Areas affected...northwest KS
Concerning...Tornado Watch 492...
Valid 030216Z - 030345Z
The severe weather threat for Tornado Watch 492 continues.
SUMMARY...Scattered thunderstorms continue to develop across
northwest KS, with large hail and damaging wind gusts being the
primary threats. The tornado potential is beginning to decrease,
however a tornado watch remains in effect.
DISCUSSION...Training thunderstorms with embedded supercell
structures continue across the region. Surface temperatures are
beginning to diurnally cool, thus resulting in decreasing MLCAPE
values of 1000-1500 J/kg. However, low-level shear continues to
increase with the strengthening low-level jet. The Dodge City VWP
shows 0-1 km AGL shear just above 30 kt, with 55 kt of southerly
flow at 1 km AGL and a sickle-shaped hodograph. Although large hail
and damaging winds appear to be the primary threats for the
remainder of time until watch expiration, the tornado potential
still exists for any storm that can access surface-based parcels.
