What's New / NOTES
3/3/2018 - There is a new GOES Satellite for the east coast that required rewriting that part of the code. Please report any issues.
6/25/2017 - NOAA is having a major issue that impact the 7 day forecast load times. Many users are reporting problems. The issue has been reported.
5/23/2017 - Worked with NOAA again to speed up the 7 day forecast load times. Thanks to them for being responsive.

Synopsis
Warm afternoon temperatures are expected through Thursday, with a
cool down to near or possibly below average temperatures by next
weekend. Low pressure developing off the california coast will
bring increasing chances for showers and a few thunderstorms from
mid week into the weekend, with breezes increasing by Friday.

Short term
Little change to the forecast through Wednesday.

Tonight, surface high pressure over the pacific northwest will
build into northern nevada behind an upper disturbance skirting by
to the north. This will bring a switch to lighter north-east winds
for Monday, with some passing high clouds and possible late-day
cumulus near the sierra crest. Afternoon temperatures will ease
down (but remain above average) a few degrees for many valleys of
western nv, northeast ca, and mono county.

Tuesday and Wednesday, the threat for a few mid-afternoon to evening
thunderstorms returns. The threat is expected to be mainly for the
sierra, but a few cells could drift out into far western nv and
northeast ca on Wednesday as southerly flow aloft increases and
pushes cells off the sierra. In addition, to aid thunderstorm
development by Wednesday, simulations show increasing flow working
up the west slopes of the sierra as cooling in the sacramento
valley (increasing marine influence) increases thermal gradients
across the region. This could give convection a bit more convergence
to aid in the development of showers and thunderstorms. -snyder

Long term Thursday onward...

main weather feature of concern for Thursday into the weekend will
be the track of the closed upper low off the west coast. Day-to-day
variations in the simulations are making it rather tricky to pin
down where exactly it will end up. Simulations are settling around
the solution that it will impact the west coast somewhere between
northern ca and or around late week.

By Thursday-Friday, increasing moisture and instability in southerly
flow ahead of the low will bring chances for showers and thunderstorms
each afternoon and evening. Locations of particular concern will
be the sierra and adjacent lower valleys of western nevada, as
well as the sweetwater and pine nut mountains.

The timing between the ECMWF and GFS are similar, but the GFS is
exhibiting some elongation of the closed low as it approaches the
west coast for early Friday morning. By the weekend the ecmwf
still keeps the main core of the low off the coast and further
north into the pacific northwest, while the GFS quickly opens the
closed low and sends it quickly eastward across nevada. Although
forecaster confidence has increased a bit for showers thunderstorm
chances Thursday and Friday afternoons, the forecast after that
into the weekend remains fairly nebulous. Keep in mind, if the low
tracks north (ecmwf) temperatures may be mild with drier conditions,
while if it takes a direct track over the region (gfs) the weekend
could be much colder and wetter. -edan

Aviation
West to northwest breezes to 20-25 kts will decrease overnight,
with lighter winds andVFR conditions expected on Monday. The only
exception once again will be the martis valley ktrk where areas
of fog will be possible between 4 am (11z) and 8 am (15z) Monday.

Afternoon showers and thunderstorms are possible Tuesday through
Friday which could bring briefly lowered CIGS vis, mountain
obscuration, turbulence, and erratic winds. It's too early to tell
if a storm will directly impact a terminal at this time.

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.
