Areas affected…Arklatex into Southeastern/Central Missouri

Concerning…Tornado Watch 143…

Valid 270114Z – 270315Z

The severe weather threat for Tornado Watch 143 continues.

SUMMARY…Severe threat continues in WW143.

DISCUSSION…A broken line of storms continues from Arklatex into
central Missouri as with a history of reports of damaging wind up to
50-65 mph. Intensity has come down within much of this line after
loss of daytime heating. Surface objective analysis would suggest
that MLCIN is increasing, though it is noted in surface observations
that temperatures remain in the mid 70s northeast of Little Rock.
Lightning activity within this portion of line also remains very
productive. This portions of the line will maintain a damaging wind
threat in the short term.

On the tail end of the line, surface objective analysis indicates
that minimal surface-based buoyancy may be available. Storms across
this region in northeastern Texas from Mount Pleasant, TX to
Texarkana have maintained intensity but should generally weaken as
heights rise and the airmass continues to become less favorable.
Potential for damaging wind and hail will continue in the short term
in this region.
