Winter Forecast 2010 - 2011

It is August already, a time when the winter forecasts are starting to trickle out by brave meteorologists who take a long shot at predicting snowfall amounts for the next six months. No longer are you dealing with short term weather models used for thunderstorms, but now you are dealing with long range weather models that track storms from the Pacific Ocean - all the way to Southern Ontario. Such examples of this would be the GFS model, the most accurate and up to date weather model out there............just kidding! Even the GFS can have a lot of fun taking people on emotional roller coasters. This model will predict a winter storm two weeks ahead for Southern Ontario, and then suddenly show this winter storm as a coastal blizzard, leaving Southern Ontario storm chasers reeling in amusement, and most times anger from all the false anticipation. I could go on and on about the weather models, but I'll cut to the chase. I have three winter storm forecasts that I would like to show you today. The first one will be done by Joe Bastardi, a well respected meteorologist; the second one will be done by Brett Anderson, a meteorologist who specializes in Canadian weather climate; the third one will be done by me, a meteo....well we won't get into that. Please scroll down for each individual map:
                                           
                                                                                     Joe Bastardi's Storm Track
                                                   

                                                                                     Brett Anderson's Storm Track



My Storm Track

 If we look at the first map, you will see that Joe Bastardi has a pretty realistic idea of the upcoming winter. This is what he says, " The Canadian winter will be harsh as last year's was gentle."

I agree with his idea of the 2010 - 2011 winter until it comes to his idea of snow for Washington DC and the surrounding areas. I think he has missed the possibility for some heavy snow in the Mid-Atlantic, which would be triggered by what we commonly know as the Alberta Clipper(see my map). Looking at history, an Alberta Clipper always intensifies after crossing the lower portion of the Great Lakes, and then sometimes increasingly intensifies after entering Virginia, due to warmer air from the south.

If we look at the next three maps by Brett Anderson, which predict the months of December, January, and February, you can see that Brett agrees with all of us about an active storm track for the western great lakes. I, however, do not agree with his prediction of an active storm track to the east during the month of December. It is to my belief, that December will be dry to the east because La~Nina conditions (Cooling of Pacific Ocean) will still be very weak by then. He doesn't agree with that, and believes that La~Nina conditions will already be in full force before December starts. In regards to that, I should mention that El~Nino(Warming of the Pacific Ocean near the equatorial line) is expected to fully dissipate during the next month or two.

I will sum it up with this, Southern Ontario will get some wet storms this year as we will be occasionally placed below the jetstream. Storms that start with rain, ice, and snow will not be uncommon for Southern Ontario this winter. The temperature will be above average for some of the regions in Southern Ontario, with a pretty large thaw taking place during middle to late January. The active storm track will stay west of Southern Ontario, with a few storms coming up along the east coast. Alberta Clippers will definitely not be uncommon for Southern Ontario, however the snow amounts will most likely stay below 10 - 15 centimeters.

I would like to mention one more possibility that might take place during February and March 2011. If you noticed, I have the Alberta Clipper track further south then most meteorologists would have it. In my opinion, the La~Nina could strengthen considerably by February or March, causing the jet stream to dip further south. If that happens, Southern Ontario could see more Alberta Clippers and possible colder air. This would not change my snow predictions for Southern Ontario due to the fact that Alberta Clippers don't usually deliver large amounts of snow.  A more indeph look at the winter forecast will take place closer towards the month of November.

I'm looking for forecasts as to the first frosts for Chatham-Kent, Ontario. Is there anybody predicting it?

thanks

Hello i live in Huntsville Ontario just east of georgian bay. Have any of you weather predictors taken into your ideas the fact that georgian bay and lake superior are much much warmer than usual. Have you factored in that scenario and winds from the north west?

Gerald:
The ECMWF long range weather model is showing the next couple of months to be warmer than usual, however I don't always put my trust into the ECMWF's predictions. Having said that, this model has held consistency in it's past several runs. I believe the first frost could start taking place in the beginning to mid-November. I will post as soon as Environment Canada starts issuing frost warnings.

Wendy:
As I mentioned in the winter forecast, I believe that this winter will be warmer than average for Southern Ontario. If this were to take place, then it would be safe to assume that the Great Lakes would have more time to slowly cool off. This is not saying that you won't get your share of heavy lake effect snow. It just won't be as bad as last year in your area. It's a good question though.

i live in brampton ontario and you are predicting a warm winter for souther ontario but what about snow fall totals i believe the temperatures will slightly above average and slightly above average snow . what do you think the the snowfall range will be i think 135-155cm this year what do you think

Gurtej101:
It is my belief that a lot of the winter storms we get here in Southern Ontario will be a mix of rain, ice, and snow. This is the direction the weather models are heading in, and most meteorologists would agree with me. The most active storm track this winter season will be through the Western Great Lakes. This would put cities such as Thunder Bay and Sault Ste Marie in a high snowfall zone. For cities such as Toronto and Brampton, it would be a wide mix of mostly rain, ice and wet snow. In conclusion, I believe that Brampton will recieve a less than average snowfall this winter season.

does sudbury ontario count in on the heavy snow too?

Weather Nut said...

Justin Makela:
The further west you go(within the Great Lakes region), the higher your snowfall amounts will be. This is due to an active storm track that will cut through the Western Great Lakes.

Do you have any comments about the prospects for Vancouver? I'm no meterologist but those charts seem to point to pretty cold weather and a lot more snow than normal? Is that right (madly looking for snow tire deals)?

Hi I am from Vancouver; it looks like more snow and cold weather than normal for us. Is that right?

Thanks

Hi there,

What do you predict for Burlington Ontario, will there be high amounts of snow? will it be cold or mild?

Peter:
My area of interest in weather forecasting does not include the other provinces of Canada. I would love to include these provinces, however the time and effort it would take to research and study the weather for these regions would be too much for me right now. I did hear about some potential snow for areas west of Vancouver this weekend. It might be interesting to keep an eye out for that.

My forecast touches base on the possible winter storm track for Southern Ontario(Burlington included). We are expecting a warmer winter for Southern Ontario with a lot of wet storms. These storms would include rain, ice and snow. During the period of cool air, typically in February and March, we are expecting a lot of Ablerta Clippers. Albert Clippers don't usually tend to give out that much snow due to their speed.

What about the "banana belt"....between Windsor and Sarnia......

Weather nut, what about windsor and chatham-kent area. I was really hoping for a lot of snow this year unlike last year. Is it the same, warmer n wet?

What about thornhill, barrie, and collingwood?

I live in London ON. Are you expecting a mild winter like last year or not? Please advise

sam said...

First, I would like to know what you consider normal temperatures and snowfalls for southern Ontario, having said that,how much less as far as temps and snowfalls could we hypothetically expect?

Hi weathernut,
What you consider a normal winter in terms of temps and snowfall for Brampton and the GTA? And how much less of those two do you feel this winter could bring?

Hey weather nut i live in Richmond Hill will it be good for outdoor ponds?

I have been hearing every where that it is going to be a snowy and cold winter. Why do you think it is going to be so warm? PS. I work at a place where they have to predict the winter forcast, and the folks at my work are predicting for more snow than usual and cooler temperatures since El Nineo. From Brantford Ontario

Note: In my new forecast I have since changed the warm winter idea.

Thank you, so then you think we will get a colder winter with more snow?

I live downtown toronto. i only drive 6K km/year and have fared alright without snow tires so far for a handful of years. will there be really bad weather this winter - should i buy snow tires? Looking forward to your updated forecast.
