwest san bernardino county and southern inyo
county will continue to develop and drift northward overnight. So
far, rain buckets across the southern sierra reporting less than a
tenth of an inch of rain over the past 3 hours.

Hrrr and href simulations quite similar tomorrow depicting a more
widespread band of precipitation across lincoln county, southwest
utah and northern mohave county tomorrow afternoon. A more broken
line develops across nye, clark and northeast san bernardino
counties late afternoon and evening.

Updated the pops based on the hi-res model output the rest of
tonight which keeps the highest pops across inyo county. No other

Discussion Today through Monday.

The latest satellite imagery shows scattered high clouds beginning
to fill in across the region with some cumulus developing mainly
near higher terrain this afternoon. These trends will continue
through this evening with cloud cover increasing as an approaching
negatively tilted trough continues to dig into our region. Moisture
is fairly limited with this system but isolated to scattered showers
will begin to increase later this evening across inyo county. As the
trough digs further into socal tomorrow, upper level difluence and
daytime heating will provide enough forcing and lift to initiate
showers and isolated thunderstorms across the mojave desert. The low
will eventually cut off overhead on Thursday before lifting off to
the northeast early Friday continuing precip. Chances through that
time. Decent instability will be in place on Thursday across the
region allowing for more scattered thunderstorm chances mainly
across southern nv and northwest az. With marginal moisture and dry
low levels, storm totals are not expected to be impactful. Snow
levels will start off around 7500-7000 feet and begin to drop
overnight Wednesday to around 5500 feet. Again, with marginal
moisture, 48+ hour snow totals are 7-10 inches above 7000 feet along
the eastern sierra, 4-6 inches in lee canyon and only 1-2 inches in
kyle canyon. Low amounts over a 48+ hour period should limit impacts
and no winter weather products are expected. Besides
precip. Thunderstorm chances, no other impacts are expected with the
mid-week weather system. Winds will be breezy from the south-
southeast through this evening across much of the region. Some
breezy to gusty southeast winds will be possible across areas
north and east of clark county tomorrow afternoon as the trough
digs into southern nv and pressure gradients increase across those
areas. Of course with any thunderstorm activity, winds may be
variable and gusty.

By Friday, a shortwave ridge will briefly be overhead in the
afternoon pushing any lingering moisture northeast. The break in
clouds and storm chances will be very brief though as another trough
is progged to dig into the great basin region overnight Friday
into Saturday. This next system will be fast moving and should
keep precip chances confined to south-central nv. Another ridge
will move overhead Sunday bringing mostly sunny skies through
Monday. &&

Aviation For mccarran... Light easterly winds are expected at the
terminal through the rest of the afternoon and evening before
turning back to the southeast overnight remaining below 10kts. An
increase in cloud cover is expected gradually throughout the day aoa
10kft. An incoming system tomorrow should further increase cloud
cover and shift winds to the south in the afternoon. Could become
gusty as well.

For the rest of southern nevada, northwest arizona and southeast
california... An incoming storm system over the next 24 hours will
first impact kbih with gusty south winds and an increase in cloud
cover and -shra by late this evening. Kdag will also see a response
in winds, initially being out of the southeast and shifting to
southwest late this afternoon. Minimal impacts expected at
kvgt khnd keed kifp.

These have not been checked for accuracy and in many cases have not even been read by anyone associated with I have no idea of they are useful or accurate, I leave that to the reader. 2) Articles others have written and submitted. If you have questions on these, please contact the author. 3) Articles that represent my personal opinions. These are intended to promote thought and for entertainment. These are not intended to be fact, they are my opinions. 4) Small programs that generate result presented on a web page. Like any computer program, these may and in some cases do have errors. Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. It is not checked for accuracy either by anyone at or by the source which is typically the US Government. See the NOAA web site for their disclaimer. Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
