After days of record-breaking temperatures, California's October heat wave is beginning to retreat. A cooling trend is expected to begin Tuesday through the rest of the week.

Some cities in Northern California are seeing temperatures in the upper 90s and lower 100s. Temperatures are generally in the mid-80s this time of year.

Similarly temperatures in Yuma, Arizona broke a 28-year record, reaching 112 degrees Fahrenheit, while more than 50 other heat records were broken throughout the American Southwest on that same Wednesday. Overall at least 125 locations from the Rocky Mountains to the West Coast have broken temperature records since the start of the month.
