A moderate to strong southwest flow aloft and daytime heating enhanced afternoon and evening breezes with gusts in the 20-30 mph range with higher gusts in wind prone areas. These breezy conditions brought periods of isolated critical fire weather conditions, and choppy conditions across area lakes.

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 Reno, NV wrote its last area forecast discussion before the first event at Jul 27, 12:33 PM PST, 2 hours 27 minutes earlier.
Area Forecast Discussion National Weather Service Reno NV 133 PM PDT Thu Jul 27 2023 .SYNOPSIS... Quiescent, warm weather with breezy afternoons and very dry conditions will prevail through the weekend. A slight uptick in winds on Saturday may yield short periods of critical fire weather conditions and choppy lake waters. Chances for showers and storms return next week. && .DISCUSSION... Quite a beautiful late-July day today as blue skies and the Sierra provide a nice backdrop to downtown Reno as seen out of the office window. Regional temperatures vary from the 70s and 80s in Sierra valleys to the mid-80s and 90s for lower western Nevada locales. Temperatures will continue to climb in the next few hours, reaching the 80s for Sierra communities and 90s for western Nevada. While not excessively hot, such temperatures can be sneaky and induce heat health impacts if precautions, such as drinking water and limiting strenuous outdoor activities, are neglected. Meanwhile, typical breezy winds arrived a bit earlier today compared to recent days per latest observations, but gusts will top out in the 25-35 mph range this afternoon before tapering off in the evening. Seasonable late-July heat and breezy afternoon winds will be the theme through the weekend as the synoptic pattern remains rather stagnant. Winds may strengthen a bit Saturday afternoon and evening with gusts of 30-40 mph, allowing for short periods of critical fire weather conditions and choppy lake waters. Next week, ensembles continue to advertise an increase in shower and thunderstorm potential around midweek as moisture aloft filters into the region. However, blended guidance paints just a 10-20% chance of storms, favoring areas generally south of US-50. -Salas && .AVIATION... VFR conditions will prevail with typical southwest breezes each afternoon. A belt of 30-35 kt FL100 winds will develop from the Tahoe Basin region into western Nevada overnight. Some LLWS and mountain wave turbulence will be possible between 09Z to 15Z. Otherwise, quiet and breezy weather lingers into the weekend. -Salas && .FIRE WEATHER... Daily breezy winds and very low humidity will maintain elevated fire weather conditions each afternoon. Winds strengthen a skosh for Saturday afternoon and evening, promoting critical fire weather conditions at times from northeast California into western Nevada. Poor overnight recovery will continue to further cure vegetation in the valleys and foothills over the next several days. Next week will feature an uptick in thunderstorm potential (10-20%), particularly south of US-50. With that being said, only a marginal, lower-end fire environment will exist each day (including Saturday) until a stronger, more organized wind episode occurs and/or heavier mountain fuels become much more receptive to ignition and spread. -Salas && .REV Watches/Warnings/Advisories...
