Blustery winds whip through eastern Prairies, may pose problems

Manitoba and northwestern Ontario seemed to have escaped the worst of the storm brought a damaging derecho stateside, but the rains certainly weren't helpful for the former, still dealing with an elevated risk of overland flooding. The good news is the rain is coming to an end Saturday, but persistent strong winds in behind the low could create ice buildup along the lake shorelines. Beyond, we’re looking ahead to more unsettled weather next week. What you need to know, below.

SATURDAY: RAIN EASES, BUT GUSTY WINDS CONTINUE TO POSE PROBLEM

As the centre of the lows continue shifting north into Manitoba and northwestern Ontario Saturday, the rain will continue to dissipate in the aforementioned provinces, eventually moving out by the evening hours.

Additional rainfall totals of 10-20 mm is possible for parts of northern and central Manitoba, with less than 10 mm for southeastern Saskatchewan and northwestern Ontario.

We’re not quite out of the woods just yet. Winds will be blustery through the day Saturday, in behind the system, with gusts of 50-70 km/h. This could be problematic for the lakes as the shifting winds may pile up ice along the shorelines. But the winds will begin to subside in the evening and overnight period.

Even though the rain is mostly over for the folks who’ve dealt with flooding in recent weeks, overland flood warnings and watches continue for much of southern Manitoba as waterways continue to run high with additional runoff.

Use extra caution near the eastern lakeshores, as persistent winds will cause ice to pile up against the shoreline. Residents are advised to take all necessary precautions to stay safe in these areas.

Behind the system, temperatures will fall significantly below seasonal on Sunday and Monday. Winnipeg’s predicted high of 10°C on Monday is just half of the city’s seasonal high of 18°C for the date.

LOOK AHEAD: BRIEF BREAK FROM THE RAIN BEFORE ANOTHER VOLATILE PATTERN SETS UP

A ridge building in behind this system will afford the eastern Prairies a few days of calmer weather before unsettled conditions build in for the second half of the week.

This unsettled pattern could bring a widespread chance for rain and snow to the Prairies, including drought-stricken areas in Alberta and flood-weary areas of Manitoba.

Not only is the prospect of additional rain bad news for flooded sections of Manitoba, but more precipitation will further hamper a spring planting season that’s already severely delayed.
