Before jumping into the forecast, let’s take a look at the latest drought monitor that was released Thursday. South Texas needs some rain!

Unfortunately, Friday evening’s storms will NOT be a drought buster. In fact, rainfall totals will likely be on the low end, but any rain is welcome at this point.

Now, let’s take a look at timing...

Through early Friday afternoon, don’t expect a lot to change. Skies will stay mostly cloudy and a few light showers will be possible.

By about 4 p.m., some isolated storms could be developing west of I-35.

Those storms are expected to approach San Antonio and the I-35 corridor around 5 p.m.

The best ‘window’ for storms to affect San Antonio and Bexar County will be roughly 5 p.m. to 8 p.m.

Futurecast - Valid 6:00 PM Friday, January 10, 2020

Storms will move east of the I-35 corridor and away from San Antonio by about 9 p.m. Friday.

As far as what the storms could produce, it is possible that some storms could become severe late Friday afternoon and Friday evening. The best chance of that happening will be along and east of I-35.

The main threats with any storms that become severe will be damaging thunderstorm winds and large hail.

Now, let’s look at potential rainfall totals. Again, this will not be a drought buster. San Antonio’s totals will only reach about a half of an inch on the high end. Larger totals will show up to our north and east.
