Synopsis
Cool, showery weather, with periods of steadier precipitation, and
a chance of thunder, will continue into the memorial day weekend.

Increasing snow levels will keep impacts from snowfall above 7500
to 8000 feet. Warmer temperatures with less overall precipitation
is expected by the middle to end of next week.

Short term
Low pressure currently moving into northwestern arizona will keep
showers and thunderstorms in the forecast today. Shower activity
slowly subsided overnight in most of western nevada. However,
additional showers are moving into region from the east as a jet
streak moves the area this morning.

Showers are expected to increase through the morning, mainly
south of i-80, as this jet feature strengthens overhead. By early
afternoon we could see a few weak thunderstorms form in western
nevada and into the sierra, again mainly south of i-80, as daytime
heating adds additional instability to the mix.

By Friday, another low pressure will be moving into oregon
bringing additional chances of rain and thunderstorms into the
region. Storms on Friday are expected to form over the sierra in
early afternoon and move into western nevada during the day.

Clearing skies in the morning could allow a few more robust cells
to form, if the deserts get a chance to warm up a little better.

Additional shower activity will also be possible into the late
evening and overnight hours as a cold front slides into the region
from the north.

Additional showers and thunderstorms are expected Saturday as a
stronger low pressure dropping down the coast into northern
california brings additional forcing to the region. -zach

Long term Sunday through Wednesday...

longwave trough will remain over the western states through the
weekend and into early next week as additional shortwave energy
drops down along the pacific coast, reinforcing the trough. This low
pressure over ca-nv will keep cooler temperatures, widespread
showers, and a slight chance of thunder during the afternoon and
evening hours. As the mid-level shortwave slides down along the
northern ca coast on Sunday, this will provide a favorable area of
moderate showers over the sierra and western nevada. Low pressure
will start to move out of the area on memorial day, although a few
showers will remain in the forecast.

Overall, Sunday looks to be the wettest day, with most likely
rainfall around 0.50" in locations from reno-carson city-tahoe down
into mono and mineral counties. Storm total rainfall amounts could
total up to over 1.0" for the three day weekend. Anyone with outdoor
plans this holiday weekend should have a "plan b" for indoor
activities due to likely wet weather. There will be some not-so-
happy campers this weekend. Snow levels will be around 7500-8500ft,
so only the highest sierra passes will be affected by snow,
including carson pass and mount rose summit.

Weak ridging moves over the region Tuesday and Wednesday with
diminishing chances for showers and increasing chance for scattered
sunshine. -hoon

Aviation
MVFR ifr CIGS remain through the morning with light showers. We will
see some limited clearing during the mid day today with increasing
chances of showers and thunderstorms again this afternoon and
evening... 40% chance around ktrk krno kcxp, 50% for ktvl and 70% chc
for kmmh.

Another low pressure will move over the region during the memorial
day weekend with showers and thunderstorms, MVFR CIGS and mountain
obscuration. -hoon

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.
