Fall is usually a tough time of year to forecast as we begin our shift from summer to winter. This year looks like it might be tougher than most, since our summer weather pattern was pretty unpredictable. We saw a little of this last week. The storm system that was forecast to track by to

Issued: Monday, August 3, 2015 – Covering: August 5 – August 12, 2015

By
While this summer’s weather hasn’t been the easiest to figure out, the weather models have been doing a pretty good job of getting the big picture right. This was the case once again for last week’s forecast as the upper low stalled out over Hudson Bay as expected, and brought cooler air and afternoon clouds

By
Displaced bales, crushed crops and chunks of metal scatter fields in the southwest as the area recovers from one of Manitoba’s largest tornadoes in recent years. A low-pressure system that moved in from Montana sparked the extreme weather, which also doused the Virden area with nearly 75 mm of rain. Quarter-sized hail was also reported

Instability and vorticity: The ingredients that make a tornado

Since they can’t get inside to measure, scientists aren’t completely sure how funnel clouds and tornadoes form

By
So far this month weather conditions have been fairly good for thunderstorms to develop with plenty of warm, humid air around. 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?

Temporary cool-down next week?

Issued: Monday, July 13, 2015 – Covering: July 15 – July 22, 2015

Last week’s forecast didn’t play out exactly as the weather models predicted, but that was not unexpected with the slack flow across our region. For those living in the south, the smoke cleared out for the most part, a little earlier than expected, and a slow-moving upper low allowed very warm and humid air to

By
Last week’s forecast played out pretty much as expected, with an area of low pressure pushing through a cold front, which brought a fairly wide outbreak of thunderstorms on Saturday and Sunday. Cooler temperatures moved in to start this week, which brought some relief from the warm and humid conditions. A typical slack and muddled

Our overall weather pattern seems to have slipped back into the same general pattern that prevailed for much of the winter and spring. That pattern had a persistent ridge of high pressure over western North America and a trough of low pressure over eastern regions. We were stuck between these two main features and our
