Synopsis Decreasing northerly breezes with gradually increasing
temperatures into mid-week for the region. Expect dry weather for
most with any shower and storm chances limited to northwest
arizona on Wednesday.

Discussion
Not much if any changes in ongoing forecast.

The focus for the next few days will be low closing off over the
lower colorado river valley. The pressure gradient (and associated
winds) along the river valley is expected to maintain or weaken
through tomorrow. Given the borderline nature of the winds today,
opted to leave the current lake wind advisory as-is, expiring this
evening. For Wednesday, as the low lingers in the lower colorado
river valley, moisture is wrapped around, bringing shower and
thunderstorm chances to northern mohave county before the low
begins to lift out of the region on Thursday.

As heights rebound, temperatures should as well through the end
the of the week. The only item of note that could force some
changes to the extended was disagreement between operational and
ensemble runs regarding how warm temperatures get at the end of
the week. Quite a few GEFS members are trending cooler and both
the operational runs of the GFS and ECMWF actually lie on outside
their respective ensembles on the hot side.

Fire weather Expect decreasing northerly winds and gradually
increasing temperatures over the next several days. Afternoon
humidities will fall near 5-15 percent for the deserts, 20-30
percent for the mountains; and recover to 25-30 percent for the
deserts and 50-60 percent for the mountains. No critical fire
weather is expected through the period.

Aviation For mccarran... North to northeast winds are expected to
gradually decrease through the afternoon early evening hours, then
transition to a northwest direction overnight. Occasional gusts 15-
20 kts possible. There is a chance that if speeds diminish enough
tonight they could take on a southwest direction. Very similar
conditions are expected Tuesday and Wednesday.

For the rest of southern nevada, northwest arizona and southeast
california... North winds of 5-12 kts continue to dominate across the
region today, with isolated areas along the colorado river valley
seeing gusts of 20-30 kts. Winds will taper off somewhat during the
overnight hours. Similar conditions are expected Tuesday and
Wednesday.&&

Spotter information statement Decreasing northerly breezes and
a warming trend are expected through the week. Spotter activation
will not be needed through the end of the week.

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 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.
