Bentonville’s Forecast Swings From Lightning to Heat Alerts — Are You Ready for July’s Weather Twist?

Bentonville, the business hub of northwest Arkansas and home to Walmart’s headquarters, is set to experience a dramatic weather shift from stormy skies to relentless summer heat over the next three days. As July 2025 kicks off, residents should prepare for wet commutes, muggy afternoons, and rising health risks tied to excessive heat.

July 1 (Monday): Showers and Storms Strike Early
The week begins on a stormy note with cloudy skies and widespread thunderstorms, especially in the late afternoon. Expect highs near 84°F and humidity levels above 80%, making it feel even more uncomfortable. Short bursts of heavy rain, lightning, and potential wind gusts could lead to minor flooding and power interruptions.

July 2 (Tuesday): Fewer Clouds, More Heat
The storms begin to pull back on Tuesday, but moisture lingers. With partly sunny skies, the temperature rises to 87°F, and the heat index creeps above 93°F. Outdoor plans should be scheduled early or late, and it’s best to avoid the sun between 1–4 PM when conditions are most oppressive.

July 3 (Wednesday): Full Sun and Full Heat Hazard
By Wednesday, sunshine dominates—but so does the dangerous heat. Expect highs of 91°F, and a heat index approaching 99°F. Local officials may issue heat advisories, urging everyone to avoid prolonged sun exposure, stay in air-conditioned spaces, and monitor children and pets closely.
