Synopsis
A ridge of high pressure will keep mild temperatures and light winds
over the region through Tuesday. Clouds begin to increase on Tuesday
as this ridge gives way to an approaching storm system. The best
chance for valley rain and mountain snow will occur Tuesday night
through Wednesday, with unsettled and showery conditions possible
into next weekend.

Short term
Forecast still looks mostly on track for the mid-week storm as low
pressure moves into ca nv bringing mountain snow and valley rains
to the region. The weather will be quite pleasant again for
tomorrow as high pressure remains over the region with above
normal temperatures. We will see an increase in winds and clouds
tomorrow as low pressure moves closer to the california coast.

As the storm moves in late Tuesday afternoon, we will see snow
beginning in the sierra with snow levels near 7500-8000ft and then
falling to near 6000 feet by Wednesday morning. Precip amounts
will be rather light to moderate with the main snow accumulations
right along the sierra crest from tahoe down into mono county.

Snow totals for the high sierra above 7000 feet Tuesday night
will be around 4-8 inches by noon Wednesday... Including the
mammoth lakes area. For elevations below 7000 feet, lesser snow
amounts of zero to four inches may be possible, with only an inch
or two around lake tahoe.

Snow accumulations during the daylight hours on Wednesday will be
minimal on road surfaces due to the march Sun angles. Snow
amounts will be below winter weather advisory criteria for the
tahoe basin and mono county, so we will not be issuing any winter
headlines for this event. We will continue update the special
weather statement for the minor impacts expected Tuesday night and
Wednesday night.

As the low pressure continues to move east across ca nv, the upper
level low will moves directly over our region. Underneath this
cold air aloft and with late march heating, we will destabilize
during the afternoon creating a situation for widespread rain snow
and snow pellet showers across the region and even a chance of
thunderstorms. Latest models continue to show good instability,
with lis around -2 and CAPE around 300-500j kg. Snow levels will
creep down to near 5000-5500 feet by Wednesday evening with a
deformation band setting up over west-central nevada on the back-
side of the low pressure. There is potential for another inch or
two of accumulations for the sierra above 6000ft Wednesday night
into Thursday morning, but not too much. Showers will continue
into Thursday morning, then clearing by the afternoon as low
pressure moves out of the region. -hoon

Long term Friday into next week...

a brief break in the rain and snow is expected during the day on
Friday before another glancing blow brings additional snow and
rain showers to the region Friday night. Recent model simulations
have split between a weak storm moving through the central sierra
and a more glancing blow with most of the precipitation north of
interstate 80.

Either way, this is likely to be a fairly weak storm with additional
snowfall likely measuring less then a foot at the upper elevations
and skiff to an inch or two possible down to 5000 to 6000 foot
range.

By early next week a large cutoff low pressure system is forecast to
develop off the northern california coast. This could bring another
decent round of rain and snow to the the sierra by the middle of
next week. However, being cut-off from the main jet stream flow also
means that predictability will be below normal. -zach

Aviation
Vfr flight conditions expected throughout the region today with
mainly light winds.

Precipitation could begin to impact the sierra as early as Tuesday
afternoon as a relatively weak trough moves through the region. Snow
levels are expected to be in the 6000 to 7000 foot range. Snow
accumulations of 2-4 inches are possible around kmmh with an inch or
two possible at ktvl. Increasing instability on Wednesday will
create the possibility of a few thunderstorms as well.

Another weak system could bring another round of rain an snow to the
region Friday night into Saturday morning. -zach

Rev watches warnings advisories
Nv... None.

Ca... None.

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.
