Marine Weather and Tides
10/6/2018 Colors of tide XTide graphs changed to emphasize that they were upgraded. See next note. Comments welcome.
10/4/2018 I have fixed XTide and updated the harmonic files. There were some name changes so you might have to click EDIT to find the new station name.

Changes this evening include lowering temperatures a couple more
degrees in a few spots across western nv and decreasing pops for
Showers have ended for the most part across the eastern sierra
and the best chance for showers will be across northwest nv and
the basin and range overnight as the back side of the upper low
moves across northern nv. We lowered or eliminated pops south of
reno-tahoe. Clouds have broken quite a bit allowing for some spots
to drop into the upper 30s to around 40 already from reno-carson
city-minden. Fortunately, winds were keeping temperatures from
dropping too much more this evening. The main question continues
to be how much wind and cloud cover will persist overnight.
Satellite cloud trends and model sounding profiles suggest there
could be enough clearing from the carson city area southward to
the mason smith valleys for temperatures to drop closer to 30
degrees, especially late tonight when the gradients relax a bit
more and winds fall back. If you haven't covered sensitive plants
or brought animals sensitive to the cold inside already, you
should take steps to do so now rather than take the risk that
temperatures favor the low end of the possible range. Hohmann

a series of storms will keep high temperatures well below average
along with periods of breezy winds, rain, and mountain snow through
next week. Travel impacts from snow are expected in the sierra Monday
night through Tuesday morning. Cool showery weather will continue
through at least memorial day, but snow levels are forecast to be
above 7000-8000 feet after Tuesday.
ok, I know many of you don't want to hear this (and a few are
excited), we issued another winter weather advisory for the tahoe
area Monday night into Tuesday. I'm not going to promise, but
this should be the last snow advisory for the 2019 winter that
doesn't want to quit. No other major changes were made to the
The main forecast challenge today continues to be the threat for
sub-freezing temperatures to impact a few agricultural areas. Most
of our simulations have been forecasting breezy overnight winds
and substantial cloud cover that would inhibit temperatures
dropping below freezing. But, if clouds clear and winds die down
overnight this is still a possibility.
The overnight low temperatures for most of the agricultural areas
and in western nevada, and the reno metro area, is to bottom out
in the mid 30s. The one area that that has the biggest threat for
sub-freezing temperatures is from carson city, south into the
minden area, and out into smith mason valleys. We don't yet have
probabilistic temperature forecasts but I would put the chance for
freezing in any of those valleys around 30-40%.
Currently there are a few thunderstorms in west-central nevada
and numerous thunderstorms moving through the bay area and into
the california central valley. The storms in california could
bring some more light snow showers to the sierra crest, but this
should be minimal amounts and likely limited to the west slopes.
The next storm moves in tomorrow night with another 3 to 7 inches
of snow expected above 7000 feet with an inch or two possible down
around 6000 feet possible. We didn't issue an advisory for mono|
county because there is less snow expected in the eastern sierra
and the system is moving through mono county closer to Tuesday
morning. This should help prevent snow from sticking to passes
along the 395 corridor.
We did also issue a lake wind advisory for pyramid lake tomorrow
morning when northwest winds are expected to be gusting to around
30 mph and well aligned with the lake fetch. -zach
the biggest change was to add a slight chance of thunder for Friday,
Saturday, and Sunday.
The upper level low that drops through the area Tuesday will slowly
meander eastward. The position of the low will give just enough lift
for afternoon showers each day. A slight chance of thunder was added
on Friday, since the low will be sitting in a position that is known
to generate a few thunderstorms and less cloud cover will allow for
more daytime heating.
As the upper level low finally moves out of the area, another one
looks to drop down Saturday into Sunday. Expect widespread clouds
and showers to return. Snow levels will be higher than the storms
we've seen this past week, so accumulations should only occur at the
higher elevations, with few impacts. A slight chance of thunder was
also added Saturday and Sunday. Models are currently showing not-
insignificant instability for this area, particularly on Sunday.
This instability, combined with the lift generated by the low and
available moisture could generate a few thunderstorms. It's still
too early to pinpoint exact locations; however, it will be memorial
day weekend, so many will have outdoor plans. It's never too early
to start thinking about what precautions to take to prevent getting
caught in a thunderstorm.
There are still no signs of this pattern letting up, so it's likely
we'll stay cooler through the beginning of june... Cassie
a few showers will continue into this evening, but it will remain
vfr overall. Localized MVFR vis in -shsn in the sierra through 03z.
Winds will continue to gusts to 25 kts this evening from the west,
becoming more NW overnight, but diminishing for the terminals. One
exception will be kmmh and klol where winds will continue overnight.
More w-nw winds tomorrow, gusting to 25-30 kts after 23z Monday as
the next storm moves in. Mtn wave turbulence and local llws is also
anticipated, and it will continue into Tuesday. Widespread MVFR ifr
in the sierra after 08z Tuesday in -sn with occasional MVFR along
the 395 corridor for western nv in -ra. The worst conditions should
end around 18z.
Unsettled weather will continue through the memorial day weekend,
but the storms that do arrive do not appear to be as cold or as
strong at this time. What will change is a better opportunity for
thunderstorms as we head into next weekend. X
