Warm air returns Sunday mainly south and east of Winnipeg..
A sharp frontal zone over northern North Dakota brought cloudy skies and rain over the Red River valley today, keeping afternoon temperatures only in the mid teens.. some 15C cooler than 24 hours earlier. On Sunday, this frontal zone will move back north as a warm front to lie across southern Manitoba by afternoon. Current indications are that this frontal zone will lie just south and east of Winnipeg Sunday afternoon, with temperatures reaching 30C south of this boundary over the southern Red River valley and southeast Manitoba. (see Sunday afternoon NAM temperature forecast image) Temperatures will be sharply cooler north and west of this front, with highs only in the mid teens to 20C along with occasional showers. At this point, it looks like most of this shower activity should stay north of Winnipeg.. good news for the final day of the LPGA golf tournament. However, the frontal zone will be close enough to the city to keep a threat of some showers, along with temperatures in the low to mid 20s (if we get some sunshine, 20c if we stay cloudy) This frontal zone will become stalled over the Red River valley Sunday night into Monday night with showers and thunderstorms moving in giving the potential for locally heavy rain as storms "train" along the stalled frontal zone.
