Sunny skies and slightly below average temperatures are ahead for your Tuesday. High pressure centered to our East will be the main driving factor in our forecast today, but we still have an area of low pressure passing through to our North. We're starting out with clear skies over Northern California this morning and we'll be staying sunny today. Temepratures are starting out in the high 50's to mid 60's in the valley and foothills, and in the 40's in most mountain areas. Winds are light and out of the Northeast this morning, but will shift to 10mph out of the Northwest this afternoon. Humidity is expected to dip into the 10 to 25 percent range this afternoon, with the lower values in the northern zones of the valley. High temperatures are projected to top out in the mid to high 90's in the valley, in the mid to high 80's in the foothills,and in the mid 80's for most mountain areas this afternoon. Due to the lighter winds and slightly higher humidity, fire danger will be in the moderate range this afternoon.
High pressure is expected to build to the West from the Four Corners region over the next few days and that will result in warming temperatures over Northern California. Slightly warmer high temperatures are expected on Wednesday. Valley areas can expect high temperatures to range from the high 90's to low triple digits, while foothill and mountain areas end up in the mid 80's to low 90's from Wednesday through Friday. Skies will be sunny to mostly sunny and the vast majority of our region will stay dry through the end of this week. There will be a slight chance for some light showers and thunderstorm activity in areas closest to the Oregon and Nevada borders on Thursday evening, but we'll otherwise be staying dry.
High pressure continues to build as we head into your weekend and that will result in triple digit heat across the entire valley and sunny skies. Foothill areas can expect high temperatures in the low to mid 90's this weekend, and mountian areas can expect high tmeperatures in the high 80's to mid 90's through your weekend. We'll be staying toasty for the start of next week, but a few cities in the valley may fall back into the double digits on Monday afternoon.
