Jackson, Mississippi – Dangerous heat will continue tightening its grip on Mississippi over the next several days, with heat index values climbing as high as 115 degrees and the risk of heat-related illness increasing through midweek.
According to the National Weather Service in Jackson, much of the state will experience high temperatures in the mid to upper 90s today and Monday, while oppressive humidity pushes heat index values between 105 and 115 degrees. The highest heat stress is expected across western Mississippi, where a Level 3 Significant Heat Risk is in place. Conditions become even more widespread Tuesday through Wednesday as the significant heat risk expands across central and southwest Mississippi.
Cities including Jackson, Vicksburg, Natchez, Brookhaven, Greenwood, Greenville, Yazoo City, Hattiesburg, Meridian, Philadelphia, Columbus and Laurel will experience prolonged periods of dangerous heat. Heat stroke becomes increasingly likely for anyone spending extended time outdoors without frequent breaks, hydration and access to air conditioning.
Residents are urged to postpone strenuous outdoor work until the early morning or evening hours, drink water frequently even if they do not feel thirsty, wear lightweight clothing and take breaks in shaded or air-conditioned locations. Officials also remind residents to never leave children, older adults or pets inside parked vehicles, where temperatures can rise to life-threatening levels within minutes.
The dangerous heat will have statewide impacts on outdoor workers, athletes, utility crews and anyone attending outdoor events. Schools, sports programs and employers may need to adjust schedules to reduce exposure during the hottest part of the day.
The National Weather Service expects heat impacts to worsen through Wednesday before any meaningful relief arrives. Additional heat advisories or warnings may be issued as the prolonged stretch of dangerous temperatures continues.
