Areas affected...western and central Arkansas
Concerning...Tornado Watch 197...
Valid 301953Z - 302200Z
The severe weather threat for Tornado Watch 197 continues.
SUMMARY...A line of strong to severe storms will continue eastward
the next several hours. Damaging gusts and a tornado or two remain
possible. A downstream watch will likely be needed.
DISCUSSION...The line of convection across western AR will continue
to shift east at around 35 kt the next few hours. downstream,
filtered heating has allowed temperatures to warm into the low/mid
80s amid low/mid 60s F dewpoints. Midlevel lapse rates remain
modest, but the moist environment is fostering modest instability
amid a moderately sheared environment. Given stronger heating ahead
of the line, low-level lapse rates have steepened considerable, and
this may foster a continued risk for damaging gusts into early
evening. A new watch downstream from Tornado Watch 197 will likely
be needed in the next hour.
