Default Re: Thunderstorm & tornado stats for 2009

I glanced at the list here for a quick refresher on total tornado numbers for last year and thought the count was a little off.

According to this EC summary, there were 29 tornadoes in Ontario last year, but this list only has 28 tornadoes. We have a missing mystery tornado to locate

EDIT: After scavenging through EC severe weather summaries, looks like they confirm the 27th tornado of the season in a SWS then jump to the 29th tornado. There is no statement or summary for the 28th tornado.

AWCN11 CWTO 191705
WEATHER SUMMARY FOR ALL OF SOUTHERN ONTARIO AND THE NATIONAL CAPITAL
REGION ISSUED BY ENVIRONMENT CANADA TORONTO AT 1:02 PM EDT MONDAY 19
OCTOBER 2009.
-------------------------------------------------------------
==WEATHER EVENT DISCUSSION==
..29TH TORNADO OF THE SEASON CONFIRMED IN ONTARIO..
ON AUGUST 22ND, TWO DAYS AFTER THE RECORD-SETTING TORNADO OUTBREAK OF
AUGUST 20TH, SOUTHERN ONTARIO EXPERIENCED AN UNSTABLE AIRMASS THAT
LED TO REPORTS OF FUNNEL CLOUDS IN PORTIONS OF YORK AND DURHAM
REGIONS. PHOTO AND VIDEO EVIDENCE HAS NOW CONFIRMED THAT ONE OF THESE
FUNNEL CLOUDS WAS ASSOCIATED WITH A TORNADO IN THE HIGHWAY 407 AND
MARKHAM ROAD AREA. THE TORNADO WAS SHORT-LIVED AND DID MINIMAL
DAMAGE. IT WAS RATED AS A FUJITA SCALE ZERO TORNADO, WITH PEAK WINDS
TO 110 KILOMETRES PER HOUR. THIS IS THE WEAKEST RATING ON THE FUJITA
DAMAGE SCALE, WHICH BEGINS AT F0 AND GOES TO F5.
THIS IS THE 29TH TORNADO OF THE SEASON IN ONTARIO, EQUALLING THE
ONTARIO RECORD FOR THE MOST TORNADOES IN ONE SEASON. THAT RECORD WAS
ORIGINALLY SET IN 2006. ON AVERAGE, ONTARIO HAS 11 TORNADOES EACH
SEASON.
