Memphis, TN – A migrating heat dome is set to drive temperatures into the low to mid-90s across the Mid-South within days, while repeated rounds of heavy rain raise concerns for flooding and travel disruptions from Arkansas into Tennessee through early April.
According to the National Weather Service Climate Prediction Center, a 70 to 80 percent probability of above-normal temperatures will dominate Arkansas and Tennessee from April 3 through April 9, paired with a 60 to 70 percent chance of above-normal precipitation. Highs in Memphis, Little Rock, and Jonesboro are expected to run 10 to 20 degrees above seasonal averages, with widespread 90s likely. Overnight lows will remain warm and humid, limiting relief.
The Mid-South sits in a high-impact zone along the northern edge of the heat dome, where hot, moisture-rich air collides with incoming storm systems. This setup supports repeated rounds of showers and thunderstorms capable of producing heavy rainfall.
Rain chances remain elevated throughout the period, with the heaviest downpours likely impacting major routes including I-40, I-55, and I-30. Drivers could encounter water-covered roads and reduced visibility, especially during evening travel hours.
Residents are urged to stay hydrated, limit strenuous 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.
