CONCERNING...TORNADO WATCH 490...
VALID 042350Z - 050145Z
THE SEVERE WEATHER THREAT FOR TORNADO WATCH 490 CONTINUES.
SUMMARY...THE SVR-TSTM/TORNADO RISK CONTINUES IN WW 490.
DISCUSSION...RADAR LOOPS SUGGEST SEMI-DISCRETE SUPERCELLS BECOMING
ESTABLISHED FROM THE WICHITA AREA SWD INTO FAR NRN OK. THIS ACTIVITY
WILL LIKELY TRACK ENEWD DURING THE NEXT COUPLE OF HOURS. SVR
HAIL/WIND MAY OCCUR. THE ICT VWP INDICATES AROUND 200 M2/S2 OF
0-1-KM SRH...AND FURTHER GAINS IN LOW-LEVEL SRH MAY OCCUR WITH
NOCTURNAL DECOUPLING OF THE BOUNDARY LAYER...PRIOR TO SUBSTANTIAL
INCREASES IN MLCINH. A TORNADO COULD OCCUR WITH THE MOST
DISCRETE/SUSTAINED UPDRAFTS.
MORE QUASI-LINEAR MODES ACCOMPANY ONGOING CONVECTION FARTHER N FROM
NERN KS INTO SERN NEB...AND THIS ACTIVITY WILL CONTINUE SPREADING
EWD/NEWD. DMGG WINDS...SVR HAIL...AND POSSIBLY A BRIEF TORNADO COULD
ACCOMPANY THIS ACTIVITY EVOLVING AMIDST STRONG LOW-LEVEL/DEEP SHEAR.
