Heat Heads North
6/20/2008 8:49 AM
The blistering heat that has blanketed the Desert Southwest this week will spread into the Intermountain West this weekend, while marine air keeps conditions comfortable along the West Coast.

The Southwest Regional News story reports dangerous heat today will spread from the central valley of California to Texas. Excessive heat warnings are in effect from Southern California to the Desert Southwest.

Death Valley, Calif. reached a high of 120 degrees Thursday, while a number of daily temperature records in California were broken or tied:
  • Palm Springs: 116° (tied record from 1989)
  • Thermal: 118° (old record 114° in 1968)
  • Woodland Hills: 109° (old record 105° in 1989)
  • Ramona: 102° (tied record from 1989)
Marine air will result in cool temperatures along the West Coast, while heat will push into the Northwest interior and Intermountain West. Temperatures Saturday will reach the 80s in the mountains of Montana, but cooler air will arrive Sunday.

The heat across the Desert Southwest will ease somewhat next week as the jet stream shifts south and east.
