KEY MESSAGES

* Hot and dry conditions prevail into next week, with triple digit heat to lower valleys Friday and Saturday.

* Hazy skies with areas of smoke from fires in Oregon will reduce air quality at times across much of northwest and west central NV, with patchy smoke near and east of the Elephant Fire. * Typical afternoon winds are expected each day, with potential for elevated fire weather concerns in isolated locations.

DISCUSSION

Summer heat is here to stay, at least it will feel that way, as we say goodbye to July and hello to August. This weekend, a robust ridging pattern across the southwestern portion of the CONUS has heating and subsidence locked in place. This will bring widespread 100+ degree readings for western Nevada valleys, with Sierra valleys heading for the mid 90s. Additionally, overnight lows will only fall into the mid 60s Friday night. As a result, a Heat Advisory will commence midday Friday and remain the story into Sunday morning. This heating pattern looks to stick around well into the initial days of August, since this ridge seems determined to hang around the region. The NBM has consistently shown this heating pattern, with little variance on outcomes. While a shortwave looks to take temperatures down by a couple degrees on Sunday and Monday, 100s are still on the table. Once the shortwave moves along, our regularly scheduled heating will resume, bringing Major HeatRisk back around midweek.

Winds will largely follow a typical summertime zephyr pattern, with the Sunday-Monday shortwave increasing winds slightly. Gust speeds will range 25-30 mph each afternoon, and mostly be blowing out of the SW-W.

Smoke may filter into valleys near Reno due to the Elephant Fire, with other areas potentially affected by smoke from nearby fires across the western states. HRICH

AVIATION

* VFR conditions are forecast for all terminals, with daily afternoon gusts 20-25 kts between 21z-03z. Increasing temperatures will bring density altitude concerns to area terminals through the weekend. Smoke from nearby fires may also produce slantwise visibility concerns daily. HRICH
