-------------------------------------------------------------
==WEATHER EVENT DISCUSSION==

AFTER CONTINUED STUDY OF THE DAMAGE PATTERN AND THE RADAR IMAGERY
FROM THE JUNE 6 TORNADO EVENT IN THE HARROW AND LEAMINGTON AREA, THE
EVENT HAS BEEN REASSESSED FROM A SINGLE FUJITA SCALE TWO TORNADO
(WITH PEAK WINDS OF 180 TO 240 KM/H) TO THREE SEPARATE TORNADOES.

THE FIRST TORNADO FROM THIS EVENT OCCURRED SOUTH OF HARROW, BETWEEN
