The local office's own words before the first event, 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 the first event at Aug 11, 1:05 PM PST, 3 hours 55 minutes earlier.
Area Forecast Discussion National Weather Service Elko NV 205 PM PDT Tue Aug 11 2020 .SYNOPSIS...Mixed thunderstorms are occurring today across much of northern an into central NV. On Wednesday, isolated thunderstorms will be confined to Elko County and there will also be some gusty winds in northwest Nevada. Thursday onward will see mainly dry and hot conditions across the whole of the silver state. && .SHORT TERM...Today through Thursday. Thunderstorms and virga continue across central and northern NV today and should last into the evening. The thunderstorms are a mix of a wet and dry but even wet storms wont cause too much accumulating precipitation. The thunderstorm coverage will be isolated to scattered which is causing critical fire weather conditions. All the storms however are still capable of producing strong gusty outflows that can propagate far from the parent storm. Wednesday will see a trough pass mainly to the north of NV clipping primarily the northern portion of the silver state. As this occurs a four corners high will build into the region from the southeast. This will shift the moisture to the northeastern portion of NV with dry air moving across the rest of the silver state. The shift between the trough and ridge will cause strong gusty winds mainly in northwestern NV. These winds coupled with low RH will cause critical fire weather conditions. Thursday will see the four corners high fully engulf the silver state with dry air. This will lead to many days of fair, dry, and hot weather. Temperatures will be hot for the next few days with highs in the 90s. Thursday will be the starting point for the gradual warming trend that will see NV eventually go into the upper 90s and lows 100s. .LONG TERM...Thursday night through Monday. Upper level ridging will remain in place across the Arizona/New Mexico border. Skies are expected through the night. Lows will be in the 50s. The upper level ridge will be moving to the west, and will be centered over central Arizona for Friday. This will maintain the mainly sunny skies and quiet weather over the region. Highs on Friday will be upper 80s to mid 90s with light winds. Quiet conditions remain during the overnight with lows in the 50s. By Saturday, model solutions show the ridge strengthening over Arizona with moisture trapped beneath the ridge. Right now have kept isolated dry thunderstorms in the forecast for mainly the central part of the forecast area, US Highway 50 corridor. High temperatures will rise a few degrees to the low to upper 90s. Winds will be light, though some virga showers could produce outflows. It will be a warm night with lows in the 50s and 60s. On Sunday and Monday the ridge will continue to build and as moisture becomes trapped under the ridge, this will lead to an expansion in dry thunderstorms for northern and central Nevada for both afternoons. Will need to watch this for possible fire weather headlines, but for now, confidence is too low. Highs on Sunday and Monday will be above normal with readings in the 90s to near 100 degrees. Took a look at the HeatRisk and for now, no heat headlines are anticipated. Overnight lows will be in the 50s and 60s. && .AVIATION...Conditions are expected to remain mostly VFR through the overnight. Isolated to scattered -TSRA will be possible though the early evening hours. Have input TEMPO for KEKO and KWMC terminals. Look for clearing skies after 08Z tonight, followed by quieter weather conditions tomorrow. Winds will be breezy Wednesday afternoon with SW-S winds 15-20KTG30-35KT possible, especially across the northern sites of KWMC-KBAM-KEKO. && .FIRE WEATHER...A mix of thunderstorms is occurring in all fire zones excluding 476 this afternoon and evening. The majority of thunderstorms will be in zones 437, 438, 469, 470, and 424 with a lesser amount in 425 and 427. A Red Flag Warning for thunderstorms remain in effect to 8 pm PST for thunderstorms in fire zones 437, 438, 469, and 470. The thunderstorms or any virga showers will be capable of producing strong gusty outflow winds that can propagate a long distance from the parent storm. On Wednesday isolated thunderstorms should be confined to FW Zones 469 and 470. An increase in southwest winds is also expected in northern Nevada due to a passing system to the north. FW Zone 424, 437, 438 will reach critical conditions with gusty winds a low RH thus a Red Flag Warning has been issued. Northern portions of FW Zones 438, 469, and 470 will also have elevated winds, though may remain just below Red Flag conditions, especially with slightly higher RH expected in those zones. && .LKN WATCHES/WARNINGS/ADVISORIES... Red Flag Warning until 8 PM PDT this evening for Central Elko County-Eastern Elko County-Humboldt County-Quinn-Southeastern Humboldt County and northern Lander County-W Elko County, N Eureka and Lander Counties N of I80. Red Flag Warning from noon to 9 PM PDT Wednesday for Humboldt County-Quinn-Southeastern Humboldt County and northern Lander County-W Elko County, N Eureka and Lander Counties N of I80. && 99/86/86/99
