Synopsis Mostly dry and hot conditions are expected through
Monday, except for a few isolated showers in northwest arizona.
Breezy southwest winds will develop across the region by Monday
afternoon. A weak push of monsoon moisture is expected late
Monday into Tuesday. This will bring a slight increase in
shower storm chances through Tuesday for areas from las vegas
east. Breezy and drier conditions are expected through the
remainder of the week.
Short term Today through Tuesday.
Just a few very isolated showers storms have developed thus far
this afternoon. This is likely to continue through sunset before
quickly diminishing with the loss of daytime heating. Hot
conditions will continue into Monday. Increased southwest flow is
expected to result in breezy southwesterly winds across the region
by Monday afternoon. Gusts of 30-40 mph will be possible across
portions of southern nevada.
By Monday evening, a weak push of monsoon moisture will begin to
move into the area. A few evening overnight showers will be
possible with this push.
The best chances for shower thunderstorm activity will be on
Tuesday afternoon, generally from las vegas east. It currently
appears that a relatively sharp moisture boundary will be present
on Tuesday afternoon, which could act as a focus for initiation.
Storm motion will be to the northeast at 15-20kts which will
decrease the overall flood threat. The big question is will storms
be able to sustain development with the increased southwesterly
Long term Wednesday through Sunday.
The latest medium range models indicate that monsoonal moisture will
be primarily confined to northwest arizona from Wednesday on as a
south-southwest flow keeps moisture away from most of southern
nevada and southeast california during the middle to latter part of
the week. This is due to a persistent trough over the pacific|
northwest which will keep the mid level high over new mexico and
texas. The GFS is a little drier than the ECMWF and if it proves
closer to reality... There will not be sufficient moisture over
mohave county to support thunderstorms by the weekend. Temperatures
will be near or slightly above normal during the period.
Fire weather Just a few isolated showers and stray thunderstorms
are expected this afternoon over northwest az. Otherwise hot and
dry conditions are expected through Monday. Increased southwesterly
flow is expected across the region Monday into Tuesday, with the
strongest gusts of 30-40 mph across portions of southern nv. This
combine with dry air and drying fuels will result in near critical
fire weather conditions. A weak push of monsoon moisture will move
across the region late Monday through Tuesday, resulting in a slight
uptick in shower storm potential, mainly from las vegas east. Breezy
conditions and slow drying are likely for the latter part of the
Aviation For mccarran... Dry conditions with light winds
following close to typical diurnal trends are expected through
tonight. Speeds should remain around 10 knots or less for the
period. A few cumulus towers will be found over the mountains.
Gusty southwest winds are expected to develop Monday afternoon,
with speeds 15-20 knots and gusts up to 30 knots possible.
For the rest of southern nevada, northwest arizona and southeast
california... Light winds following diurnal trends are expected
through tonight. Gusty southerly winds will likely develop Monday
with speeds between 15-25 knots and gusts up to 35 knots possible.
The strongest wind speeds will be across nye, lincoln and the higher
elevations of clark county. Similar gusty southerly winds are
expected again on Tuesday.

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.
