LITTLE ROCK, Arkansas — The atmosphere across Arkansas is loading up for a dangerous Wednesday evening, May 6, 2026, with conditions favorable for strong tornadoes, large hail and damaging winds as scattered supercells are expected to fire by evening across a state sitting directly in the crosshairs of a powerful low-level wind shear and moisture overlap. Any storm that develops and stays isolated Wednesday evening will carry a legitimate strong tornado threat.
What the Atmosphere Is Doing
Three separate data fields valid Wednesday, May 6 at 00z paint a concerning picture for Arkansas and surrounding areas.
Low-Level Jet — 850 mb Winds The most intense winds at 850 millibars are concentrated in a deep magenta and red core centered directly over Arkansas and Tennessee, with values reaching 50 to 80 knots. This explosively strong low-level jet is the primary engine driving rotational potential for any supercell that develops Wednesday evening. The tighter the wind shear in the lowest levels of the atmosphere, the greater the tornado threat from discrete storms.
Surface Moisture — Mid-60s Dewpoints Dewpoints across Arkansas are sitting in the mid-60s Fahrenheit ahead of the approaching boundary, shown in the green shading on the dewpoint map. The dryline and surface boundary pushing from the southwest are creating a sharp moisture contrast directly over Arkansas, which is exactly where storms will be most likely to initiate Wednesday evening…
