Areas affected...Northeast TX/Northwest LA into central/northern AR
Concerning...Tornado Watch 113...
Valid 042233Z - 050000Z
The severe weather threat for Tornado Watch 113 continues.
SUMMARY...Tornado potential, including a strong (EF2+) tornado risk,
will be maximized through early evening across the ArkLaTex,
especially across far northeast Texas into southwest Arkansas, while
also increasing across north-central Arkansas. Tornado Watch 113
continues until 9pm CDT/02z.
DISCUSSION...Multiple intense supercells are ongoing at 525pm
CDT/2225z across far northeast Texas and extreme southeast
Oklahoma/far southwest Arkansas, including a particularly intense
supercell with prior tornadic history in Upshur County about 25
miles north of Longview. While the storm mode is complex, the
environment remains highly favorable for tornadoes, potentially
including a strong tornado risk amidst 150-200 m2/s2 0-1km SRH and
lower 70s F dewpoints with T/Td spreads of 10-15F.
Farther north, semi-discrete supercells have intensified across
north-central Arkansas, and this trend is likely to continue with an
increasing tornado potential across this region. This zone will be
increasingly influenced by a pronounced early-evening strengthening
of the low-level jet, with current surface observations of
2.0-3.5mb/2-hourly pressure falls and dewpoints having recently
increased several degrees.
