Synopsis
Quiet weather anticipated through the end of august with dry
conditions and typical late day breezes. Near normal temperatures
today will increase to a few degrees above normal for the rest of
the week.

Short term
Minor changes were made to the forecast overnight as model
simulations for the passing trough midweek continue to deepen.

Main impact will be to keep temperatures from warming as fast,
with daytime highs just a few degrees above normal through
midweek. If simulations for the trough continue to deepen, chances
for showers near the oregon border may need to be added along with
breezier winds.

Otherwise expect mainly clear skies with light afternoon breezes
and near normal temperatures the next few days. -zach

Long term Thursday through Sunday...

the only substantive change made to the extended portion of the
forecast this morning was to lower high temperatures on Thursday.

Overall... The pattern evolution is very similar to past days. One
change is the strength of the longwave trough passing to our north
early Thursday. Some model simulations dig this trough a bit farther
south than previous forecast runs. Others are not quite as
aggressive. Most GEFS ensemble members suggest a lowering of heights
Thursday that justify dropping high temperatures. Most areas would
still have highs above normal. It would just be the difference
between previous guidance with highs 7-10 degrees above normal
versus the current guidance of highs only 2-3 degrees above normal.

We will not drop highs quite as much as the guidance suggests and
let the pattern evolve a bit more.

After Thursday flat ridging develops across the region and high
temperatures begin to rebound. Through the coming weekend we should
see highs in the mid to upper 90s for the lower valleys and 80s for
the sierra valleys; that is some 7-9 degrees above normal.

No precipitation is expected through the forecast period as moisture
remains cut off well to the south.

Beyond the forecast period... We are looking at the possibility of
the remnants of a possible tropical system lifting north toward the
southwestern u.S. By the middle of next week. The system has not
developed yet... But the hurricane forecasters are giving it a 90%
chance of formation. Remnant moisture lifting into the region could
mean a shift to more active weather prior to labor day weekend. We
will keep an eye on this potential as we move through the next week
and a half. Xx

Aviation
Vfr conditions are likely through the week and into next weekend as
a dry stable pattern develops. There is a very small chance that
stray thunderstorms could develop by Wednesday across northeast
california due to heating and a longwave trough passing to the north

But it is a very small chance.

Typical late afternoon early evening wind gusts in the 20-25 kt
range are possible most days. Wednesday could see the strongest
winds during the week then there is a possibility of increased winds
late in the weekend. Afternoon turbulence due to low level
instability is also possible each day. Xx

Rev watches warnings advisories
Nv... None.

Ca... None.

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.
