An Extreme Heat Warning has been posted for the Coachella Valley from Wednesday through Saturday, with high temperatures expected to exceed 105 degrees each day. The Valley will see plenty of sunshine, very low relative humidity, and above-normal high temperatures just above 100 degrees on Tuesday. As an expanding upper-level ridge of high pressure centers itself over Southern California, Valley midday temps are expected to peak anywhere between 105 and 109 degrees on Wednesday through Saturday.

Why it matters

The extreme heat poses a significant risk to public health and safety, especially for vulnerable populations. New high temperature records are expected to be set each day this week, not only in the Coachella Valley but across much of the Southwest.

The details

The expanding upper-level ridge of high pressure will lead to clear skies, light winds, and low dew points of around 30 degrees each afternoon from Wednesday through Saturday. While a weakening trough of low pressure next Monday will slightly pull down the temperatures, the relief is expected to be minimal.

• On Tuesday, the Valley will see high temperatures just above 100 degrees.
• From Wednesday through Saturday, high temperatures are expected to peak between 105 and 109 degrees.
• Next Monday, a weakening trough of low pressure will slightly pull down the temperatures, but only slightly.

What they’re saying

What’s next

Next week Monday, a weakening trough of low pressure will play a role in pulling down those temps... but only slightly.
