Yet another Colorado Low is set to impact the northern Great Plains late Friday through the weekend. Environment Canada has issued a Special Weather Statement for all of Southern Manitoba.
A third major low pressure system in as many weeks will impact parts of southeastern Saskatchewan and southern Manitoba bringing additional precipitation to areas already experiencing highly saturated ground and overland flooding.
Confidence is increasing that areas in the Red River Valley and western Manitoba will receive an additional 20 to 50 mm of precipitation, most of which will likely fall as rain on Saturday, although some snow is possible over the higher terrain of southwestern Manitoba and on the back side of the low on Sunday.
Areas near the international border will likely see greater total precipitation, possibly reaching 50 mm, while Winnipeg and the northern Red River Valley will likely see lesser amounts, in the 20 to 30 mm range. Southeastern Saskatchewan may see lesser amounts based on latest model trends.
