Synopsis A potent low pressure system will affect the entire
region generating scattered showers and isolated thunderstorms
before it slowly lifts away late Thursday. High temperatures will be
around 25 degrees below normal on Wednesday. Expect warmer
conditions Friday and Saturday before the next system embedded in
this active weather pattern brings more cool and unsettled weather
conditions to the area late in the weekend into early next week.

Discussion Through next Tuesday.

Showery weather and even cooler temperatures will be on the way
tonight and Wednesday as a broad closed low across northern nevada
and california slides down over southern california nevada. A belt
of strong winds with gusts over 40 mph across the desert areas south
of las vegas will gradually decrease this evening. The frontal
boundary along the base of the system could be seen on satellite
loops sweeping down toward southern nevada this afternoon and this
will push into the las vegas area early this evening then stall out
with isolated to scattered showers. The western half of the system
will then pivot down over california tonight and circulate directly
over our forecast area Wednesday through Wednesday night then slowly
lift up over utah on Thursday. Sufficient moisture, cold air
instability and dynamic forcing with the circulation will generate
scattered showers over most zones. Snow levels will be down around
5500-6000 feet Wednesday morning then will lift to about 7000 feet
in the afternoon.

A mean trough is forecast to remain over the region Friday and
Saturday which will keep chances for showers over the area from
southern sierra to central nevada. Temperatures will rebound
somewhat, but readings will still hold several degrees below normal.

Additional energy diving down the west coast will spin up into a
closed low and swing into the region Sunday and Monday. Confidence
is low in precipitation details, but it will keep the weather
unsettled late in the memorial day weekend.

Aviation For mccarran... Gusty southwest winds expected through
the remainder of the afternoon before shifting to the northwest
behind a weak cold front. This front is expected to push through the
las vegas valley between 00z-02z this evening with winds shifting to
the northwest. Wind speeds are expected to decrease somewhat with
speeds generally between 10-15 kts. Winds will gradually become
light and variable overnight and early Wednesday morning. East to
southeast winds are expected by late morning and afternoon with
speeds 10 kts or less. This approaching cold front will bring an
increase in clouds along with shower chances after 03z this evening
which are expected to continue through much of Wednesday. CIGS down
to 8k feet at times.

For the rest of southern nevada, northwest arizona and southeast
california... Strong southwest to west winds will continue into this
evening across san bernardino county where winds over 50 kts are
likely. These winds will gradually diminish after 06z, but still
remain 20-30 kts overnight and into Wednesday. Gusty southwest to
west winds elsewhere with speeds 20-30 kts expected to shift to the
northwest behind a cold front that will push through the region
early this evening with wind speeds 15-25 kts. However, winds are
expected to diminish overnight with most areas seeing winds under 15
kts. Chances for showers, along with low ceilings and terrain
obscuration, will spread south across the southern great basin this
afternoon into Wednesday.

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

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.
