An upper level ridge is expected to cause well above normal temperatures this week, mainly today, with the Valley seeing a 60 to 90% chance for highs of 95 degrees or higher. These temperatures will bring about a moderate risk of heat-related illnesses to those sensitive to heat, such as older adults (65+), infants, athletes, outdoor workers, those without effective cooling, and those with chronic diseases. There is some risk to the general population. A slight cooling trend can also be seen for the rest of this week, though temperatures are still expected to be above 90 degrees.
