South Central Texas is expecting a decent Fall cold front by Wednesday afternoon. While it might not be chilly, we will see cooler temperatures and some rain after the front moves through. Look for the boundary to arrive Wednesday afternoon.

In the meantime, Tuesday should feature ample sunshine and one last day of hot weather for the region. With mostly sunny skies, we’ll see most spots top out in the low 90s Tuesday afternoon. A few isolated showers might pop up in the heat of the day, but most rain should stay east of the I-35 corridor.

Overnight, clouds and moisture surge northward in advance of the front. Some sprinkles are possible into the daybreak hours Wednesday and then showers and a few thunderstorms as the front arrives in the late afternoon. We’ll look for a few brief heavy showers but the system should be moving fast enough to keep flooding issues to a minimum.

Cooler air follows the front but then an overrunning pattern sets up for a few cooler, rainy days to finish the week.

It has already been the wettest September in San Antonio history; an inch or more with the next front will put September 2018 as the number one wettest month of all time in San Antonio.
