Residents across Central and South-Central Texas are waking up to patchy and dense fog this morning, with visibility dropping below a quarter mile in some western and southwestern counties. A Dense Fog Advisory remains in effect for portions of the Coastal Plains and areas south and southwest of the San Antonio metro until 9 AM. Drivers are advised to use low-beam headlights, maintain safe following distances, and allow extra time for travel due to rapidly changing visibility.

While fog is more scattered outside the advisory zones, sudden drops in visibility remain possible. Patchy fog is expected to redevelop overnight into Monday morning, with visibility occasionally falling to one mile or less.

As the fog and low clouds clear, skies will transition to partly cloudy and eventually sunny conditions by afternoon. High temperatures today will range from the mid-70s to mid-90s, running 5 to 10 degrees above seasonal averages.

Looking ahead, a strong cold front is forecast to move through the region on Tuesday, bringing a noticeable shift in weather. Rain chances will increase across portions of North and Central Texas, followed by much cooler temperatures and gusty northwest winds. Overnight lows Tuesday into Wednesday are expected to dip into the 40s, marking the coolest readings since April.

Wind gusts behind the front may reach 35 to 45 mph, with sustained winds between 20 and 30 mph. Residents are encouraged to secure lightweight outdoor items—including Halloween decorations—before the front arrives. High-profile vehicles should exercise caution on roadways due to strong crosswinds.

The cooler air will settle across South-Central Texas midweek, with below-average temperatures likely through Thursday and Friday. Afternoon highs will remain pleasant in the 70s, and dry conditions are expected to persist through the week. Temperatures will begin to rebound over the weekend.

Fire weather concerns may increase on Wednesday due to breezy conditions and dry air, so residents should stay informed about local advisories.
