UPDATE: Latest model guidance has shifted the track of Tuesday's system further south. As a result, the heaviest snow is now expected to fall over southwest Manitoba and over the southern Red River valley into SE Manitoba where 10-15 cm is possible. Winnipeg is expected to lie on the northern edge of the heaviest snow.. with 5 cm possible. Note that Winnipeg may get heavier amounts of snow if this system tracks a little further north than latest projections. Stay tuned..

By Tuesday, an Alberta clipper system will track through the Manitoba lakes and bring a threat of snow, especially through the Interlake areas. Gusty northerly winds on the backside of the system will draw in colder temperatures over southern MB by Tuesday evening, with temperatures finally dropping to normal or even below normal values for the beginning of December (normal highs -7C, normal lows -15C)

Models are indicating a nice warmup over southern MB by the end of the week, as a low pressure system moves across the northern Prairies spreading a mild Pacific airmass across much of the south. In southern MB, sunny skies and temperatures of 10 to 13C are likely by Friday into Saturday, well above the normal highs of +3C for early November. Temperatures will cool slightly for next week however long range guidance is suggesting that temperatures will remain near to above normal into mid November.
