It looks like this forecast period will start off with another Alberta clipper. This low is forecast to track across North Dakota on Wednesday, bringing a shot of light snow to southern regions of Manitoba. As with the other clipper systems, only a couple centimetres of snow are expected.
It doesn’t look as though we’ll see cold air move in behind this system, as the West Coast ridge of high pressure weakens, allowing our flow to become more westerly. Temperatures should moderate over the week, with high temperatures by the weekend climbing to around the -8 C range.
Central regions might see a little light snow on Saturday as a weak trough moves through, otherwise it looks like nice, quiet winter weather. A much stronger system is expected to move through central regions late on Monday and into Tuesday. This system will likely bring five to 10 cm of snow to extreme northern regions, with only a few flurries over southern areas. Winds ahead of this system will become fairly strong from the south. These south winds will bring in mild air and we could see temperatures pushing the 0 C mark on Tuesday.
Colder air will start moving back in behind this system as Arctic high pressure begins to sag southward again. We could see some more light snow late next week as a system develops to our south along the edge of the Arctic high, but confidence in this is not that high.
Usual temperature range for this period: Highs, -19 to -4 C; lows, -32 to -12 C.
