The city of Fort Smith, Arkansas, is staring down a dramatic mix of weather conditions this week, as the forecast swings from humid thunderstorms to oppressive summer heat. Here’s a detailed breakdown of what residents can expect between July 1 and July 3, 2025.

July 1 (Monday): Thunder Rumbles and Humidity Soars
Start your week with overcast skies and scattered thunderstorms, particularly in the afternoon. With a high of around 86°F and humidity nearing 75%, expect it to feel even warmer. Winds may pick up slightly, and localized downpours could lead to brief travel delays. Keep umbrellas and caution close at hand.

July 2 (Tuesday): Breaks of Sun, Still Muggy
Tuesday brings partly sunny skies, but intermittent showers are likely, especially during early morning and late afternoon. The high will climb to 88°F, and with continued high humidity, the heat index may push past 93°F. Not an ideal day for strenuous outdoor work — take breaks and hydrate often.

July 3 (Wednesday): Intense Heat on the Horizon
By Wednesday, the sun returns in full force, but so does the intense heat. With temperatures reaching 93°F and a heat index approaching triple digits, heat advisories are likely.
