ARKANSAS — A noticeable warmup is arriving across Arkansas this Wednesday afternoon, with high temperatures climbing well into the 80s statewide and a few spots potentially touching the low 90s by mid-afternoon. The region has enjoyed a stretch of cooler than average temperatures recently, making today’s heat buildup a sharp and noticeable shift for residents heading outdoors. Widespread mid to upper 80s are expected from the River Valley through central and southern Arkansas, with the warmest readings concentrated across the southern tier of the state.
Temperatures across northern Arkansas including Harrison and Mountain Home will top out in the low 80s, while communities across central and southern portions of the state see significantly warmer readings pushing into the mid to upper 80s and potentially grazing 90 degrees in isolated spots this afternoon.
Russellville Camden and El Dorado Lead the Heat With Upper 80s Across River Valley and South
The hottest readings on Wednesday are concentrated across the River Valley and southern Arkansas corridor, with Russellville, Camden, and El Dorado all forecast to reach 87 degrees. Fort Smith climbs to 86 while De Queen and Texarkana both touch 88, making the southwest corner of the state the warmest zone of the day.
Central Arkansas including Little Rock, Pine Bluff, and Arkadelphia sits right in the 85 to 86 degree range through the afternoon hours. Even the typically cooler northern communities of Harrison and Mountain Home are reaching 81 degrees today, confirming the statewide nature of this warmup.
Great Afternoon to Get Outside as Conditions Remain Dry and Comfortable Across the State
Beyond the warm temperatures, Wednesday offers an excellent window for outdoor activities across Arkansas with dry conditions and no significant storm threat in the forecast for today. The heat is notable given the recent stretch of cooler than average weather, but humidity levels are not expected to make conditions feel oppressive during the afternoon hours.
Residents are encouraged to stay hydrated and limit prolonged sun exposure during peak afternoon heating, particularly across the southern and River Valley communities where temperatures will be running the warmest today.
