Synopsis Potent winter storm will begin to depart the region
tonight with improving conditions expected Friday and over the
weekend. Low temperatures the next few nights will be quite cool
especially in locations with significant snow cover. Moderating
temperatures are expected next week with dry conditions. &&

Short term Through Friday night.

Impressive winter storm continues this afternoon with snow
currently most concentrated between northeast san bernardino
county eastward into central mohave county, with scattered shower
activity elsewhere. Snowfall amounts up to 15 inches have been
reported near kingman, and a couple pockets of up to a foot in
parts of the morongo basin. Additionally, snow has been causing
problems on i-15 near mountain pass and halloran summit in the
past few hours, prompting a closure for the time being.

Anticipate gradually improving conditions this evening, but with
a cold pool aloft sitting over the region with 500mb temps of sub
-30c, at least some scattered snow shower activity is likely to
linger into the early morning hours. There may be some wrap
around shower activity developing from lincoln county into
northern clark county as the upper low sits near the ca az nv
triple point, perhaps allowing a few showers to drift into the
las vegas valley this evening, though I don't anticipate much
more than an inch accumulation if any.

Snow activity in the morongo basin should begin tapering off soon,
so I may cancel the winter storm warning early, but will hold off
until the remaining shower bands exit the area. Meanwhile, periods
of snow will continue into the evening across mohave county,
gradually shifting into southeast mohave county by morning. A few
additional inches may fall in kingman and along the i-40 us93
corridor before things taper off late.

Improving conditions are expected Friday but cold temperatures
will remain a concern. Given the thick fresh snowpack across most
of mohave county, a hard freeze is a good bet and a hard freeze
product may become necessary. Will hold off on issuing given we
have high impact winter weather headlines currently ongoing, but
will be something to consider tomorrow.

Long term Saturday through Thursday.

The mid level flow will turn much more zonal
Saturday, allowing for moderating temperatures, and an atmospheric
river slamming into northern california and oregon Sunday and Monday
will miss our area to the north. Left small pops in the sierra from
Sunday onward to account for the possibility of a little moisture
making it that far south, but the vast majority of our area should
remain dry. Temperatures will moderate quickly, with forecast highs
in las vegas reaching 50 on Saturday and the 60s on Tuesday.

Aviation For mccarran... Scattered shower activity will continue
to linger around the valley through late tonight. Showers during the
afternoon will be in the form of rain but as we go into the evening
hours and temps cool down, a transition back over to rain snow mix
and then completely to snow will occur after 00z. Winds will remain
light and variable through this evening before shifting southwest
after dark. Low ceilings, below 8k feet, will linger through tonight
before clearing occurs Friday afternoon. Behind this passing system,
the winds will shift to the northwest around 08z and will pick up to
10-15 knots gusting up to 35 knots early tomorrow morning through
the afternoon. Only a few lingering showers are possible Friday
morning.

For the rest of southern nevada, northwest arizona and southeast
california... A broad band of rain and snow is currently extending
across san bernardino, clark, and mohave counties. Most of this
activity is light but pockets of moderate-intensity precipitation
is possible. Low ceilings remain bkn-ovc below 5k feet for these
areas. This activity will become more scattered and shift
southeastward through tonight; lingering into Friday morning over
mohave county. Sky conditions will improve throughout the day with
gusty northwest winds expected. Speeds will generally stay
between 10-20 knots with gusts near 25 knots through late Friday
afternoon.

Spotter information statement Spotters are encouraged to
report snow amounts and impacts to roads according to standard
operating procedures. &&

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.
