SUNDAY EVENING: SEVERE STORM POTENTIAL, UNSETTLED CONDITIONS
An upper-level trough with associated surface low-pressure system are going to bring unsettled, possibly stormy, conditions on Sunday evening.
As it tracks east of the Rockies, it will bring widespread, heavy rainfall across the northern areas of Alberta, Saskatchewan and Manitoba. A high pressure system situated over Hudson Bay will slow down its trek, thus increasing its totals through Monday.
For the southern areas of the Prairies, the risk for severe thunderstorms will pick up again in central Alberta and southern Saskatchwan. Storms may fire up in Alberta and Saskatchewan during the evening hours. There is the potential for the storms to track into western Manitoba during the overnight hours. The main hazards include large hail, heavy rain and strong wind gusts.
Images and videos showing hail blanketing parts of southern Alberta appeared on social media on Sunday afternoon.
The Weather Network meteorologist Tyler Hamilton explains that this significant amount of hail was produced because of high instability paired with a low freezing level and changing wind speeds with height.
“This allowed for healthy thunderstorm updrafts to produce copious amounts of hail,” Hamilton added.
