Synopsis
Thunderstorms remain a possibility each day through the middle of
next week. Storms this evening will again be mainly over the
sierra, potentially becoming more widespread this weekend into
early next week but predictability remains about average. Flash
flooding will become more of a threat late this weekend and into
early next week. Temperatures through the weekend will remain
above normal with weak afternoon breezes each afternoon.

Short term
Weak low pressure over southern california is bringing up modest
moisture to the region, especially over the sierra and western
nevada. Temperatures will be nearly 10 degrees above normal for
the next few days, helping to destabilize the atmosphere each
afternoon and evening along with the increased moisture. Isolated
to scattered thunderstorms are expected through this evening in
the sierra, then spreading more into western nevada especially
Saturday and Sunday.

Storms over the next couple days will have very little motion, as
the steering flow aloft remains weak. This means that storms will
be capable of producing a mix of localized heavy rainfall, as
well as potential for a few new dry lightning fires from
lightning outside the main storm cores. Inverted-v soundings will
mean high-based convection that will also be capable of producing
strong gusty and erratic outflow winds late in the afternoon and
evening after peak heating.

Storm coverage will increase a bit on Saturday and Sunday as the
weak low pressure retreats offshore and deepens, helping to
increase moisture from the southeast. Increased precipitable
water amounts over the next few days will also increase the flash
flooding potential each day. If you have outdoor plans through the
weekend, please monitor for thunderstorm potential in the
forecast and updates through the afternoon. Hoon

Long term Monday through next week...

with the eclipse coming on Monday, everyone is wondering about
cloud cover and viewing potential. At this time, the forecast
looks very complicated. First, we have low pressure off the
southern ca coast, partly cloudy skies are definitely a
possibility. Secondly, there is a possibility of leftover
thunderstorm debris clouds from Sunday night thunderstorms over
southern nevada that could push up into the area. And lastly, with
high clouds pushing in from a weak trough in the northern rockies,
this makes for very difficult cloud prediction for Monday morning.

There is a pretty good chance of partly cloudy skies, with at
least some eclipse viewing likely. We will continue to monitor the
conditions leading up to the eclipse.

With the low pressure remaining over southern ca, we will remain
in a favorable thunderstorm pattern through at least Tuesday.

Precipitable water continues to increase each day as modified
monsoonal moisture streams in. It's hard to say exactly how these
thunderstorms will evolve into next week, as the cut-off lows are
notorious for wobbling around and being very hard to predict the
details. We have kept in the chance of thunderstorms through
Tuesday and Wednesday.

Low pressure will get scooped up late in the week by the major
trough moving into the pacific northwest. Thunderstorm potential
begins to drop off for the last half of next week as drier more
stable air moves into the region. Hoon

Aviation
Isolated showers and thunderstorms are expected over the next few
days over the sierra and western nevada. Brief localized heavy
rainfall and gusty erratic outflow winds are possible with these
storms. Overall there is the highest chances will be at kmmh,
ktrk, and ktvl with 20% chance of storms this evening and Saturday
late afternoon. Lesser chances are expected for krno and kcxp,
although chances do increase late Saturday and Sunday for western
nevada. Thunderstorm chances continue through the weekend and into
next week.

Last thing, a wildfire east of kcxp could bring in smoke impacts
with MVFR conditions through tonight and into Saturday morning.

There is a slight chance we could also see for around ktrk in the
morning if we get rain around truckee. Hoon

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.
