SEVERE STORMS SLAM ALBERTA SATURDAY

After what has already been a stormy night, Saturday afternoon's storms crossed the severe threshold in parts of Alberta once again, with at least one storm turning tornadic in the Lethbridge - Taber - Milk River area.

No tornadoes have been officially confirmed yet, but radar and spotters reported rotation, and the storms produced very heavy downpours, and large and damaging hail.

SUNDAY AND BEYOND: STORM POTENTIAL SHIFTS EAST, TEMPERATURES TO DROP

Alberta will finally get something of a break Sunday, at least from severe storms, though overnight storms may linger somewhat into the early morning hours.

Sater in the day, storm risk shifts further east into southern Saskatchewan and southwestern Manitoba, with the possibiltiy of some storms reaching severe limits, though presently looking to be less potent than on Saturday.

Sun PR risk

Meanwhile, there will be periods of widespread rain for the western Prairies, including central and northern parts of Alberta, which are already saturated from excessive rain over the past few weeks.

Beyond the weekend, a potent system tracks into Manitoba late Tuesday into early Wednesday, shifting into northwestern Ontario on Wednesday with heavy rain, strong winds and a risk for strong to severe thunderstorms.

Cooler than seasonal temperatures return to Alberta Sunday and most of next week, featuring several days with highs in the mid-teens for Calgary and Edmonton. Cooler weather will spread east across the region in behind the potent system. Warmer weather will then return to Alberta for next weekend.
