Areas affected...central/eastern Kansas and northwestern Missouri
Concerning...Severe Thunderstorm Watch 101...
Valid 120103Z - 120200Z
The severe weather threat for Severe Thunderstorm Watch 101
continues.
SUMMARY...The severe threat continues across WW 101.
DISCUSSION...Storms that initiated between/west of MHK and EMP have
gradually evolved into a cluster and have moved northeastward toward
the Topeka area. These storms have primarily been hail producers,
with multiple reports of 1-1.75 inch hail and an isolated 2-inch
report. These reports are not suprising given the steep-lapse-rate
environment in place across the region.
Latest guidance/observations suggest that these storms will continue
on their trek northeastward through the I-70 corridor between Topeka
and Kansas City areas, maintaining a hail risk as they do so. An
estimated 45-50 knot storm motion should place storms near/north of
the Kansas City metro in the 0130Z/0230Z timeframe.
Farther southwest, only isolated, sub-severe convection has managed
to maintain itself across far northwestern Oklahoma, and this
convection may reach southwestern portions of WW 101 over the next
hour. The extent of the severe threat in this region (upstream of
the eastern Kansas cluster) is a bit uncertain. Convective trends
will be monitored, but it is likely that portions of the WW near the
I-135 corridor may be cancelled well before the 04Z scheduled
expiration time.
