Synopsis Cool and windy conditions can be expected through
today across most of the area. Winds will decrease a bit Sunday with
improving conditions and significant warming temperatures for the
week ahead.

Update Main concern this morning is whether the winds will pick
up down the colorado river valley. Morning sounding shows stronger
winds aloft, and rising temperatures should bring these winds down
to the surface as the atmosphere couples. However, if gusts have not
materialized by noon, may cancel the wind advisory and red flag
warning early. Will continue to monitor.

Short term Today through Monday night...

upper low currently near the 4-corners region will continue to push
south and east during the day. There will continue to be enough of a
surface pressure to bring gusty north winds to mainly the eastern
2/3s of the forecast area. Most areas will see gusts upwards of 30-
35 mph, but winds will remain stronger down the colorado river
valley where winds will continue to gust to over 40 mph. Those winds
are expected to peak by late morning and early afternoon before
diminishing by late afternoon. The current wind advisory looks good
and no changes needed.

The area will remain under a dry northwest flow Sunday, but with
less influence from the upper low winds will be much lighter. Will
likely see a few gusts in the 15-25 mph range down the colorado
river valley in the morning, but winds will diminish in the
afternoon and are not expected to be strong enough for any
advisories.

High pressure will start to nudge into the region from off the
pacific bringing lighter winds along with rather warm temperatures.

Temperatures will increase about 5 degrees today over yesterday and
then jump an additional 5 degrees on Sunday and again Monday putting
the area about 5 to 8 degrees above normal.

Long term Tuesday through Friday.

There is good model agreement Tuesday-Thursday, then significant
model differences develop Friday-next weekend in the evolution of a
deep trough somewhere near california/nevada.

Ridge over the eastern pacific on Tuesday will shift inland over the
great basin Thursday. A warming trend is in store with readings
warming to their warmest readings this year. Could see the first
triple digit readings in the eastern part of las vegas on Thursday.

On Friday, GFS keeps ridge intact with additional warming possible.

However, the ecmwf/canadian start digging energy down the west coast
which will eventually evolves into an unseasonably deep upper low
over california/nevada next weekend. Several GFS ensemble members
are supporting a deep trough but placement looks to be further west
of california. Left the forecast dry for now, but if the deeper
solution pans out look for more unsettled conditions next weekend
with cooler temperatures, gusty winds and chances for some showers
and thunderstorms.

Fire weather Cool and dry, along with windy conditions are
expected across much of the forecast area today. The strongest winds
will remain down the colorado river valley where a red flag warning
remains in place due to gusty winds and low relative humidity.

Lighter winds are expected Sunday. Dry conditions along with a
warming trend is on tap for the upcoming week.

Aviation For mccarran... Gusty winds are expected again today with
gusts into the 25-30 kt range. Winds this morning will likely remain
out of the north, but will turn more northeast during the afternoon
and early evening. Winds will also diminish by late afternoon and
evening with winds speeds generally around 10-15 kts. Just a few
high clouds expected.

For the rest of southern nevada... Northwest arizona... And southeast
california... Gust northerly wind will continue at all terminals
through today. Winds speeds generally between 15-25 kts with gusts
over 30 kts at times. Strongest winds will remain down the colorado
river valley where winds gusting to around 40 kts are expected.

Winds will diminish across the region overnight with lighter winds
expected Sunday. No operationally significant clouds are expected.

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

It is not checked for accuracy either by anyone at L-36.com 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.
