Areas affected...South-central and southeast NE

Concerning...Tornado Watch 114...

Valid 160822Z - 160915Z

The severe weather threat for Tornado Watch 114 continues.

SUMMARY...QLCS tornadoes and severe wind gusts should remain the
primary threats with a north-northeast moving line of storms over
south-central NE.

DISCUSSION...Numerous but generally brief, mesovortices were noted
earlier along the north to eastern flank of a QLCS in south-central
NE. Measured severe wind gusts up to 67 mph have been common. The
attendant MCV centered over Dawson County appears to be advancing
north, along with its immediate downstream deep convection arc. This
orientation has become perpendicular to the low and deep-layer shear
vector which is aligned from the south, and should move along the
fringe of 60-61 F surface dew points. Farther southeast closer to
the KS border, the bowing arc is closer to slightly richer surface
dew points (62-63 F), and its orientation should favor sporadic
transient mesovortices within 40-50 kt of south-southwesterly 0-1 km
shear.
