Temperatures in Northern California will see a slight dip on Tuesday, but a warming trend is expected to bring above-average heat to the region in the coming days. Forecast highs in the 80s are predicted for next week, with the potential for triple-digit temperatures in Phoenix by the end of the week.

Why it matters

The abnormal warmth forecast for Northern California and the Southwest is concerning, as it could lead to increased energy demands, health risks, and strain on natural resources. This trend is part of a broader pattern of climate change-driven temperature extremes impacting the region.

The details

A jet stream dropping south is bringing a brief period of cooler temperatures to Northern California on Tuesday, with forecast highs in the 70s. However, high pressure is expected to move in for the rest of the week, driving temperatures up into the low 80s by the end of the week - approaching daily record highs. This heat risk is forecast to spread across the entire Northern California region, including the foothills and Sierra Nevada mountains.
