Be prepared for the potential for patchy fog limiting visibility on your morning commute, and very pleasant conditions on tap in your Thursday forecast. High pressure has built into northern California over the last 24 hours, and will dominate our forecast today. This will leave us with dry weather, sunny skies, and warmer temperatures ahead for your Thursday. Some patchy fog will be possible early today, but sustained north winds have limited fog development in the valley. Some wind sheltered mountain areas will likely have bigger impacts to visibility from the patcy fog this morning. Skies are clear overhead to start your Thursday, and we'll have sunny to mostly sunny skies through this afternoon. Temperatures are starting out in the 50's in the valley, 50's to lower 60's in the foothills, and 30's to low 50's in our mountain zones Thursday morning. Winds will be out of the north to around 10mph today, but we could have periods of gusts up to around 20mph. High temperatures are projected to top out in the mid 70's in the valley, mid 60's to around 70 degrees in the foothills, 60's in the Sierra, and upper 60's to mid 70's in the Northern Mountains this afternoon. Thin clouds will begin to increase across northern California tonight as low pressure pushes through the Pacific Northwest.
Partly cloudy skies will be ahead for northern California on Friday as low pressure tracks towards the Pacific Northwest, and the high pressure that's bringing our sunshine and warmer temperatures begins to break down. Most models are keeping us dry through Friday night, but do have our temperatures dropping by a few degrees on Friday afternoon. This is great news for anyone hoping to take their little ghouls and goblins out to Treat Street in Downtown Chico Friday afternoon. Valley temperatures will top out in the lower 70's on Friday afternoon, while foothill and mountain areas still mostly top out in the 60's. Winds will mostly stay on the lighter side, and will shift to become out of the south. The system that's bringing the increasing clouds to our region on Friday will bring the potential for showers to northern California late Friday night into Saturday morning. Light showers will be possible across most of our region through the day on Saturday, but most models have those showers wrapping up Saturday night. We'll also be cooler as we head through this weekend, with mid 60's projected for the valley both Saturday and Sunday. Foothill and mountain areas will top out in the 50's to lower 60's both days this weekend. Sunday looks to be partly cloudy, and we'll have a slight chance for some light showers. Most models are keeping us dry for Halloween on Sunday, and all models are showing dry conditions during Trick or Treating time in the late afternoon and evening.
The next wet system will approach the West Coast Sunday night into Monday, and modest showers are expected across northern California through the day on Monday. Temperatures will also be cooler for the start of next week and November, with valley areas only topping out in the 50's. Foothill and mountain areas will end up in the upper 40's to mid 50's on Monday. Tuesday will be cloudy, a little warmer, and will have a lingering chance for some light showers early in the day. The next wet system will move in Wednesday and could persist into Thursday. We'll stay cool and cloudy with more chances for showers as we head through next weekend.
