SACRAMENTO, Calif — The last push of showers moves through tonight with the wet weather winding down by midnight.
Light winds and recent rain will set up the valley for another morning of fog.
A Dense Fog Advisory will be in effect from 2 A.M. until 10 A.M. with visibility of less than a quarter of a mile in some areas. Be prepared for these conditions on the morning commute.

After the fog lifts, mostly sunny skies are expected. Temperatures warm a bit more too.
Highs around the valley will be in the low to middle 60s. If you are planning to get out and enjoy the dry weather, be cautious around areas rivers.
The Sacramento River in particular is high due to the rain but also because a good bit of water is being released from Shasta. Particular caution is needed around the Sacramento River the next few days because of the increased flow. Every passive weir on the Sacramento is flowing.
Temperatures stay on the warmer than average side through the weekend with highs on Saturday near 70°!
Tracking another round of possible showers late Sunday but this is far from a certainty and as far as rain totals, there is some variance in models. This storm looks to be far less potent than what we dealt with this week.
The overall weather pattern will be shifting over the next couple of weeks. The Pacific-North American Pattern – which tells us if the blocking high pressure is in the east Pacific (positive values) or in the Gulf of Alaska – is expected to shift strongly negative indicating the opportunity for drier but much colder storms as we roll into March.

The Pacific-North American Pattern tells us where the blocking high pressure is. Strong negative values mean we can see colder storms form the north.
The high pressure that has been steering atmospheric rivers into California from the Pacific is expected to move further west. This will largely cut off the Pacific moisture pipeline but allow colder storms to drop down from Canada. While these storms with a northern origin are usually much drier than the atmospheric river storms, they’re much colder. This allows for more snow and lower snow levels.
It’s not a done deal that it’ll be rainy to start next month, but the pattern change indicates that it’s likely.
