Unseasonably mild start to November for southern MB.. double digit highs possible through Remembrance Day
November is off to a mild start as a large upper ridge of high pressure takes hold over mid-continent, bringing an extended spell of above normal temperatures across the Prairies. Temperatures have soared into the mid to upper teens over North Dakota, southern SK and Alberta, with even some 20C temperatures in southern Alberta (21C in Pollockville, 20C in Drumheller) The mild weather will push into southern Manitoba over the next day or so as a warm front slowly moves north. This front was accompanied by extensive low cloud and fog today over southern Manitoba, which was slow to clear as increasing temperatures aloft produced a strengthening inversion that trapped the low level moisture much of the day. Gradually, this low cloud and patchy fog is expected to push north and clear during the night low as level southerly winds increase this evening. Note however, winds are expected to decrease overnight which may lead to additional low cloud and fog development in some areas early Friday. Friday should be a nicer day with morning cloud and fog patches giving way to a mix of sun and cloud, and highs finally reaching the double digits across much of southern MB. The nice conditions are expected to continue into the weekend with highs in the mid teens, possibly upper teens along the Pembina escarpment. A disturbance tracking up through the Dakota may bring some light showers Sunday night into Monday, but they shouldn't amount to much with a few mm possible. Mild weather should continue through next week with highs at or above the 10C mark through Remembrance Day, and nighttime temperatures at or above freezing. Note that the longest stretch of highs at or above 10C in Winnipeg in November is 8 days from Nov 2-9 1963. There's a possibility that Winnipeg could be challenging that record. Otherwise, enjoy the October like start to November!
