Warm weather to continue

The first part of last week’s forecast played out pretty much as expected, but the second part of the forecast, well that was a bit of a bust! The upper area of low pressure did cross north-central Manitoba over the weekend, but it lost a fair bit of its energy as it did so. The

Severe thunderstorms and tornadoes

Since they can’t actually get inside to measure it, scientists aren’t completely sure what causes a tornado

We’ve seen a few thunderstorms over southern and central Manitoba so far this July, but most have not been very severe. That said, over the weekend, southwestern Manitoba had a tornado watch in effect and that reminded me that we need to finish our look at severe thunderstorms and in particular, tornadoes. The biggest question


Riding the edge of a heat wave

Last week’s forecast played out pretty much as expected, with the exception of a little more cloud and slightly cooler temperatures on Sunday and Monday, but after the dry weather and all the heat last week I think it was actually appreciated! It looks like the heat will be back on for most of this



Expert says climate change may be driving floods

Climate data suggests weather patterns are changing and flooding on the Assiniboine River may become more frequent, says John Pomeroy, director of the University of Saskatchewan’s Centre for Hydrology. It’s not just the three consecutive years of heavy spring rains that concern the professor, who is also a Canada research chair in water resources and

A July heat wave is possible

Summer weather definitely arrived last week with plenty of heat, humidity and even a few thunderstorms. It looks like this pattern will continue for much of this forecast period. Fortunately, it looks like we may miss the extreme heat the U.S. is experiencing during this forecast period, but it still looks like it will be


Should we expect a record-setting July?

Another month has come and gone. Those of you who felt June 2012 was actually a little warmer than average, were pretty much right — at least for most areas. The results of my June number crunching are below. June started off warm across most of southern and central Manitoba, with temperatures climbing near and

Floods drain Assiniboine farmers

Judging from the view of water covering a broad, green meadow of seeded cropland on both sides of the Assiniboine River here, the flood of 2012 is already underway. Near the town of Shellmouth, a little farther downstream, tiny canola plants are poking up through the mud of a broad flood plain. In the lower


Starting to understand tornadoes

This week we’ll continue our look at severe thunderstorms, and specifically, the most deadly part: tornadoes. What are tornadoes and how do they form? A classic definition of a tornado is a violently rotating column of air that extends from a thunderstorm to the ground, which may or may not be visible as a funnel

Pressure ridge may bring July heat wave

The weather models have been bouncing around over the last week, but over the last couple of days they seem to be coming into agreement on the forecast — and that forecast is for good old summer weather. The models show the upper ridge of high pressure, which brought plenty of sunshine and warming temperatures
