Temperatures in the 90s are nothing new to the northern San Joaquin Valley. But having them in March, as expected this week, is unusual and potentially dangerous.
An exceptionally strong ridge of high pressure will bring record-breaking heat to the entire region, the National Weather Service said. Temperatures in the San Joaquin Valley are likely to reach 90 degrees by Tuesday and 95 by Friday. That's 20 to 25 degrees above normal.
