INTO FRIDAY: ANOTHER SOAKING RAIN, RISK OF SEVERE WEATHER FOR EASTERN PRAIRIES

Rain and thunderstorms will continue pushing over the eastern Prairies overnight Thursday into Friday. The greatest and most widespread impact from this system will be heavy rain across areas that could certainly use a break from the precipitation.

Areas stretching from east-central Saskatchewan and southern Manitoba, as well as northwestern Ontario, will need to be prepared for 20-40 mm of rain, with localized totals possibly exceeding 60 mm in some places.

In addition to the heavy rain, we’re on the lookout for potentially strong to severe thunderstorms as a warm front lifts into the region.

While forecasters expect the bulk of the severe storms to remain south of the border, we’ll have to watch out for the potential for heavy rainfall, strong wind gusts, and large hail. Heavy rain could lead to more flooding in Manitoba. Make sure you have a way to receive severe weather warnings in the middle of the night.

As the low continues to track north, precipitation on the north and western extent of the system is forecast to transition to snow Friday night into Saturday morning for northern Saskatchewan and Manitoba.

Gusty winds will sweep over the eastern Prairies as the low-pressure system pulls away from the area. Widespread wind gusts of 70-90+ km/h will cover portions of Saskatchewan, Manitoba, and northwestern Ontario heading into Friday evening.

OVERLAND FLOOD WARNINGS IN EFFECT FOR PARTS OF MANITOBA

This additional slug of rainfall prompted overland flood warnings for portions of Manitoba, including The Pas and Dauphin. Much of southern Manitoba remains under an overland flood watch, according to the province, including Brandon and the Winnipeg metro.

According to the provincial news bulletin, Manitoba’s hydrologic forecast center will update its water level forecasts to determine the effect the rain will have on the areas already experiencing flooding.

Officials say the Red River flood of 2022 is already the sixth largest on record by volume. Only the 1997 and 2009 floods were larger.
