San Antonio isn’t headed for a permanent cool-down just yet, but cold front after cold front has been providing some relief from summer-like temperatures this month. Here’s when one local TV meteorologist predicts the next one will sweep through the Alamo City.
News 4 San Antonio Chief Meteorologist Chris Suchan projected a dip in temperatures and a chance for scattered rain coming on Tuesday, October 27, and Wednesday, October 28. In an October 20 Facebook post, he wrote, “After getting a taste of fall weather with our last front, many questions on when we can expect our next front … At this time, not a strong front but one with a cooler change and also our next scattered rain chance.”
In the post, Suchan added an image from the Euro model, a computer weather forecasting system that can predict weather up to 15 days in advance. However, conditions can change quickly, and forecasts several days out don’t always unfold as predicted. A seven-day forecast Suchan posted on October 21 suggests a high of 76 degrees and a low of 64 degrees, with a 40% chance of rain.

As for when locals can expect things to finally cool down until next year, a lead meteorologist for the NWS Austin/San Antonio office recently told MySA that it will likely happen sometime in November and December…
