A bit of a sleeper event today under a belt of 60-80kt westerly winds aloft ahead of the upper wave. Models now showing dewpoints reaching the 60F mark in much of northeastern Arkansas, western Tennessee and the Missouri bootheel region this evening/night. With decent turning in the low levels thanks to a weak surface low, ~1500 MLCape along with looping albeit small hodographs yield 0-3km SRH peaking at 300-350. Negatives are weak surface flow and, from a chasing standpoint, the event peaking well after sunset. Visible satellite shows good insolation is happening along the MO/AR border area northward, and CAMs indicate supercell development around 00z. This is close enough that I may head down there to take a look. Lightning should be plentiful enough to observe storm features after dark.
