The summer heat will remain in full force across deep south Texas today with temperatures in the 90s along the coast and above the century mark further inland. It will feel even hotter though, as the heat and low level moisture combine to produce heat index or “"feels like"” values of 105 to 110 degrees today. The winds will be breezy into and through the afternoon today from the southeast direction. For the mariners, expect winds of 10 to 20 knots with the Laguna Madre becoming choppy and gulf seas of 3 to 6 feet, occasionally higher. Small Craft Advisory for Winds are in effect for the Laguna Madre and the nearshore gulf waters from 0 to 20 nautical miles from 1 pm until 8 pm. Small craft should exercise caution on the offshore gulf waters from 20 to 60 nautical miles out.
A moderate risk for rip currents will be expected today along the beaches of South Padre Island and at Boca Chica Beach as a result of elevated wind driven waves. Remember to swim near a lifeguard or use a non-inflatable flotation device, such as a life jacket or boogie board. Expect hot conditions with temperatures near 90 degrees, partly cloudy skies and breezy conditions with southerly winds of 20 to 25 mph. UV index remains extreme today, so be sure to grab the sunblock before heading out for the day.
Hot conditions with a mix of sun and clouds will be the mainstay in the forecast this week across the valley and the rest of deep south Texas. Heat indices or “"feels like"” temperatures of 105 to 110 degrees will be possible each afternoon through Friday. Isolated showers and thunderstorms are expected Tuesday through Thursday with an area of low pressure and increasing moisture from the Gulf. Overnight lows remain near or slightly above normal into next week in the mid and upper 70s to near 80.
