Now that a warm front has brought some heat back into Alberta, active weather returns. Severe thunderstorms are possible across Northern and Central Alberta this afternoon, and into Saskatchewan later this evening. Central Alberta, in particular, could see some especially strong storms today, complete with the risk of an isolated tornado.

There have already been some scatted showers in Northern Alberta this morning, mostly in the northwest. Further development of thunderstorms is likely across the region and into Northern Saskatchewan this afternoon. These storms are expected to continue through the evening and into the early overnight hours before tapering off. It’s possible that some of these scattered storms could become severe throughout the day, with the potential for strong wind gusts up to 100km/h, toonie-sized hail, and heavy downpours.

The main area of concern for today, however, is in Central Alberta. Thunderstorms are expected to initiate in this region in the early to mid afternoon, which will gradually track eastward through the remainder of the afternoon and into the evening and overnight.

These storms likely strengthen into strong supercell thunderstorms by the late afternoon, which brings a strong risk to an area from Olds to Drayton Valley and east towards Wainright. There is the threat of hail larger than golf balls, damaging wind gusts in excess of 100km/h, heavy rain, and even the risk of an isolated tornado. These storms could be a major issue for motorists, especially between Red Deer and Edmonton, as they are expected to cross the QE2 during the evening commute.

The severe weather threat should decrease during the late evening and overnight hours, with the storms weakening as they continue along an eastward trajectory towards Saskatchewan. There is still the chance, however, that an isolated storm could remain severe during this time frame, which could still have the potential to produce large hail and strong wind gusts. The tornado risk, however, will decrease greatly.
