There will be a slight chance for an isolated thunderstorm along the Red River this evening. Otherwise, temperatures will remain hot through the evening, eventually falling into the mid 70s tonight across rural areas, and into the upper 70s to near 80 in urban areas.
It will be a scorcher this week with temperatures rising a little each day as an upper level high pressure builds over the region. Triple digit daytime temperatures will be common with warm overnight lows near 80.
With the upcoming stretch of oppressive heat, here are some heat safety tips!
Here's the difference between the Heat Advisory vs. Excessive Heat Warning. Regardless of the products in effect, you need to be sure that you are prepared. Drink plenty of water, dress of heat and reduce your time in the sun. Help the elderly, kids and pets stay cool! Never leave children, disabled adults or pets in parked vehicles. Beat the heat, check the backseat!
