Synopsis A swift moving cold front will bring gusty northerly
winds to parts of the area tomorrow along with a slight cooldown
for the later portion of the week. A few additional disturbances
are possible this weekend and early next week... Mainly impacting
the sierra and southern great basin with shower chances.

Temperatures will be near to slightly above normal through the
period.

Evening update
Not too much change to the forecast during the evening update. Other
than typical hourly t TD fine-tuning, looked into latest model
trends for wind potential tomorrow. Wind advisory area looks good
for tomorrow, with best potential for advisory level winds being
north of clark county. Did note rapidly developing high pressure
across southeast utah tomorrow afternoon but the gradient drops off
near the northern mohave county border. Wouldn't rule out some
advisory level winds in extreme northern mohave county including
colorado city during the late afternoon early evening time frame but
this should be confined to the county border. The other
consideration is a lake wind advisory for tomorrow afternoon as the
gradient tightens across the colorado river valley. Looking at
gefs SREF plumes as well as ecm ecs mav met guidance and hi-res,
advisory level winds are not out of the question but the 90th
percentile is below the 25 mph sustained criteria. Thus, will pass
along these thoughts to the overnight shift for consideration but
will keep the npw as is for now.

Short term Through Thursday night.

Aside from some northerly breezes down the colorado river, fairly
tranquil conditions dominate the region today along with light
winds and clearing skies. A potent cold front will slide
southward tomorrow through the great basin and into the four
corners. The brunt of the energy with this system will be focused
to our north and east, but a burst of fairly gusty winds are
likely along and immediately behind the cold front tomorrow as it
passes through. High resolution models along with MOS guidance
suggest a 3-6 hour period of wind advisory level winds across
esmeralda, central nye, and lincoln county. Given the tendency of
model guidance to underplay north winds, as well as the sharp
thermal contrast advertised at 700mb along the cold front, went
ahead and posted a short wind advisory for the daytime hours
tomorrow.

Further south, gusty northerly winds will invade the mojave desert
region and slide down the colorado river valley during the late
afternoon and evening. Winds especially near laughlin and bullhead
city may briefly bump up to wind advisory levels but overall
duration and spatial coverage should limit the need for any wind
headlines. These northerly breezes will linger down the river into
Thursday, but look to hover just shy of lake wind advisory
thresholds.

Boosted temperatures upward a couple degrees along and south of
the i-15 corridor where afternoon temps may get a little boost
from the enhanced mixing brought by the incoming winds and cold
frontal passage. Cooler temperatures likely Thursday, but
still topping out around seasonal normals.

Long term Friday through Tuesday.

Models differ with the speed of a shortwave trough passing
through Friday night or Saturday, but mostly agree on a low
amplitude wave with few sensible weather effects on our area. The
next storm is forecast to slam into the west coast on Sunday, and
the models disagree on how it will evolve. Some ensemble
perturbations show the trough splitting as it reaches the coast,
with our area being affected by the weaker southern piece similar
to what is happening this morning, while other members keep the
trough in one piece until it is well inland. Neither of these
solutions would favor significant precip for our area, so backed
off pops somewhat. Generally light winds through the period and
temperatures near to above normal.

Aviation For mccarran... Light and diurnal winds expected to
continue through the overnight hours tonight. Tomorrow by 20z,
northerly winds up to 12 kts expected along with a few gusts and
will persist through the evening. Few clouds AOA 15 kft through
the forecast period.

For the rest of southern nevada, northwest arizona and southeast
california... Light and mostly diurnal winds expected, though eed and
ifp will see north breezes until sunset, after which they become
light and variable. Few clouds AOA 15 kft through the forecast
period expected.

Spotter information statement Spotters are encouraged to report
any significant weather or impacts according to standard operating
procedures.

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.
