Area Forecast Discussion
National Weather Service Reno NV
218 AM PDT Sun May 27 2018


Other than a few leftover rain showers in west central Nevada, dry
conditions with a warming trend are expected for the remainder of
the Memorial Day weekend. Even warmer temperatures are expected
Tuesday, then another weather system will bring some cooling with
increased winds and a chance for showers and thunderstorms later
in the week. The first weekend of June looks to be dry and warm.



The persistent upper low near the NV-Utah border isn`t expected to
move very much today. Most of eastern CA-western NV will see
drying with reduced cloud cover and about 10-15 degrees of
warming compared to Saturday. Areas in west central NV mainly
from US-95 eastward will see more clouds and possibly a few rain
showers today, as another weak wave wraps around the main low.

For Monday, the low finally moves into Utah while ridge axis
builds into northern CA/northwest NV, producing dry conditions
regionwide and a light north wind. This will lead to another 5-10
degrees of warming with highs reaching the lower 80s in lower
elevations and 70s near the Sierra.

By Tuesday, the ridge axis shifts to the east with increasing
southwest flow aloft over the Sierra. This will lead to further
warming with highs well into the 80s and possibly touching 90
degrees in western NV, along with an afternoon-evening zephyr
breeze. Afternoon cumulus buildups with this additional heating
could develop into a few late day showers and thunderstorms over
the favored convergence zones of northern Lassen County/far
western NV and Mineral-Mono counties. MJD

.LONG TERM...Wednesday onward...

The next trough moves into the west midweek bringing an increase in
winds Wednesday into Thursday, and a cool down to near normal for
the second half of the week. This trough differs from the lows
this month because it is an open wave (instead of a cut-off low)
and has a jet behind it, keeping the flow more progressive. This
means that while this feature will bring renewed chances for
showers and thunderstorms Wednesday and Thursday afternoons, it
won`t linger like storms of this past month.

Forecast models have been differing day-to-day on which day will
feature stronger winds, Wednesday or Thursday. Currently it appears
the 700 mb winds will be a bit stronger on Wednesday, but the
surface gradient will be stronger Thursday with continued mid-level
support. Thinking Wednesday may be gusty, while Thursday may feature
more sustained winds.

The first weekend of June looks to feature a general warming and
drying conditions. -Dawn



A few light showers remain possible through the central Nevada
Basin today mainly east of US-95, but otherwise the area should
largely remain dry. The potential for morning fog exists through
the Martis Valley, including KTRK the next several days due to
recent rains. North to northeast winds will generally be less than
15 kts, outside of north-south oriented valleys adjacent to the
White Mountains where gusts up to 30 kts are possible. -Dawn
