Weather summary
for Ontario and the National Capital Region
issued by Environment Canada
at 4:00 p.m. EST Wednesday 17 February 2016.

==Discussion==

A low pressure system originating along the Gulf coast intensified
into a major winter storm as it tracked up along the Appalachians
into Southern Quebec Tuesday evening. This winter storm brought huge
amounts of snow to a swath from Kingston to Ottawa along with heavy
freezing rain to extreme Eastern Ontario including Cornwall.

The incredibly heavy 51 cm snowfall at Ottawa Airport is a new
largest 1 day snowfall amount on record for that location.

Snowfall amounts further west in the Greater Toronto area were in
the 5 to 10 centimetre range, as this area was only grazed by the
western edge of the huge snow shield associated with this winter
storm.

Below is a summary of snowfall amounts received as of noon today:

Ottawa Airport 51 cm
Ottawa Downtown 41 cm
Gatineau Airport 40 cm estimated
Casselman 35 cm as of 6 PM Tuesday
Moose Creek 21 cm as of 6 PM Tuesday
Cornwall 25 cm plus 20 mm of freezing rain
Brockville 31 cm
Singleton 45 cm
Kemptville 40 to 45 cm estimated
Drummond Centre 37 cm
Kingston Airport 31 cm estimated
Point Petre 30 cm estimated
Trenton Airport 22 cm
Cobourg 15 cm estimated
Peterborough 10-15 cm estimated
Tapley 12 cm
Oshawa 11 cm
Grimsby 10 cm
Welland 15 cm estimated
St Catharines (on escarpment) 22 cm as of 6 PM Tuesday
Port Colborne 16 to 20 cm
Fort Erie 25 cm as of 6 PM Tuesday
