Concerning...Tornado Watch 320...323...324...
Valid 270121Z - 270245Z
The severe weather threat for Tornado Watch 320, 323, 324 continues.
SUMMARY...Threat for significant-severe gusts is increasing within
the ongoing convective line from southeast Illinois and southern
Indiana into western Kentucky and far southeast Missouri/Missouri
Bootheel.
DISCUSSION...Well-organized convective line continues to push
quickly southeastward across southern IL and southeast MO/MO
Bootheel. Recent storm motion with this line was estimated around 50
kt, which would bring the line into central KY and southern IN
between 0230 and 0300Z. Several severe gusts have been noted within
the line, including recently at KSLO at 56 kt.
This northeast-to-southwest orientated line is about to intersect a
west-to-east line of supercells across far southern IL into far
southwest KY. This interaction is expected to result in
intensification of the line, with some potential for this area to to
surge eastward, becoming the apex of the bow. Significant-severe
gusts (i.e. 75-90 mph) are likely within this vicinity over the next
few hours. Northern portion of the bow remains well-organized, with
some interaction with the newly strengthening warm-air advection
cells across southern IN. Significant-severe gusts appear possible
here as well.
An embedded supercell persists at the southern end of the line, with
another supercell in its wake to the west over Carter County MO.
Both of these cells will continue to pose a risk for all severe
hazards for the next hour or two.
