Area Forecast Discussion
National Weather Service Reno NV
209 AM PDT Sun Jun 2 2024

.SYNOPSIS...

Above average temperatures will persist this afternoon with a
couple of weak weather systems enhancing afternoon winds and
allowing for precipitation chances early Monday across the
northern portions of the region. Confidence is high in a
significant warmup later this week as highs approach 100 degrees
in the hottest western NV valleys, with afternoon thunderstorms
also possible in the later half of next week.

.DISCUSSION...

* OVERVIEW: Just a few subtle changes to the forecast this
  morning. A few more light showers are possible across Lassen/N.
  Washoe/Pershing counties early Monday morning. A rather
  significant warm-up is in store this week, with lower NV valleys
  likely reaching into the upper 90`s. Otherwise, most of this
  week future it will remain sunny, hot, and dry. Stronger showers
  and thunderstorms will also be possible late this week.

* CHANCES FOR PRECIP: Another shortwave trough will be passing by
  on Monday, bringing another round of light showers to the
  northern portion of the CWA. Most of the rain will be kept north
  of I-80, although some showers many extend further south across
  western NV. These showers are still looking light and quick
  moving, with a low chance of lightning. Later this week we`ll
  see some afternoon thunderstorms return to the Sierra and
  western NV as early as Wednesday and lasting through the
  upcoming weekend. Still a lot of uncertainty in the showers as
  of right now, but as the main takeaway, prepare for an increased
  chance of thunderstorms late this week.

* TEMPS & WIND: There`s going to be an increase in temperatures
  later this week. Lower NV valleys may hit the 100 degree mark
  for the first time this year while Sierra valleys will get up to
  the mid-80`s. Current NBM probabilities have a 20-40% chance of
  western NV valleys hitting and/or exceeding 100 degrees from
  Wednesday through Friday. Even overnight lows will be relatively
  warm (mid 60`s) compared to the past couple weeks. So if you
  haven`t already, make sure you have working A/C and/or access to
  a cooling device. As for winds, it`ll be breezy through next
  week with just enhanced zephyr breezes on Monday.

Continue to exercise extreme caution if you are recreating near
fast and cold streams as hypothermia can quickly catch you off
guard if you are not prepared. Also, expect rivers to have higher
flows in the evening hours due to increased snowmelt during the
day followed by the lag time it takes for that water to flow down
down the mountain.

.AVIATION...

VFR conditions will prevail through today. Increased winds out of
the WSW on Monday, with gusts peaking around 25-30 kts between
20-06Z. Expect some brief light to moderate turbulence during
that time.

A few light showers will be possible starting late Sunday
night/early Monday morning, mainly for KRNO/KTRK/KSVE/KLOL. These
showers will last through Monday morning and finally taper off
mid-afternoon.
