Areas affected...Northwestern Kansas...Southwest Nebraska

Concerning...Severe Thunderstorm Watch 601...

Valid 190127Z - 190330Z

The severe weather threat for Severe Thunderstorm Watch 601
continues.

SUMMARY...Strong gusts along with some hail threat continues across northwestern Kansas into southwest Nebraska.

DISCUSSION...Much of the western half of ww601 has stabilized due to
extensive convective overturning. Surface temperatures have cooled
into the 60s across northeast CO and the more buoyant air mass now
resides downstream across the central Plains. Strong, slow-moving
thunderstorms continue along a boundary that is draped from Greeley County-Ellis County KS, but even this activity has gradually
weakened over the last hour or so. Given the lack of meaningful
large-scale support, or a strong LLJ, severe wind/hail risk should
be more isolated in nature as storms propagate slowly this evening.
