Alert! Heat wave across Western USA

A punishing and long-enduring heat wave is intensifying in parts of the West and Southwest, with heat warnings and advisories in effect across seven states Wednesday. The heat will not relent until late in the weekend.

Threat level: In the coming days, 40 million are likely to see temperatures reach or exceed 100 degrees.

Why it matters: The extreme heat is unusually intense for June, and is aggravating already dire drought conditions that could lead to another devastating wildfire season.

The details: Overnight minimum temperatures in Las Vegas barely slipped below 90°F early Wednesday, and daytime highs are anticipated to approach the city’s all-time record of 117°F today through Saturday.

In Phoenix, the low temperature Tuesday night into Wednesday warming was a stifling 91°F.
The heat wave is the result of a sprawling area of high pressure at the surface and aloft, also known as a heat dome. It’s deepening the already extreme drought across the West, and adding to the significant wildfire danger across the region.
