As the days march steadily toward the heart of summer, Dallas residents can expect temperatures to rise steadily this week. Today, the skies will transition from mostly cloudy to sunny, with a daytime high near 94 degrees. Notably, the heat index—a measure that factors in humidity to reflect the perceived temperature—could reach as high as 99, according to the latest forecast from the National Weather Service.

The temperature trend is set to continue through the week, with the National Weather Service predicting sunny skies and a high near 95 degrees for Tuesday. And let's not forget the heat index, which is expected to climb even higher to potentially hit 105. The accompanying south wind will pick up pace, possibly reaching gusts as high as 25 mph. Meanwhile, Tuesday night won't offer much respite, with temperatures holding steady around a low of 77 and similar windy conditions.

Wednesday's outlook remains consistent, promising mostly sunny skies with highs maintaining the mid-90s mark. As the week progresses, these patterns firmly hold their grip. The evening will be partly cloudy, but it will stay a warm 77 degrees. This is all indicative of a typical Texas summer settling in—warm, with a preference for clear, sun-drenched days and minimally cooler nights.

The forecast for Juneteenth, an important day of reflection and celebration, also shows Dallas bathing in mostly sunny conditions. The high could reach near 96 degrees, with a comforting yet persistent south-southwest wind to gently blow at 5 to 10 mph. As the week draws to a close, Friday's weather is expected to be particularly sunny, edging towards a high of 97 degrees. Southern winds will remain steadfast, occasionally picking up enough to swiftly gust up to 20 mph.

The weekend outlook, starting Saturday, is set to mirror the majority of the week, with sunny skies and highs hovering around the 95-degree mark. Nighttime temperatures will drop slightly to an agreeable 76 degrees. And the serenity of sunny conditions will provide a backdrop to Sunday activities, culminating in a high near 94 degrees for the day.
