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 Sep 7, 1:29 PM PST, 6 hours 31 minutes earlier.
Area Forecast Discussion National Weather Service Elko NV 229 PM PDT Mon Sep 7 2020 .SYNOPSIS...Smoke and haze continues to clear out of the area today as winds shift to a northerly direction. A cold front tonight brings colder temperatures, and the possibility of a few snowflakes to the highest elevations in northern Elko county. Tuesday will be drastically cooler with highs in the upper 50s and 60s, but this is short lived as temperatures rebound and hit the 80s and low 90s by next week. && .SHORT TERM...Today through Wednesday. The high pressure that has long oppressed NV with unbearably hot temperatures is finally being supplanted by a deep low pressure system. The low pressure is in the process of moving a cold front through the Silver state which will bring strong gusty winds and colder temperatures. The winds will be strongest this afternoon to evening with the winds being highest wind speeds in northeast NV with a Wind Advisory in effect for northern NV. The winds will weaken during the overnight hours but will still be gusty with borderline advisory level winds still possible Tuesday morning. The winds will finally begin to subside Tuesday afternoon to evening. A side benefit to the gusty winds is that it will scour out the smoke and haze in the region bringing better air quality. The gusty winds coupled with dry air will create critical fire weather conditions everywhere today and in central NV on Tuesday. Colder air behind the front will see NV plummet an average of 30 degrees. This colder air will a garden killer as freezing conditions will occur during the overnight and morning hours. There is a Frost Advisory for tonight and Tuesday morning and a Hard Freeze warning for Tuesday night to Wednesday morning. The front is mainly dry in nature but a few rain showers to snow flurries will be possible tonight and Tuesday morning in northeastern to eastern NV. Even if precipitation occurs it will lead to no significant accumulations of anything. Wednesday will see a dry northerly flow across NV with a high pressure trying to build back into region. This will produce fair weather with increasing temperatures. .LONG TERM...Wednesday night through Monday Late Wednesday through Thursday, the closed low centered over Utah/Arizona are lifts northeasterly at a very slow pace. Its influence on our region is felt through the day on Thursday with a breezy northeasterly flow aloft, providing a continuous flow of cooler and drier air. Higher pressure starts to build in later that evening as the Pacific ridge fills in the southwestern region. This ridge is expected to linger through the weekend, and into the start of next week. Guidance is struggling to paint a clear picture as to how the pattern changes after that, but that is to be expected this far out. It is worth saying that the mid- and upper-level flow takes on a more active pattern than what we have seen now for what feels like countless weeks. It’s just going to be a matter of where this unfolds. && .AVIATION...VFR at all terminals for the next 24 hours. Strong gusty winds will be present at all terminals today and lasting through Tuesday morning. The winds will generally be gusting in the 30s to 40s kt range with occasional stronger gusts possible. Haze will be departing the area making for clear skies. && .FIRE WEATHER...A cold front is passing through NV bringing cooler conditions and higher RH along with strong gusty winds. The winds will be strongest today weakening somewhat during the overnight and early Tuesday before abating Tuesday afternoon and evening. Ahead of the cold front today the winds and low RH will create critical fire weather conditions for all zones. The critical fire conditions will continue in fire zones 426 and 427 during the overnight and Tuesday. A Red Flag Warning remains valid for these critical fire weather conditions. The cold air behind the cold front will see RH rise above critical levels starting in the north and working southward through today and Tuesday. As this is a mainly dry front little to no significant precipitation is expected outside the peaks of northern NV mountains. && .LKN WATCHES/WARNINGS/ADVISORIES...
