Areas affected...eastern Oklahoma into far western Arkansas

Concerning...Tornado Watch 18...

Valid 041222Z - 041445Z

The severe weather threat for Tornado Watch 18 continues.

SUMMARY...A squall line with history of damaging winds may remain
severe as it approaches the Arkansas border.

DISCUSSION...Surface analysis shows a warm front remains over
northeast OK and extending southward roughly near the OK/AR border.
Pressure falls are currently strong in this region with over 2 mb
falls per hour noted. As such, it is likely that the low-level jet
is transporting higher theta-e air northward, perhaps just off the
surface. Therefore, while surface observations otherwise indicate
weak/marginal instability extending into the northwest AR area, it
is not inconceivable that the line remains severe into those areas
with damaging wind potential.=20

Depending on storm trends, an additional small watch cannot be ruled
out.
