Forecast: Typical mid-winter weather

Issued December 31, 2016 – Covering the period from January 4 to January 11, 2017

After a fairly active last week of December, it looks as though January will start off on the quiet side. High pressure looks to dominate our weather pattern over the next week or two, with the main storm track expected to stay to our south. A ridge of arctic high pressure is forecast to slowly

Forecast: A battle between high and low pressure

Issued September 19, 2016 – Covering the period from September 21 to September 28, 2016

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


Weather forecast predicts slightly cooler-than-average temperatures

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

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

The Raynor’s farmland was completely dishevelled and a number of out buildings were destroyed.

Tornado among several storm events in the southwest

Two rural properties took the brunt of Manitoba's most recent violent weather episode

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

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? A classic definition of a tornado is a violently


General weather pattern remains the same

Issued: Monday, July 20, 2015 – Covering: July 22 – July 29, 2015

The overall weather pattern doesn’t look like it will change much during this forecast period. We’re currently in a pattern that has a moderate ridge of high pressure over central North America, with this high extending northwards to about the central Prairies. To our east and west are troughs of low pressure. The western trough

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

A slight chance of thunderstorms

Issued: Monday, July 6, 2015 – Covering: July 8 – July 15, 2015

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


This cornfield north of Miami was one of many pulverized by hail June 27. More fields received hail July 4.

Another week, another hailstorm

MASC is busy processing more hail claims, severe weather damage

Thunderstorms damaged more Manitoba crops July 4 — one week after a vicious hailstorm injured or destroyed crops from Roseisle to Winkler, running roughly parallel to the Pembina Escarpment. As of July 6 the Manitoba Agricultural Services Corporation (MASC) had received 164 hail claims on insured crops, said David Koroscil, MASC’s manager for insurance projects

The old weather pattern returns

Issued: Monday, June 29, 2015 – Covering: July 2 – July 8, 2015

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
