FORECAST
It appears we are starting to settle into our typical summer regime. Minus a few passing showers over the weekend, there’s not much to the forecast this week.
SEASONABLE
The average high temperature is 93° and we’ll be within a degree or two of that over the next seven to ten days. However heat index values will reach 100 or higher for a few hours each afternoon.
ANY MORE RAIN CHANCES?
The summer heat high will prevent any rain chance over the next few days. It’ll shift east by the weekend, which will give us a chance for some passing showers. Rain chances will remain on the low-end. Also, with the “heat high” over the eastern U.S., cities as far north as Detroit and Minneapolis will be warmer than San Antonio.
