Sacramento is starting Thursday clear and near 50 degrees, but the city is headed for a fast warm-up and an 87-degree afternoon. Skies stay sunny, rain stays away through the weekend, and the bigger concern is dry air and gusty winds developing around the region. The weather will feel more like late summer than mid-October, at least for a few more days.

Sunny Thursday Brings A Sharp Afternoon Warm-Up

Temperatures should climb from the low 50s early Thursday to the upper 80s by late afternoon, with light north-northwest winds around Sacramento. Friday will be dry, with Valley highs in the 80s, followed by lows in the mid-50s Friday night.

Fire Weather Concern Builds Outside The City

The National Weather Service Sacramento office has a Red Flag Warning in effect from midnight Thursday through 10 a.m. Friday for the Sierra and adjacent foothills. Parts of the Sacramento Valley along and west of Interstate 5 could also see gusts of 25 to 35 mph, while afternoon humidity falls into the low 20s; downtown Sacramento's official forecast calls for lighter winds.

That combination means any fire that starts can spread quickly, so residents should be cautious with outdoor flames, hot equipment and sparks near dry grass or brush. The new warning is the meaningful change from Hoodline's earlier Sacramento forecast, which outlined the warm-up but noted no active watches or warnings in the city.

Cooler, Slightly Unsettled Pattern Arrives Next Week

Saturday stays sunny and warm near 87, then Sunday is expected to cool to near 80. Monday is expected to cool further, with a high near 71. Renewed precipitation is possible early to mid next week as a cooler pattern moves in.
