Here’s what to expect in Sacramento:
How high will temperatures be?
Most of the Valley and northeastern Sierra foothills will experience heat risks from Tuesday through Thursday, with high temperatures potentially exceeding 100 degrees.
Overnight low temperatures will remain warm, ranging from the high 60s to mid-70s, the weather service said.
What’s in the weather forecast for Sacramento?
On Monday, Sacramento residents can expect clear, sunny skies and a high temperature of 86 degrees, according to the latest seven-day weather forecast. The overnight low temperature will be 63.
On Tuesday, the forecast shows a high temperature near 102 and a low of approximately 71 degrees. Winds could range from 5 to 14 mph, with gusts potentially reaching up to 25 mph.
Wednesday will see a high near 104 degrees and a low around 66.
Thursday’s forecast predicts a high near 99 degrees and a low around 62.
On Friday, the high will be approximately 94 degrees, with a low around 58.
Weekend temperatures are expected to reach a high of 93 degrees, with a low of about 61 degrees on Saturday.
What does heat risk mean?
Starting Tuesday, Sacramento’s heat risk will range from major to moderate.
The heat risk scale, or the weather service’s HeatRisk Prototype, provides a forecast that shows the likelihood of heat-related problems occurring.
The scale calculates how hot it is compared to normal, how long the heat lasts, and if it’s likely to cause health issues based on data from the U.S. Centers for Disease Control and Prevention. It ranges from 0, meaning there’s little or no heat risk, to 4, indicating an extreme heat risk.
The heat risk is projected to be a 3, or major, on Tuesday and Wednesday and a 2, or moderate, on Thursday and Friday.
According to the weather service, major heat risk “affects anyone without effective cooling and/or adequate hydration.”
Moderate heat risk “affects most individuals sensitive to heat, especially those without effective cooling and/or adequate hydration.”
Who’s at risk?
Vulnerable individuals include those who are pregnant, newborns, children, older adults and those with a chronic illness. These groups are more at risk due to age and conditions that make it difficult to regulate high temperatures.
“Drink plenty of fluids, stay in an air-conditioned room, stay out of the sun, and check up on relatives and neighbors,” the weather service said in the warning. “Do not leave young children and pets in unattended vehicles.”
