Ensembles are in decent agreement high pressure is expected to build westward into Northern California early next week as troughing continues off the Pacific Northwest. Temperatures will trend warmer with moderate heat risk across the Valley as well as warm overnight lows along thermal belts.

Heat Risk Next Week

Afternoon highs in the Northern Sacramento Valley could remain in the triple digits for much of next week peaking around mid-week with current forecast highs reaching 106 for some areas.

Maximum temperature loop - lots of very high temps!

Monsoonal showers and thunderstorms will be possible once again over the Sierra with chances extending northward mid to late week.

Models are also starting to show the potential for a small low pressure area developing off the Central Coast of California around mid-week. This potential area of low pressure could lead to passing clouds over the region and temperatures trending lower towards next weekend.
