TEXAS — A fast-moving cold front is set to sweep across South and Central Texas, reaching San Antonio within the next 3 to 4 hours, bringing strong wind gusts between 30 and 40+ mph, a noticeable drop in temperatures, and conditions favorable for a spike in Mountain Cedar pollen through the weekend. Weather data shows the strongest winds developing behind the front, with gusts spreading southward from West Texas into the Hill Country and South Texas by late evening.
Timing: When the Cold Front Reaches San Antonio
According to the forecast data, the cold front is expected to arrive in San Antonio later this evening, with peak wind gusts occurring shortly after passage. By around 10 PM, much of South Texas will already be experiencing post-frontal conditions, including cooler air and strengthening northerly winds.
Wind Gusts Expected to Reach 30–40+ MPH
The wind gust map clearly shows a corridor of 30–40 mph gusts, with some localized areas briefly exceeding that range, especially across:
- West Texas
- The Texas Hill Country
- Areas southwest of San Antonio
These winds are strong enough to make driving difficult for high-profile vehicles, blow around unsecured outdoor items, and create reduced visibility in dusty or rural areas.
Cooler, Drier Air Moves in Behind the Front
One of the most noticeable changes after frontal passage will be the sharp drop in humidity. Behind the front, Texas will shift from warmer, humid air to much cooler and drier conditions, making the air feel significantly different even if temperatures don’t plunge immediately. This type of air mass is typical of strong winter cold fronts moving south through the state.
Why Mountain Cedar Pollen Levels May Spike
The forecast also highlights an important secondary impact: Mountain Cedar pollen. Strong northerly and northwesterly winds are expected to transport large amounts of cedar pollen from the Hill Country into South and Central Texas, especially between Saturday and Monday.
Mountain Cedar (also known as Ashe Juniper) releases pollen most aggressively during dry, windy conditions — exactly what this pattern creates.
Who May Be Most Affected
Residents most likely to notice impacts include:
- Allergy sufferers sensitive to cedar pollen
- People with asthma or respiratory conditions
- Outdoor workers and commuters
- Drivers of trucks, vans, and RVs
Even those without allergies may experience irritated eyes, scratchy throats, or sinus pressure due to the dry, gusty air.
What to Expect Over the Next 48 Hours
Over the next two days, Texas will remain under the influence of this cooler, drier air mass. While no severe storms are indicated, gusty winds and elevated pollen levels remain the primary concerns. Temperatures will stay cooler than recent days, with humidity remaining low.
A strong winter cold front is set to move through San Antonio and surrounding parts of Texas, delivering 30–40+ mph wind gusts, cooler and drier air, and a likely spike in Mountain Cedar pollen levels through the weekend. While not dangerous, the combination may be uncomfortable for many residents and disruptive for outdoor activities.
