This weekend will start a lot like how the past couple of weeks have gone: South Texas temperatures will be significantly above average, and rain chances will be almost nonexistent .
Changes are coming, though, after Saturday. Gulf moisture will be increasing Sunday, and when a weak cold front slides into the region by Sunday night, it could actually help spark a few thunderstorms across parts of Central, South, and East Texas. Here’s what you can expect.
Today’s forecast
Thanks to southerly winds across the area, morning temperatures will be more mild today than they were Thursday and Friday. San Antonio temps will hover in the mid-50s between 5 and 8 a.m ., rising steadily after sunrise. Temps will already be in the upper 70s by noon.
San Antonio daytime temps will top out in the mid- to upper 80s, likely around 87 degrees. Mostly sunny skies are expected to continue, and no rain chances are expected across the entire state. Winds will be breezy, coming in from the south at 15 mph with some gusts up to 25 mph.
Sunday’s forecast
Atmospheric moisture from the Gulf of Mexico will continue to stream into the area Sunday, resulting in more clouds for South Texas. Temperatures will fall short of the previous day’s high by a couple of degrees, but San Antonio will stay warm, topping out in the mid-80s.
Storm chances: The more interesting weather arrives by Sunday night, as a weak cold front approaches from the north. This front will not bring a significant drop in temperatures, but as it interacts with the moisture-rich air over Texas, scattered thunderstorms will form.
The atmosphere will be unstable, so any storm that develops could become strong to severe, capable of large hail and damaging wind gusts…
