I was surprised to see the weekend weather on the news. This is because a significant temperature swing is forecasted for San Antonio.

During the day, it will feel almost like summer, while at night it will get chilly again, showcasing typical March weather this weekend.

First, looking at today's Thursday weather, the high is about 69 degrees, and the low is 44 degrees. In the morning, there will be a slight breeze, making it feel cooler than usual. At night, the sky will clear up, and temperatures are expected to drop significantly, leading to a chilly night. You can expect to dress lightly during the day and then suddenly feel cold at night.

Starting Friday, the atmosphere changes a bit. The daytime temperature on Friday will rise to about 80 degrees. With strong sunlight and clear skies, it will likely feel quite warm. It might even feel like early summer during the day. However, at night, temperatures will drop back down to around 50 degrees. This is a typical Texas pattern where the perceived temperature changes significantly within a day.

Saturday is even more dramatic. The high temperature will reach 84 degrees. It will be warm enough to wear short sleeves. The sky will generally be clear, and with strong sunlight, the perceived temperature may feel even higher. However, at night, it will drop to around 64 degrees. The difference between day and night continues to widen.

The problem arises on Sunday. The daytime temperature is forecasted to soar to a whopping 87 degrees or even higher.

This can almost be considered summer weather. However, at night, temperatures may drop below 40 degrees. This means a temperature difference of over 40 degrees in a single day. Such weather can be hard for the body to adjust to.

After that, there will still be some difference between the high and low temperatures. At night, it will drop to around 41 degrees, leading to chilly days again.

The key point of this weekend's weather in San Antonio is the extreme temperature fluctuations.

During the day, it will be warm enough to wear short sleeves, while at night, temperatures will drop to a level where a light jacket is needed. Especially on Sunday night, there is a possibility of strong winds, which could make it feel even colder.

Such weather can easily lead to colds or body aches. This is because many people tend to dress lightly during the day when it's warm and then suddenly feel cold at night. It would be wise to pay attention to your clothing choices when going out this weekend, as the temperature difference between day and night is quite significant.
