The stormy weather on the eastern Prairies this week is being driven by an amplified pattern in the West as a trough sits anchored over the region. The good news is the heavy rain will ease in southern Manitoba and northwestern Ontario Tuesday after Monday’s bout of severe weather. The bad news is more rain is on the way for flood-stricken Manitoba, with another opportunity to see severe thunderstorms late week. More on what’s left Tuesday and what’s ahead this week, below.
TUESDAY AND BEYOND: HEAVY RAIN EASES OFF BEFORE NEXT SEVERE WEATHER CHANCE
The threat for severe thunderstorms eased off Monday evening in southern Manitoba and will wane in northwestern Ontario in the early overnight period as the stateside low continues lifting north in the aforementioned provinces.
The rainfall will begin easing off through Tuesday morning in southern Manitoba and northwestern Ontario with the departure of the system. Northern areas of Manitoba and sections in the top end of northwestern Ontario will see rain through the day, then subsiding in the overnight hours.
Through Tuesday morning, the remaining additional rainfall will come from isolated thunderstorms.
Localized flooding is possible in low-lying areas of northwestern Ontario, especially since the already saturated ground has little ability to absorb further rainfall.
"Watch for possible washouts near rivers, creeks and culverts," says Environment and Climate Change Canada in the warning. "Keep children and pets away from creeks and river banks."
Beyond Tuesday, another round of widespread rain and thunderstorms is expected mid- and late week. A threat strong to severe storms is possible for northwestern Ontario and southern Manitoba late Wednesday and Thursday.
Strong winds, torrential rain and hail are the primary concerns. The storm threat also could bring additional drenching rains for Manitoba, which is bad news for flood-plagued regions.
Heavy rain will also extend west across eastern and central Saskatchewan late week. However, very little rain is expected for areas where it is needed most -- southern Alberta and southwestern Saskatchewan.
