Practice Heat Safety

A heat advisory has been issued for much of North and Central Texas today from noon to 8 PM. Heat indices will be as high as 108° in the advisory area. This advisory will likely continue through the end of the week as heat indices each day will be near or above 105° across much of the area.

Strong high pressure and clear skies will set the stage for very hot weather across North and Central Texas the rest of this week. Highs will range from the upper-90s to the mid-100s. Accounting for humidity, heat indices will likely range from 105° to 112° each day during the afternoon and evening hours. Be sure to dress appropriately, stay hydrated, and have ways to cool off if needed should you plan to be outdoors this week.

Heat will continue to slowly build across North and Central Texas today with some (particularly in North Texas) seeing highs near or just above 100°. There is a very low chance (10-15%) for a stray shower or thunderstorm to develop across northeast Texas owing to the exceptionally humid airmass in place. However, the vast majority of those across the area will remain dry.

With very hot temperatures on the horizon for those of us in North and Central Texas, take time to review ways to protect yourself from heat and sun should you need to be outside during the afternoon and evening hours this upcoming week.
