North Texas is heading into an unusually hot stretch of weather this weekend, with forecasters warning that record high temperatures could be tied or broken as early as Friday in what would be the region’s first heat wave in more than a century for this time of year.

Temperatures are expected to reach the lower 90s on Friday afternoon, matching the existing record high of 92 degrees. The warmth will build through the weekend and peak on Sunday, when highs could approach 100 degrees in some spots.

North Texas has not seen a heat wave — defined as three consecutive days at or above 90 degrees — this early in the calendar year in more than 100 years, per CBS News Texas. Friday morning will start with mild conditions, with readings in the 60s across much of the region, before climbing rapidly through the afternoon.

Officials are urging residents to take precautions as the unseasonal heat intensifies.

The heat will intensify on Saturday and peak on Sunday. Increasing winds that afternoon will raise fire danger, especially along and west of the Interstate 35 corridor, where dry conditions, gusty winds, and above-average temperatures could create critical fire weather. Residents are advised to avoid any outdoor activities that could spark fires and to remain cautious while outside.

Allergy sufferers should brace for a difficult weekend alongside the heat, as tree pollen levels have climbed into the extreme range across North Texas, driven largely by oak, elm, and ash. Dust and dander are also very high because of the gusty winds. Experts recommend keeping windows closed and changing clothes after time outdoors to limit exposure during the intense pollination period.

A cold front is forecast to pass late Sunday, offering only modest relief. Highs will dip slightly into the 80s on Monday before climbing back into the 90s by midweek, with additional record highs possible on Tuesday and Thursday.

Although the calendar still shows early spring, the extended outlook more closely resembles early summer. Forecasters are reminding people to stay hydrated, limit time outdoors during the hottest parts of the day, and follow basic heat safety practices.
