Areas affected...Arkansas

Concerning...Severe Thunderstorm Watch 152...

Valid 202158Z - 202330Z

The severe weather threat for Severe Thunderstorm Watch 152
continues.

SUMMARY...Severe threat continues across ww152.

DISCUSSION...Scattered strong/severe convection continues across
mainly the western half of ww152. This activity is mixed mode with
clusters, short line segments, and isolated supercells. Latest MRMS
data suggests the strongest updrafts are likely producing hail,
though most cores are generating hail on the order of 1 inch or
less. The majority of convection is currently encountering the
greatest buoyancy with the instability axis extending from northeast
TX into the Ozarks. Over the next few hours this activity will
spread east of the instability axis where less favorable
moisture/instability reside. Until then, hail and wind remain
possible.
