San Jose is waking to clear skies and temperatures around 57 degrees Friday morning, but the easy start will not last: afternoon heat is headed toward 91 degrees. Saturday stays sunny and warm near 90 before a sharp cooldown brings more typical fall temperatures to the South Bay on Sunday.
Friday Heat Peaks Under Clear Skies
The National Weather Service in San Francisco expects Friday's temperatures to reach their highest levels during the midafternoon, with readings around 90 degrees. Winds should stay light for much of the day before a northwest breeze reaches roughly 6 mph late in the afternoon.
Dry Conditions Raise Fire-Weather Concerns
A Fire Weather Watch covers the North Bay Interior Mountains, while higher elevations around the Bay Area remain unusually dry through Friday. Anyone using outdoor flames should be especially careful in dry areas.
Weekend Cooldown Arrives Fast
Saturday is expected to be sunny, with a high near 88. Sunday drops to about 79, followed by a mostly sunny Monday near 69 as cooler air and the marine layer return to the region.
Rain Chances Build Next Week
Rain chances increase Tuesday and continue through late week. Hoodline's earlier forecast put Friday closer to 89 degrees, with rain chances increasing Tuesday and continuing through late week.
