August 1, 2020 – Dry and seasonably hot conditions are expected to continue across the region into the weekend. Cooling returns next week.
Discussion
Northern California will remain situated between an upper level low sitting off the coast and the Four Corners high pressure through the weekend. This will keep daytime temperatures warm and up to 5 degrees above normal with upper 90s to 103 in the Valley and 70s to 90s in the mountains and foothills. A moderate Delta Breeze will keep morning lows mild.
Ensembles then bring the upper trough through NorCal early next week. Onshore flow will increase with this, especially in Delta influenced areas. Temperatures will begin to cool a bit to near or slightly below normal by Tuesday. However, dry conditions are expected to continue at least through midweek.
Extended Discussion (Wednesday through Saturday)
Ensembles indicate weak upper trough lingering along the West Coast later next week.
The result is expected to be a continuation of dry weather with temperatures a little below average for early August.
