FORECAST:
It feels odd saying this after the last two blazing hot summers, but we’re headed into another stretch of “cooler” and potentially wetter weather. It won’t happen today, with hot and humid weather on tap for this afternoon. Highs will approach 100°, while heat index values will eclipse the triple digit mark.
The changes will begin to take shape late tomorrow. The heat high shifts farther east over the western half of the country setting us up for upper flow to be out of the north. Often, this can bring disturbances, weak fronts, and outflow boundaries down into South Texas. So is the case on Thursday, with a chance of isolated showers and storms by the afternoon. Right now, rain chances sit at 30%.
Beyond Thursday, small rain chances remain on Friday and Saturday. Sunday into next week looks a bit more active, with slighter higher odds for rainfall and below average temperatures. Have a great day! — Justin
