Temperature Outlook: A Moderately Cool December Day
For most of Thursday, San Antonio will see relatively moderate temperatures, characteristic of its typical winter season. According to the latest forecasts, the daytime high is expected to reach around 68°F (20°C), with temperatures in the morning hovering around the low 50s°F (around 10°C). These temperatures are fairly typical for mid-December, reflecting a slight cooling trend after the region’s warmer November temperatures.
As the day progresses, temperatures will gradually climb towards the afternoon high. However, a cool breeze could make the air feel slightly chillier than the thermometer reads, particularly for those spending extended periods outside. By evening, temperatures will dip back into the low 50s°F, with a potential drop into the mid-40s°F after sunset.
Factors Influencing Temperature
- High Pressure System: A dominant high-pressure system over the state is keeping temperatures in check, preventing extreme fluctuations and promoting relatively stable conditions.
- Wind Patterns: Winds from the north will contribute to a mild, dry air mass, helping to prevent any substantial warmth from accumulating.
- Cloud Cover: While there may be intermittent cloud cover during the day, it’s unlikely to block out much of the sun, contributing to relatively mild warmth.
Rain Forecast: A Possibility of Light Showers
One of the key factors to consider for San Antonio’s weather on Thursday is the chance of rain. While it’s not expected to be a major storm day, the possibility of light rain or scattered showers exists throughout the day, particularly during the late morning to afternoon hours. The National Weather Service has issued a general weather advisory for the area, noting a 30% chance of precipitation.
The rain, if it materializes, is expected to be light and sporadic, with the heaviest showers likely to occur closer to the early afternoon. For most residents, any rainfall is expected to be brief, amounting to less than half an inch, though localized heavier downpours cannot be ruled out in certain areas. The rain is expected to taper off by the evening, with skies clearing overnight.
Impact of Rain on Daily Activities
- Traffic: Light rain showers could create slick roads, especially for those commuting during the late morning and early afternoon. Drivers should be cautious and allow extra time for their trips.
- Outdoor Events: For those planning outdoor activities or gatherings, it’s advisable to check weather updates and have a backup plan in case of rain.
- Gardens and Agriculture: A brief period of rain could provide a much-needed drink for local gardens and crops, although the light showers are unlikely to have a significant long-term impact.
Wind and Humidity: Mild, Dry Conditions
Along with the moderate temperatures, Thursday will also bring mild winds and dry air to San Antonio. Winds are expected to be light to moderate, generally between 5 to 10 mph, though gusts could reach up to 15 mph during periods of cloud cover or rain showers. These breezes will come from the north-northeast, which will help to keep humidity levels low.
Humidity will remain fairly low throughout the day, with levels between 30% to 40%, making for a comfortable outdoor experience. While this means the air will feel dry, it also reduces the chances of widespread fog or dew, ensuring clear visibility and minimal disruption to outdoor plans.
Wind’s Effect on the Region
- Air Quality: The dry air combined with moderate winds will help disperse pollutants, keeping air quality levels relatively good. For those with respiratory issues, the low humidity may reduce the discomfort often associated with more humid conditions.
- Outdoor Sports: Light winds will have little impact on outdoor sporting events, making conditions favorable for activities like soccer, football, and jogging.
