Synopsis
Temperatures will begin to warm today through Sunday before another
cold front brings gusty winds, shower chances, and a slight cool
down into Monday. A warmup will occur Tuesday-Thursday before
another cooler weather system moves into the region late next
week.

Short term
The main change to the inherited forecast was to slightly slow down
the forward progression of the cold front Sunday into Monday.

Freezing fog was also added for the sierra valleys north of lake
tahoe. The big weather story is the variable weather expected in
the next 7-10 days.

Temperatures: after some chilly weather this morning, we will begin
to warm up going into the weekend. Expect mid to upper 70s in
western nv and mid-60s to low 70s for sierra valleys Saturday and
Sunday. A slight cool down will occur Monday as a weak cold front
passes across our area. Highs will then warm to nearly 4-7 degrees
above normal by Wednesday. This translates to low 80s in western nv
and 70s for sierra valleys on Tuesday.

Winds: light winds are expected this evening through Saturday,
before the pressure gradient tightens ahead of an approaching cold
front Sunday. Winds are forecast to gust as high as 30 mph for most
areas Sunday afternoon ahead along cold front. Localized travel and
recreation impacts are possible with this system. Winds Monday
behind the front will be breezy out of the north northwest, however
minimal impacts are expected.

Precipitation: dry conditions will prevail Saturday and most of
Sunday. Showers are possible Sunday afternoon into Monday. Best
chances will be north of interstate 80 to the oregon border. Some
higher mountain snow showers are possible, but confidence is low.

Long term Tuesday through next weekend...

well, if you've liked the roller coaster of fall weather the last
few weeks, you're going to like the long term forecast. If you
prefer warmer and drier weather only, mid week is right up your
alley... And you may want to stop reading at the end of the next
paragraph.

Warmer and drier conditions are expected for the the middle of next
week as high pressure builds over the eastern pacific. Temperatures
are expected to rebound to the low to mid 80s in the valleys and mid
70s in the sierra, about 5 degrees above average.

For the long range forecast, ensemble models are good agreement that
another trough will move into the region during the second half of
next week, likely lasting into the weekend. This will bring
increasing chances for additional precipitation along with much
colder temperatures back to the region. By next weekend, daytime
high temperatures could be back down to 10-15+ degrees below normal.

Aviation
Mostly clear skies expected for tonight with areas of freezing fog
in the sierra valleys, including trk with lifr conditions.

Otherwise,VFR conditions continue through the weekend. Winds will
increase on Sunday afternoon ahead of another cold front moving
through the region. These increasing winds will bring some mountain
wave turbulence and wind gusts at the terminals up to 25-30kts.

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.
