Heat Wave to Build Over California This Weekend

Heat is forecast to build over California this weekend with the hottest weather of the season so far possible for some areas.

As the storm responsible for cool, windy conditions in the region to start the week pushes across the middle of the nation, temperatures will rebound to warm levels as the week progresses. The windy weather will ease later in the week as well.

The hottest part of the weather pattern will settle in over the weekend and could feature the first 100-degree temperatures of the season for Sacramento.

The heat will reach out of California and into Nevada and Arizona as well.

This weekend, areas from Downtown Los Angeles to the Inland Empire, the San Joaquin and Sacramento valleys, Las Vegas, Phoenix and some of the mountains in between could have their highest temperatures of the season so far.

Temperatures surged above 100 over the Southern California deserts during the middle of May. It is possible that this heat will equal or even eclipse those readings.

The only cool spots will be right along the Pacific coast and over the high country in the Sierra Nevada.

In some cases over the interior, temperatures may challenge record highs for the date on one or more days.

During next week, there is a chance that a weak storm system will form in the vicinity of Southern California.

In this setup, while temperatures would throttle back over much of California, Nevada and Arizona, spotty thunderstorms could develop over the mountains.

Depending on the moisture available to the storms, dry lightning could ignite wildfires. The same pattern next week could pump sunshine and heat into the Northwest.
