Starting this weekend, Major to Extreme HeatRisk will begin spreading into the Midwest, Deep South, and southwestern U.S. As blistering as the daytime highs will be in many areas, record-warm morning lows will heighten the danger for those unable to seek cool shelter. Ensure your loved ones and neighbors stay safe from the heat, and remain #WeatherReady.

[5:34 PM] Weak forcing is limiting overall coverage in storms for us early this evening. Keep in mind that the environment is still ripe for an isolated strong to severe storm to develop, which will primarily last through the late evening hours. Stay weather aware this evening!
