Areas affected...Southeastern Colorado into Western Kansas
Concerning...Severe Thunderstorm Watch 169...
Valid 250113Z - 250245Z
The severe weather threat for Severe Thunderstorm Watch 169
continues.
SUMMARY...The severe weather threat across WW 169 continues into the
evening, with large hail and damaging winds the primary hazards.
Some downstream watch extensions may be necessary as a linear
convective segment matures moving into western Kansas.
DISCUSSION...The severe weather threat for WW 169 continues this
evening, particularly across northern portions of the watch area in
southeastern Colorado, as thunderstorm clusters have begun to
loosely organize into a linear convective segment. While the overall
coverage of severe storms has been low thus far, SPC surface
mesoanalysis data show MUCAPE increasing with eastward extent,
coupled with deep-layer bulk shear of 40-45 kts. This should support
continued organization of the linear convective complex as it moves
into western Kansas, shifting gradually from a hail/wind threat to a
primarily damaging wind threat later into the evening.
