Feel free to leave the umbrella at home today, but be prepared to deal with fog on your way out the door this morning. Fog has become more prevalent this morning, and will limit visibility down to around a mile in many parts of Northern California. Please allow for extra time to get to where you're going early on today. Temperatures are starting out in the mid 40's to low 50's in the valley this morning, and in the low 30's to mid 40's in the mountains. Skies are starting out somewhat cloudy, but are expected to clear through the day. High temperatures will end up in the low to mid 60's in the valley, and in the high 40's to low 50's in the mountains. Winds will be up to 10mph out of the North.
The warming trend will ramp up this weekend, and dry weather will persist. Most valley areas will be in the mid 60's over the next few afternoons. Morning fog will continue to be an issue for Saturday and Sunday. Drivers are urged to be cautious as visibility will likely be impacted. Looks like we're going to stay dry, but get a few degrees cooler for your Martin Luther King Jr. holiday. Showers are expected to return to coastal areas Monday afternoon, and will spread into the Northern Mountains on Monday night.
Wet and cooler weather returns to all of Northern California on Tuesday. Wednesday will likely have lingering showers in the mountains, but less than impressive precipitation in the valley. A colder and wetter system will return to Northern California on Thursday. It's not clear where snow levels will end up with that system, but it seems safe to say they will be low enough to impact mountain travel. We will continue to track that system ahead for the end of next week, and will give you a better break down for what you can expect when models come into better agreement.
