Through Tuesday, Phoenix Nears 110 and Las Vegas Hits 100 as the Southwest’s Second Heat Wave Brings Worsening Drought and Rising Fire Risk
SOUTHWEST UNITED STATES — The second heat wave of the year is fully underway across the Southwest, with Phoenix approaching 110 degrees and Las Vegas reaching 100 for the first time in 2026, as a powerful surge of heat dominates the region through Tuesday, May 12.
Cities Baking Under the Heat Surge
The heat dome is centered over a massive stretch of the West, pushing temperatures to levels not seen since last summer. Cities within the core heat zone include:
- Phoenix and Tucson — Phoenix near 110 degrees
- Las Vegas — hitting 100 for the first time this year
- Reno, Elko, Salt Lake City, and Cedar City — all within the very warm to hot zone
- Fresno, Redding, Medford, and San Francisco — elevated heat along the California corridor
- Moab, Flagstaff, and Albuquerque — southeastern edge of the heat footprint
What Makes This Heat Wave Dangerous
Beyond the raw temperatures, three compounding factors are making this event especially hazardous:
- Highs running 15 to 25 degrees above historical average across the region
- Worsening drought conditions being intensified by the heat
- Increased fire risk as hot, dry air spreads across already parched landscapes
Records on the Line Through Tuesday
Multiple locations are expected to challenge temperature records through Tuesday. The combination of an unusually strong high-pressure system and the ongoing drought is creating near-summerlike conditions across a broad area of the Southwest well ahead of the calendar.
