As Houston basks under the sun with temperatures projected to hit a scorching 94 degrees today, residents are urged to prepare for a heat index soaring as high as 106. The tranquil morning breeze is expected to shift to the east, blowing at around 5 mph by the afternoon, according to the National Weather Service. The swelter continues into the night with a low of around 76 and light southeastern winds.
Tonight promises a clear sky, consistent with the mostly sunny streak slated for the weekend. Houston residents can anticipate climbing heat index values up to 102 on Saturday. Light winds will be taking a turn from the east to southeast at about 5 to 10 mph in the afternoon. The pattern of sultry nights and high-90s during the daylight hours will persist through Sunday, followed by a chance of showers and thunderstorms come Monday, hovering around 30 percent.
Even as the city contends with this heat, the National Weather Service Storm Prediction Center has outlined a marginal risk for severe thunderstorms extending over parts from Southwest Lower Michigan into Southeast Missouri. In their outlook, isolated strong to severe thunderstorms are forecasted during the late afternoon over parts of Illinois, Indiana, and southwest Lower Michigan, as well as across portions of the south-central Plains. A weak and receding boundary extending from Lake Michigan into central Illinois could stir up scattered thunderstorms, with the potential for locally strong gusts, according to the discussion at NWS Storm Prediction Center.
Back in Houston, the Heat Index Outlook warns of triple-digit temperatures this afternoon, a direct consequence of intensely high humidity levels and soaring mercury. Sunday and Monday, while still sizzling, leverage a slight respite with expected highs around 91. Moreover, the week unfolds with continued mostly sunny skies and persistently sticky evenings with lows hovering around 76, promising little relief from the relentless grip of Texas heat.
Today is shaping up to be another hot and humid day, with afternoon temperatures rising into the low 90s along the coast and the mid to upper 90s elsewhere. Heat indices this afternoon will rise into the triple digits across the area. #HOUwx #TXwx pic.twitter.com/kpoc7RfAy3
