Dallas is starting today under clear skies, but the reprieve will be brief. Temperatures are expected to climb to about 102 degrees, with heat index values reaching as high as 106 while south to southeast winds stay mostly between 5 and 10 mph.
A Heat Advisory remains in effect across Dallas and much of North Texas until 8 p.m. today. The National Weather Service says heat index values could reach 108, increasing the risk of heat-related illness for people working or spending extended time outside.
Small Storm Chance East Of I-35
Most of Dallas should remain dry, but isolated showers and thunderstorms could develop late Tuesday afternoon and evening, mainly east of the I-35 and I-35E corridors. Severe weather is not expected, though any storm that forms could bring lightning, gusty winds, and a brief burst of heavy rain, according to the National Weather Service Fort Worth/Dallas.
The latest update keeps the heat threat firmly in place after an earlier Hoodline forecast flagged the weeklong stretch of extreme temperatures. Tuesday's advisory and the continued run of triple-digit highs make this a more urgent day for outdoor plans than the previous outlook suggested, as noted in Hoodline.
Triple-Digit Heat Holds Through Saturday
Tomorrow will bring another sunny day with a high near 101 and a heat index around 104. Highs should remain near 100 on Thursday, Friday and Saturday, with only a slight dip to 99 next Sunday and 97 next Monday.
Overnight relief will be limited, with lows around 81 tonight, 80 tomorrow night and about 79 from Thursday through Saturday. The low is forecast to dip to roughly 77 next Sunday night before next Monday's modest cool-down.
Outdoor Plans Need Extra Precautions
People heading outside should drink plenty of water, wear lightweight clothing, and schedule strenuous activity for early morning or evening. The National Weather Service also urges residents to take frequent breaks in shade or air conditioning, check on neighbors and relatives, and never leave children or pets in an enclosed vehicle.
Clear skies will dominate much of the week, but the heat will not let up quickly. With temperatures hovering around 100 degrees for several more days, even short outdoor errands could feel more demanding than usual.
