Heat Safety Tips

Summer heat will continue to build across North and Central Texas with high temperatures in the upper 90s and lower 100s. A few stray thunderstorms will be possible Saturday afternoon and evening, generally across portions of Northeast Texas and the Texoma area. Keep an eye on the weather, especially if you have outdoor plans this 4th of July weekend!

Temperatures across North and Central Texas are expected to climb into the upper 90s again today. There is also the low chance (10-20%) for a couple stray showers or thunderstorms this afternoon and evening, generally along and east of the I-35 corridor.

Slightly above normal temperatures in the upper-90s and low-100s are expected next week across North and Central Texas. In addition to the heat, the week will start out with low chances (10-20%) of isolated thunderstorms. Exercise caution and heat safety when outdoors, as heat indices will be in the 100s each day next week.

With near 100° high temperatures expected this Independence Day across North and Central Texas, here is a look at the last 40 years to see how this year compares to what's "normal". Should the forecast hold, we'll be looking at a hotter than normal Fourth of July! Fortunately, rain chances remain very low across the region, with only 10-20% chances for rain east of I-35 and north of US-84.

Stay weather-aware if you are spending time on the lake this weekend. Know the forecast in advance, have a way to receive weather information while boating, and if the weather looks threatening, come ashore!

Protect yourself, your family, and your friends from the heat and sun. Stay hydrated. If outside, make sure to take frequent breaks in the shade as often as possible. Never leave kids or pets unattended! Look before you Lock!
