The severe weather threat for Severe Thunderstorm Watch 309
continues.
SUMMARY...Severe threat continues across ww309.
DISCUSSION...LLJ is beginning to strengthen across the TX Panhandle
into western KS where it is forecast to approach 40kt over the next
few hours. This appears to be partly responsible for recent increase
in convection along/just north of the boundary near HLC.
Additionally, thunderstorm cluster east of CNK is intensifying with
a substantial hail signature noted with this slow-moving convection.
Over the next few hours an extensive, elongated corridor of
thunderstorms should evolve north of I-70 across KS, extending into
northern MO. Latest radar data suggests an MCV is beginning to
evolve with the High Plains convection near IML and this should
encourage downstream storms north of the boundary as well. Overall,
a slowly sagging band of storms should drop south with time if a
sufficient cold pool develops.
