CORPUS CHRISTI, Texas — High pressure in the upper air will remain over Texas this coming week, preventing rainfall while generating extreme heat and trapping Gulf humidity resulting in life-threatening afternoon heat indices. Expect afternoon temperatures from the upper 90s to lower 100s, with 105 and 109 degrees expected inland. Overnight readings will linger in the upper 70s to lower 80s. Mid-level energy sliding across the Southern Plains will increase our onshore winds, with south southeasterly breezes gusting near 30 miles an hour at times. Heat index values will peak between 114 and 122 each afternoon. Accordingly, Excessive Heat Warnings and Heat Advisories will be needed generally between Noon and 9 pm daily. The strong winds will necessitate Small Craft Advisories the next few afternoons for the coastal waters, bays and inland waterways. Along with the extreme heating and strong winds, lower relative humidity values inland will mean elevated fire danger through the coming week.
There is a slight chance for showers next Monday, as a wave of instability moves across the Gulf of Mexico and through the Middle and Lower Texas coast. Rainfall distribution and totals will be modest, however.
The tropics remain generally quiet, for now. There is no significant activity in the Atlantic Basin, while in the Eastern Pacific Tropical Storm Eugene will soon become a post-tropical remnant low while passing over cooler sea surface temperatures. Category 4 Hurricane Dora now has moved into the Central Pacific Basin and will pass well south of Hawaii.
