Little Rock, AR – A migrating heat dome is set to push temperatures into the low to mid-90s across Arkansas within days, while a surge of heavy rain increases the risk of flooding and travel disruptions through early April.
According to the National Weather Service Climate Prediction Center, Arkansas sits in a high-impact zone from April 3 through April 9, with a 70 to 80 percent probability of above-normal temperatures and a 60 to 70 percent chance of above-normal precipitation. Highs in Little Rock, Fort Smith, and Fayetteville are expected to run 10 to 20 degrees above seasonal averages, with many areas climbing into the 90s.
The state lies along the northern edge of the heat dome, where hot, humid air collides with incoming storm systems. This setup supports repeated rounds of showers and thunderstorms capable of producing heavy rainfall and localized flooding.
Rain chances remain elevated statewide, especially during afternoon and evening hours. Heavier downpours could impact major corridors including I-40, I-30, and I-49, leading to water-covered roads and reduced visibility during peak travel times.
Residents are urged to stay hydrated, limit outdoor activity during peak heat, and avoid driving through flooded roadways.
This pattern is expected to persist through April 3–9, with additional advisories likely as rainfall totals and storm timing become more defined.
