This comprehensive weather update covers the expected temperature ranges, potential precipitation, and other meteorological factors that will shape San Antonio’s climate on this December day.
Current Weather Overview
On December 4th, San Antonio is experiencing mild to cool conditions typical of early December. Morning temperatures began in the low 50s °F (10–12°C), with highs expected to reach the mid-60s °F (18–20°C) during the afternoon. While the day will be relatively pleasant compared to colder regions of the U.S., residents should be prepared for fluctuating weather throughout the day, particularly as early mornings and evenings bring cooler temperatures.
Temperature Trends and Daily Highs
The weather forecast indicates a gradual warming trend, with daytime temperatures hovering around 65°F (18°C), and evening temperatures dipping to the low 50s °F (10–12°C). This temperature range is characteristic of December in central Texas, where warm days are often followed by cool nights.
- Morning lows: Low 50s °F (10–12°C)
- Daytime highs: Mid 60s °F (18–20°C)
- Evening temperatures: Low 50s °F (10–12°C)
Despite these mild conditions, it’s important to note that San Antonio’s weather can quickly shift, especially with cold fronts moving in from the north. Therefore, it’s advisable to bring a light jacket or sweater if you’re heading outdoors during the evening or early morning hours.
Precipitation Forecast and Rain Chances
One of the more notable aspects of today’s forecast is the potential for isolated showers later in the day. While rainfall is not expected to be widespread, there is a chance of light, scattered rain showers in the late afternoon or evening. This could affect commute times and outdoor plans, so residents should keep an eye on the sky for sudden changes.
Rain Possibility and Timing
According to the latest updates from the National Weather Service, the likelihood of rain increases as the afternoon progresses. The expected rain will be light and sporadic, with accumulations of less than a quarter inch in most areas. Areas closer to the Hill Country or more elevated terrains may experience slightly more rainfall due to orographic lift.
- Rain chances: 20–30% in the late afternoon and evening
- Expected rainfall: Less than 0.25 inches in most areas
If you plan to be outside after 3:00 PM, consider carrying an umbrella or wearing weather-appropriate gear in case of a brief shower. However, it’s unlikely to be heavy enough to cause significant disruptions to daily activities.
Wind and Humidity Conditions
Wind conditions will be moderate throughout the day, with sustained winds of 5 to 15 mph, occasionally gusting up to 20 mph in the late afternoon. These winds will add a slight chill to the air, especially during the evening hours, so it’s advisable to dress in layers to stay comfortable.
Humidity will remain relatively high, typical of San Antonio’s winter months, hovering around 80% in the morning and tapering off to 60% by the evening. This humidity level can make the air feel cooler, particularly when combined with the wind, so expect the temperatures to feel somewhat lower than they actually are, especially after sundown.
Extended Forecast for San Antonio
The weather outlook for the coming days includes more variability as the city moves through the first week of December. According to forecasts from the National Weather Service, San Antonio will see a cooler front moving in later this week, bringing the potential for slightly lower temperatures and more consistent rain showers. December 5th is expected to be a bit cooler, with daytime highs in the low 60s °F (16–17°C) and a greater chance of rainfall.
Key Points for the Next Few Days
- December 5th: Temperatures in the low 60s °F (16–17°C), with increased chances of rain.
- December 6th-7th: Cooler temperatures, ranging from the mid-50s °F (12–14°C) during the day to low 40s °F (5–6°C) at night, with higher rain chances.
- Long-term forecast: Mild conditions are expected to return by the weekend, with temperatures rising into the mid-60s °F (18–20°C).
For residents, these temperature swings and periodic rain can make it difficult to plan outdoor activities without staying informed about the weather. It’s crucial to keep an eye on both short-term updates and longer-range forecasts to adjust plans accordingly.
Implications for Commuters and Outdoor Plans
The expected weather on December 4th will likely impact commuters, particularly during the afternoon and evening hours when light rain showers could create slick road conditions. Drivers should exercise caution and reduce speed, especially on bridges and overpasses where rain tends to accumulate more quickly.
If you’re planning any outdoor events or activities, keep in mind that while temperatures will be moderate, there’s always the possibility of quick, unpredictable changes in the weather. Those planning holiday shopping, outdoor exercise, or family outings should be prepared for light rain and a cooling breeze in the late afternoon.
Safety Tips for Rainy Weather
- Carry an umbrella: Even if rain is only expected to be light, it’s always a good idea to have an umbrella on hand.
- Dress in layers: Wind and rain can make the temperature feel colder than it is, so dress in layers that can be easily adjusted.
- Watch for slick roads: Rain increases the risk of hydroplaning, so make sure your tires are properly inflated and your brakes are in good condition.
Conclusion
San Antonio’s weather on December 4th presents a classic snapshot of early winter in Texas, with mild daytime temperatures and a slight chance of afternoon rain. While conditions will be manageable for most, it’s important for residents to stay informed of changing conditions, especially with light rain and moderate winds expected later in the day. Whether you’re commuting or planning an outdoor activity, a little preparation can go a long way in making sure you’re comfortable despite the shifting weather.
