It looks like we will have a predominately west to northwesterly flow across agricultural Manitoba during this forecast period. The upper level pattern has a large area of low pressure over northeastern Canada with a ridge of high pressure over the far western states. The flow in the upper atmosphere is riding over the western

We all knew that summer would eventually get here, but I don’t think anyone would have guessed that she would make such a grand entrance! Looking ahead to the next seven to 10 days, it looks like the early summer heat wave will be sticking around. Sunshine and hot weather will dominate the forecast region

Maybe I should be a pessimist more often. After months and months of trying to see the best possible outcomes in the weather models, last week I finally gave in, went to the dark side and what happens? The weather ends up taking the optimistic path! The big question that’s now on most people’s minds

Conflicting Areas Of Wind

At the end of our last weather school article I hoped that we would see an early strengthening of the subtropical high which would then hopefully bring a warm and early start to spring. Instead we saw what our part of the world is famous for, big intense areas of low pressure. This week in



Most Of The World Has Predictable Weather

Our little break from weather school seems to have stretched out for over a month now. Well, Reading Week (or should I say “Month?”) is over and it’s time to get back to work! In our last lesson we continued our look at atmospheric circulation, and in particular, we built upon our general model of

Last week we talked about arctic high pressure dominating the weather and it looks like the same thing will happen during this forecast period, at least during the first half. It is currently looking like a strong area of arctic high pressure will build southwards over Western Canada during this week. This region of high



General atmospheric circulation

After the last couple of weather school lessons on wind, we now have a basic understanding of what drives our winds. With this knowledge we are now ready to take this information and start piecing together the bigger picture of global winds, or what is referred to as general atmospheric circulation. We now know that

Gravity, pressure, Coriolis, friction = wind

The bigger the difference between areas of high and low pressure, the faster the air will move between them. Most public schools get a couple of weeks off over Christmas and some private schools will give three weeks, but here at Weather School we’re so nice that we give over six weeks of holidays from
