By Monday, the eastern blocking pattern begins to weaken, allowing the trough at the back of the low pressure system to shift southward, directing heavier bands of rain into southern areas and the foothills.
Central Alberta can expect between 50-80 mm of rainfall from Friday to Monday.
Unlike last week’s storm, this system is less widespread, with the heaviest rainfall expected in a narrow band, resulting in more localized impacts.
