Friday, August 20, 2010
August is my least favorite month for weather in San Antonio, but one of the good things about the searingly hot month is that the last week is normally the beginning of a slow, but real transition into Fall. As most of you know, our definition of Fall is different than up north. For San Antonio, Fall usually means less intense heat and increasing chances for moisture. The first signs of that change should arrive during the middle of this week, when we may see our first "not so hot" front dive far enough south to break down the "Hell High", giving us a good chance of rain for several days. If the Hell High abates, look for a more tropical pattern, similar to what we were experiencing during the first half of the summer. That will not only lower our temperatures, but increase the chances of seeing some tropical systems in the Gulf. Hopefully those systems will stay weak and not cause any major damage, but with the Atlantic and Gulf water temperatures running above normal, the chances of several major hurricanes forming in September look very good.
