Frost warning for
Barrie - Collingwood - Hillsdale continued
..Patchy frost early this morning..
This is a warning that at or near zero ground temperatures will cause
frost in the parts of these regions. Monitor weather conditions..Listen
for updated statements.
A ridge of high pressure over central Ontario has brought cool generally
clear skies across parts of the lower Great Lakes. As a result..Frost is
expected over the above regions early this morning with the mercury
hovering close to the freezing mark in many areas.
Tender plants outdoors should generally be protected from frost.
Somewhat milder conditions this coming night should minimize the risk of
frost. Thus this warning will be ended once the threat of frost passes
later this morning and will not likely be re-issued for this coming night |

Winter storm warning for
Barrie - Collingwood - Hillsdale continued
..Major winter storm affecting southern Ontario..
This is a warning that dangerous winter weather conditions are imminent or
occurring in these regions. Monitor weather conditions..Listen for updated
statements.
The winter storm which is affecting most of southern Ontario is now
centred over Pennsylvania. This storm will continue to push northwards
towards the St Lawrence Valley tonight giving significant snow amounts to
most of southern Ontario. The first shot of snow began Friday morning over
areas north of the lower Great Lakes and last evening across eastern
Ontario and ski country. The second round of heavy snowfall associated
with this storm began this morning. The heavy snow will gradually taper
off from west to east tonight.
Storm totals will likely be near 25 centimetres along and east of a line
from London to lake Simcoe then to Petawawa. There is potential for 40 to
50 centimetres of snow over eastern Ontario including Ottawa by the time
this storm system moves out. Areas west of the London to Petawawa line
should see between 10 and 20 centimetres with lesser amounts near Lake
Huron and Georgian Bay. Regions located near the St Lawrence Valley will
see ice pellets and a risk of freezing rain mixed with the snow this
evening.
Strong northerly winds with gusts up to 70 km/h are accompanying this
storm. The strong winds combined with fresh snow is causing blowing snow
and whiteout conditions thereby creating dangerous driving conditions. The
winds will slowly diminish in strength tonight.
Travellers should be prepared to change their plans accordingly. Areas
north of Lake Ontario and into the St Lawrence Valley should not be
surprised by the occurrence of some thunder and lightning as this vigorous
low passes by tonight.
Environment Canada will continue to monitor the situation to update
watches and warnings as required. |

A storm is currently over North Carolina this morning and will push
northward today giving significant snow to most of southern Ontario. The
first round began Friday morning over areas north of the lower Great Lakes
and last evening across eastern Ontario and ski country. The Niagara
Peninsula and Ottawa have already received about 17 centimetres as of 4
AM. Snow has become light and more intermittent this morning. The heaviest
snowfall is expected in the second round beginning this afternoon in the
southwest and this evening over eastern Ontario. Keep in mind that the
snowfall duration will be about 36 hours but the heaviest snow will be
this afternoon into this evening.
Storm totals will likely be 30 to 40 centimetres along and east of a line
from St Thomas to Barrie then to Petawawa. There is potential for 40 to 50
centimetres of snow over the Niagara Peninsula and parts of Haliburton
Highlands into Pembroke. Areas west of the St Thomas to Petawawa line
should see between 10 to 20 centimetres with lesser amounts near Lake
Huron and Georgian Bay. With the warm front just to the south of the St
Lawrence Valley these regions may expect ice pellets and a risk of
freezing rain this afternoon. Behind this system strong northerly winds to
70 km/h are likely. Strong winds combined with fresh snow will cause
blowing snow and local whiteout conditions creating dangerous driving
conditions. Blowing snow will be the main concern for areas from Windsor
to Sarnia to Owen Sound and hence a blowing snow warning is in effect for
these areas.
Travellers should be prepared to change their plans accordingly. Areas
north of Lake Ontario and into the St Lawrence Valley should not be
surprised by the occurrence of some thunder and lightning as this vigorous
low passes by late today.

Snowsquall warning for
Barrie - Collingwood - Hillsdale issued
..Snowsqualls expected tonight..
This is a warning that snowsqualls are imminent or occurring in these
regions. Monitor weather conditions..Listen for updated statements.
Cold Arctic air continues to blast into southern Ontario today in the wake
of a cold front that moved through last evening. Strong winds ushering in
this air mass will once again cause a number of winter severe weather
problems across parts of southern Ontario today and tonight.
Wind warning.
Brisk southwesterly winds in the wake of last weekends winter storm with
sustained winds of 60 km/h with a few gusts to 90 km/h will continue to
occur in the regions near the east end of Lake Erie and in the exposed
southern parts of Prince Edward county. Winds will slowly start to
diminish beginning this afternoon.
These winds will be strong enough to cause minor damage to trees and
buildings as well as toss loose items about. Extra caution is also advised
for motorists as the strong winds may make driving rather difficult.
Blowing snow warning.
A blowing snow warning is in effect for the Picton - Sandbanks Park region
which is receiving some lake effect flurries off of Lake Ontario. Blowing
snow will result in nil visibility in whiteout conditions at times today
along with dangerous winter driving conditions as a result.
Snowsquall warning.
In the Grey - Bruce and Barrie - Orillia - Midland regions flurries heavy
at times today will become better organized into a few snowsqualls this
evening as a trough of low pressure moves in from the northwest. Local
snowfall amounts near 15 cm are likely in the snowsqualls tonight.
Motorists in these regions should be prepared for sudden nil visibility in
whiteout conditions from bursts of heavy snow and local blowing snow
beginning this evening. Hazardous winter driving conditions are expected. |

Freezing rain warning for
Barrie - Collingwood - Hillsdale continued
..Several hours of freezing rain today..
This is a warning that an extended period of freezing rain is imminent or
occurring in these regions. Monitor weather conditions..Listen for updated
statements.
A large scale winter storm - currently over Missouri this morning - will
track northeast towards the Great Lakes reaching northern Lake Huron early
Monday morning. Associated with the storm is a band of freezing rain that
will March across southern Ontario today reaching eastern Ontario this
afternoon.
The freezing rain will begin in southwestern Ontario early this morning
and Progress eastward reaching the greater Toronto area late this morning.
In eastern Ontario precipitation will begin as a brief period of snow
before switching to freezing rain. The freezing rain should reach the
Ottawa area this afternoon.
Current indications show that between 2 and 4 millimetres of freezing rain
will fall over a 2 to 3 hour period before the change over to rain occurs.
However there are indications that the freezing rain may persist longer -
up to 6 hours - over portions of the Ottawa Valley. |

9:59 PM EST Wednesday 6 February 2008
Snowfall warning for
Barrie - Collingwood - Hillsdale continued
Snow heavy at times expected this evening for much of southcentral Ontario
with 15 to 20 centimetres accumulation likely by Thursday morning.
A major winter storm producing very heavy snow with lingering freezing
rain and ice pellets is now pounding southern Ontario as advertised.
The deepening low pressure system responsible for this major winter storm
is over northwestern Indiana and will move northeast near a line from
Windsor to Niagara to eastern Lake Ontario by Thursday morning. A large
area of moderate to heavy snow extends all the way back to Lake Michigan
from this storm this evening. There have also been reports of thunder and
lightning across parts of southern Ontario into the greater Toronto area
as well.
Freezing rain and ice pellets continue to fall from London and St Thomas
in the west to Hamilton and Niagara in the east where the freezing rain
warning remains in effect. This freezing precipitation will change over to
snow heavy at times this evening as the storm centre passes by and colder
air moves in from the north. Hence total snowfall amounts in these areas
will be reduced from those further north with 5-10 centimetres likely near
Lake Erie by morning and 10-15 centimetres likely in the London to
Hamilton areas. Ice accretions of a few millimetres have been reported in
this area by trained weather spotters.
The northern reaches of this winter storm will experience snowfalls of 15
to 20 centimetres which is below the 25 centimetres criterion for winter
storm warning but meets the criterion for snowfall warning.
This storm will produce snowfall rates as high as 5 centimetres per hour
with near zero visibilities especially during the evening hours. The area
of heavy snow will very gradually weaken as it moves eastward and the low
pressure system starts to lose some of its steam giving eastern portions
of the province slightly lesser amounts.
The highest snowfall from this system is expected to fall over the
Goderich to Palmerston to Orangeville to Newmarket areas tonight with
upwards of 30 centimetres possible there by Thursday morning. Elsewhere in
the path of this wave of precipitation a general 15 to 25 centimetres of
snow is likely.
Motorists are very strongly encouraged to drive extremely carefully as
dangerous winter driving conditions from zero visibility in whiteout
conditions from bursts of very heavy snow and local blowing snow continue.
Travelling should be delayed if at all possible until after the storm ends
overnight. |

5:07 AM EST Friday 1 February 2008
Winter storm warning for
Barrie - Collingwood - Hillsdale continued
Snow heavy at times is expected across all of southern and eastern Ontario
with a possibility of freezing rain and ice pellets along lakes Erie and
Ontario.
This is a warning that dangerous winter weather conditions are imminent or
occurring in these regions. Monitor weather conditions..Listen for updated
statements.
A low pressure area over southern Indiana is moving northeastward and
setting its sights on southern Ontario. As the low moves northeast it is
expected to convert a lot of moisture from the gulf of Mexico into snow
and deposit it over southern Ontario. The resultant snow will begin to
accumulate over a corridor from Windsor to Toronto early this morning and
spread eastward by noon into the remaining warned regions.
Latest indications show the potential for significant amounts of snow from
this deepening low as it tracks northeast just south of lakes Erie and
Ontario towards New England by Saturday. This type of winter storm often
has a swath of 15 to 30 centimetres of heavy snow associated with it.
Freezing rain and ice pellets will also be a problem as the storm centre
gets close to the lower Great Lakes. The duration of ice pellets or
freezing rain could significantly lower snowfall amounts especially near
lakes Erie and Ontario however the result could be significant icing on
surfaces.
Latest analyses suggest the heaviest snow swath may extend from Lake St
Clair northeast across the London Kitchener and Golden Horseshoe areas
into eastern Ontario including the national Capital region. Storm total
snowfall amounts from a corridor from Bancroft to Ottawa could near 30
centimetres. The corridor from Barrie to Petawawa will see precipitation
mainly fall as snow with amounts near 25 centimetres. Ice pellets and
freezing rain may also be an issue to contend with generally in regions
near and southeast of highway 401.
Exact snowfall amounts and the location of ice pellets and freezing rain
will depend upon the exact track of this developing storm. It is also
possible if the storm centre tracks further north than expected that there
could be a changeover to rain especially in areas near eastern Lake Erie
and over Prince Edward county including Kingston.
There is a possibility of reduced visibilities due to blowing snow
especially this afternoon and through the evening.
This storm has the potential to be quite significant and have high impact
especially if heavy snow develops.

Winter storm watch for
Barrie - Collingwood - Hillsdale issued
A period of freezing rain is possible tonight.
This is an alert to the potential development of dangerous winter weather
conditions in these regions. Monitor weather conditions..Listen for
updated statements.
A powerful winter storm developing over the Prairies is moving eastwards
towards Ontario. As the warm front from the system sweeps across southern
Ontario tonight temperatures are expected to rise above the freezing mark.
As a result most of the precipitation from this system will fall as rain
over southern Ontario. However as it will take some time for the cold air
to be flushed out it is possible for the above regions to experience 2 to
4 hours of freezing rain late tonight before the temperatures rise to be
above the freezing mark.
At this point in time there is still some uncertainty as to where the
freezing rain will fall and for how long. When the situation becomes more
certain freezing rain warnings will be issued where required. Stay tuned
for updates. |

Winter storm warning for
Barrie - Collingwood - Hillsdale continued
A crippling Major winter storm with heavy snow and blowing snow as well as
some ice pellets is moving in right on schedule this morning.
This is a warning that dangerous winter weather conditions are imminent or
occurring in these regions. Monitor weather conditions..Listen for updated
statements.
A massive winter storm has begun over southern Ontario and the stage is
set for this dangerous storm to kick into high gear over the entire
forecast district today with near record snowfall amounts.
Latest analyses show a rapidly deepening low pressure centre now over
northern Ohio just southwest of Cleveland this morning. This low is
preceeded by an expanding area of heavy snow with some freezing rain and
ice pellets having mixed in at times as far north as the Windsor London
Kitchener and Toronto areas.
There have been several reports from the OPP of freezing rain and low to
almost nil visibility in heavy snow over southern Ontario earlier this
morning.
This intensifying winter storm centre will move towards Lake Erie then
northeast across western and then northern New York state to New England
by this evening. This storm track is placing southern and eastern Ontario
directly under the brunt of heavy snow. A few claps of thunder along with
bursts of very heavy snow are also likely and have already been reported
over southeastern Michigan and possibly southwestern Ontario early this
morning.
The main snow event has moved into southwestern Ontario now and will
rapidly expand and envelop all regions east to Ottawa this morning.
Copious amounts of snow as well as strong winds causing blowing snow are
expected. The snow will be mixed at times with ice pellets and freezing
rain along and south of a line from grand through the greater Toronto area
to Kingston and then along the St Lawrence river Valley to Cornwall.
Widespread snowfall accumulations of 20 to 30 cm are expected in most
areas by this evening. Some local amounts of 40 to 50 cm or more are quite
likely in a few areas..Especially from the west end of Lake Ontario and
eastwards into far eastern Ontario. Snowfall rates of 2 to 4 cm an hour
are expected with low to nil visibility in sustained bursts of heavy snow
likely.
Significant blowing snow is expected to accompany the heavy snow due to
strong northeast winds gusting to 70 km/h whipping up the freshly fallen
snow and causing whiteout conditions.
This is a dangerous winter storm. It is strongly recommended to avoid
unnecessary travel during this storm. This massive snow storm has the
potential to cause paralyzing conditions as road travel on any unplowed
streets becomes next to impossible today. All motorists who must travel
are urgently advised to use extreme caution and plan for much extra time
to reach their destination.
There remains a high degree of certainty with this storm as the the latest
computer model and observed trends continue to forecast this potential
record setting winter storm.
The storm is expected to move out over southern Ontario by this evening
with the heavy snow moving out of eastern Ontario by Monday morning as the
storm centre moves away over New England into the Maritimes. However
snowsqualls may form tonight to the Lee of Lake Huron resulting in a
continuation of locally dangerous winter travelling conditions throughout
the night. |

Winter storm warning for
Barrie - Collingwood - Hillsdale upgraded from winter storm watch
A near-crippling snow storm with heavy snow and blowing snow as well as
some ice pellets tonight and Sunday.
This is a warning that dangerous winter weather conditions are imminent or
occurring in these regions. Monitor weather conditions..Listen for updated
statements.
A massive winter storm is about to strike much of southern and eastern
Ontario with near record snowfall amounts. Latest analyses indicates that
the developing low pressure system is moving into western tennesee
preceeded by a burgeoning area of moderate snow with some freezing
precipitation extending north to Lake Erie.
The low will move northeast towards the lower Great Lakes and intensify
rapidly as it reaches Ohio Sunday morning then track across New York state
into New England Sunday night. This storm track will place much of
southern and eastern Ontario directly under the brunt of heavy snow. A few
claps of thunder along with bursts of very heavy snow are also likely.
Patchy areas of snow have affected portions of southern Ontario today as
well as a lake snow band meandering across Toronto. There is a chance that
this band may intensify this evening over Toronto giving locally 5 cm or
more. The brunt of the main snow event will begin this evening in the
southwest and rapidly envelop all regions east to Ottawa in the overnight
hours. Copious amounts of snow as well as strong winds causing blowing
snow are expected. Freezing rain is also possible near Lake Erie.
Widespread snowfall accumulations of 20 to 30 cm are expected in most
areas tonight and Sunday. Some local amounts of 40 cm or more are quite
likely in a few areas by Sunday night..Especially from the west end of
Lake Ontario and eastwards into far eastern Ontario.
Significant blowing snow is expected to accompany the heavy snow due to
strong northeast winds gusting to 60 km/h whipping up the freshly fallen
snow and causing whiteout conditions. In addition freezing rain is
possible especially near Lake Erie for a few hours overnight and Sunday
morning as milder air pays a brief visit aloft. Ice pellets are also quite
possible generally along and south of a line from Grand Bend to near
Toronto and east to Cornwall.
The public should be prepared to change plans accordingly to avoid
unnecessary travel during this storm. This massive snow storm has the
potential to cause near-paralyzing conditions as road travel on any
unplowed streets may become next to impossible on Sunday. All motorists
who must travel are urgently advised to use extreme caution and plan for
much extra time to reach their destination.
There is a high degree of certainty with this storm as the concensus of
weather model data is virtually unanimously forecasting this event.
Environment Canada continues to closely monitor this situation. The winter
storm warnings will likely be expanded northeast across the remainder of
the regions this afternoon. |

A major winter storm from Colorado is moving over the Great Lakes. This
winter storm has a large area of heavy snow and freezing rain associated
with it extending from the Colorado and Nebraska areas all the way up to
the Great Lakes and Northern Ontario. The leading edge of the snow has
already reached Ottawa this morning.
Over southwestern Ontario near Windsor and Sarnia freezing rain or ice
pellets have ended and showers is expected this morning. Regions north and
east of Windsor and south of a line from Goderich to Mount Forest to
Peterborough and over to Kingston will near 10 centimetres of snow
accumulations before becoming mixed with freezing rain or ice pellets
later this morning or midday. The precipitation will change over to rain
in the afternoon before changing back to snow tonight. Up to 20
centimetres of total snow mixed with ice pellets have already been
reported over areas close to the Niagara Escarpment.
Regions over eastern Ontario including Ottawa and Gatineau will continue
to see snow today with the heaviest snow falling tonight into Monday
morning. Snowfall amounts of 10 to 15 centimetres are possible by Monday
morning with an additional 10 to 20 by Monday evening.
Dangerous winter travelling conditions are expected across Ontario as the
snow may possibly be heavy at times which can cause brief whiteout
conditions. Furthermore roads will be snow covered and slippery due to
freezing rain and ice pellets. Travel plans should be altered accordingly.
At this point in time there is still uncertainty in the track of the low
into the Great Lakes this afternoon. If the low tracks further north a
higher percentage of the precipitation will fall as rain or possibly
freezing rain. Alternately if the low tracks further south the snowfall
amounts will be higher than currently indicated in the forecast. |
