By 2pm it became clear that the risk had shifted well west of the original area of east central Saskatchewan as a massive supercell cluster had become severe thunderstorm warned in the Meadow Lake region. One lonely cell appeared west of Biggar at 2:10pm in a clear area between the rain complex to the north and extreme heat in the south. Only 20 minutes later that cell exploded to nearly reach maximum heights and severe thunderstorm watches were issued shortly there after.
As the afternoon Severe Thunderstorm Outlook Map was being built at that time, Saskatoon and area was added to the Moderate Risk area in orange.
