Environment Canada: Ontario Weather Review

TORONTO, ONTARIO--(CCNMatthews - Feb. 28, 2005) - Benign was the
watchword for February 2005, which featured mild temperatures and
lower-than-normal snowfall levels. Across Ontario, monthly mean
temperatures ranged from 2 to 4.5 degrees C above February norms.

Despite these elevated values, February 2005 rated as only the mildest
February since 2002 in Southern Ontario and since 1999 in Northern
Ontario. The past month was not nearly as mild as February 1998, the
warmest Ontario on record.

As for snow, February amounts totaled 20 to 30 centimetres (cm) in
Southern Ontario, 15 to 40 cm in Northern Ontario and just 15-25 cm in
Northwestern Ontario. All of these values fell below February normal
values - however, not so far below that any records were set.

On two occasions this month, however, the work week began with
significant storms. On Valentines Day, Monday, February 14, a low
pressure system that moved up from the American Midwest brought a messy
mixture of snow, ice pellets and freezing rain to many areas in Southern
and Central Ontario. Hamilton and North Bay both experienced about five
hours of freezing rain during this event.

About a week later, another storm system again moved up from the
American Midwest and tracked along the lower Great Lakes. This storm
once again brought mixed precipitation, but slightly higher amounts of
snow. The event literally began in the Windsor area on Sunday, February
20, with a bang: a rare, but not unheard of, report of thunder at the
Windsor airport in the late afternoon. The disturbance continued
eastward into the Toronto area during the early morning hours of Monday,
February 21, which caused some issues with the morning commute to work.
General snowfall amounts near the lower Great Lakes were between 10 and
20 cm. The highest amounts, of approximately 25 cm, were recorded to the
west of Lake Ontario in the Mississauga-Milton region.
