The severe weather threat for Tornado Watch 172 continues.
SUMMARY...Damaging winds will become the primary threat as
quasi-linear storms move into WW 172. Some tornado risk will remain
with line-embedded circulations. These risks will maximize
near/south of the warm front that will slowly move north.
DISCUSSION...Quasi-linear storms with embedded bowing segments
continue across eastern Oklahoma. These storms will approach the
Arkansas/Oklahoma border within the next hour or so. Part of this
activity will likely remain north of the warm front, though the
boundary will shift northward some as the surface low shifts into
Missouri. While damaging winds are expected to become the primary
threat, low-level shear will continue to support some threat for
QLCS tornadoes along the line as well. These threats should be
maximized near and just south of of the warm front. With increasing
convective inhibition with time, a weakening trend is expected by
the time storms move into parts of central/southern Arkansas. WW 172
