Cool temperatures and chances of rain by Friday evening

A cold front was the talk of the town this week, providing colder temperatures, rain and occasional storms across South Texas. However, the front did not actually advance all the way through San Antonio. Instead, it stalled just to the north, maintaining highs in the 90s while areas to the north were noticeably cooler.

The front is finally expected to fully push through San Antonio by Friday night, likely bringing cooler temperatures and a moderate chance of thunderstorms to the area.

Schedule for Friday

After a comfortable start with temperatures in the mid 70s, our temperatures will quickly warm into the low 90s by the afternoon. High humidity levels will bring the temperature closer to 100 degrees between 1 p.m. and 3 p.m

Then things get more interesting as the cold front moves through South Texas. Temperatures will begin to drop slightly in the late afternoon and will drop faster as the evening approaches. Temperatures may drop into the 70s by 9 p.m. in San Antonio as the cold front finally receives some fall-like air.

The front will bring a chance of thunderstorms to the area this evening. The chances in San Antonio are 50 percent.

Axial weather

Thunderstorms will be accompanied by low temperatures. After a dry first half of the day, thunderstorms will increase in coverage along the cold front Friday afternoon and continue into Friday night. Rain chances will generally be very high, as high as 50 percent in San Antonio. Some storms could bring hail and damaging wind gusts, but widespread severe weather is not expected.

Scattered rain and storm chances continue on Saturday. Between Friday and Saturday, rainfall totals are expected to range between 0.50 to 1.00 inches with locally higher amounts. Flooding will be possible in areas with the highest rainfall, but widespread flooding is not expected.

Weekend forecast

Cold air will continue to flow in from the north as we head into the weekend. No, it won’t be “cold” outside yet, but high temperatures will be comfortably in the upper 80s to low 90s across much of South Texas. The average high temperature for Saturday is 90 degrees, so we’ll be pretty close to that.

There will be scattered chances on Saturday of 30 to 40 percent. However, these chances will decrease significantly on Sunday, as more sunshine is expected to appear by the second half of the day.

Forecast for next week

For the most part, we will return to a calmer weather pattern next week. Temperatures will rise a few degrees, reaching the high 90s on Monday and then reaching the mid 90s by midweek. These temperatures will be above average in the second half of September, but at least the triple digits should stay away.

There will be some minor rain chances during the week, but so far none of those chances appear to be above 20 percent. This is due to weak high pressure moving back over southern Texas, heading from northern Mexico.
