Fresno is waking up Thursday, November 5, with morning fog lifting, skies clearing and temperatures rising to near 69 degrees later in the day. A Dense Fog Advisory is in effect across the San Joaquin Valley until 10 a.m. Thursday, with visibility potentially dropping to a quarter-mile or less. Drivers should slow down, use headlights and leave extra distance when visibility is low. The National Weather Service says dense fog may form Thursday night into Friday morning and forecasts a high near 69; its advisory runs until 10 a.m. Thursday.
Morning Fog Could Affect Plans
Fog can affect visibility and complicate errands, school drop-offs and afternoon plans.
The advisory reaches beyond Fresno to major Valley routes: the National Weather Service lists Interstate 5, Highway 99 and state routes including 41, 99, 168 and 180 among the roads where low visibility could make driving hazardous. The warning calls for slower speeds, headlights and extra following distance while the fog persists. The National Weather Service advisory remains in effect until 10 a.m. Thursday.
Sunny Stretch Builds Into Weekend Warmup
Friday should reach about 71 degrees under sunny skies, followed by an even warmer Saturday near 76 and Sunday near 75. Overnight lows will remain cool, generally in the upper 40s to low 50s, making mornings jacket weather even as afternoons turn comfortable.
Dry Outlook Brings A Brief Early-Week Cooldown
Dry weather and cooling are expected early next week, with no rain expected through Tuesday. Veterans Day falls on Wednesday, November 11.
Wood-Burning Restrictions Remain In Place
Fresno County's Thursday, November 5, 2026, fireplace and wood-stove status is listed as “No Burning Unless Registered.” Residents should check that guidance before lighting a fireplace or stove, particularly while the valley is dealing with stagnant morning conditions and fog.
The wood-burning limits are part of the Valley Air District’s winter effort to curb particulate pollution: its Rule 4901 season runs from Nov. 1 through the end of February and covers indoor and outdoor residential devices burning wood, pellets or manufactured logs. “No Burning Unless Registered” means residents may use a registered clean-burning device indoors, but unregistered wood-burning devices are prohibited. The district’s Rule 4901 guidance also lists exceptions, including homes without natural-gas service or where wood is the only heat source.
