FORECAST:

Good morning! It appears as though the hottest day of the year is underway. Temperatures are forecast to soar to 106° in San Antonio, while heat index values will make it feel as though it’s 108-111°. This is dangerous heat and excessive heat warnings remain in effect. When it comes to after school activities, here’s how the UIL decides what’s safe and what’s not.

During peak heating late this afternoon, it’s possible a stray storm could develop. Anything that pops up would be short-lived and likely won’t output much rainfall. Gusty winds and lightning, however, are possible. The odds of rain are low, but we’ll certainly keep watch on the radar later today.

After today, temperatures start to decline. Triple digits are still in the forecast for Thursday and Friday, but it won’t be as hot as today. By the weekend and next week, more clouds and a weakened heat high will allow temps to fall into the mid-90s. An area of low pressure will also give us some isolated, afternoon showers early next week.
