High pressure is now the dominant feature in our forecast, and that will result in warm and mostly dry weather through this weekend. Temperatures are starting out cooler than yesterday for most of our region this morning, but are still above average for this time of year. There is potential for some fog development early today that could impact visibility for drivers, but the north winds have kept the impacts low for our region this morning. Fog is going to be an issue for drivers heading south into Yuba City or Sacramento this morning. Temperatures are in the 40's to low 50's for the start of your Thursday in the valley, and mountain areas are starting out in the 20's to 40's. Skies will be mostly sunny across our region through the day. Winds are projected to be out of the north to around 10mph through this evening. High temperatures will range from the upper 60's to mid 70's in the valley, low to high 60's in the foothills, and lower 50's to mid 60's in our mountain areas this afternoon.
A weak disturbance will track through to our north on Friday, but will have limited impact on your Friday forecast. An increase in clouds and a modest drop in high temperatures are the most likely changes on the way for your Friday, but we may also see a chance for very light precipitation in areas closest to the Oregon border Friday afternoon and evening. High pressure will then build back into northern California as we head into your weekend. That will result in dry weather and well above average temperatures. Projections put the valley in the upper 30's to mid 40's overnight and high temperatures in the upper 60's to mid 70's for both days this weekend. Foothill areas can expect low temperatures in the 40's to lower 50's and high temperatures in the 60's, and mountain areas can expect low temperatures in the upper 20's to lower 40's in the mornings and high temperatures in the 50's to 60's in the afternoons this weekend. Partly cloudy to mostly sunny skies will be in store for both Saturday and Sunday.
On Sunday we'll start to see north winds picking up, and stronger north winds are in our forecast for the start of next week. Sustained winds of around 20 to 25mph out of the north are possible, and we could be dealig with gusts in the 35 to 40mph range. Temperatures will end up slightly cooler than the weekend for your Martin Luther King Jr. Day forecast on Monday, but we'll still top out in the mid to high 60's in the valley. Well above average high temperatures and breezy north winds will be in store through the middle of next week. The longer range models are bringing the next potential for wet weather back into our forecast on Thursday night into Friday of next week, but confidence is low on showers actually occuring. We'll continue to track the latest information and will update the potential for rain as we get closer to that time frame.
