Areas affected...Portions of far northeastern LA...far southeastern
AR...and central MS
Concerning...Tornado Watch 106...
Valid 121703Z - 121830Z
The severe weather threat for Tornado Watch 106 continues.
SUMMARY...Strong tornado potential is increasing across northeastern
LA into central MS early this afternoon.
DISCUSSION...Multiple tornadic circulations producing TDSs have
recently been observed with a QLCS advancing rapidly eastward across
north-central into northeastern LA. The VWP from KDGX (Jackson, MS)
shows a very strongly sheared low-level wind profile. Over 80 kt of
southwesterly flow is being estimated around 3 km AGL, with around
70 kt of 0-3 km shear present. A corridor of greater severe
potential, including the possibility of strong tornadoes and
widespread damaging winds, will likely be focused through the early
afternoon from parts of northeastern LA into central MS ahead of the
QLCS and to the south of a northward-developing warm front. Embedded
circulations within the line, or a supercell or two developing on
its southwestern flank, will pose the best potential for strong
tornadoes given the very favorable low-level shear (0-1 km SRH in
excess of 500 m2/s2).
