Dallas is starting Thursday clear and around 82 degrees, but the city is headed for a punishing afternoon. Temperatures will climb to about 102 degrees, with the heat index reaching as high as 106.

A Heat Advisory is in effect through 8 p.m. today for Dallas and much of North Texas, according to the National Weather Service. South winds of 10 to 15 mph, with gusts up to 25 mph, will add to the afternoon discomfort, while dry conditions raise the risk of grass fires.

Triple-Digit Heat Keeps Its Grip

Tonight will stay clear, with a low near 79 degrees, but the heat index could still reach 104 before temperatures ease. Tomorrow will bring another sunny day near 101 degrees, followed by another warm night around 81.

The pattern is not letting up this weekend. Saturday and next Sunday should both reach about 102 degrees, next Monday could hit 104, and highs near 103 are expected next Tuesday and next Wednesday.

Little Rain And Limited Relief Ahead

Rain is essentially absent from the forecast through next Wednesday, with sunny or mostly clear skies dominating the week. Overnight lows in the upper 70s and low 80s will offer only modest relief, leaving homes, pavement and bodies slow to cool after sunset.

The latest forecast updates the earlier Hoodline report on Dallas' prolonged heat streak with a new advisory and an even hotter outlook into next Monday.

Plan Around The Hottest Hours

Residents should move strenuous outdoor work to early morning or evening, take frequent breaks in shade or air conditioning, and drink plenty of fluids. The National Weather Service also advises checking on older relatives and neighbors and never leaving children or pets in a parked vehicle; call 911 immediately if someone shows signs of heat stroke.
