While yesterday’s storms didn’t quite cross the threshold of becoming severe, the chances for severe thunderstorms are much greater for today, as a low pressure system moves through Central Alberta. Areas north of the low, into Northern Alberta, can expect widespread rain today as the system tracks eastward, with up to 20mm falling, and an additional 20mm is possible on the backside of the system through the day tomorrow. Around the low and southward, however, severe thunderstorms are expected to dominate the afternoon and continue into the evening and overnight hours.

Isolated thunderstorms could start to develop as early as the noon hour, but the bulk of the storms are anticipated to begin in the mid-afternoon, around 2-3pm, and continue into the evening across Central and Southern Alberta as the low and its associated warm front cross through the region. The storms triggered by this front are expected to be isolated, with the environment favourable for the development of supercells, so the activity won’t be as widespread as seen yesterday.

A bit later in the afternoon, there is also a slightly higher chance that storms in Southeastern Alberta could become severe as they cross into Saskatchewan. This will be dependent on the southerly winds clearing wildfire smoke out of the area so that daytime heating can be maximized ahead of the warm front. Storm activity could continue overnight through parts of Saskatchewan, but they are expected to quickly lose strength later in the evening so any remaining storms should be sub-severe.

Today’s severe thunderstorms could bring damaging wind gusts up to, and possibly exceeding, 100km/h, along with heavy downpours and hail as large as ping pong balls. In the East-Central region of Alberta, from Edmonton towards Lloydminster and southward to almost Red Deer, the environment will also be favourable for the development of funnel clouds and there is a slight chance of a tornado forming.

There has been a major decline in the fire hazard across most of Central and Southern Alberta with widespread rain over the past couple of days. That trend will continue into parts of Northern Alberta with the significant rain that is expected to fall to the north and on the backside of the low pressure system that will track across the province today.

The storms that could to move into Southwestern Saskatchewan later today may also start to lead to a downtrend in the fire danger in that area. We could possibly see this trend continue tomorrow as the system is expected to cross through Saskatchewan, bringing additional thunderstorm activity to the southern half of the province and widespread rain to the north of the low.
