Area Forecast Discussion...UPDATED
National Weather Service Reno NV
914 PM PDT TUE MAY 24 2016

.UPDATE...

No big changes made to the forecast this evening. Scattered
showers and a few thunderstorms continue this evening across
western NV and eastern CA. A few locations have had some good 24
hour rainfall totals from storms, including South Lake Tahoe and Bodie
Hills with around 0.75", as well as Incline Village with around
0.50" rainfall. Further south near Benton (close to Bishop, CA)
they also received about 0.76", which is significant for that
typically dry part of our forecast area. Most locations have seen
less than 0.20", however with small hail and gusty winds.

Showers will continue through the evening hours and then begin to
diminish overnight. More showers and thunderstorms are expected
for Wednesday and Thursday as well. Hoon

.SYNOPSIS...

Scattered showers and thunderstorms with below average temperatures
are expected through Wednesday as low pressure moves slowly south
across California. Snow may produce occasional travel impacts over
higher passes through midweek. Near average temperatures are then
expected through the Memorial Day weekend with decreasing chances
for showers and thunderstorms

.PREVIOUS DISCUSSION... /Issued 225 PM PDT TUE MAY 24 2016/

SHORT TERM...

An upper level trough is allowing for the development of scattered
showers and thunderstorms across the Sierra and western Nevada.
Coverage will remain scattered through the afternoon, but the more
favored areas in the evening will follow the forcing from the upper
level deformation area associated with the low. Expecting this to be
roughly south of Hwy 50 across western Nevada tonight with shower
coverage diminishing by Wednesday morning.

Wednesday will feature another potential for scattered shower and
isolated thunderstorm development with widespread destabilization
expected during daytime heating. Stronger cells could produce
accumulating small hail and heavy downpours, while higher Sierra
passes above 8500 feet may occasionally be affected by snow covered
or slushy roads.

Shower activity will diminish by Wednesday evening as the low begins
to depart the region. This will provide a drying and warming trend
into Friday with high temperature warming back to near season
averages. Highs will reaching into the low and mid 70s across
western Nevada with mid 60s for Sierra valleys. Overall, can`t rule
out a few isolated showers and thunderstorms into Friday mainly
across the Sierra but coverage will be much less in comparison to
today and tomorrow. Fuentes

LONG TERM...Memorial Day weekend into early June...

Low pressure over the Gulf of Alaska will drop into southern Oregon
and northern Nevada by Friday then linger over the Great Basin for
Memorial Day weekend. Chances for shower an a few thunderstorms
during the afternoons will occur each day through the holiday
weekend. Maximum temperatures will be in the 60s and 70s with
overnight lows in the 30s and 40s.

For those heading outdoors for some holiday weekend adventures, be
prepared for rain, high elevation snow and chilly nights. Breezy
west to northwest winds may also lead to choppy conditions on lakes
over the holiday weekend as well.

Simulations for early June are starting to show the potential for a
ridge to develop over the West, which may start to finally bring
some summer like conditions. -Edan

AVIATION...
Showers and thunderstorms remain possible into Wednesday with low
pressure over California and Nevada.

Showers and thunderstorms have already developed across much of
western Nevada. Main treats for this afternoon and evening will be
moderate/heavy rain, small hail and gusty outflow winds to 30-35 kts.

Another low may lead to additional showers and thunderstorms over
the Memorial Day weekend. Brong/Edan
