Mesoscale Discussion 0299
NWS Storm Prediction Center Norman OK
0549 PM CDT Wed Apr 10 2019
Areas affected...North-central Kansas into southeast Nebraska
Concerning...Severe potential...Watch likely
Valid 102249Z - 110045Z
Probability of Watch Issuance...80 percent
SUMMARY...A few severe storms capable of mainly damaging hail may
develop after 00Z.
DISCUSSION...A surface low continues to deepen across central KS,
and will track northeastward into southeast NE this evening. The
synoptic setup overall is quite favorable for severe storms with
steep lapse rates aloft, strong wind profiles, and lift. However,
moisture is a major concern. GPS PW sensors indicate values
approaching 0.60" near Wichita, but a band of relatively greater PW
does exist near the stationary/developing warm front from near
Kansas City into southeast NE.
Recent visible imagery and radar shows skeletal convection forming
near Russell KS as of 23Z, ahead of the low. The zone from here
northeastward appears to have the greatest chance of severe storms
capable of large hail. Supercells are possible, either elevated, or,
surface based right along the front, with an enhanced risk of
damaging hail. While low-level moisture is a concern, a conditional
tornado risk still exists given favorable storm mode, steep lapse
rates, lift along the boundary, and increasing low-level SRH.
