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 to near record temperatures today will cool down to below
average for the weekend. Thunderstorm potential increases for the
sierra, northeast california, and western nevada this afternoon
and evening. Breezy and mainly dry conditions are expected for
Friday, with a low to moderate chance for showers and a few
thunderstorms over the weekend as a low moves across the area.

Short term
The main changes to the short term forecast:
1) push the best chance for thunderstorms today to near and east
of highway 395 in western nv and mono county, and into northeast
california by the evening.

2) cut back on precipitation chances Friday.

A trough axis will swing to near the northern california coast by
Friday morning, bringing increasing divergence (broad-scale lift)
aloft later today and tonight. At the surface, the best
convergence along a thermal gradient is simulated to slide to just
east of the sierra by early evening, with the highest moisture
aloft (hint at shower thunderstorm placement) shown to kick out
into northeast ca and western nv in the GFS nam. The hrrr also
shows deeper convection developing over western nv rather than at
the crest. This makes sense conceptually given deep southern flow
aloft to kick any development off the sierra, as well as the high
elevation snow field which tends to limit development directly
over it. With all this in mind, the highest chance for showers
and thunderstorms today was shifted a bit north and east to near
and east of the highway 395 corridor... And off the crest entirely
by evening.

Tonight, the best chances for showers and even a nocturnal
thunderstorm or two shifts into northeast ca as the trough axis
swings around to the northern ca coast. Friday, a solid dry slot
is simulated to move over the region. This is expected to serve to
bring dry conditions to most areas. Also, as thermal gradients
between northern ca and eastern nv maximize with daytime heating
and the trough's cold pool, winds are expected to become gusty
late morning and for the afternoon Friday. Widespread winds of
15-25 mph with gusts 30-40 mph can be expected for much of the
region.

Saturday, the upper low moves into northeast ca and northern nv.

This is expected to bring the best chance for showers and a few
thunderstorms north of i-80, with lesser chances down to about
highway 50. Winds will kick up again with gusts 25-30 mph (locally
to 35 mph) for many areas between mid-afternoon and early
evening. -snyder

Long term Sunday onward...

after watching a myriad of forecast solutions the past week for the
closed low that will impact the region this weekend, there is
finally decent operational and ensemble model agreement. This even
now holds true for the latter part of the weekend into next week,
increasing forecaster confidence.

The closed low will be centered over oregon on Sunday with a final
shortwave digging down the western periphery into northern nevada
Sunday afternoon and evening. This will bring renewed chances for
showers Sunday with a few thunderstorms possible across northern
nevada near the oregon border. Showers look to linger into Monday
with a broad-scale trough and moisture present over the western
conus, but it looks to be too stable for thunderstorm development. A
final shortwave drops into the trough Tuesday, quickly dropping
south into the desert southwest. This could bring a few more
showers to the region on Tuesday, with thunderstorms possible
mainly south of highway 50 in the afternoon closer to the core of
the low.

It will feel quite cool this weekend into the early part of next
week, especially compared to the warmth as of late. High temperatures
will only be in the 50s and low 60s in valley locations with 30s
and 40s in the mountains. Snow or pellets could fall as low as
5500-6000 feet in the overnight and early morning hours with snow
levels around 6500-7500 feet during the day.

Ridging begins to build into the west for the middle into the end
of the week bringing a warming and drying trend. Temperatures
will likely return to above normal Wednesday, continuing to warm
into the end of the week. -dawn

Aviation
Showers and thunderstorms are expected this afternoon along the
western nevada sierra front which will track northward into the
evening hours into portions of northeast california. Storms bring
the risk of lightning along with gusty and erratic outflow winds,
and small hail up to 1 2" in diameter. Brief heavier rainfall may
also lower ceilings and visibility and obscure terrain. As is
typical with these type of storms, it is near impossible to predict
with much lead time if a storm will pass directly over an airport.

Probability would be about a 20 percent chance for any given
terminal.

Winds will increase area-wide on Friday with surface gusts of 25-30
kts possible and ridge gusts up to 70 kts. This will lead to
turbulence, but the southerly direction of the winds in the mid
levels will likely limit mountain wave development. Breezy conditions
linger into Saturday with winds turning more southwest to west.

Additional showers with slight chances for thunderstorms are
possible Friday and through the weekend, with a focus predominately
north of highway 50. -dawn
