Sacramento rolled out of bed Wednesday, May 6, under a gray lid of low clouds and a noticeable chill, with temperatures stuck in the mid‑50s across the city. The cool start will not last. Sunshine is expected to break through by afternoon, sending highs up to around 78°F with a light southwest breeze for the drive home.
Afternoon And Evening
By midday, mostly sunny skies should take over, although the Sierra and nearby foothills still have a shot at isolated showers and a few mountain thunderstorms through this afternoon and evening. Most valley neighborhoods are expected to stay dry, and any showers that do develop should fade out overnight as temperatures slip back into the low‑50s.

Late Week Heat
The real story hits late this week, when temperatures make a fast climb. Highs jump to about 82°F on Thursday, around 84°F on Friday, then push into the low‑90s Saturday and Sunday. Forecasts point to a hotter punch early next week, with highs potentially near 98°F on Monday, May 11, and around 99°F on Tuesday, May 12. According to the NWS Sacramento, the Valley moves from a Minor heat risk Thursday and Friday to a more widespread Moderate risk from Saturday into next week, with a growing chance of triple‑digit afternoons in parts of the valley.
Impacts And Safety
Minimum relative humidity is projected to drop into the 20s and teens by the weekend, and a north breeze could gust 15 to 25 mph on Saturday. That combination bumps up localized fire‑weather concerns in dry grasses and foothill brush. Officials recommend shifting strenuous outdoor work to mornings or evenings, staying hydrated, watching for signs of heat illness, and checking in on older neighbors and pets.
