Clarksville, TN – Clarksville and Montgomery County are heading into another stretch of hot summer weather, with mostly sunny skies and temperatures climbing toward the upper 90s and potentially reaching 100 degrees by Sunday.
Heat and humidity will make conditions feel even hotter, with Thursday’s heat index expected to reach as high as 109 degrees and Friday’s potentially reaching 107 degrees. The weekend will bring the hottest temperatures of the forecast period, making heat safety especially important for anyone spending extended time outdoors.
The combination of abundant sunshine and limited chances for rain will allow temperatures to steadily rise through the weekend. Residents should plan outdoor activities carefully, stay hydrated and take frequent breaks from the heat, particularly during the afternoon when temperatures and heat index values are highest.

Extended Heat Continues Across Clarksville-Montgomery County
The upcoming forecast calls for several consecutive days of intense summer heat, with highs ranging from the mid-90s Thursday and Friday to around 100 degrees Sunday. The elevated heat index values make the conditions even more concerning, especially for older adults, young children, outdoor workers and anyone participating in strenuous activities.
Residents should drink plenty of fluids, seek air-conditioned locations when possible and avoid strenuous activities during the hottest afternoon hours. Never leave children or pets unattended in a vehicle, and check on family members and neighbors who may be particularly vulnerable to extreme heat.
With the hot pattern expected to continue into early next week, heat safety should remain a priority across Clarksville and Montgomery County.
