South Texas can expect more humid mornings and unusually hot afternoons<\/a> for the next several days, according to the National Weather Service. Although the hope for milder temperatures and a shot at some rain emerges later this week, don’t count on any\u00a0major shifts in the weather pattern<\/a> just yet. Here’s what forecasters say we can expect:<\/p>\n

Tuesday forecast<\/p>\n

San Antonio on Tuesday is shaping up to be mostly cloudy through mid-morning before skies gradually clear. Brace for another day of triple-digit heat with temperatures hitting 100 degrees<\/a> while humidity makes that heat feel more like 106. South-southeast winds of 5 to 10 mph, including gusts as strong as as 20 mph, will continue to deliver moisture-rich air into South Texas, forecasters said<\/a>.<\/p>\n

In the evening, under mostly clear skies, temperatures overnight through dawn Wednesday will bottom out around 76, as gusty southeast winds persist.<\/p>\n

An upper-level ridge of high atmospheric pressure continues to exert heavy influence on Texas weather, despite a shift toward to southeastern United States. The weather service had issued a heat advisory Monday for Texas counties along and east of Interstate 35, warning the public from San\u00a0Antonio to Houston of a higher risk for heat-related illnesses because of excessive humidity and extreme heat<\/a>.<\/p>\n

“Heat index values will be elevated (Tuesday) with\u00a0additional heat advisories potentially being issued again for\u00a0areas along and east of the I-35 corridor,” the weather service said in a forecast bulletin posted Monday<\/a>.<\/p>\n

\"Humidity-driven<\/p>\n

Wednesday forecast and beyond<\/p>\n

San Antonio on Wednesday should be mostly sunny, with afternoon temperatures staying in the double digits but peaking as high as 98 degrees, forecasters said. Southeast winds at 5 to 10 mph will help sustain humidity levels, so nighttime skies could become cloudier. Meanwhile, temperatures overnight should stay above 77 degrees.<\/p>\n

“The upper-level ridge dominates the local area weather promoting hot and humid conditions,” the weather service said. “(An) additional heat advisory may be needed for Wednesday, Thursday, and even Friday.”<\/p>\n

Although Thursday in San Antonio comes with a 30% chance of afternoon rain, skies will remain partly sunny. We could see daytime temperatures top out at 95. That’s\u00a0still a few degrees hotter than normal for mid-September, but closer to average than we’ve been lately. Gusty winds will shift to become more easterly as Thursday night skies become overcast. Overnight temps will likely stay above 75 degrees.<\/p>\n

Meanwhile, Friday has a 20% rain chance in the morning before skies turn mostly sunny. Temperatures should max out in the mid-90s, according to forecasters, accompanied by east-southeast winds.<\/p>\n

“Any shower or thunderstorm activity should be across the Coastal Plains,” the weather service said. “For\u00a0next weekend, an upper-level disturbance moving westward across\u00a0the Gulf states and an upper-level disturbance coming down across\u00a0the Southern Plains could bring beneficial rains for some parts of\u00a0South-Central Texas.”<\/p>\n
