Independence Day celebrations throughout the Sacramento region should mark the last of the week's triple-digit temperatures.
"We're gonna have one last hot day today," said Craig Shoemaker, meteorologist for the National Weather Service.. "We're forecasting a high temperature today of 107 for Sacramento."
The record high for today's date in Sacramento is 110 degrees in 1991.
Although a 15 percent chance of rain was forecast for the Sacramento region, Shoemaker said showers are "very isolated" in the morning and afternoon hours, and the systems should shift east of the Sierra crest later this afternoon.
Cooler weather is expected Friday, with a high of 94 degrees and a strong Delta breeze sweeping through in the afternoon or the evening. The weekend highs are expected to hover around the 90s, with cool nights reaching lows in the 60s.
Shoemaker said the weekend could be even cooler than currently forecast if the Delta breeze is stronger than expected, and 80-degree weather is "in the realm of possibility" for Saturday.
Temperatures in mountain areas today should be between the 80s and the lower 100s.
