Little Rock, Arkansas – Arkansas sunshine will push pavement temperatures higher today before Little Rock makes a run at 99 degrees Sunday.

According to the National Weather Service, Little Rock reaches 95 degrees today. Winds remain light before turning east near 5 mph.

Conditions were already warming by midmorning. Adams Field reported 77 degrees at 8:53 a.m., with a heat index of 79.

The more significant heat arrives Sunday. The NWS calls for 99 degrees, with heat index values reaching 102.

Anyone attending outdoor events should plan water and cooling breaks before afternoon temperatures peak. Never leave children or pets inside parked vehicles.

Sunday morning starts near 68 degrees before temperatures climb roughly 31 degrees. That rapid daytime warming will make the afternoon feel dramatically different.

Monday brings another 99-degree high. Tuesday eases slightly to 97, before Wednesday rebounds to 98.

Morning temperatures also trend upward. Lows rise from 68 degrees to the middle and upper 70s by early next week.

That means homes without effective cooling get less relief before another hot afternoon begins.

Drivers on I-30, I-40 and I-630 should check tires and coolant before longer trips. Keep drinking water inside the vehicle.

The supplied NWS data shows dry conditions through Wednesday. It does not indicate thunderstorms, snow, ice or a tornado threat for Little Rock.

The national Weather Prediction Center discussion highlights storms elsewhere. Those broader risks should not be interpreted as a Little Rock severe-weather threat.

Heat remains the developing story instead. Thursday could reach 100 degrees before Friday returns to around 99.

With several consecutive hot days ahead, residents should monitor updated NWS alerts as September approaches.
