Hello folks, a week of extremely cold temps but no snow to talk about in the GTA for the most part, certainly not down here in Dundas/Hamilton. There was some light snowfall for Toronto mid-week and more significant falls in the shape of distinct lake-effect bands that affected Oakville over to Guelph and also East of T.O. up to Coburg which caused a huge pile up on the 401hwy.
It was extremely cold. Both Hamilton and Toronto early week had cold weather alerts in force and exposed skin the windchill which was down to -25 to -28c at one point started to suffer from the effects of the cold. Coldest daytime temp was -13c here, -20c by night. The coldest of the winter so far but not incredibly cold compared with a 'normal' colder Artic blast. And as i pointed out last week, the folks in Yellowknife would probably laugh at you!
It's currently -3c under cloudy skies ahead of the start of the week and a potential for a big news maker tomorrow. EC have an advisory out at the minute, which is likely one way or the other to be upgraded to a Watch/Warning later :

==discussion==
A low pressure system developing over Colorado will track toward
Southern Ontario tonight and Monday. Precipitation ahead of this low
will reach Windsor this evening, then the Toronto to Georgian Bay
area towards midnight, and finally the Ottawa Valley Monday morning.
Precipitation will start as snow, then change to ice pellets and
freezing rain. Precipitation will change to rain for most areas
Monday, except near the Ottawa Valley Tuesday. The main concern is
that the freezing rain may last for several hours before changing to
rain. Latest indications suggest that freezing rain warnings will
likely be issued for a large part of Southern Ontario later today or
tonight as the event draws closer.
Snow amounts with this system will vary. General amounts of 2 to
5 cm are expected south of a line from Southern Georgian Bay to
Kingston. From Parry Sound to Ottawa and Cornwall, 5 to 10 cm of
snow are forecast. The highest amounts are likely to be over the
Burk's Falls and Algonquin regions, which may see 10 to 15 cm or more
of snow.
The exact timing and amount of the precipitation will depend on the
track of the low. As this system is developing, there is some
uncertainty in the exact track of the low. Environment Canada is
monitoring this system closely and will issue further statements and
warnings as necessary.
Motorists and pedestrians are advised to be prepared for hazardous
winter travelling conditions due to the freezing rain and snow.
Untreated surfaces may become icy and slippery. Low visibility in
areas of heavier snow may also contribute to hazardous winter driving
conditions.
The public is advised to monitor future forecasts and warnings as
warnings may be required or extended.
Ice storms aren't a regular occurance for Southern Ontario and as you can imagine they cause major problems especially if your driving in it! Snow before is another hazard as it will freeze below the layer of Ice and then get washed into the Ice if the forecast is correct. As the advisory says considerable doubt at the minute as to how long the Freezing rain will fall versus Snow or Rain, but the potential is there for the morning rush hour for some fairly big problems.
I watched with interest the cold and snowy weather back in the UK last week. Not insignificant for some areas by the sounds of it, i know family in the Yorkshire dales had over 4ft. Back in Ayrshire, higher ground did have some large falls but most of populated areas SW of Glasgow had at most an inch to 3 from reports. I hope you finally broke your snowduck in Fife Graeme?
Won't be able to post on what happens tomorrow with the weather as i'm headed to Ottawa tonight for a conference until Thursday. Getting out of town before the storm hits or something like that.....looks like the Ottawa valley might actually stay all snow from this system so could be fun and games up there also.
Have a great week everyone. Take Care
