Sacramento, California – A major pattern shift will bring cooler temperatures and the potential for afternoon thunderstorms to Northern California beginning late Sunday and continuing through at least Thursday.
According to the National Weather Service in Sacramento, a slow-moving weather system is expected to sweep across the region late Sunday night into Monday, stalling through midweek. The system will push moisture and instability into the northern Sacramento Valley, Coast Range, and Sierra, increasing the chance for light rain showers and isolated thunderstorms.
While rainfall amounts are expected to be light overall, the highest chances for measurable precipitation will occur in the northern Sacramento Valley and the surrounding mountains. Afternoon and evening storms may also develop daily through Wednesday, though forecasters note there is high uncertainty in timing and coverage.
Travelers should monitor conditions closely, especially in mountain areas where brief downpours could reduce visibility and create slick roadways. Residents are advised to limit outdoor activity during potential thunderstorms and secure outdoor items that could be affected by gusty winds.
This early September system marks a sharp change from recent dry conditions, and additional updates or advisories may be issued as confidence increases in the storm’s impact.
