Northern California is experiencing a stretch of unseasonably warm weather this weekend, with temperatures in some areas nearing the 100-degree mark. According to the National Weather Service (NWS) in Eureka, this heat wave is expected to continue through Sunday, driven by a high-pressure system building from the Eastern Pacific. However, a more typical cool and moist fall-like pattern is expected to develop by next week, with a slight chance of rain by the end of the forecast period.
Heat Wave Affects Interior Counties
Interior counties, including Mendocino and Lake, are experiencing the brunt of the heat. Temperatures in these areas are expected to reach the mid to upper 90s, with isolated valleys possibly nearing 100 degrees. The NWS has issued a moderate heat risk warning for these regions, cautioning that sensitive populations, particularly those without adequate cooling or hydration, may be at risk.
In addition to the heat, broad offshore winds are expected to persist, keeping humidity levels low and pushing the heat closer to coastal areas. Temperatures along the coast from Cape Mendocino to Shelter Cove are forecasted to exceed 75 degrees, which is well above average for this time of year. Even Fort Bragg and Point Arena, typically cooler, are expected to see temperatures in the low 70s.
