It's going to be another hot day across the Rio Grande Valley and the ranchlands, with temperatures easily surpassing the 100 degree mark for much of the area today, with only those areas east of US-77 seeing slightly cooler temperatures with highs in the mid to upper 90s. If you're going to be spending time outside, be sure to drink plenty of water and seek shade when possible. Mariners can expect seas of 2-4 feet on the Gulf, with a light chop increasing to a moderate chop on the bay due to increasing southeast to east winds this afternoon.
A low risk for rip currents is expected again today at the beaches of South Padre Island and at Boca Chica. Even though the rip current risk is low today, life threatening rip currents are still possible, especially in the vicinity of the South Padre Island Jetties. Afternoon temperatures will top out in the upper 80s and be accompanied by mostly sunny skies. With the UV index in the extreme range, it's recommended to use sunscreen and to re-apply often. Have a fun and safe day at the beach!
High pressure continues to keep the hot and dry pattern through the weekend. Isolated to scattered showers and thunderstorms possible across the coastal counties through the work week, primarily along the sea breeze, as moisture increases across the region. The heat continues, with Sunday being the hottest of the next five days. Slightly "cooler" temperatures are expected through the remainder of the work week, with afternoon temperatures ranging from the mid 90s to a few degrees above 100 each afternoon. Even higher heat indices or "feels like" temperatures are expected when humidity is factored in, reaching up to 110 degrees in many areas. Overnight lows will remain warm, ranging from the upper 70s into the low 80s.
