Triple-digit temperatures bake the Valley

PHOENIX -- Temperatures will soar past the century mark for most of next week as high pressure builds into the region.

On Monday, temperatures in the Valley will start out in the mid 70s. By late afternoon, we’re forecasting a high of 102 in Phoenix. The average high temperature for this time of year is 94 degrees.

That streak of low 100s will continue through at least Thursday. While our heat won’t threaten any records, temperatures for most Valley locations will run close to 10 degrees warmer than normal for this time of year.

Isolated showers along Eastern Arizona and the Mogollon Rim are possible both Monday afternoon and Tuesday afternoon as an area of low pressure meanders in Mexico. Moisture from this system, combined with daytime heating, will allow clouds to billow over the mountains before the showers begin to fall. It does not look like any of that moisture will make it into the Valley.

The low fizzles out on Wednesday, and a drier air mass from the west is expected to move in, ending our mountain shower chances.

We may have localized gusty winds for both the Valley and the Mountains Tuesday and Wednesday.

By Friday and into the weekend, temperatures will gradually cool and return to seasonal norms.
