What's New / NOTES
5/20/2018 -- NOAA is having problems with the data feed that I use to draw the graphs. They are aware of the issue and working to resolve it. Sometimes changing the location by about a mile will give a correct graph. 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.

Synopsis
Hot and dry weather continues with high temperatures around 10
degrees above average through Wednesday. Stronger afternoon
breezes returning on Monday and persisting through much of next
week. A cooling trend is expected with near average temperatures
for the end of the week.

Short term
Ridge of high pressure remains over the area today with light
winds and hot temperatures. There is a wildfire west of mammoth
lakes (west of devil's postpile) that is getting very active
today, producing quite a bit of smoke. This fire is being called
the lions fire. Smoke will continue to push into the eastern
sierra around mammoth lakes and lee vining through the day today
and into tonight. With the wind direction coming around from the
southwest the next few days, this smoke will likely be around for
days to come, with potential impacts to air quality in mono
county especially around mammoth lakes directly down wind of the
fire.

Temperatures will drop off nicely tonight and into Sunday morning
due to dry air over the region. By tomorrow, low pressure moves
into the pacific northwest that will help to increase temperatures
once again across our area. Monday will be the hottest day of the
week with highs in western nevada near 100 degrees and upper 80s
in the sierra and northeast ca.

As the temperature gradients increase Monday afternoon, we will
see a stronger than usual zephyr wind across northeast ca and
western nevada. This will be aided by the increasing winds aloft
from the low pressure passing through the pac nw. We will see
gusty winds Monday, with gusts up to 30-40 mph mainly north of
i-80 and east of us-395. These gusty winds and dry conditions will
lead to critical fire weather conditions over portions of our
forecast area. Please see the fire weather discussion below for
more details. Gusty winds will also make for choppy conditions on
area lakes as well, especially pyramid and in lassen plumas
counties.

Winds back off slightly on Tuesday, more along the lines of
typical breezy zephyr winds with gusts up to 25 mph in the late
afternoon hours. Temperatures remain around 10 degrees above
average as well. Another trough moves through the pac NW and
northern ca nv on Wednesday, potentially raising the winds once
again. -hoon

Long term Thursday through next Sunday...

a shortwave trough looks to impact the region on Thursday bringing
gusty afternoon winds and cooler temperatures around normal for this
time of year. Another round of fire weather conditions could be
possible Thursday afternoon due to the lack of atmospheric moisture
and gusty winds associated with the passing trough.

Cloud coverage increases by Friday afternoon with low pressure
towards the northeast. The question remains if this trough of low
pressure will dig farther south into eastern nevada or will it be
more progressive and move out of the region rather quickly. The ec
has been more consistent the pass couple of runs showing a faster
and shallower trough, while the GFS has it more amplified and
sticking around a little longer. Leaning towards the ec at this
point just because of the consistency and looks to be the more
common scenario given the time of year. Whichever outcome does
take place... Precipitation looks minimal in both scenarios.

By Saturday evening... Clouds begin to clear as high pressure tries
to build in from the southwest. Still looking active beyond Sunday
with the potential of another low pressure trough towards the north.

Aviation
Vfr conditions will remain for most of this week. There is a lot
of smoke near mammoth lakes this afternoon associated with a
wildfire west of mammoth mountain. This smoke could affect kmmh
later on this evening and tonight with lower visibility.

The main impact for other terminals will be gusty winds for
Monday tapering off by Tuesday morning due to a passing shortwave
trough. West- southwest winds in the 20-25 kt range with gusts of
up to 35 kts for most of western nv and the sierra.

By Tuesday... Breezy afternoon winds will remain, but will not be as
strong as Monday. -laguardia

Fire weather
Fire weather concerns are on the rise with fuels below 6000 feet now
showing signs that they have largely cured across western nevada and
extreme northeastern california. Hot and dry conditions continue
this week as a upper level trough passes north of the region. This
trough passage will result in enhanced zephyr winds on Monday
creating breezy to gusty winds along the sierra front into the basin
and range. Winds will gust 30 to 40 mph mainly north of highway 50
and east of highway 395. Also, afternoon humidity will range from
the single digits up to 15%. As such, red flag warnings have been
issued for fire weather zones 278, 450, 453, and 458(mainly from
gerlach southward) valid for Monday from 2pm through 10pm. While
winds are expected to drop due to thermal decoupling overnight,
grass fuel density would promote continued fire spread through the
overnight hours.

The trough will complete its passage over Monday night with poor to
moderate recoveries anticipated for western nevada and moderate to
good recoveries for sierra valleys and mid slopes Monday night.

Conditions on Tuesday remain hot and dry, but winds return to
typical zephyr speeds as another trough approaches for Wednesday.

Wednesday could be another critical day, due to enhanced winds with
breezes continuing into the end of the week. Temperatures do cool
somewhat by Thursday which would result in a slight increase in
humidity values during the afternoon with better overnight
recoveries. Boyd
