Extreme Heat Watch Issued for West Tennessee Through July 2
Heat index values could hit 110 degrees across West Tennessee and surrounding states as federal forecasters issue back-to-back heat alerts running through July 2.
MEMPHIS, TENNESSEE — The National Weather Service in Memphis issued both a Heat Advisory and an Extreme Heat Watch Saturday for portions of West Tennessee, warning residents of dangerous heat index values expected to reach as high as 110 degrees through the coming week.
The alerts, issued at 11:54 a.m. CDT on June 27, affect portions of East Arkansas, North Mississippi, Southeast Missouri, and West Tennessee.
What the Alerts Cover
The Heat Advisory runs from 11 a.m. Sunday, June 28, through 11 a.m. CDT Monday, June 29, with heat index values up to 108 degrees expected during that period. The more serious Extreme Heat Watch takes effect Monday morning and extends through Thursday evening, July 2, at 8:00 p.m. CDT.
During the Extreme Heat Watch period, the National Weather Service warns of dangerously hot conditions with heat index values potentially reaching 110 degrees. The combination of high temperatures and elevated humidity drives heat index readings well above actual air temperatures.
Health Risks
According to the National Weather Service, heat-related illnesses increase significantly during extreme heat and high humidity events. Officials warn that hot temperatures paired with high humidity can cause serious heat illnesses for those who are exposed.
Residents in the affected areas — including West Tennessee — are urged to limit outdoor activity during the hottest parts of the day, stay hydrated, and check on elderly neighbors and others who may be vulnerable to heat-related illness.
Affected Region
The alerts cover a multi-state area including portions of East Arkansas, North Mississippi, Southeast Missouri, and West Tennessee. The National Weather Service Memphis office issued both alerts and is monitoring conditions through the July 4th holiday weekend.
Residents should monitor updates from the National Weather Service as conditions develop heading into next week.
