There is an elevated risk of severe thunderstorms across much of
eastern Oklahoma and western Arkansas during the late
afternoon and evening hours today. Large hail to golfball size,
damaging winds to 70 mph, and an isolated tornado will all be
possible, especially with the initial development along and south
of I-40 in southeast Oklahoma along a residual outflow boundary.
The threat will transition to primarily a damaging wind threat as
storms congeal into a complex and move east or southeast toward
western Arkansas during the evening. Locally heavy rainfall is
possible as well, and could lead to some flooding if storms train
over areas that received heavy rainfall from this morning`s
storms.
Heat indices near 100 degrees are forecast this afternoon near the
Red River.
