Watching Broad Rotation over Marshall County

Watching for a potential tornado to form over Marshall County between Arab and Guntersville. It will pass near or west of Union Grove.

Pea-sized hail is falling in Arab.

Here is the latest from SPC:

SUMMARY…Local risk for severe weather continues, with occasionally
stronger/rotating storms.

DISCUSSION…latest radar loop shows that earlier storms which
locally had exhibited low-level rotation have diminished over the
past 1 to 2 hours. However, area VWPs — particularly across
northern portions of the WW — continue to suggest shear sufficient
for brief/local increases in low-level rotation with any
longer-lived storm.

Overall, a very slow diminishing trend in risk for stronger storms
is expected with time. However, with the upper low providing cool
mid-level temperatures, and a boundary layer that is nearly
saturated and thus not prone to appreciable diurnal cooling, minimal
but sufficient CAPE will linger into the overnight hours in areas
away from more widespread/ongoing precipitation. As such, a very
limited/local severe risk will likely continue — even beyond the
scheduled 03Z expiration of WW 513. With that said, a new WW is not
expected to be necessary at this time, though we will continue to
monitor convective trends over the next couple of hours in/near the
watch.
