Mesoscale Discussion 0147
NWS Storm Prediction Center Norman OK
0150 PM CST Fri Mar 06 2026
Areas affected...central/northeast KS...southeast NE...southwest
IA...and northwest MO
Concerning...Severe potential...Watch likely
Valid 061950Z - 062215Z
Probability of Watch Issuance...80 percent
SUMMARY...Monitoring for increasing severe potential this afternoon.
Initial threat should be large hail and damaging winds, with a
gradually increasing tornado threat. A watch issuance is likely.
DISCUSSION...Increasingly agitated boundary-layer cumulus is evident
over north-central KS into southeast MO -- within a zone of
low-level confluence immediately ahead of a cold front. Continued
diurnal heating amid lower 60s dewpoints should erode remaining
inhibition and favor isolated storm development over the next couple
hours. Around 1000 J/kg MLCAPE and 50-60 kt of effective shear will
promote storm organization, though generally weak large-scale
forcing for ascent casts uncertainty on individual storm longevity
initially. Nevertheless, this environment will favor discrete
supercells with a risk of large hail and damaging gusts. With time,
storms will spread/develop east-northeastward, where sheltered
boundary-layer moisture and larger clockwise-curved hodographs
(aided by a 50-kt low-level jet sampled by TOP 18Z sounding) will
favor an increasing tornado risk later this afternoon into tonight.
While timing of thunderstorm development/maturation remains
uncertain, current thinking is that a watch will likely be needed
this afternoon.
