Areas affected...Central High Plains
Concerning...Severe Thunderstorm Watch 249...
Valid 310110Z - 310315Z
The severe weather threat for Severe Thunderstorm Watch 249
continues.
SUMMARY...Severe threat will gradually spread across much of ww249.
Hail/wind remain possible.
DISCUSSION...Several thunderstorm clusters have evolved across the
central High Plains in partial response to a weak short-wave trough
that currently extends from eastern WY into eastern CO. One complex
in particular extends across northwestern KS, arcing southwest into
western portions of ww250. While 850mb flow remains weak across
western KS, some nocturnal increase will likely occur within the
next few hours such that the maturing MCS along I-70 should begin to
propagate a bit faster toward the southeast, especially if the cold
pool continues to expand.
Another notable slow-moving MCS is evolving over the NE Panhandle
with more isolated strong/severe convection extending into northeast
CO. Strongest portions of this activity are producing hail around 1
inch. Overall, strong/severe convection should gradually spread
across the remainder of ww249 by late evening.
