LITTLE ROCK, Arkansas — Tuesday is shaping up as a classic isolated severe weather day across Arkansas, with storms expected to mature during the evening hours as the atmospheric setup favors discrete supercell development rather than a large organized line. Upper level winds oriented more westerly support isolated storm mode, and a modest but present low level jet provides the rotational energy needed to spin up at least a few rotating storms. Not everyone in Arkansas will see severe weather Tuesday, but the signal is consistent enough that the state should be on alert for isolated severe storms by evening.
