Areas affected...Southern into eastern Kansas into western Missouri
Concerning...Severe Thunderstorm Watch 346...
Valid 180123Z - 180330Z
The severe weather threat for Severe Thunderstorm Watch 346
continues.
SUMMARY...Severe hail and wind remain possible across the entire
watch area. Storms are expected to eventually affect far northern
Oklahoma late this evening, and another watch could be required at
that time.
DISCUSSION...Storms continue to fill in along the surface trough
from near Dodge City northeastward into Missouri. A very unstable
air mass remains in place with 4000-5000 MLCAPE observed on the 00Z
DDC and TOP soundings, respectively. Good mid to high level flow
exists, especially over northeastern portions of the area with the
upper jet sinking southward. Although low-level flow remains weak, a
few cells have show midlevel rotation at times, supporting longevity
and hail size. With time, the main cold front is expected to
interact with and undercut the existing corridor of storms, with a
more linear mode expected. Then, a southward drift, which could
bring locally damaging winds into northern Oklahoma.
