A New Tornado Watch Likely By 9:30 PM That May Include NW Alabama

Here is the text from the latest Mesoscale Discussion from the Storm Prediction Center:

SUMMARY
A squall line is organizing and shifting east across Tornado Watch #71. A new tornado watch will likely be issued by 9:30 pm CDT.

Areas affected…
Northern MS
Northwest AL
Western/Middle TN

DISCUSSION…
Large-scale forcing appears to be aiding upward evolving squall line across the Mid-South this evening. Over the last few hours a slow maturation has been noted and its forward propagation is on the order of 35kt to the east. This speed/movement would place the leading edge of strongest convection near the eastern edge of Tornado Watch #71 around 10:00 pm and through much of Middle TN into northwestern AL by 1:00 am. A new tornado watch will likely be issued by 9:30 pm.
