Synopsis
A cold front late Sunday and Sunday night will bring breezy conditions,
shower chances, and a cool down for Monday. A warmup will occur Tuesday
and Wednesday before another, much colder weather system brings
gusty winds late week along with much colder temperatures and
shower chances Friday through the weekend.

Short term
High pressure will build over northeast california, the sierra, and
western nevada through tonight before a fast-moving wave pushes a cold
front through the region late Sunday and Sunday night. As far as winds
Sunday afternoon and evening, they will pick up, but the timing
of the front is late in the day (near or after dark along the i-80
corridor), with 700 mb winds not maximizing until the evening
Sunday. The current expectation is for peak wind gusts mostly in
the 20-30 mph range, with wind-prone spots along the highway
395 i-580 corridor reaching up to 35 mph. With this in mind, will
not issue any lake wind advisories although there will be some
chop later in the day and into the evening.

With the Sunday night system taking a slider-like track into western
nevada, light rain (and snow above 9000 feet) showers are possible
down to around highway 50 overnight into Monday with a few showers
working south of highway 50 for the day Monday.

High pressure builds back overhead Monday night and Tuesday for drier
conditions with high temperatures rebounding 5-10 degrees between
Monday and Tuesday. -snyder

Long term Wednesday through Saturday...

with the area wedged in between a trough to the east and a ridge to
the west, Wednesday will be quiet weather-wise. Expect generally
clear skies, light winds, and near normal temperatures. This will
all begin to change on Thursday as a longwave trough moves in.

Like the last forecast cycle, changes were made in the Friday time
frame with some for Saturday, too.

Most of the day on Thursday will be similar to Wednesday. However,
ridge winds will begin to increase ahead of the trough, with breezy
afternoon valley winds. Clouds will increase through the day as the
trough drops south, with some slight pops moving into far northern
nevada and northeast california by late Thursday evening.

Widespread showers will move into the area overnight Thursday into
Friday morning. Coverage will increase through the day on Friday.

This is where most of the changes were made as pops were increased
area-wide. Winds were increased along the ridges, with Friday being
gusty even down to the valleys. There will also be a noticeable
temperature change Friday, with temperatures falling 10+ degrees
from Thursday afternoon. This will make for a chilly Saturday
morning. Light snow accumulations will be possible above 8,000'
Friday night.

Confidence is increasing for a deep trough to impact the west coast
next weekend into early next week. At the moment, there does not
seem to be a defined break in between the two systems. Thus, ridge
winds were kept elevated through Saturday but not as strong as
Friday. This may be adjusted over the coming days so check back
for updates. Either way, this looks to be another wet, cold system
to start the the fall season. -cassie
aviation...

light winds and clear skies this afternoon for all area terminals.

This will begin to change Sunday as southwest winds increase ahead
of an approaching trough. Expect gusts 20-25kts, with increasing
clouds. A chance of showers will increase through the day on Sunday,
lasting through Monday. After a brief break Tuesday-Wednesday, a
series of troughs will end the week. -cassie

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.
