It was a mild day over southern Manitoba today with plenty of sunshine and a southwest flow tapping a mild Pacific airmass spreading across the Prairies. Temperatures rose to the 7C mark in Winnipeg, even with a coating of snow on the ground, while temperatures soared into the double digits over the snowfree southern Red River valley. Gretna at 12.4C set a new record for November 23rd, beating the previous record high of 7.2C in 1962. Pinawa (6.5C), Gimli (7.6C) and Fisher Branch (8.6C) also set new record highs today.
