Forecast – for Dec. 16, 2010

This forecast period starts off a little tricky as the models are forecasting an area of low pressure to our west with a ridge of high pressure persisting to our east. The question is how far east the western low will be able to push and just where any snow will fall. Currently it looks

Big Snows Hit Ontario

Every so often a set of atmospheric conditions comes together to create some really remarkable weather. This is what happened last week in Ontario when cold northwesterly winds combined with the relatively warm waters of the Great Lakes to produce some remarkable snowfalls. Whenever there is cold air and warm water, you can get what


December To Follow November’s Pattern?

Before we dive into our monthly look back at the weather, I think I need to clear up a misunderstanding from the “probability of snow” article from a couple of weeks ago. A fair number of people have emailed me asking if there is such a low probability of getting more than 10 cm of

Drought Spreads Through China

Drought has affected winter wheat crops in 17 per cent of China’s wheat-growing areas in the country’s northern bread basket, and dry weather is forecast to extend until spring next year, the government said. But analysts said it was too early to predict how the overall wheat harvest in May would be affected, since irrigation


Weekly Weather Map – for Dec. 2, 2010

With early significant snowfalls across the Prairies it is time for the first snowcover map of the season. This map is created by Environment Canada but I do a lot of cleaning up of the map to try and make it more readable. During this process a lot of detail is lost so this map

Forecast – for Dec. 2, 2010

It is finally starting to look like our current weather pattern which has brought well-above-average snowfalls to most of agricultural Manitoba is going to quiet down a little bit during this forecast period. As what looks to be the last in a series of storms pulls away to the east on Wednesday we should see


Past Weather Does Not Always Mean Future Weather

Early in September I took a quick look at the kind of weather we might expect this winter. In particular, we examined the phenomenon known as La Nińa or the “anti El Nińo.” La Nińa is a cooling of the equatorial Pacific Ocean and when this occurs it can have an impact on our winter

Forecast – for Nov. 25, 2010

Another week has gone by and it looks like the weather models were fooled by Mother Nature. Last week I said the models were showing snow for our region late in the week and we did see some significant amounts of snow, but I also pointed out we would likely see things dry out after


Snowfall Days And Snowfall Events

Acouple of articles ago I wrote about when we should normally expect winter to start, and I added a little bit of information about the probability of receiving different amounts of snow in a single day. Well, it seems my snowfall probability comments have prompted a fair bit of discussion, as I have received a

Forecast – for Nov. 18, 2010

As we slowly move into winter it looks less and less like we will see a dramatic switch to full winter conditions. As each day goes by, the medium-range weather models show drier and drier conditions, along with only a moderate cooling trend. Earlier this month it was looking like the second half of November
