SAN ANTONIO – Cold air has been the focus of the weather forecast so far this week.

In fact, San Antonio saw its coldest temperature of 2019 on Thursday morning with a low of 27 degrees!

However, the forecast focus now shifts from temperatures to chances of rain.

A low pressure system will move across Texas beginning early Friday, moving out of the Lone Star State early Saturday. The intensity of this low pressure system won’t allow for a lot of widespread, heavy rain. Rather, a high coverage of very light, passing showers is expected across San Antonio and South Texas.

The weather will begin to change Thursday night. Skies will become overcast and it won’t be as cold. Low temperatures will only fall to the low 40s.

By rush hour Friday morning, mist and drizzle will be likely. Isolated showers will also be moving in from the southwest.

By midday, a higher coverage of rain is expected as showers continue to stream in.

Passing, light showers will stay in the forecast through the late-afternoon and early-evening hours. Additionally, the cloud cover and rain will limit temperatures to the low to mid-50s on Friday, so you’ll want to keep a jacket with you all day.

Bottom line: Friday will end up being a damp, cool day!

While it’s encouraging to see chances of rain in the forecast for such a big part of the day on Friday, this won’t end up being a drought-busting rainfall. Rather, most locations should expect no more than a quarter-inch of rain from Friday morning through Friday night. Exceptions to this and some of the locations that could see closer to a half-inch of rain through Friday night will be those well east of I-35 and south of I-10.

As the low pressure system that brings us the rain Friday moves out of Texas on Saturday, skies will clear and it will end up being a nice weekend.

Fog will be possible each morning this weekend.

Sneak Peek: Christmas Eve and Christmas Day next week are looking warm with highs in the low 70s.
