Area Forecast Discussion
National Weather Service Reno NV
152 PM PDT Sat Jun 6 2020

.SYNOPSIS...

Winds will continue into this evening with a few showers and
thunderstorms north of I-80. Lighter winds Sunday, but it will be
much colder with a few more showers and thunderstorms.
Temperatures near freezing are likely for many areas Monday
morning with warmer temperatures returning by midweek.

.DISCUSSION...

Winds have picked up as advertised, but peak gusts remain 30-35
mph for now with ridges gusting 60-70 mph. The strongest winds are
expected late this afternoon and early evening with gusts up to 50
mph along the I-80 and highway 50 corridors. There remain fire
concerns, see discussion below.

Showers are likely this evening also, mostly north of I-80 with a
few thunderstorms possible. The threat for any snow accumulations
or even snow showers for the Tahoe Basin and Sierra Front is lower
than previously thought. Most showers do not appear to make it
far enough south. Still, a few flurries down to 5000 feet remain
possible.

Sunday will be COLD. It will feel more like late winter than late
spring. Temperatures will be a good 25 degrees below average and
the brisk northwest wind will make it feel colder. The main change
to the forecast was to extend the threat of thunderstorms as far
south as I-80 in the afternoon/early evening. Convective allowing
models are all showing a threat for the showers and storms that
far south. Snow levels will rise to 6000-6500 feet during the day,
but will more likely be in the form of pellets.

Sunday night will be cold with drier air moving in and clear
skies. Many colder valleys will drop into the 20s with parts of
the Reno and Carson metro areas near or slightly below freezing.
Monday will be a nice spring day with light winds and temps about
10 degrees below average. Tuesday morning is not looking as cold
as it appears there will be enough mid and high clouds to minimize
radiational cooling. The chances of another frost or freeze are
less than 20 percent.

It looks rather benign mid week with temperatures rising back to
near or a little above average. Winds will be light, but a typical
afternoon zephyr is possible Wednesday and Thursday. Another
trough is looking likely Friday into Saturday, but the flavor of
it is in question. Will it be an open wave or a low cutting off on
the south end? There will be some increase in winds with cooling
temperatures along with the possibility of showers and
thunderstorms. X

.AVIATION...

Winds will continue this evening with peak gusts of 30-40 kts from
the SW at area terminals through 03Z. Winds will back off at the
terminals with gusts to 25 kts overnight. However, ridge winds
will remain strong, and may increase with LLWS from 00-09Z until
the front passes and winds become more uniform from the NW. Mtn
wave turbulence will also be present through the night.

Showers and a few thunderstorms will occur north of I-80, but
predominantly VFR conditions will continue. Only local areas of
MVFR in SHRASN through 12Z Sunday.

Sunday will see more NW winds with peak gusts to 25 kts and light
mtn wave turbulence but no LLWS. Showers and isolated
thunderstorms north of I-80 again from 19-02Z, but it will remain
VFR. Typical impacts with any TS with outflow winds to 30 kts and
some small hail. Then quiet from Sun night through Thursday with
light winds and VFR. X

.FIRE WEATHER...
Widespread strong wind gusts are affecting the Sierra and western
Nevada this afternoon. The strong winds are combining with dry
conditions (RH 12-25%) across west-central Nevada and producing
critical fire conditions. Red Flag Warnings remain in effect for
west-central Nevada through 8 PM tonight. Although winds will be
lighter for Sunday, it will still be quite breezy. Temperatures will
be dropping significantly overnight into Sunday morning, which will
help to alleviate the fire concerns due to winds on Sunday into
early next week. -Edan
