Synopsis Dry weather and high clouds are expected through mid
week before the next low pressure system approaches late Wednesday
and Thursday. Best chances for precipitation on Thursday are expected
across eastern inyo, esmeralda, central nye and lincoln counties.
Cool temperatures will gradually warm to near normal through the
middle of the upcoming week.
Short term Today through Tuesday night.
Northerly flow aloft will continue cold air advection over the
region this morning before a positive tilted ridge, with an axis
currently through eastern or and northern ca, builds eastward and
decreases flow aloft later today. With a moist upper tropospheric
profile, as viewed by present water vapor imagery, high clouds will
stream in from the north around the ridge apex this afternoon.
Northerly breezes are expected today, but should begin to taper off
through this evening, except in areas along the colorado river
valley. As surface high pressure increases over ut, gradients will
increase enough to keep breezy north winds in the river valley
through the short term. Elsewhere, light winds are expected Tuesday
and Wednesday. Mean ridging over our area will lead to dry
conditions. However, a weak impulse brushing the southeastern
portions area will give the east sierra crest a shot at a light
shower early Monday. Afternoon temperatures will be 4-7 degrees
below normal through with a cool air mass in place. Overnight
temperatures will hover near normal readings for late january;
coolest night is expected tonight into Monday morning.
Long term Wednesday through Sunday.
A fast moving broad pacific trough with limited moisture is
forecast to bring increasing southwest winds to the entire region
Thursday and the potential for some snow primarily to the southern
sierra and south central nevada through early Friday. Wednesday
will be relatively mild as the ridge pushes to the east ahead of
the approaching trough. A band of moisture in the base of the
trough will then move into the southern sierra Wednesday night
through Thursday morning. Additional moisture in the cold pool
will slide down over central nevada and nearby inyo county
Thursday. This trough will be a fairly cold system with h7 temps
of -10 to -12 degrees c sliding over central and southern nevada
Thursday night into Friday morning. Brisk northwest-north winds
will follow Friday then a strong area of high pressure will
develop over the weekend for a warming trend. Gusty north winds
will persist down the colorado river valley.
Aviation For mccarran... Gusty northwest-north winds around 20
knots will persist through early afternoon then speeds will
diminish and a typical light southwest wind will develop early
this evening. No significant clouds.
For the rest of southern nevada, northwest arizona and southeast
california... Northwest to north winds gusting 20-25 knots will
persist across southern nevada and northwest arizona through early
afternoon then winds will become light and variable this evening
and overnight. No significant clouds.
Spotter information statement No significant weather is
expected until Thursday through early Friday. 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.
