March 19 All Day Severe Weather Situation #008

This is a follow-up to the Severe Weather Situation #007.
Above is the SPC radar return with risk areas.
Radar returns indicate the strongest storms may be developing at this time. Pop-up Storms are developing in Oklahoma and Kansas. I do feel the slight risk area will need to be expanded north to account for those pop-up storms.
12z RUC indicates moderate instability by Best Lifted Index in east Oklahoma into extreme southern portions of Kansas.
Most Unstable CAPE values are around 1000 j/kg in the designated areas, indicating an atmosphere that is still in some control of itself.
Will monitor this situation and issue more follow-ups if necessary.

UPDATE 9:51AM CDT
A severe thunderstorm watch has been issued for the area in the above image in blue.
