AREAS AFFECTED...FAR SOUTHEAST KANSAS...NORTHEAST OKLAHOMA
CONCERNING...TORNADO WATCH 150...152...
VALID 270040Z - 270145Z
THE SEVERE WEATHER THREAT FOR TORNADO WATCH 150, 152 CONTINUES.
SUMMARY...A POTENTIAL FOR STRONG TORNADOES WILL EXIST ACROSS PARTS
OF FAR SOUTHEAST KANSAS OVER THE NEXT HOUR. TORNADO DEVELOPMENT MAY
ALSO OCCUR IN NORTHEAST OKLAHOMA.
DISCUSSION...A TORNADIC STORM IS CURRENTLY ONGOING IN FAR SOUTHEAST
KANSAS ON THE NOSE OF A MESOSCALE 30 TO 35 KNOT LOW-LEVEL JET, WHICH
IS ANALYZED BY THE RAP. THIS FEATURE SHOULD BE MAINTAINED OR
GRADUALLY STRENGTHEN OVER THE NEXT HOUR, WHICH WILL RESULT IN A
CONTINUED TORNADO THREAT. THE WSR-88D VWP CURRENTLY SHOWS GRADUALLY
VEERING WINDS IN THE LOWEST 2 KM. THIS IS RESULTING IN LOOPED
HODOGRAPH WITH 0-3 KM STORM-RELATIVE HELICITY NEAR 450 M2/S2.
LOW-LEVEL SHEAR IS LIKELY EVEN STRONGER NEAR THE LOW-LEVEL JET. FOR
THIS REASON, A STRONG TORNADO WILL BE POSSIBLE OVER THE NEXT HOUR OR
SO IN FAR SOUTHEAST KANSAS.
IN NORTHEAST OKLAHOMA, ANOTHER WELL-DEVELOPED SUPERCELL IS ONGOING.
THIS STORM WILL MOVE TOWARD THE LOW-LEVEL JET OVER THE NEXT HOUR,
MAKING TORNADO DEVELOPMENT POSSIBLE.
