Expect a mix of sun and clouds today across deep south Texas as temperatures rise this afternoon to above the century mark west of US highway 77 while areas to the east of the highway hover in the 90s. Heat indices or “"feels like"” temperatures are expected to reach between 105 and 110 degrees Fahrenheit. For the mariners, expect east to southeast breezes with a light chop building to a moderate chop across the bay and seas of 1-3 feet over the coastal gulf waters.
A low risk for rip currents is expected today along 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. Another hot day expected with partly cloudy skies and afternoon temperatures up to near 90 degrees Fahrenheit. With the UV index in the extreme range, it is recommended to use and re-apply sunscreen often. Have a fun and safe day at the beach!
Isolated showers and thunderstorms will be expected over the coastal counties through the early and middle half of the workweek, primarily along the sea breeze. Friday will feature a slightly better chance for rain and thunderstorms across the entirety of deep south Texas with the arrival of additional gulf moisture from a tropical wave in association with the remnants of Tropical Storm Harvey. Temperatures stay around normal this upcoming workweek with afternoon highs ranging from the middle 90s to above the century mark out west. With humidity factored in, expect heat indices or 'feels like' temperatures between 104 and 108 degrees for each afternoon. Overnight lows are to range from the middle 70s to near 80 degrees each night.
