CONCERNING...TORNADO WATCH 461...
VALID 252200Z - 252330Z
THE SEVERE WEATHER THREAT FOR TORNADO WATCH 461 CONTINUES.
SUMMARY...A TORNADO AND SEVERE GUST RISK WILL CONTINUE WITH ONGOING
STORMS. THE BEST CHANCE FOR TORNADOES WILL EXIST WITH LOW-TOPPED
SUPERCELLS TRAVERSING A DIFFUSE BAROCLINIC BOUNDARY.
DISCUSSION...MULTIPLE LOW-TOPPED SUPERCELLS HAVE DEVELOPED AND ARE
TRAVERSING A DIFFUSE WEST-TO-EAST BAROCLINIC BOUNDARY, WHERE STRONG
LOW-LEVEL SHEAR IS IN PLACE. THE MOST RECENT ARX VAD SHOWS A
SIZEABLE, CURVED HODOGRAPH AND NEARLY 200 M2/S2 IN THE SURFACE-500 M
LAYER. AS SUCH, TORNADOES AND SEVERE GUSTS REMAIN A CONCERN WITH THE
STRONGER STORMS, PARTICULARLY WITH ANY LOW-TOPPED SUPERCELLS THAT
CONTINUE TO TRAVERSE THE BOUNDARY, WHERE MAXIMUM INGESTION OF
STREAMWISE VORTICITY MAY BE REALIZED.
