Dangerous Heat and Oppressive Humidity Smothering the South With Feels-Like Temperatures Near 93 Degrees Before Noon Sunday
SOUTHERN UNITED STATES — An oppressive combination of heat and humidity is already producing feels-like temperatures near 93 degrees across parts of the South Sunday morning, and conditions are expected to intensify further through the afternoon. The heat is arriving ahead of full daytime heating, signaling a dangerously uncomfortable day for residents across the region. The left panel of the temperature map shows deep orange and red coverage dominating the South, confirming widespread extreme surface heat.
Feels-Like Temperatures Approaching 93 Degrees Before Lunch Across the South
Parts of the South are already registering heat index values near 93 degrees before noon, with actual surface temperatures in the upper 80s to low 90s visible across the map. The combination of high dewpoints and morning heat is making conditions feel suffocating well before peak afternoon heating arrives. This is not a dry heat situation — humidity is a significant compounding factor driving the dangerous feels-like readings.
Deep Orange and Red Temperature Coverage Dominating the Southern Map
The surface temperature analysis shows intense orange and red shading blanketing Texas, Louisiana, Mississippi, Alabama, and surrounding states. Observed temperatures on the map range from the upper 70s along the coast to the low 90s further inland, with some readings approaching 94 degrees in the deepest red zones. The contrast with the cooler blues visible in the northern plains highlights how extreme the southern heat footprint currently is.
Afternoon Hours Will Push Conditions Further Into the Dangerous Range
With morning readings already this elevated, afternoon peak heating between 2 and 5 PM will push heat index values significantly higher across the affected areas. Staying hydrated, limiting outdoor exposure during peak hours, and wearing lightweight breathable clothing are essential steps for anyone spending time outside. Those without air conditioning should seek cooling centers as conditions deteriorate through the afternoon and early evening hours.
