Concerning...Tornado Watch 490...491...
Valid 020114Z - 020315Z
The severe weather threat for Tornado Watch 490, 491 continues.
SUMMARY...Scattered thunderstorms continue to develop and move into
portions of central NE and north-central KS, posing a threat for
large hail. Although the threat for tornadoes is beginning to
decrease, tornado and severe thunderstorm watches remain in effect
across the region.
DISCUSSION...Storms across central NE have begun to grow upscale
into a linear system that should continue to move eastward for the
next few hours. These storms will continue to pose a threat for
damaging winds and some isolated hail potential where the
environment out ahead remains marginally favorable, with MLCAPE
values remaining above 1000 J/kg. Farther south across
north-central KS, an isolated supercell continues to move
east-northeastward, with large hail reported. The threat for a
tornado remains possible with this storm as low-level shear should
continue to strengthen over the next few hours as evident in the
Hastings VWP. However, increasing convective inhibition should lead
to the storm's demise.
