Markham, ON - It's always nice to see people wearing short-sleeved shirts. Today, in the GTA, people are wearing short sleeves (not me though)! Today at around 2 pm, temperature took a peak at 11 C (not as high as the forecasted 14 C , but still decent -- part of the reason was that the sun did not show up as much as we anticipated). Sorry to disappoint you all, but it is NOT going to last, not even on Wednesday like my previous blog had suggested. Computer models are showing the storm track just south of the GTA, brushing through Buffalo, Rochester, Troy, Albany, Watertown in New York State. This could only mean one thing (it could mean more, but in this case... ) , and that would be the GTA staying in the cold side of this system. Along with dropping temperature as the cold front passes through tomorrow morning, snow is going to result. In the Greater Toronto Area (GTA, I should have mentioned what "GTA" meant before this), rain will fall persistently throughout toninght, tomorrow morning, tomorrow afternoon, and early parts of tomorrow evening before finally changing over to ice pellets, freezing rain, wet snow, etc. Tomorrow night is going to be nasty with all kinds of mix precipitation, and late into the night (well, I'd say at around 3 AM EST? Maybe?) will completely turn into snow. The snow is going to be much heavier than what we had seen in the past couple weeks, when the lake effect snow showers affected northern outskirts of Toronto. This snow is going to stick to the ground, and it won't end until probably Thursday''s evening commute. It is just going to be nasty. It looks like as if the southern "snow accumulation line" (the line where snow accumulation gets over 2 cm), will run north of London and finds its way west to cities like Kitchener, Brantford, Cambridge, Hamilton, then runs through roughly at the New York-Ontario border on Lake Ontario, before finally tracking its way into Central Maine. What makes this storm even worse is that behind its set of cold fronts, northwesterly winds will settle, and lake effect snow will kick in to the leeward sides of the Great Lakes, and that will increase snow accumulation, and from an amateur meteorologist's point of view, a hard snowfall forecast. The "rough sketch", "blueprint" (whatever you want to call it) of the snowfall amount will be on my next blog entry (this blog would not allow me to enter so many characters).
