Areas affected...western Kansas into central Nebraska

Concerning...Severe Thunderstorm Watch 699...

Valid 032001Z - 032200Z

The severe weather threat for Severe Thunderstorm Watch 699
continues.

SUMMARY...The potential for damaging wind gusts probably will begin
to increase through 4-6 PM CDT, as a squall line continues to
develop and propagate east-northeastward.

DISCUSSION...Increasing and intensifying thunderstorm development is
now well underway, and becoming focused within the narrow corridor
of most substantive boundary-layer destabilization near the leading
edge of the stronger mid-level cooling. This is forecast to
continue advecting northeastward and eastward across central
Nebraska and western Kansas through 22-00Z. As it does, ongoing
convection appears increasingly likely to consolidate into an
organizing squall line. Gradually, the downward transfer of 30-60
kt southwesterly flow (within the 850-500 mb layer) in downdrafts is
expected to result in increasing potential for strong to severe
surface gusts. And the strengthening gust front may be accompanied
by occasionally strengthening mesovortices with locally stronger
gusts and/or, perhaps, brief tornadoes.
