Fog has blanketed the Sacramento Valley this morning, prompting the National Weather Service (NWS) to issue a Dense Fog Advisory in effect through 10 am for the southern Sacramento Valley, Delta, and northern San Joaquin Valley. Motorists in the area should exercise caution, as the dense fog is particularly heavy near the Sacramento and San Joaquin rivers and the Delta region. The NWS advises drivers to allow extra travel time, use low beam headlights, and maintain a safe distance from other vehicles on the road.
According to the NWS Sacramento weather forecast, sunny conditions are expected to remain largely unchanged over the next week, as dry weather persists and Valley fog continues. The NWS reported a 40 to 70 percent chance of visibility reductions below a half mile overnight and into this morning across the Delta, portions of the central and southern Sacramento Valley, and the northern San Joaquin Valley, with the highest likelihood in the southern Sacramento and northern San Joaquin valleys. Temperatures are expected to remain mild for this time of year, with afternoon highs ranging from the low 60s to the mid-70s before a slight dip over the weekend.
Moving into the middle of next week and beyond, a shift may be on the horizon. The NWS forecast discussion hints toward a flattening of the ridge, which may lead to cooler temperatures and a slight potential for light mountain precipitation late next week. Although the probability of precipitation greater than 0.1 inches sits at a modest 10-25% for the mountains late next week. The chances for morning fog and low clouds appear to be a consistent part of the weather pattern for the area.
For aviators, the NWS warns of lingering IFR/LIFR conditions in the central/southern Sacramento Valley, Delta, and northern San Joaquin Valley through about 20z today. Come evening, around 05z Saturday, pilots can expect the fog to roll back in with similar coverage as experienced this morning. Surface winds in lower elevations are expected to remain tame, below 12 knots, while the Sierra and Southern Cascades could face stronger E-NE wind gusts up to 25 knots.
