What forecasters said that day

The local office's own words before this red flag warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

NWS Elko, NV wrote its last area forecast discussion before this red flag warning went out at Jul 21, 8:23 AM PDT, 3 hours 26 minutes earlier.

Area forecast discussion, Jul 21, 8:23 AM PDT, 3 hours 26 minutes before
Area Forecast Discussion
National Weather Service Elko NV
823 AM PDT Tue Jul 21 2020

.SYNOPSIS...Scattered showers and thunderstorms are expected
across NV for the next several days. Some stronger storms can form
both Tuesday and Wednesday leading to strong gusty outflow winds.
Tuesday and Wednesday will be critical fire weather days from the
dry lightning and the strong gusty outflows. Drier weather should
then gradually return to NV by the end of the week.

&&

.FIRE WEATHER UPDATE...Will be doing some freshening up of the
products and hazards for fire weather for the upcoming two days.
No changes in headlines will be made at this time.

&&

.PREV DISCUSSION... /ISSUED AT 205 AM /

SHORT TERM...Today through Wednesday. Scattered showers and
thunderstorms are expected this afternoon and evening. The
thunderstorms should get extra forcing from a MCV feature that
will translate across central NV. The forecasted atmospheric
profile is favorable that a few stronger storms can form today.
The storms will be a mix of dry and wet with the wet portion
expected mainly in the core of the storm. Strong gusty outflows
are possible with these storms as the atmosphere is sporting a
classic dry micro-burst characteristics. Wednesday will also be an
active weather day with further scattered showers and
thunderstorms. These will behave just like that of Tuesday with
similar threat. The biggest difference is that Wednesday is
looking to a greater chance for stronger storms. Both Tuesday and
Wednesday are critical fire weather days due to the low RH, strong
gusty outflows, and scattered thunderstorms. Ambient winds will
remain rather light and influenced by terrain today before gusty
outflow winds develop in the afternoon. Stronger south-southwest
winds are expected across central Nevada Wednesday as a drier air
mass begins to infiltrate into southern and central parts of the
state, essentially eroding convection from south to north.
Temperatures will continue to be hot with mid to upper 90s for
Tuesday. Wednesday should see some cooling due to the greater
cloud cover but highs will still be in the upper 80s to the low to
mid 90s.

LONG TERM...Thursday through next Monday.
Upper low circulation moves across Nevada on Thursday before
departing. Deeper monsoonal moisture stays east of Nevada through
the weekend, but some moisture and conditional instability lingers
across northern Elko County for a few storms and brief showers
each day through the weekend. Overall trend has the threat of
diurnal storms diminishing with each passing day. Weak trough
along the West Coast keeps the flow aloft WSW over Nevada, keeping
the monsoon east of the region. Temperatures stay steady but
remaining a little above average for late July, the warmest time
of the year.

AVIATION...Although VFR conditions are expected to hold at KWMC KBAM KEKO
KELY and KTPH, thunderstorms may affect all TAF sites this
afternoon and evening.

FIRE WEATHER...Red Flag conditions are expected in NV on Tuesday
and Wednesday. This is mainly from dry thunderstorms with
possible wet cores associated with a broad monsoonal push into the
region. Tuesday should see the bulk of the thunderstorms
concentrated in central NV south of I-80. Wednesday should see
more wide spread thunderstorms with the bulk of the activity in
northern NV. Both days are very favorable for the thunderstorms to
produce strong gusty outflows. The winds produced from the events
can reach and surpass 50 mph. In addition, stronger south to
southwest winds and lowering humidity across central Nevada
Wednesday will elevate fire weather conditions and potentially
affect new fire starts that could occur Tuesday across this part
of the state.

Thunderstorms activity will wane during the second half of the
week with isolated dry thunderstorms still being possible. The
amount of thunderstorms is not looking to be enough to warrant
critical fire weather conditions during this period.
