If you’ve stepped outside in Midtown lately, you’ve probably noticed the air feels a bit... different. Not exactly the bone-chilling dampness we usually expect by mid-January. Honestly, the 10 day weather forecast sacramento california is looking more like an identity crisis than a standard winter outlook. We’re currently sandwiched between a ridge of high pressure and the lingering memory of that massive atmospheric river that dumped inches on us earlier this month.
Basically, the Valley is in a holding pattern.
Right now, as of Thursday night, January 15, things are calm. Maybe too calm. The temperature is sitting at a crisp 46°F with a humidity level of 91%. If you’re driving near the Sacramento River tomorrow morning, watch out. Dense fog is basically a guarantee when the moisture is this high and the wind is only breathing at 3 mph.
The Forecast Breakdown: Sun, Clouds, and That One Random Rain Chance
Looking at the next week and a half, we aren’t seeing any major "Tule fog" lockdowns or massive flood watches, which is a relief. But it's not all clear skies either. Here is the vibe for the coming days:

Tomorrow, Friday, January 16, starts off sunny with a high of 59°F. It’s that classic Sacramento winter day where you need a heavy coat at 7:00 AM and find yourself carrying it by noon. The low drops back to 40°F, so keep the frost blankets on the citrus trees.
Saturday turns cloudy. Highs stay at 59°F, and the wind stays negligible. It’s a gray, "stay inside and order Pho" kind of day. Sunday, January 18, actually looks like the winner of the week—sunny skies return with a high of 61°F. It’s arguably the best window for a run along the American River Parkway before the clouds move back in for Monday.
The start of the work week brings "mostly cloudy" conditions. Temperatures hover between 57°F and 59°F for the highs, while lows stay remarkably consistent around 40°F. You won't see much change until we hit next Sunday, January 25. That’s when the models show a slight shift. We’re looking at a 20% chance of rain and a bit more wind—about 5 mph from the southwest. It’s not a storm, but it's enough to mess up your car wash.

Why the Valley is Foggy While the Hills are Warm
There’s this weird phenomenon happening right now called a temperature inversion. The National Weather Service in Sacramento has been talking about it all week. High pressure is sitting on top of us like a heavy lid. This traps the cold, moist air in the Valley (hello, fog!) while the Sierra foothills and mountains are actually enjoying warmer, drier air.
If you’re tired of the gray, drive up to Placerville or Auburn. You’ll literally climb out of the soup and into the sunshine.
Is the Atmospheric River Over?
We saw a lot of drama in early January with the "Cold Atmospheric River" that brought those 2-inch rain totals to the city. For the next 10 days, that tap is mostly dry. While we have a lingering 10% chance of rain most days this week, it’s mostly just "nuisance moisture."

Wait. Don't get too comfortable.
Long-range climate trends for 2026 suggest a shift toward El Niño by late summer. But for this winter, we’re dealing with the leftovers of a weak La Niña. Historically, that means January and February can be wild cards. We’re currently "drought-free" for the first time in a quarter-century, thanks to those December and early January deluges. Our reservoirs are sitting pretty at 129% of average.
The real concern isn't the rain right now—it's the "snow drought" in the Sierra. The snowpack is only at about 71% of average. We need more than just a few cloudy days in the Valley; we need those big, cold systems to return if we want to keep the water flowing through the summer.
Actionable Steps for the Week Ahead
Don't let the "sunny" icons fool you. This 10-day stretch requires a bit of strategy.
- Check your tires. If we do get that 20% rain on the 25th, the roads will be slick from the oil buildup during this dry spell.
- Clean your HVAC filters. Foggy, stagnant air in the Valley can trap pollutants. If your allergies are acting up, that’s why.
- Plan your outdoor tasks for Sunday. It’s the warmest and clearest day in the current 10-day window.
- Drive with low beams. If you're commuting on I-5 or Hwy 99 during the early morning, the fog will be thick. High beams just reflect off the water droplets and make it harder to see.
The Sacramento weather is staying remarkably steady for now. Highs in the upper 50s, lows near 40, and just enough cloud cover to keep things interesting. Enjoy the break from the heavy rain, but keep the umbrella in the trunk just in case that Sunday system decides to overachieve.
