Synopsis
Melting snow will continue to lead to minor flooding near creeks,
streams and rivers through the memorial day weekend and into most of
next week. Low pressure passing to the north will bring a period of
gusty winds on Wednesday with a few showers and thunderstorms
possible. The memorial day weekend looks warm and dry with a few
thunderstorms possible near the sierra crest on Monday.

Short term
Flows from snow melt remain elevated as melt water moves
downstream. Expect minor flooding to continue into the weekend
until cooler conditions prevail. For more information, read our
hydrology section below and check weather.Gov reno for warnings
and advisories.

A frontal boundary associated with a pacific northwest low
pressure system continues to be on track to push through the
region today. Expect winds to become gusty by this afternoon as
a result of the stronger pressure gradient across nevada; gusts
will be in the 30 to 40 mph range. Lake activities will become
hazardous in these conditions.

Thunderstorm chances for mono mineral have diminished somewhat as
shear has increased. Expect some "turkey towers" as updrafts form
but become cutoff from surface instability by breezy surface
conditions. The winds are right at the critical threshold for
thunderstorm formation, so left a slight chance in place. More
robust chances will occur along the lassen convergence zone and
extending eastward into pershing churchill counties as the frontal
boundary approaches; still only a slight chance of occurrence.

Otherwise, temperatures cool off from yesterday's high around 90
in western nevada through Friday with general troughiness across
the region. Highs will drop about 5 degrees each day with mid 80s
for western nevada and mid 70s for sierra valleys today. Boyd

Long term Saturday through Tuesday...

no changes to ongoing forecast. Upper ridge will be building across
the area this weekend and then shift slightly north and east early
next week as weak troughiness develops near the west coast. The
atmosphere will remain capped with limited moisture sat-sun. So we
should only see a few cumulus along the eastern sierra both days. As
southeast flow develops mon-tue, moisture will slowly move northward
into the sierra and instability will increase enough for a few
afternoon evening showers or thunderstorms. They will mostly be
limited to the immediate crest and south of lake tahoe Monday and
then spread a little farther north and east on Tuesday. Convection
could spread areawide Wednesday but a lot depends on strength and
track of upstream trough. Temperatures will be above normal with 70s
sierra and 80s to lower 90s in the lower valleys. Hohmann

Aviation
An upper trough will drop southward toward the region today with a
weak front sagging down into northeast ca and northwest nv. A few
showers and thunderstorms are possible along this front although
coverage is going to be quite low. Thunderstorms will also be
possible across mono-mineral counties late in the day with about a
5% chance of lightning within 10 miles of kmmh.

In between these two areas, including the tahoe basin-reno carson
city area and the highway 50 corridor to fallon, winds will increase
out of the west with a more stable atmosphere. Some lee turbulence
is possible as ridge gusts increase to 40-50 kts. Surface gusts will
generally be 25-30 kts at area terminals. Hohmann

Hydrology
The sierra snowpack will continue to melt over the next several
weeks. As we move into the peak of the melt season, impacts are
likely to become more prevalent for the eastern sierra, the
walker river system and upper portion of the carson river system.

Creeks and streams are running fast and very cold, bringing the
risk of hypothermia for those without protective gear. Those with
plans to camp in the sierra over the memorial day weekend should
be prepared to quickly leave creek side campsites. Hikers will
want to be cautious while trying to cross creeks and streams.

Also, be cautious if recreating near a river; some banks may have
become unstable from prolonged inundation and could suddenly
collapse. Brong boyd

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.
