Patchy freezing rain, along with significant rainfall is expected to start tomorrow (Friday, April 22) as a Colorado Low is set to impact the region.
Environment Canada issued a special weather statement for the region Thursday afternoon which states, "patchy freezing rain with ice accretion up to 2 mm and total rainfall amounts of 30 to 50 mm are expected by the Saturday evening."
The latest system is expected to hit the region on Friday morning as snow, ice pellets, or freezing rain before changing to rain Friday afternoon.
Rainfall amounts of 30 to 50 mm are expected; however, locally higher amounts are possible, especially for areas near the Minnesota border due to isolated thunderstorms. The frozen ground has a reduced ability to absorb this rainfall.
