Areas affected...northern AL and southern middle TN

Concerning...Tornado Watch 61...

Valid 242235Z - 250000Z

The severe weather threat for Tornado Watch 61 continues.

SUMMARY...Tornado potential will likely maximize through 8pm CDT
near the AL/TN border.  A strong tornado is possible.

DISCUSSION...Trends in KHTX VAD data show a strengthening of the
wind field in the 2-3km layer during the past 1-2 hours.  This trend
seemed to be necessary in order for more organized low-level
mesocyclone development.  The intensification of flow is resulting
in around 300 m2/s2 0-1km SRH per observed storm motions.  Surface
observations show temperature/dewpoint spreads around 10 deg F and
reduced mixing compared to areas farther south.  It continues to
appear that the corridor for greatest tornado risk will focus near
the AL/TN border with the stronger updrafts/supercells through the
early evening.
