Sacramento's stretch of warm October weather is expected to give way to a noticeable cooldown early next week, with afternoon temperatures falling 18 degrees between Friday and Tuesday while dry conditions continue.
According to the National Weather Service forecast for Sacramento, temperatures will reach approximately 88 degrees Friday before gradually declining through the weekend. By Monday and Tuesday, afternoon highs are expected to settle near 70 degrees, marking a substantial change from the late week warmth.
Unlike other parts of the Pacific Northwest facing rain chances, Sacramento's supplied forecast keeps precipitation out of the picture through Tuesday.
Weekend Warmth Continues Before Temperatures Fall Saturday will bring another sunny afternoon, with temperatures reaching approximately 87 degrees across the Sacramento forecast area.
That keeps the city close to Friday's projected high of 88 degrees, extending the warm stretch into the weekend.
Saturday night will remain clear, with temperatures falling near 55 degrees.
Sunday marks the beginning of the more noticeable cooldown, with afternoon temperatures expected to reach approximately 80 degrees.
Although still warm, Sunday's high would be eight degrees below Friday's peak.
Mostly clear skies continue Sunday night, with temperatures dropping near 51 degrees.
The dry conditions and sunshine should provide favorable weather for outdoor activities throughout the weekend, particularly during the cooler morning and evening hours.
Temperatures Settle Near 70 Early Next Week The cooling trend becomes more pronounced Monday, when Sacramento's afternoon high is expected to reach approximately 71 degrees.
That represents a 17 degree decline from Friday's projected temperature.
Tuesday brings little change, with mostly sunny skies and a high near 70 degrees.
The National Weather Service does not indicate rain, thunderstorms or significant wind impacts in the supplied Sacramento forecast through Tuesday.
Overnight temperatures also trend cooler, with Monday night's low expected near 49 degrees.
While NOAA's national discussion highlights a separate surge of colder air across portions of the central United States late this week, that outlook does not establish the cause of Sacramento's cooling.
The available forecast supports a transition from upper 80s warmth to lower 70s afternoons in Sacramento. Temperatures elsewhere across the broader Sacramento Valley may vary.
