Areas affected...southeast GA and far northeast FL

Concerning...Tornado Watch 68...

Valid 232150Z - 232245Z

The severe weather threat for Tornado Watch 68 continues.

SUMMARY...A strong storm or two remains possible over the next hour,
though the overall severe threat is expected to wane and shift
offshore through 23z/7pm EDT.

DISCUSSION...A moist and modestly unstable airmass remains across
northeast FL/southeast GA where surface dewpoints are in the upper
60s to low 70s F. This moist axis is contributing to moderate 3 km
CAPE values amid 40-50 kt effective shear magnitudes. However, rain
and thunderstorms through the afternoon have likely lead to some
convective overturning. Additionally, the low-level vorticity max
has shifted east of the coast, and late afternoon water vapor loops
show a midlevel speed max ejecting east of the FL/GA/SC coast. As a
result, waning ascent over the region will limit further convective development. While a strong storm or two remains possible in the
short term near the coast, the overall threat is expected to
diminish over the next couple of hours.

Areas affected...North-central MS

Concerning...Tornado Watch 76...

Valid 250113Z - 250215Z

The severe weather threat for Tornado Watch 76 continues.

SUMMARY...An intense tornado (EF3+) is likely ongoing with a
supercell tracking northeastward across western Sharkley County MS,
and this storm should persist for the next 30-60 min.

DISCUSSION...Latest radar data shows an organized cyclonic supercell
tracking northeastward across western Sharkley County MS, with a
VROT above 70 kt and well-defined TDS up to 13k ft -- indicative of
an intense tornado (EF3+) given the parameter space (STP of 4). The
downstream environment features a large, clockwise-curved hodograph
per DGX VWP (around 430 m2/s2 0-1 km SRH) amid rich boundary-layer
moisture. This will support the maintenance of this intense
supercell toward the northeast for the next 30-60 min.

Areas affected...eastern Missouri across Illinois and into far
southwest Indiana.

Concerning...Tornado Watch 68...

Valid 012345Z - 020115Z

The severe weather threat for Tornado Watch 68 continues.

SUMMARY...Training supercells will continue along a warm front from
eastern Missouri to far western Indiana this evening.

DISCUSSION...A mature supercell is moving through the northern St.
Louis suburbs with another supercell east of Jefferson City. Thus
far, the maximum hail size with these storms has been golf ball
sized, but even larger hail is possible, especially as the low-level
jet strengthens this evening. A vorticity rich environment along
this warm front will support a tornado threat through the evening
with the WoFs suggesting a narrow corridor of 2 STP along the front.
WoFs 0-2km UH probabilities suggest the lead supercell will continue
to support a tornado threat for the next several hours with peak
probabilities in south-central Illinois.
