Area forecast discussion, Jul 29, 3:22 AM PDT, 9 hours 24 minutes before
Area Forecast Discussion
National Weather Service Elko NV
322 AM PDT Thu Jul 29 2021

.SYNOPSIS...Afternoon and evening thunderstorms are expected
through the rest of the week with at or just above normal
temperatures. A wet weekend is in store with below normal
temperatures.

&&

.SHORT TERM...Today through Friday afternoon

Monsoon moisture continues to stream into Nevada. Afternoon and
evening thunderstorms will develop again today, with best
coverage south of I80 and isolated coverage north of it. Fairly
slow flow today will allow for some spots that do get showers to
have higher rainfall totals once again and a storm or two could
produce localized flooding. There may also be a few strong storms.
High temperatures will be in the 80's in central Nevada and the
mid 80's to mid 90's in northern Nevada valleys.

Some shower and isolated thunderstorm activity will likely
continue overnight tonight, mainly in eastern Nevada, with
overnight lows in the mid 50's to the mid 60's.

Pwats jump on Friday, as the ridge axis that has been over central
Nevada quickly shifts westward over the western US. This will
allow for a much greater surge of moisture to funnel northward
into Nevada. Shower and thunderstorm coverage is expected to
expand through the day and precipitation will become fairly
widespread by evening. The WPC has a slight risk for excessive
rainfall well into central Nevada, which does not occur often. The
SPS for excessive rainfall was expanded to the Friday through
Sunday period and a Flood Watch could very well be issued later
today for at least central Nevada. Some strong storms are also a
possibility. Dropped highs down some as cloud cover and showers
will likely limit afternoon heating.

.LONG TERM...Friday night through next Wednesday
Deep monsoonal surge continues through the weekend as high
pressure centered over the central Plains is favorable. Embedded
short wave energy will be moving northward. Potential significant
rainfall and flash flooding will be dictated by mesoscale
features, which is a challenge 2-3 days in advance but expect a
day of heavy rainers for Saturday, possibly some cells persisting
through the night. Another possible outcome is a beneficial
stratiform rain as the moist environment stabilizes. Precipitable
water content will be anomalously high. Once the wave shifts north
of Nevada, drier air does spill into northwest Nevada, but
eastern part of the state remains moist with localized heavy
rainers.

Monday through Wednesday a Pacific trough will be along the West
Coast with drier southwest flow advecting drier air into the
state. There is a chance that energy ejecting from the trough
brings a little cooler air, but not fully confident that this
occurs. Some instability may persist over the northeast NV corner,
but the overall trend will be for diminished diurnally driven
convection as the monsoonal moisture gets pushed east. With more
sunshine, afternoon temperatures return to the 90s.

&&

.AVIATION...More showers and thunderstorms expected this
afternoon and evening for a majority of the sites. For KELY, the
strongest of today's activity is expected here in the afternoon
before spreading north to KEKO and KBAM closer to the evening
hours. Look for KEKO to have better chances of thunderstorms at
their site. To the south KTPH will see storms start to the north
in the early afternoon before seeing more isolated thunderstorms
around the area in the evening hours. KWMC is not expected to see
much activity, but distant thunderstorms from the east are
expected to be present in the evening alongside decent high cloud
cover. Smoke and haze will continue to be present in the northern
sites, but expect it to have a minimal impact to conditions for
today.

&&

.FIRE WEATHER...Another round of showers and thunderstorms can be
expected today. Main threats will be locally moderate to heavy
rain and gusty and erratic winds.

Friday through Sunday. A very moist airmass will move into the
area. This will expand areal coverage to many locations with a
higher chance of wetting rains being seen in the area. The fly in
the ointment is the amount of cloud cover and destabilization of
the atmosphere. If cloud cover remains high, there is less of a
potential for the forecast precipitation amounts. Suffice to say,
the wet storms will limit the risk of new starts.

.LKN WATCHES/WARNINGS/ADVISORIES...
