Weather: Hot weather looks set to continue

Forecast covering the period from June 9 to June 16

By
Well, the warm, dry weather won out in last forecast. All it took was a northward shift of a few hundred kilometres to go from highs in the upper 20s to highs in the low to mid-30s. The area of low pressure that was forecast to track through southern and central regions late last week
Skies cleared and arctic air moved in on May 26-27, leaving most regions of Manitoba with some frosted patches.

Will June showers follow May flowers?

Overnight freezes at the end of May were unusually long for that time of year

Another month is in the books, and it was another in a series of interesting months, weather-wise. May began where April left off, but since it was May, it felt even colder. Daytime highs struggled to make it into the low teens and overnight lows routinely fell well below 0 C. This all changed around May 11 when daytime highs began to warm

Weather: Below average to start, then warmer?

Forecast covering the period from June 2 to June 9

It continues to be a tough time for the medium-range forecasts. The weather pattern continues to oscillate between cool and unsettled and warm and dry as summer tries to gain traction. Last issue’s forecast did pretty well but missed just how cold it got last Thursday and Friday mornings. I also hedged my bets on
Much of Manitoba last week had the temperatures and conditions favourable for thunderstorms to develop — but was short on humidity.

How to break a drought

In a dry spell, storm systems don’t have much moisture to offer up as rain

By
Sometimes I really hate my early deadline — and this is one of those times. As I write this on May 20, I’m watching the weather to see just how much rain we might see from the trough of low pressure moving through the province over the May long weekend. So far, the first part

Weather: A below-average start, then warmer?

Forecast covering the period from May 26 to June 2

By
If we look back at last issue’s forecast, it turned out to be partly right. The western trough of low pressure did develop, but it ended up being not as sharp as originally forecasted. This meant it became a wider trough, which allowed the storm systems rotating around it to make their way into Manitoba.
Not all heavy rain events necessarily come from thunderstorms, but in this region, most really big rainfalls do.

How do huge rainfall events happen?

Warm air can hold a heck of a lot more moisture than cold air

By
We are finally beginning to see summer-like temperatures across our region and, along with the heat, a little more humidity. Despite some people getting a little grumpy about the cool weather pattern we’ve been in this last month or so, that cool weather prevented several regions transitioning from really dry to dangerously dry conditions. That

Weather: Generally warm with a chance for rain

Forecast covering the period from May 19 to 26

By
Sometimes with weather it is a matter of a few hundred kilometres, and that small change early on can magnify into big changes later in the forecast period. This is exactly what happened with the previous forecast. An area of low pressure, forecasted to impact southern regions early in the forecast period, was weaker and
Not every thunderstorm that develops becomes severe; much of our summer rainfall comes from garden-variety air mass thunderstorms.

Multi-year drought and severe thunderstorms

Short-lived air mass thunderstorms can’t vent their rising air from the top

By
Before we continue our look at thunderstorms, and in particular, severe thunderstorms, I think we need to talk a little bit about the drought conditions that have been slowly deepening across much of southern Manitoba over the last several years. At first glance, it appears that our current dry conditions began last summer after a

Weather: We’re not done with the cool temps

Forecast covering the period from May 12 to 19

The two big forecast questions for this forecast period are: Will we finally see some consistently warm temperatures? And are we going to see any significant precipitation — preferably in the form of rain? Well, to start off this forecast period, the weather models show seasonable temperatures as our region finds itself in a light
A forecast for a cool May usually points to a wet May, but where do we see any signs of wet weather ahead?

Will May weather return to above-average temperatures?

So far we’ve flipped into a cooler-than-average pattern much like February’s

By
April 2021 started off nice, with temperatures running well above average. Daytime highs were routinely in the 14 to 18 C range, making most of us believe the long- range forecast was going to be correct in its prediction for a warmer-than-average month. Then, on April 12, a storm system moved through, stalled out, reversed
